Review of Oyster Creek recordings The HOOs reviewed the recordings of Oyster Creek's event report and the subsequent discussions with NRC management. Oyster Creek did not mention that the loading of the #1 EDG was abnormal or that there were any issues with the Isolation Condensers.
Below is a time line and commentary from the event recordings.
0211 - Initial notification made by the licensee. It should be noted that the licensee initially stated, "One EDG is running. No, both EDGs are running and supplying the vital buses." The licensee also stated that the Station Blackout Combustion Turbine was available.
0221 - The licensee briefed NRC management (NRC response mode decision makers) 0221 - After the licensee brief, Sam Collins asked the licensee if "...all plant equipment responded normally to the event." The licensee stated, "There were no unusual responses."
0226 - Dave Lew asked the licensee if any equipment was out of service. The licensee stated that "No equipment out of service and walk downs indicate all equipment is responding normally". He also stated that "the busses are fine with all vital loads picked up by the EDGs."
0228 - After Dave Lew's questions were answered, Sam Collins asked Marc Dapas if he had any questions.
Mr. Dapas again asked the licensee if any equipment was out of service. The licensee stated that "one Recirc pump was out of service prior to the event (long term) with no impact on the event".
0231 - The licensee and decision maker bridge is separated.
Subsequent briefings by the licensee did not indicate any issues with the loading of the EDG or problems with the isolation condenser. Additionally, the licensee faxed a synopsis of the event to the Operations Center at1 954 which stated that "Operator and plant response to this event was as expected," did not include that at 0136, EDG output breaker failed to close, and did not include that at 0210, they declared 'B' IC inoperable due to an indication problem.
If there are any questions please call me or the Operations Center.
