----------- [ Current event for MA_Pilgrim_1 ]

20190108 | MA_Pilgrim_1 | REACTOR CORE ISOLATION COOLING DECLARED INOPERABLE |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53818

"On January 8, 2019, at 0945 EST
Pilgrim Nuclear Power Station discovered that the Reactor Core Isolation Cooling (RCIC) system
failed to meet its surveillance test requirements and was declared inoperable;

therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v),
'event or condition that could have prevented the fulfillment of a safety function: (D), mitigate the consequences of an accident.'

"There was no impact on the health and safety of the public or plant personnel.

The NRC Resident Inspector has been notified."

[ Some info on the RCIC ]

[ Depending on the cost of repair this may not be repaired due to the fact that Pilgrim is slated for permanent shutdown in Jun of 2019. ]

----------- [ Current event for GA_Hatch_1;2 ]

20190108 | GA_Hatch_1;2 | INVALID SPECIFIED SYSTEM ACTUATION |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53817

"On November 12, 2018, at 1331 EST,
Unit 1 secondary containment isolated and Standby Gas Treatment (SBGT) systems started on Unit 1 and Unit 2 due to a blown fuse.

The blown fuse was caused by a degraded refuel floor radiation monitoring relay,
causing the radiation monitor to trip and resulted in an invalid actuation of the Unit 1 Group 10 and
Group 11 primary containment isolation valves, all Unit 1 secondary containment isolation valves,
and auto start of the Unit 1 and Unit 2 SBGT system.

The Unit 1 Fission Product Monitor isolated and tripped and both Unit 1 H202 Analyzers isolated.

"This event is reportable per 10 CFR 50.73(a)(2)(iv)(A) since the containment isolation and auto-start of SBGT on both units was
not part of a pre-planned sequence and the event resulted in the invalid actuation of general containment isolation valves
in more than one system.

"All primary and secondary containment isolation valves, with the exception of the 2T41F003A,
Refueling Floor Inboard Vent Supply Isolation valve, functioned successfully.

The refuel floor inboard vent supply isolation valve failed to travel fully closed on the secondary containment isolation signal
and was therefore declared inoperable.

The 2T41F003B refuel floor outboard vent supply isolation valve was verified to go fully closed
and therefore isolation of that associated penetration line was successful.

After assistance from maintenance, the valve was verified to be fully closed.

"All SBGT systems functioned successfully.

The associated fuse and relay were replaced, and secondary containment was returned to normal service.

"The licensee notified the NRC Resident Inspector."

20190108 | PA_ThreeMileIsland_1 | Update FITNESS-FOR-DUTY TEST POSITIVE FOR NON-LICENSED EMPLOYEE |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53552

EN Revision Imported Date : 1/9/2019

EN Revision Text: FITNESS-FOR-DUTY TEST POSITIVE FOR NON-LICENSED EMPLOYEE

At 1519 EDT on August 16, 2018, Exelon determined a non-licensed employee had a confirmed positive for a controlled substance during a random Fitness-for-Duty test. The employee's unescorted access to the plant has been terminated.

The NRC Resident Inspector has been notified.


* * * UPDATE FROM MICHAEL FITZWATER TO DONALD NORWOOD AT 1310 EST ON 1/8/2019 * * *

The following is a correction to the reason for the Fitness-for-Duty test:

At 1519 EDT on August 16, 2018, Exelon determined a non-licensed employee had a confirmed positive for a controlled substance during a follow-up Fitness-for-Duty test. The employee's unescorted access to the plant has been terminated.

The NRC Resident Inspector has been notified of this correction.

Notified R1DO (Bower) and FFD E-mail group.
