Japanese Nuclear Plant Security Black Hole

USA Wiki leaks to the rescue. No doubt since Fukushima Japan is highly vulnerable to a terrorist attack. If a terror attack would happen, there would be a terrible and disproportion response because the nation is so sensitive over nuclear issues.

It is amazing, the NRA isn't required to make mandatory reporting on nuclear plant security vulnerabilities.

I'll tell you what, the whole nuclear industry worldwide is threaten by this Japanese vulnerability...

***“I can understand there are concerns after terrorist attacks like the ones in Paris,” said NRA Chairman Shunichi Tanaka at a news conference on Nov. 18. “For now, we will tighten security measures by asking (for the) cooperation of related organizations like the police,” he said.
But the NRA’s recent decision to revise its requirements to cope with terrorism has fueled fears over potential attacks on Japanese plants. 
***The Japan Times asked the NRA and Tokyo Electric Power Co. to comment on Ban’s comments, but both declined.
***“The Islamic State has warned the pagan nation of Japan against further endangering lives of Japan’s citizens through Japanese support of the American crusade,” the jihadi extremist group said in the latest issue of its English-language online magazine Dabiq. 
Even before the Fukushima crisis, the U.S. expressed serious concern over the apparent lack of security at Japanese nuclear plants. 
In May 2011, the whistle-blower website WikiLeaks released a number of documents it claimed were cables sent from the U.S. Embassy in Tokyo to Washington in 2006 and 2007.
In one cable dated Feb. 26, 2007, the U.S. expressed concerns by reporting “armed national police are present at certain nuclear power plants . . . in Japan, but they do not guard all facilities and contract civilian guards are prevented by law from carrying weapons.” 
Another cable, dated Nov. 2, 2006, referred to an anti-terrorism drill held at a nuclear fuel reprocessing plant in the village of Tokai, Ibaraki Prefecture. It reported that some Japanese officials “pointed out flaws in the drill, saying it was unrealistic because participants had advance copies of the scenario.” 
Kevin Maher, who served as the minister-counselor for science and technologies and environmental affairs at the U.S. Embassy in Tokyo, was among the U.S. officials surprised to learn of the apparent lack of armed security guards at Japanese nuclear plants. 
In a 2003 meeting in Tokyo, Maher said he and a visiting White House official at the time urged senior officials at Japan’s now-defunct Nuclear and Industrial Safety Agency to deploy armed guards to tighten security. 
“We were explaining that you need to be prepared for an armed terrorist attack,” Maher said in a recent interview with The Japan Times. “Literally their answer was, ‘No, because guns are illegal in Japan,’ ” he added. 
Maher, however, stressed he now believes Japanese security measures at nuclear plants have been greatly strengthened under the NRA’s new safety standards and the more realistic crisis-management approach taken by the Abe administration.
Maher asserted that nuclear plants are now more tightly protected and there are many other “softer” targets in Japan that would be easier for terrorists…

Did NEI's Fertel Get Canned Over Budget Cutting Ideal


They need the next generation to take over. A good looking interesting young women needs to become the next NEI CEO.
US nuclear power trade group head to retire in 2016 
By Steven Dolley and William Freebairn | December 18, 2015 06:00 AM 
A new leader will head the US nuclear power industry’s powerful trade group when Marvin Fertel, president and CEO of the Nuclear Energy Institute since 2008, retires at the end of 2016. 
The nuclear industry, facing escalating economic challenges and rising operating costs, could tap an executive with Exelon, the largest merchant nuclear plant operator, to succeed him, Fertel said. He first revealed his retirement plans in an exclusive interview with Platts December 16.
Fertel, 69, said NEI’s board of directors has been notified of his decision and a search firm will provide a list of candidates for his replacement to the group’s executive committee. 
Maria Korsnick, NEI’s chief operating officer since mid-2014, “will be certainly one of the prime candidates in that search,” Fertel said. 
“I’m getting tremendous benefit from having her here working with me,” he said. 
“It’s a great asset to this organization having Maria work with us now, and it will be a tremendous asset if she gets the job, in that she’ll have so much experience with what NEI does, as well as all the great background that she has,” Fertel said. “We look at it as a really good thing.”
Fertel noted, however, that he will not make the decision on his successor. 
Natural gas brings clear benefits to New England Massachusetts’s 1970s moment (ANGA)

Massachusetts’s 1970s moment

On April 18, 1977 America was in the midst of an energy crisis and President Jimmy Carter delivered a televised speech encouraging energy conservation. It was a smart idea, and he famously wore a cardigan sweater on-air to drive home the point that even the White House was turning down the heat.
How times have changed. Thirty-eight years later, America largely controls its own energy future. In fact, American produced energy has changed the global energy picture in a fundamental way –  thanks to innovations that tapped our abundant natural gas supplies – lowering  costs for consumers, reinvigorating American manufacturing and reshaping how our leaders think about generating the energy we’ll need for continued economic growth.
The magnitude of economic growth, specifically in the New England region, relies largely on how this clean-burning natural gas will be transported from the Pennsylvania shale fields to the region’s consumers and businesses. The governors of the six New England states understand this, and are rowing in the same direction, strongly supporting efforts to get new, much needed pipeline infrastructure built in the region.
Which is why it’s curious that Massachusetts Attorney General Maura Healey took a trip in the way-back machine to grab a page from the 1970s energy playbook last month. That’s when Healey released the results of a study she commissioned finding that Massachusetts didn’t need additional natural gas infrastructure but instead could make due by increasing energy efficiency and encouraging electricity customers to scale back their use. The Attorney General appears to argue that Massachusetts doesn’t need more natural gas infrastructure and instead should don the proverbial cardigan, turn down the heat and conserve more.
The Attorney General’s report, and her position against the need for more natural gas infrastructure, is troubling for several reasons.  First, the study only looked at the electric power market, ignoring the needs of local natural gas utilities struggling to meet increased demand for natural gas from residents and businesses seeking to switch from oil to natural gas.
Second, the Attorney General’s report appears to ignore the environmental benefits that natural gas is bringing to the region, and will continue to do so. That’s because Massachusetts and regional utilities are meeting clean air targets by replacing coal and oil fired power plants with cleaner burning natural gas plants. But the lack of pipelines to get the natural gas where it’s needed will force Massachusetts to delay the opportunity for cleaner burning energy to keep up with freezing temperatures.
While everyone supports energy conservation – after all, it’s  good for both our planet and our wallets – we also must allow for continued economic growth.  The good news is that with natural gas we don’t have to choose between the two. Greater use of natural gas is reducing emissions and driving more efficient manufacturing while lowering energy costs for businesses and homes alike.
The reality is that businesses that can relocate or expand outside of New England are warning that the region’s high energy costs jeopardize their continued operations. High energy costs also can result in manufacturers shutting down or curtailing operations, and consumers, who have seen household incomes stay flat for a decade, are being hit by energy prices that are increasingly difficult to afford.
The benefits of natural gas for New England are clear:  more energy, fewer emissions, more jobs and lower energy costs. Fortunately, New England governors are working together to promote greater prosperity in the region by advancing infrastructure investment to get more natural gas to consumers. A more constructive option for the Massachusetts Attorney General, therefore, would be to join with other New England leaders to advance the region’s shared economic, energy and environmental goals with new natural gas infrastructure and other transmission projects

Prior to joining NEI, Korsnick was senior vice president of Exelon’s Northeast operations and acting chief executive officer and chief nuclear officer of Constellation Energy Nuclear Group. She is also executive director of the US nuclear power industry’s Fukushima Steering Committee, which is responsible for coordinating with the NRC the industry’s activities in response to lessons learned from the Fukushima I accident in Japan in 2011. Korsnick joined NEI in 2014. 

Before Fertel joined NEI’s predecessor organization, the US Council for Energy Awareness, in 1990, he held positions at Ebasco, Management Analysis Company and Tenera. 

He became vice president of nuclear economics and fuel supply at NEI when the organization was formed in 1994, and he was named senior vice president and chief nuclear officer in 2003. Fertel became acting president and CEO in 2008 before being elected permanently to the position by NEI’s board in 2009. 

During Fertel’s tenure, among other efforts, NEI has supported the licensing and construction of five new nuclear power units in the US. After the Barack Obama administration canceled in 2010 DOE’s project to build a geological repository for spent fuel and nuclear waste at Yucca Mountain, Nevada, NEI successfully sued the department in federal court to halt the collection of a fee imposed on nuclear-generated electricity to build the Nuclear Waste Fund that would have been used to pay for that project. 

NEI has also advocated for low-carbon portfolio standards and other policies to assist merchant nuclear power plants facing economic challenges from low natural gas and power prices, and coordinated enhancements of nuclear power plants’ ability to mitigate severe accidents similar to that at Fukushima under its Flex initiative. 

Fertel took the helm of NEI at the height of talk about a “nuclear renaissance” in the US, spurred by expectations of strong growth in demand as well as government support for new plants. Fertel saw those hopes sharply diminished as an economic contraction followed by a historic drop in the price of natural gas sent power prices plunging and reduced the need for new generation. In the past three years, Fertel and NEI have faced announcements that seven nuclear units in the US would shut. Just this year, Entergy has said it will close its Pilgrim and FitzPatrick units in Massachusetts and New York, respectively, because of financial challenges faced by merchant nuclear plants. Those units rely on wholesale market rates for electricity, which have tumbled, to make profits. 

The support for Korsnick, an executive at the largest US merchant nuclear unit operator, reflects the importance that the problems of the merchant fleet represents for the industry. 

She has recently been at the forefront of industry efforts to spread awareness of the issues facing the industry, and earlier this month she outlined an industry-wide initiative to improve the economics of nuclear plants by reducing costs and increasing revenue. 

Fertel’s departure from NEI had been rumored for years.

The Natural Gas Gang is Too timid.

Toshiba is a Stinking Dead Whale?

update 12/21

I told you it was coming:
Toshiba, Facing $4.5 Billion Loss, Plans Deep Cuts
Toshiba has been racked this year by one of Japan’s biggest accounting scandals, which has morphed into a broader crisis affecting nearly all its major units. Its shares plunged 10% Monday and have lost more than half their value since March.
 Scandal-racked company hopes to sell a majority stake in its health-care division and expects to cut 7,800 jobs 
Toshiba has been racked this year by one of Japan’s biggest accounting scandals, which has morphed into a broader crisis affecting nearly all its major units. Its shares plunged 10% Monday and have lost more than half their value since March. 
The company earlier said it was seeking investors for its Westinghouse nuclear subsidiary and its semiconductor business, and it is talking with Fujitsu Ltd. FJTSY -3.88 % about a possible merger of personal-computer units. 
Deepening problems in the company’s consumer electronics business are one reason for the losses, but tough market conditions for the company’s mainstay nuclear and semiconductor operations are also playing a role. Toshiba said sales would fall by 7% this year and projected an operating loss at its semiconductor unit, which has been hit by a slowdown in China and weaker growth in global smartphone sales. 
In the nuclear business, Toshiba’s Westinghouse subsidiary has struggled to win new orders for reactors since the Fukushima Daiichi plant disaster in Japan in 2011.


So Toshiba (Westinghouse/new Vogtle) is undergoing profound restructuring after their phoney financial disclosures. I just don't trust the Japanese(nuclear)after Fukushima and San Onofre steam generators. 

Basically Toshiba says their nuclear division is very profitable and at times carried all of the giant corporation. I just think the nuclear industry have become too dependant on the behemoths, they gouge the hell and overcharge the utilities. They grossly overcharge the utilities and they provide poor quality services without fear of reprisal. 

So why has the US nuclear industry placed themselves in this weakened and powerless position...

I get it, the cheapest price always wins out. Why is the nuclear industry so desperate? 

Just think about it, when is Toshiba going spin off their highly profitable nuclear sector?       
Toshiba likely to suffer huge net loss in fiscal 2015Kyodo
Toshiba Corp. expects a record group net loss of around ¥500 billion for the business year ending in March, as it makes greater efforts to streamline operations following its profit-padding scandal, a company source said Saturday.
The net loss, which will balloon from ¥37.8 billion for the previous year, will eclipse the current record of ¥398.8 billion logged in the year through March 2009 in the aftermath of the global financial crisis. Its operating loss for fiscal 2015 is expected to top ¥200 billion, against a profit of ¥170.4 billion for fiscal 2014, according to the source. 
Slated to announce Monday a restructuring plan for its home electronics business, including white goods, televisions and personal computers, the company will also unveil its earnings outlook for the current fiscal year, which has so far been withheld. 
As part of its restructuring efforts, the company is considering slashing several thousand jobs both at home and abroad, including some 1,000 jobs in Japan, sources familiar with the matter said. 
Toshiba is considering downsizing its Ome complex in western Tokyo, which is engaged in TV and PC development, according to the sources. 
It is expected to sell its TV plant in Indonesia while transferring a factory in Egypt to its local joint venture partner El Araby Group to pull out of TV production on its own.
Toshiba is also considering merging its PC business with those of Fujitsu Ltd. and Vaio Corp., which was spun off from Sony Corp. last year. Toshiba’s white goods operation may be sold to Sharp Corp. under another plan. 
The scandal, in which Toshiba repeatedly padded profits by deferring the booking of losses in infrastructure, semiconductor and PC businesses, has led the firm to revise downward its profits totaling ¥224.8 billion on a pretax basis from April 2008 to December 2014. 
In a related development, the Financial Services Agency, Japan’s financial watchdog, is arranging to prohibit Toshiba’s corporate auditor from taking new contracts for three months for negligence and failure to uncover the accounting irregularities, another source said the same day. 
Ernst & Young ShinNihon LLC will also face about ¥2 billion in surcharges, the first case under the revised Certified Public Accountants Law that took effect in 2008 following another accounting scandal, plus an order to improve its business, the source said.

Fire shuts down nuclear reactor in Belgium 
December 19, 2015 - 8:48:44 am\ 
Brussels: A nuclear reactor at Tihange power station in Belgium has been turned off because of a fire in the plant, media reports said Saturday.
Reactor unit 1 was automatically switched off during the fire on Friday evening, which occurred in a non-nuclear section of the plant. The incident did not impact workers, the public or the environment, operator Electrabel said, according to Belga news agency.
Tihange is located about 70 kilometers west of the German border town of Aachen.
Earlier in the week, the plant's reactor unit 2 was restarted after a nearly two-year shutdown despite the objections of neighboring German officials, who called the decision 'irresponsible'.
Electrabel said it put the reactor back online 'in complete safety'. The facility has long been criticized as a potential safety hazard, with Germany's North Rhine-Westphalia Environment Minister Johannes Remmel recently calling it a 'crumbling reactor' and accusing Belgian authorities of 'playing Russian roulette'.
  • Tihange 1: 962 MWe (1975)
  • Tihange 2: 1008 MWe (1983)
  • Tihange 3: 1015 MWe (1985)

Red Wing Minnesota 2760 North Service Drive / P.O. Box 15 55066
The 29th refueling outage of Unit 2 at Prairie Island nuclear plant was completed Dec. 6, Xcel Energy announced Tuesday. More than 1,000 contractors and employees replaced about a third of the fuel in the reactor, as well as replaced its main electrical generator and step-up transformer — work only possible when the unit is offline. 
Knowing these guys another oil pipe cracked and oil began leaking on hot piping or oil soaked insulation. The crack wasn't big enough to trip the turbine...
LER 15-003-00
On June 7, 2015, Unit 2 Turbine Bearing Oil Pressure was normal at approximately 19 psig. At approximately 05:00, the Unit 2 Turbine Bearing Oil Pressure started to decrease. The Unit 2 Turbine Bearing Oil Pressure decreased at an increasing rate until at 07:35 oil pressure sharply decreased from approximately 17.7 psi to a level that required a turbine trip (trip setpoint is 6 psi). Unit 2 Turbine Bearing Oil Pressure quickly recovered from a low point as indicated on Emergency Response Computer System (ERCS) of 4.3 psi at 07:36:19 to above 16 psi at 07:36:21. Turbine Bearing Oil Pressure was able to be maintained by the Turning Gear Oil Pump while the turbine was on turning gear at a nominal pressure of 21 psi. The Unit 2 Turbine was removed from the turning gear at 00:30 on June 8, 2015. The oil system was shut down a short time thereafter. Oil was drained from the Unit 2 Turbine Oil Reservoir on June 8, 2015 at 06:00. As a result of the investigation, the site identified a circumferential crack on a welded joint upstream of check valve 2T0-303 on June 8, 2015 at18:23. (Corrective Action Program (CAP) Action Request (AR) 1482236). The weld was repaired by Work Order 524416-06 on June 10, 2015. 
These guys have been continuously a problem plant for many years and decades. They are always in the reports.

Safety Relief Valves SRVs melted In Fukushima

updated 12/18

Main Steam Safety Relief Valves Buna-N thread seals

I was coached the regs says the drywell environmental design temp is 340 degrees.
I think the original SRV manufacture had the actuator design seals high temp consideration right. It speaks to how unthoughtful we have become with the design of safety equipment and replacement parts. The first swipe in designs stated the replacement seal was required to be asbestos. Who even cares what temperatures the drywell got with the severely temperature resistant asbestos.
I have written a lot up on VY SRV actuator problems in the final years of the plant. Got a 2.206 on it. Just do a goggle search on popperville, Vermont Yankee, Safety Relief Valves and buna-n or some combination. 

***This reminds me of the Buno-n material they put in the Vermont Yankee's SRV actuators. Basically only qualified to 140 degrees when they needed 400 degrees in it. Mysteriously put in type II valves when it should have been type 1 valves. VY did this intentionally and the NRC allowed them to get away with it.

Collectively and systemically I feel the industry and the NRC has been undermining safety environmental qualification across the board for many years now.   

Safety Relief Valves melted In Fukushima. 

Delay in cooling Fukushima reactor possibly due to melted rubber, says Tepco

Kyodo


The injection of water to cool one of the reactors that suffered meltdowns at the Fukushima No. 1 nuclear complex in 2011 was delayed because the rubber parts in valves used to reduce reactor pressure had possibly melted, the plant operator said Thursday. 
According to Tokyo Electric Power Co., the component that may have melted is part of a device used to open the so-called safety relief valve when steam building up inside the reactor pressure vessel needs to be released in an emergency. 
Tepco had been unable to explain why workers faced difficulty opening the safety relief valves of the No. 2 reactor, but the company now says “one of the reasons” may have been because the component melted and was not able to function properly. 
The temperature limit for the component was about 170 degrees Celsius, but Tepco found it was able to withstand that level of temperature for only several hours. 
The nuclear crisis began on March 11, 2011, when earthquake-triggered tidal waves hit the plant, flooding electrical equipment and leading to the loss of reactor cooling systems. 
The system that had kept cooling the No. 2 reactor ceased on March 14. Workers sought to inject water by using fire trucks, but could not do so because the pressure inside the reactor was too high. 
Tepco thus sought to open the eight safety relief valves by using battery power, but the operation did not go smoothly. After several attempts the valves were finally opened, enabling water to be poured inside the reactor. 
For a safety relief valve to open, it needs to be supplied with nitrogen gas through another valve, to which the rubber component in question is attached. But nitrogen gas might have leaked when the component melted, Tepco said.

More Indian Point Junk

Lots is nuclear plant issues with switchyard insulators. I was spot on with my guesses with what caused this.
Cuomo calls for investigation of Indian Point nuclear plant

Why doesn't Gov Cuomo order the plant to be shutdown. I doubt the governor actually has the power to do this. Its called ceremonial or the power of influence and position. You don't need rules for the use of these kind of power. I doubt Entergy would operate a plant contrary to the started wishes of the Governor.    
"The company said workers replaced several electrical insulators on a high-voltage transmission line this week prior to returning Unit 3 to service. Insulators protect transmission lines and related electrical equipment from the high-voltage associated with each line.
Next, engineers will examine the replaced insulators over the next few days to help determine the cause of the electrical disturbance, company officials said." 
My guesses.
"Their switchyard is a wreck."  
"Maybe the insulator..."
Reposted from 12/15

Hmm, getting this might be undetected damage from the transformer fire...

Maybe the insulator...

The first Indian Point trip this month. Hey, at least River Bend is still up to 100% power. Humm, vibrations with a main coolant pump. They lose a blade?

Entergy: Indian Point nuclear power plant shut down due to electrical issue

Officials say one of the Indian Point nuclear power plant's reactors in suburban New York has been shut down due to an electrical disturbance.

BUCHANAN, N.Y.
Officials say one of the Indian Point nuclear power plant's reactors in suburban New York has been shut down due to an electrical disturbance. 
Governor Andrew Cuomo said in a statement that “Because of the number of recent unplanned outages, the Nuclear Regulatory Commission's requirements will result in increased inspections and scrutiny of the plant. A thorough investigation of this shutdown is underway and we will make sure the safety of New Yorkers is not compromised.” 
Plant owner Entergy says the Indian Point 3 reactor was automatically shut down at about 7 p.m. Monday. The company says the disturbance on the non-nuclear side of the plant is related to a high voltage transmission line. There was no release of radioactivity and no threat to the public. 
The Indian Point 2 reactor was shut down for three days earlier this month due to a tripped circuit breaker. The two reactors together supply about one-quarter of the power used in New York City and Westchester County. 
The nuclear plant is located in Buchanan, about 30 miles north of midtown Manhattan.

AUTOMATIC REACTOR TRIP DUE TO MAIN GENERATOR LOCKOUT

"At 1906 [EST] on 12/14/2015, Indian Point Unit 3 received a Main Generator Lockout trip signal, and the reactor automatically tripped. Site personnel reported seeing arcing on a 345kV output transmission line tower. At the time of the trip, there was moderate rain and fog in the area. The site fire brigade leader investigated the reports of arcing and found no evidence of fire; fire brigade response was not required.

"All automatic systems functioned as designed and all control rods inserted automatically. Auxiliary Feedwater Pumps started automatically due to expected low steam generator levels following a reactor trip from 100% power. Unit 3 is being maintained in Mode 3 with decay heat removal via steam dumps to the condenser. Offsite power remains available and in service from 138kV to the 480V safeguards buses. The cause of the Main Generator Lockout signal is being investigated.

"Unit 2 was not impacted and continues to operate at 100% power.

"The NRC Resident Inspector has been notified."

After the trip, operators observed high vibrations on the 33 reactor coolant pump which eventually returned to normal range.

The licensee will be notifying the New York Public Service Commission and their local Independent System Operator. A press release will be issued by the Communications Department.


"Gov. Andrew Cuomo calls it another unexplained incident and has ordered the state Department of Public Service to investigate
“Because of the number of recent unplanned outages, the Nuclear Regulatory Commission’s requirements will result in increased inspections and scrutiny of the plant,” Cuomo said in a statement. “A thorough investigation of this shutdown is underway and we will make sure the safety of New Yorkers is not compromised.”"

Swedish-Westinghouse Nuclear Vessel Problem

Supposedly Something new? Swedish?
Additional vessel inspections delay Beznau 1 restart
Dec 2, 2015
During a scheduled outage that began in May, inspections were made of the Beznau 1's RPV using state-of-the-art ultrasonic equipment. Axpo said these measurements "registered findings at some points in the base material of the block 1 RPV indicating minimal irregularities in the fabrication process". It conducted further measurements and analyses "in order to assess these in compliance with current regulations" and submitted a report to Switzerland's Federal Nuclear Safety Inspectorate (ENSI).
In July, Axpo announced that the restart of unit 1 had been postponed while the flaw indications were investigated further. At that time, the unit's restart was expected to be postponed until the end of October. However, in August ENSI called for additional investigations.
Axpo yesterday submitted a road map to ENSI for the further analysis and testing process on the unit's RPV.
Axpo said it is assessing additional measurements made with "a special testing method developed for a Belgian reactor" - a reference to work led by Belgian utility Electrabel to investigate a similar issue at Doel 3 and Tihange 2. Axpo noted that so far these results confirm the findings of earlier measurements. The company plans to submit a new, provisional test report later this month to the Swiss Association for Technical Inspections (SVTI/ASIT) and then to ENSI.
ENSI said it will now "review the plan for completeness and assess the extent to which the method chosen appears suitable for delivering reliable results on the integrity of the reactor pressure vessel". The regulator will subsequently issue a review report.
An extensive analysis and testing phase taking several months will be carried out by an international committee of experts nominated by ENSI. After reviewing Axpo's project plan, the committee will review the company's analyses and safety case.
ENSI deputy director Georg Schwarz said, "We will incorporate the experts' recommendations into our safety evaluation report. ENSI is solely responsible for the regulatory decision as to whether Beznau 1 is allowed to resume power operation."
Axpo said that, based on the current results, it "remains convinced that unit 1 will go back on grid after completion of the testing phase." However, it said that restart approval is not expected before the end of July 2016.
Meanwhile, Axpo said ultrasonic measurements on the RPV of Beznau 2 - which has been offline for a scheduled maintenance and upgrade outage since July - are "in an advanced stage". It noted the unvestigations so far have only resulted in "minute findings, which ... are normal based on their number and location".
Axpo said it will submit a test report on its unit 2 investigations to SVTI/ASIT "in the next few days".
It noted, "At present, nothing should stand in the way of the scheduled restart at the end of December 2015 following the completion of the unit 2 revision."
The two 365 MWe Westinghouse units at the Beznau plant are the oldest power reactors in Switzerland. Unit 1 began operating in 1969, while unit 2 entered operation in 1972. In addition to providing power, both units also produce district heating.
