Indian Point Unit 2 entered TS 3.0.3 (TS Required Shutdown) at 0345 EDT on 10/3/11 after declaring all three Containment Recirc Fan Coolers inoperable due to insufficient Service Water (SW) flow through SW Headers 1, 2, and 3 during the quarterly surveillance test. At 0438 EDT, Unit 2 commenced a controlled shutdown. The licensee has shifted SW flow to Headers 4, 5 and 6 and is in the process of re-performing the test. If the test is successful, they will exit TS 3.0.3. Unit 2 is currently stable at 99% reactor power.
The licensee informed state agencies and the NRC Resident Inspector.

"Three trains of Fan Cooler Units (FCU) are inoperable due to insufficient flows during the flow test 2-PT-Q016. Entered ITS 3.0.3 at time 0345 EDT. At time 0438 EDT Unit 2 commenced a plant shutdown. At time 0515 EDT the plant was at 99% and stable under operator control. Service water headers were swapped from the 1,2,3 header to the 4,5,6 header. The plant is in the process of re-performing the FCU flow tests with the 4,5,6 as the essential Service Water header."
The licensee informed the NRC Resident Inspector. Notified R1DO (Doerflein).

"At 0850 [CDT] on Monday, October 03, the Callaway Plant Technical Support Center (TSC) is undergoing planned maintenance to repair MTSUB7001, Manual Transfer Switch between normal and emergency power. This maintenance is currently scheduled to last for 1 day, at which time the TSC will be restored to service. During this period, the TSC will be without either normal or emergency power, thus rendering it non-functional.
"If an emergency is declared requiring TSC activation while the TSC is non-functional, TSC emergency response personnel will report to their backup locations in accordance with Callaway Plant emergency planning procedures.
"This notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii) due to the planned unavailability of an emergency response facility.

"Dual Unit Shutdown due to T.S. 3.0.3. Unit 1 and Unit 2 'A' Train Emergency Diesel Generators (EDGs) OOS [Out-of-Service]. '2A' DG OOS due to '21' Salt Water Header scheduled maintenance. '1A' DG OOS due to emergent loss of '16' Battery charger for the '1A' DG DC bus. Neither '11' nor '22' 125 VDC busses have an Operable charger. (Chargers have power, but do not have an Operable DG). "
The licensee entered TS 3.0.3 at 1035 EDT and is expected to be in Mode 3 on both units at 1735 EDT unless the licensee exits T.S. 3.0.3 upon restoration of the battery charger. '0C' EDG is functional but not credited towards T.S. The salt water header is not expected to be restored until 10/4/11. There are no issues with offsite power.
The NRC Resident Inspector has been notified. The licensee will notify the Calvert Control Center and plans to make a press release.

"At 0400 EDT on Tuesday, October 4, 2011, the Cook Nuclear Plant (CNP) Technical Support Center (TSC) air conditioning and charcoal filtration systems will be removed from service for scheduled maintenance.
"Under certain accident conditions the TSC may become unavailable due to the inability of the air conditioning and charcoal filtration systems to maintain a habitable atmosphere. Compensatory measures exist to relocate TSC personnel to the unaffected unit's control room, if necessary.
"TSC ventilation system maintenance is scheduled to be completed by 1500 EDT on Tuesday, October 4, 2011.
"The licensee has notified the NRC Resident Inspector.
"This notification is being made in accordance with 10 CFR 50.72 (b)(3)(xiii) due to the loss of an emergency response facility." | |
