EN Revision Text: AGREEMENT STATE REPORT - LEAKING CHECK SOURCE
The following was received from the State of Washington via email:
"Framatome notified the State of Washington of a leaking 5 microCi Cs-137 check source that was identified on 8/17/2020. A set of stack samples showed evidence of Cs-137 contamination, leading the Radiation Safety Officer for the licensee to contact the Radiological Safety Supervisor to investigate into the possibility of a leaking Cs-137 check source. A visibly damaged source was identified and a leak test of the source revealed 0.02 microCi of removable material. The source storage area was surveyed to determine if there was any additional contamination, but none above the licensee's limits for action was identified. The source was contained and placed in storage to be held for disposal."
Washington Incident No.: WA-20-017
* * * UPDATE ON AUGUST 26, 2020 AT 1250 EDT FROM ANDREW HALLORAN TO BRIAN LIN * * *
The following information was received from the State of Washington via email:
"The leak test was performed in accordance with approved procedures using an instrument that was appropriate and in calibration. The source was part of a source jig used for routine instrument checks around the site. According to the Radiation Safety Officer, the source was likely damaged from impact against a hard surface during routine use."
Notified R4DO (Kellar) and NMSS Events Notification (email).
* * * UPDATE ON MARCH 9, 2021 AT 1838 EST FROM ANDREW HALLORAN TO BRIAN LIN * * *
The following information was received from the State of Washington via email:
"The source has been removed from service to be sent for disposal with the next waste shipment. Source manufacturer - The Nucleus. Serial number - SB-D14. Activity - 5 microCi."
Notified R4DO (Josey) and NMSS Events Notification (email).

MANUAL REACTOR TRIP DUE TO RISING STEAM GENERATOR LEVEL
"On 08/17/20 at 2113 EDT, with Unit 3 in Mode 1 at approximately 92% [Rated Thermal Power] RTP, the reactor was manually tripped. This was due to a turbine runback caused by CV-3-2011, Low Pressure Feedwater Heater Bypass Control Valve, failing open, followed by rising Steam Generator (S/G) levels. Unit 3 reactor was tripped manually when the 3C S/G Level reached 78% narrow range. Unit 3 Main Steam Isolation Valves were closed manually in accordance with Emergency Operating Procedure (EOP) network due to 38 MSR Main Steam Stop valve position indication lost. All other systems operated normally. Auxiliary Feedwater initiated as designed to provide S/G water level control. EOPs have been exited and General Operating Procedures (GOPs) were entered. Unit 3 is stable in Mode 3 at normal operating temperature and pressure.
"This event is being reported pursuant to 10 CFR 50.72(b)(2)(iv)(B) and 10 CFR 50.72(b)(3)(iv)(A).
"The NRC Resident Inspector has been notified."
All rods are inserted, decay heat is being removed via S/G through normal secondary systems. The plant is in normal electrical line up. Lightning strike is believed to be the initial cause of the runback.
