This resulted in a valid actuation of the emergency diesel generator. The plant was in Mode 5, depressurized, with reactor coolant system level at approximately the vessel flange level. This resulted in a temporary loss of residual heat removal flow which was restored within approximately seven (7) minutes. Reactor coolant system temperature increased from 113 degrees F to 140 degrees F. Reactor coolant system level and temperature were stabilized at pre-event values. At this time the licensee is preparing to restore off-site power to the 3A Bus and put the emergency diesel generator in standby. The licensee is also investigating the cause of the power loss to the 3A safety related 4KV Bus. The licensee will notify the NRC Resident Inspector.
In response to questions regarding the cause of the loss of the 3A 4KV bus, the following information is provided: The 3C 480 volt Load Center was de-energized for maintenance and was being restored at the time of the event. One of the maintenance activities associated with the 3C Load Center involved replacement of the 480V feeder breaker for the load center. A rotating cam inside the auxiliary switch for the replacement breaker was misaligned. The misaligned cam caused the switch contacts to operate in reverse, such that normally open contacts would be normally closed and vice versa. One of the auxiliary contacts on the 3C Load Center 480V feeder breaker provides input to the A-train Emergency Diesel Generator (EDG) Load Sequencer. With this contact operation reversed (closed vs. open with the breaker open), the Load Sequencer sensed undervoltage on the 3C Load Center, when the 4kV feeder breaker for the load center was closed. The contact being open would normally block the undervoltage signal, until the 480V feeder breaker was closed and the bus was energized. Once the A-train Load Sequencer sensed the undervoltage condition, the 3A 4kV bus was stripped and then re-energized from the 3A EDG. The licensee notified the NRC Resident Inspector.

| ENS 42400 | 9 March 2006 09:20:00 | Turkey Point | NRC Region 2 | Westinghouse PWR 3-Loop | While the Unit 3 Startup Transformer was inoperable for planned maintenance, it was discovered that both the 3A and 3B Emergency Diesel Generators were inoperable. The Emergency Diesel Generators were inoperable due to a configuration that resulted in the Emergency Diesel Generators being in the Droop mode versus the Isochronous mode. This configuration was improperly established when offsite power was supplied to Unit 3 via the Main and Auxiliary Transformers (Backfeed). Upon discovery, jumpers were installed to place both (Unit 3) Emergency Diesel Generators in the proper Isochronous mode correcting this condition at 0615 on March 9, 2006. Unit 4 was identified to be in a condition where one of its required Startup Transformers (from Unit 3) and one of its required Emergency Diesel Generators (from Unit 3) were out of service. Both (Unit 3) Emergency Diesel Generators were restored to an operable condition approximately twenty (20) minutes after discovery. Technical Specification 3.8.1.1 Action c entered due to inoperable Unit 3 Startup Transformer and one inoperable Unit 3 EDG and requires a 4 hour notification report to the NRC. The licensee notified the NRC Resident Inspector.
As reported in Event Notification # 42400, with Unit 4 at 100% power in Mode 1, and the Unit 3 Startup Transformer out of service for planned maintenance, both the 3A and 3B Emergency Diesel Generators were declared inoperable due to a configuration that placed both Emergency Diesel Generators in the droop mode versus the normal isochronous mode. This placed Unit 4 in a Technical Specification Action Statement for one of its required Startup Transformers and one of its required Emergency Diesel Generators being inoperable. This EN# 42400 supplement documents that, although the 3A and 3B Emergency Diesel Generators were declared inoperable, the droop mode condition is bounded within previous analyses that demonstrate that the Emergency Diesel Generators and required electrical loads would operate to satisfactorily perform their safety function at the resulting reduced electrical frequency.

| ENS 43627 | 10 September 2007 14:51:00 | Turkey Point | NRC Region 2 | Westinghouse PWR 3-Loop | On September 7, 2007, a small amount of water was discovered in the environmental qualification boundary of the 3B RCS Tcold thermowell (TE-3-420) during inspection of the thermowell. Subsequent mass spectroscopy analysis conducted at 1228, on September 8, 2007, indicated small levels of lithium, boron, strontium, and bromine indicating that the source of the water intrusion into the thermowell was likely reactor coolant system (RCS) fluid. Turkey Point Unit 3 Technical Specification (TS) Limiting Condition for Operation (LCO) 3.4.6.2.a permits no reactor coolant system pressure boundary leakage. As a result of the chemical analysis and indication of fluid in the thermowell, this condition is being reported to the NRC pursuant to the requirements of 10 CFR 50.72(b)(3)(ii)(A) as a degraded condition. An investigation of the source of the water intrusion into the thermowell is ongoing. Leakage into the TE-3-420 was previously noted during the last refueling outage for Unit 3 in March 2006 and a Short Notice Outage (SNO) conducted in June 2007. Previous inspections and sampling did not indicate the presence of boron or activity levels that were consistent with RCS water. At the time of discovery, Turkey Point Unit 3 was in Operational Mode 6 (Refueling). Turkey Point Unit 3 is presently defueled. This is a late prompt notification. The NRC Resident inspector will be notified. |
| ENS 43641 | 14 September 2007 02:18:00 | Turkey Point | NRC Region 2 | Westinghouse PWR 3-Loop | During an investigation in response to a low megger reading, a small amount of water was discovered in the environmental qualification boundary of the 22B RCS Thot thermowell (TE-3-422B2). Analysis of the water on 9/13/07 at 2304 showed Cesium 137 and 134, and Magnesium 54 indicating that the source of water intrusion into the thermowell was likely reactor coolant system (RCS) fluid. We are continuing the investigation for potential causes of water intrusion other than the Reactor Coolant System. This report is being made based on the previous indication of RCS leakage into 23A, RCS Tcold thermowell (TE-3-420) (see EN #43627 from 09/10/07) and similar discovery in our preliminary investigation. PTN Unit 3 Technical Specifications (TS) Limiting Condition for Operation (LCO) 3.4.6.2.a permits no reactor coolant pressure boundary leakage in Modes 1-4. This report to the NRC is pursuant to the requirements of 10 CFR 50.72 (b)(3)(ii)(A) as a degraded condition. Turkey Point Unit 3 is presently defueled.

| ENS 43803 | 21 November 2007 19:00:00 | Turkey Point | NRC Region 2 | Westinghouse PWR 3-Loop | At approximately 1115 on 11/21/07 it was discovered that the Unit 3 ERDADS long term historian data stream was not updating. This impacted the ability of the ERDS link to transmit valid data. The modem was functional, but did not appear to be receiving data from the ERDADS computers. The long term historian appears to have gone offline at 1441 on 11/12/07. The probable cause of the malfunction appears to be a post installation modification to the system. The ERDS link was restored at 1130 11/21/07 and testing has confirmed it operable. No evidence of tampering has been discovered and this failure affects Unit 3 only. The NRC Resident Inspector will be notified. |
