NOAA Says The Two Plant Bunkswhick Nuclear Plant Are Heading For a Meltdown in a Cat 4 Hurricane

Still working on this

Cat 4 Hurricane Hugo had a storm surge of 18 feet in North Carolina. I don't know if it was in the high or low end of a Cat 4 hurricane? Remember Florence is 21 feet about sea level. You know, what is your definition  sea level?  There is many of them. I got my measurement of Brunswick's above sea-level height of 21 feet from google earth. I kinda thought over topping the Brunswick's site was not probable in a Cat 4 or 5 hurricane. I did not believe these plants could be constructed so closes to sea-level. I figured these plants could easily survive high in the Cat 5 level. I now know it is probable ocean overtopping the site in a cat 4 or 5 is a certainty. I totally believe the NOAA's cat 4 or 5 storm surge calculations. Remember the hurricane ocean over topping is 3 feet at Brunswick per NOAA.

I am shocked at this latitude this plant is so poorly situated. I suspect more plants are in the same situation.

Now I consider it a high probability there will be a guaranteed of meltdown at Brunswick in a cat 4 or 5 hurricane. This is our Fukushima. Are the reactor building, turbine building, diesel generator rooms or the switchyard are not designed for a 6 feet or more ocean over-topping of their site. Can the flex system over come this kind of defect with a 6 feet or more over-topping of their site. In the best of any ones computer models, they is just too much uncertainty.

I think the turbine building and reactor building would quickly fill up with ocean water rendering all ECCS inoperable. I think the ECCS safety busses are on the ground floor. They would become inoperable. As far as the diesel generators, they are probrably on the ground floor. Certainly the diesel generator's local breakers are on the ground floor. There is your blackout where the flex system being useless too. You going to helicopter a flex system big DG or pump into 6 feet of water?  

I make the case in climate change, these big hurricanes will be much more probable.

Questions

1) Is it in plant licensing all US are nuclear plant are supposed to survive all cat 4 and 5 Hurricanes without a meltdown?

2) Think about the movement and safety of operators on site in a over-topping conditions. There would be no movement.

3) Would the hardened vent be usable or accessible?

I request a emergency investigation on this Hurricane ocean surge issue on a Cat 4 and 5 levels at Brunswick. Can this plant survive a Cat 4 or 5 hurricane without a meltdown? Is there a extremely high likelihood these plants would not meltdown? Actually, if a plant can't survive a Cat 4 or 5 hurricane without meltdown, these plants should be emediately shutdown in the greater interest of the USA?

I am considering a 2,206?

Preparing for Hurricane Florence The Nuclear Regulatory Commission resident inspectors at nuclear plants in the Carolinas and Virginia are reviewing the plant operators’ preparations in advance of Hurricane Florence, currently projected to make landfall in the Southeast later this week. 

The NRC is also sending additional inspectors to those plants and will activate its regional incident response center in Atlanta, to provide around-the-clock staff support during the storm. 

Duke Energy’s Brunswick nuclear plant south of Wilmington, N.C., could face hurricane-force winds, major storm surges and heavy rain. Other plants near the storm’s projected path are also taking precautions.

Nuclear plant operators would declare an emergency if conditions are expected that would require that declaration.

Plant procedures require operators to shut down the reactor well before hurricane-force winds arrive on site. In preparing for Hurricane Florence, the staffs at Brunswick, Surry in southeastern Virginia, Harris near Raleigh, N.C., Robinson near Hartsville, S.C., and some other plants are working through their severe weather procedures, including ensuring that all loose debris and equipment have been removed or secured, and conducting walk-down inspections of important systems and equipment. 

NRC inspectors are verifying that all preparations have been completed, and the plants’ emergency diesel generators are available with ample fuel if the storm affects off-site power. 

The NRC has also been in touch with officials at the Global Nuclear Fuels-America facility near Wilmington, N.C., the research reactor at North Carolina State University in Raleigh and other NRC licensees in the area to verify their preparations for the storm. 

From the NRC Region II incident response center in Atlanta, NRC staff members will monitor Hurricane Florence while remaining in contact with plant operators, NRC on-site inspectors, the NRC’s headquarters operations center, and state emergency officials in the Carolinas, Virginia and all potentially affected states. 

The additional NRC inspectors will remain at the nuclear plant sites and the incident response center will remain staffed as long as conditions require. 

Ok, do a google satellite search on the two plant Brunswick nuclear facility. Carefully memorized the  two canal entrench and discharge from the plant. This is very important. Then do a search on Southport NC on the NOAA hurricane surge page. Increase the magnification all the way down to where you can only see the street level detail on the map. You do not want to see any of the colors of the hurricane surge levels. Carefully going a little north, find the canals ends going into the plant. They erased any indications of the plant for bogus security consideration. All you can see is the canals ends. Or it is plainly a cover up with the risk of a possible meltdown risk. Find the two ends of the canals...the empty space between the canal ends is the plant. Remember what you seen in the google street search. Now decrease the magnification until the hurricane surge color levels appear on the NOAA page. On the top of the NOAA page are links to the Cat 1, 2, 3, 4 and 5 hurricane  surge levels. Click on the cat 3, 4 and 5 hurricane surge levels. Now do you see the site water inundation level. It says the site is going completely covered on cat 4.    

Update Sept 12

NOAA says for a Cat 4 hurricane, the site is going to be inundated by 3 feet water. A cat 3 might not get inundated but it will be a close call.

Should the site now be in a anticipatory site area emergency in preparation for a two plant meltdown. They would absolutely change the nation. 

It will be like Fukushima where the meltdown overwhelms the recovery actions.    

Wrightsville Beach might get a 13 feet surge. Multiple tide surges. Cape Fear river. The might regret building those intercoastal canals to the plant? 

The plant is 23 feet above sea level.
