A surveillance test was being performed on the Emergency Recirc vent System and all six dampers on both trains failed to stroke in the required Tech. Spec. times. Therefore, both trains of the Emergency Recirc Vent System were declared inoperable and the plant entered T.S. 3.0.3. The LCO action statement requires the plant to be in mode 2 in 7 hours and mode 3 in the following six hours and mode 4 in the following 24 hours. They are currently troubleshooting the problem.
The NRC resident Inspector was notified

"Update to [Event] Notifications 41084 and 41085:
At 1840 [EDT] on 10/02/04 it was determined that the apparent slow response times of the Control Room Emergency Recirculation [CRER] dampers was due to a malfunctioning relay in the initiation circuit, not due to failure of the dampers. The LCO actions associated with the CRER system were exited and the actions associated with the initiation instrument were entered. Therefore the plant is no longer required to shutdown per T.S. 3.0.3. The plant shutdown has been terminated. Plant power will be returned to 100%."
The licensee has notified the NRC resident Inspector.

* * * RETRACTION FROM KEN MEADE TO BILL HUFFMAN ON 10/25/04 AT 1433 EDT * * *
"At 1300 on 10/02/04, results of a surveillance indicated that dampers in both trains of the Control Room Emergency Recirculation System (CRERS) were slower than allowed by Technical Specifications (TS) requiring both trains of the CRERS to be declared inoperable. With both trains inoperable, Technical Specification 3.0.3 was entered which required a plant shutdown. The shutdown was commenced at 1500. This condition was reported as required in Event Notification 41085. Additionally, with both CRERS trains inoperable, this condition was determined to be reportable as a loss of safety function (accident mitigation) and was reported as required in Event Notification 41084.
"Subsequently, it was determined that the failure was the result of a defective time delay relay in the radiation monitor initiation circuit. Other inputs that would have caused the dampers to reposition in an accident were not impacted. The appropriate TS (3.3.7.1), for the radiation monitor, was entered and TS 3.0.3 was exited. The significant actions required by this TS were to restore the function within 7 days or place the system in emergency recirculation. It did not require entry into an action to shutdown. When this condition was identified, TS 3.0.3 was exited, the shutdown was terminated, and the plant was restored to full power. Since a TS required shutdown was not required, Event Notification 41085 is being retracted.
"The condition was also reported as a loss of safety function for the accident mitigation function of CRERS. The CRERS is automatically activated by a Loss of Coolant Accident (LOCA) signal or a Control Room Ventilation (CRV) high radiation signal. The LOCA instrumentation circuitry was not affected by the defective time delay relay and thus the damper stroke times were not impacted. The CRV airborne radiation monitor signal is considered a "diverse" signal to the LOCA signal. Since the LOCA signal would have properly initiated the CRERS and the CRV high radiation signal is redundant, there was no loss of safety function. Since there was no loss of safety function, Event Notification 41084 is being retracted."
The licensee has notified the NRC Resident Inspector. NRC R3DO(Gardner) has been notified. |

At 1500 hours the plant commenced reactor shutdown from 100% power for entering T.S. 3.0.3 due to both trains of the Emergency Recirc Vent System being declared inoperable. The reactor will be in mode 2 by 2000 hours, mode 3 by 0200 hours on 10/03 and mode 4 by 0200 hours on 10/04. If the problem is corrected, they will terminate the shutdown.

"On October 18, the licensee called the Division [Tennessee Division of Radiological Health] to report that a shipment brokered by Duratek from their facility in Memphis, TN on September 29 arrived at Laguna Verde Power Station near Veracruz, Mexico on October 5 with three boxes exceeding the removable contamination limits of 49CFR173.443. The boxes contained contaminated equipment, to be used at the Power Station during an outage. The equipment was contaminated with mixed fission/activation products. There was no contamination found on the truck. The boxes were decontaminated onsite."

"This event was reported on 10/19/04 as exceeding the removable contamination limits of 49 CFR 173.443. The licensee has investigated the incident which involved three boxes of GE Nuclear equipment shipped from the licensee to Laguna Verde Nuclear Plant in Mexico. The investigation has shown that this shipment did not violate applicable regulations for international shipments of radioactive materials and most likely did not violate the limits for shipments under the US DOT regulations. The latter statement is qualified. Because the data from Laguna Verde is not sufficient to make any other determination. The area averaging and the smear removal efficiencies were not determined. The investigation has revealed that the shipment violated Laguna Verde's acceptance procedures for loose contamination."

"Well: Mako Steward A-37 State Tract #1, Galveston, County, Texas
9,150 ft. downhole (bottom of well)
"Well logging string became stuck in a 6 3/4" wellbore over the weekend. Attempts to 'fish' for the sources was unsuccessful with the fishing tool becoming stuck in the wellbore above the well logging tool string. The tool string contains three sealed sources: an 18 curie Am-241/Be; a 2 curie Cs-137; and a 0.8 microcurie Cs137. The sources were declared abandoned late on October 19, 2004. The Licensee is preparing to seal the well with red dyed cement and placement of a deflection device in the wellbore. The tool string is sitting at the bottom of the well at 9,150 feet downhole. Source manufacturers and serial numbers are currently unavailable."

| Event Text TROXLER GAUGE STOLEN FROM THE BACK OF A PICKUP TRUCK
An employee of Foundation Engineering Science, Newport News, Virginia, checked out a Troxler Model number 3430 moisture density gauge to be used on a worksite located in Norfolk, Virginia. The individual stopped off at Wal-Mart in Norfolk, Virginia, and went inside to get some items. When he arrived back he found the Troxler moisture density gauge missing. He went back into Wal-Mart and viewed a video tape taken by the Wal-Mart security camera. Two individuals in a truck were seen taking the gauge. Norfolk police were contacted and a police report was made (did not have police report number). It is unknown at this time if the gauge was chained and locked to the bed of the pickup truck (company policy is to chain and lock the gauge to the bed of the pickup truck). The Troxler moisture density gauge stolen model number is 3430 and its serial number is 29129. This information was relayed to Troxler and they have entered this information into their data base. The gentleman making the report did not know if a reward had been announced for the recovery of the gauge. Troxler Model 3430 source strengths are typically (8 millicuries of cesium-137 and 40 millicuries of Am-241/Be). | |
