20190606 | PA_Susquehanna_2 | 60-DAY OPTIONAL TELEPHONIC NOTIFICATION DUE TO INVALID SPECIFIED SYSTEM ACTUATION |
https://www.nrc.gov/reading-rm/doc-colle...ml#en54103
[ RFOD_033; RX_Mode; Cold Shutdown; Cold Shutdown ] [ event date 20190418 ]

"This 60-day telephone notification is being made in accordance with the reporting requirements specified by 10 CFR 50.73(a)(1)
and 10 CFR 50.73(a)(2)(iv)(A) to describe an invalid actuation of a general containment isolation signal
affecting multiple Main Steam Isolation Valves (MSIVs).

"On April 18, 2019 at approximately 0110 EDT,
during performance of an ASME reactor vessel leak check, [ prior to RFO exit ]
all four inboard MSIVs closed as a result of actuation of the Main Steam Line (MSL) high flow instrumentation.

The high flow signal was spurious on the 'D' channel with no flow in the MSLs.

Since an actual high flow condition did not exist at the time of the actuation, the actuation was considered invalid.

The MSIVs functioned as designed on actuation of the MSL high flow instrumentation.

All outboard MSIVs were closed at the time of the actuation in accordance with the vessel leak check procedure.

"The NRC Resident Inspector has been notified."

20190606 | SC_Summer_1 | Retract POTENTIAL MISSED SURVEILLANCE FOR ISFSI |
https://www.nrc.gov/reading-rm/doc-colle...ml#en54075


EN Revision Imported Date : 6/7/2019

EN Revision Text: POTENTIAL MISSED SURVEILLANCE FOR ISFSI

"At approximately 1833 EDT on 5/20/2019, VC Summer Nuclear Station identified a potential missed surveillance
of the Spent Fuel Storage Canister Heat Removal System Surveillance Requirement (SR) 3.1.2.

This is a surveillance requirement in the Holtec CoC No. 1032 Amendment 0, Revision 1 for the HI-STORM FW.
It was identified that the station suspended verifying all overpack inlets and outlets were free of blockage from solid debris
or floodwater every 24 hours and began utilizing the alternate surveillance method of installed temperature monitoring equipment.

However, this monitoring equipment had not been declared operable from the completion of the Dry Cask Storage Campaign on April 11, 2019.

 This surveillance was last performed satisfactorily on May 15, 2019.

"The station has documented this missed surveillance in the Corrective Action Program under CR-19-01866.

"The NRC Senior Resident has been notified."

The licensee stated that the temperature monitoring equipment while not operable, was functional.
The licensee successfully performed the surveillance requirement on 5/21/2019.



* * * RETRACTION FROM BETH DALICK TO RODNEY CLAGG AT 0828 EDT ON 6/6/19 * * *

"ENS Event Number 54075, made on May 21, 2019, is being retracted.

"NRC Notification 54075 was made to ensure the 24-Hour Non-Emergency reporting requirement of 10 CFR 72.75(d)(1)(i)
was met for a potential missed surveillance of the Spent Fuel Storage Canister Heat Removal System Surveillance Requirement (SR) 3.1.2.

"On June 4, 2019, a Past Operability Evaluation determined the temperature monitoring equipment,
utilized to complete the Technical Specification Surveillance 3.1.2,
was operable during the time period of 5/16/2019-5/21/2019.

The station performed satisfactory calibration checks on the temperature monitoring equipment
and had not experienced any significant weather events capable of producing vent blockage
(i.e. flood, tornado, snow storm, etc.).

Therefore, utilizing the installed temperature monitoring equipment is not considered a missed surveillance of SR 3.1.2
and renders this event not reportable under 10 CFR 72.75(d)(1)(i).

"VCSNS's evaluation of this event is documented in the Corrective Action Program in Condition Report (CR-19-01866).

"The licensee has notified the NRC Resident Inspector."

Notified R2DO (Rose) and NMSS Events Notification (email).
