| ENS 54740 | Seabrook | 6 June 2020 13:20:00 | Manual Reactor Trip When Group One, Bank 'B' Control Rods Inserted Into the Core | At 0920 (EDT), with the unit in Mode 1 and 100 percent power, the reactor was manually tripped due to group 1 of control rod bank 'B' fully inserting into the core. All systems responded normally post trip. Operations has stabilized the plant in mode 3 at NOP/NOT (normal operating pressure and temperature). Decay heat removal is being accomplished via the steam dumps in the steam pressure mode to the main condenser.
Emergency feedwater actuated due to low low steam generator level as expected.
This event is being reported pursuant to 10CFR50.72(b)(2)(iv)(B) and 10CFR50.72(b)(3)(iv)(A)
The senior NRC Resident Inspector has been notified.
The plant response to the trip was uncomplicated. All safe shutdown equipment is available. There were no reliefs or safeties actuated during the transient.
The licensee manually tripped eight days ago for the same condition. See EN #54731. |
