Way before the event that caused the special inspection, I documented I felt Perry was heading for trouble. Here is how I preemptively I documented my concerns.
"Here I am today (2/29)just before the special inspection was announced. I thought it fishy Perry was admitting all the inaccurate event reports on the same swipe. Bet you Perry thought the special inspection inspector outsiders wouldn’t have the same deal as the onsite residents. We will ignore all initial event report mistakes and inaccuracies. So Perry came clean on their own.
Perry must have been notified many days ago a special inspection was coming to their plant."

"So about 17 days from this Jan 29 leak and reactor vessel control fumbling...we got this new scram on two SRVs opening up.
NRC: you happy about this?"
(2/9 and 2/12)"I am disappointed the manual scam didn't come sooner. This is such a rare event, I am not sure their emergency procedures carry a specific event with two SRVs slamming open. You would think this is a so rare event and they never trained on it, they would emediately scram the plant. This guy is so infrequent it calls for a special inspection."

Begins Special Inspection at Perry Nuclear Plant
The Nuclear Regulatory Commission has launched a Special Inspection into two recent events, neither of which affected public health or safety, at the Perry Nuclear Power Plant. The plant is operated by FirstEnergy Operating Co., and is located in Perry, Ohio, about 35 miles northeast of Cleveland.Sounds like they didn't have valve position indication. They surmised SRVS were open because torus temperatures were screaming up.
On February 8, operators manually shut down the reactor when they observed an increase of the temperature in the suppression pool. The suppression pool is designed to condense steam and is also a water source for emergency cooling systems. While the reactor was shutdown, on February 11, there was a temporary loss of power to certain plant cooling equipment.A fairly large size team.
Operators were able to use a redundant system and restore power to the cooling systems.
“Even though the two events are not related we have questions related to the response of the equipment and operator actions. Our team of specialists in reactor operations and electrical equipment will review the technical details to better understand what happened,” said NRC Region III Administrator Cynthia D. Pederson.
The four-member inspection team began work on Monday and will spend time both on and off site conducting their reviews. After the inspection, a report documenting the team’s findings will be made publicly available.
