"At 0100 on September 8, 2004, while in Mode 3 conducting a Reactor Building walkdown after an unplanned reactor trip during Tropical Storm Frances, Crystal River Unit 3 identified a potential Reactor Coolant System pressure boundary leak located on a weld associated with a pressurizer level sensing line (upstream of reactor coolant isolation valve RCV-75). The cause of the leak is not known at this time, and the leak did not have a significant effect on plant operation. The last unidentified leak rates that were completed prior to the plant shutdown were 0.10 - 0.13 gpm. This defect in the primary coolant system is unacceptable per ASME Section XI. The condition is 8-Hour reportable per 10CFR 50.72 (b)(3)(ii)(A). The plant will be cooled down to Mode 5 and additional inspections and necessary repairs implemented.
Dry boron crystal deposit are on the sensing line upstream of RCV-75 . See similar event reported by Crystal River Unit 3 on 10/04/03 (event # 40222)
The NRC Resident Inspector was notified of this event by the licensee.

"At 0311 on 9/8/04, Crystal River Unit 3 made an 8-Hour ENS notification in accordance with 10CFR50.72 (b)(3)(ii)(A) concerning a potential Reactor Coolant System pressure boundary leak (Event Notification # 41024). The leak was presumed to exist based on the presence of white, crystalline material deposited on the pipe. The material has been sampled and does NOT contain boron. The presumed leak site has been cleaned and visually inspected with no evidence of a defect in the weld joint or pipe. These additional inspections have demonstrated that the material deposited on the pipe does NOT constitute pressure boundary leakage, and therefore EN 41024 is retracted."
The licensee has notified the NRC resident inspector. |

"Salem Unit 2 experienced a Turbine Trip > P-9 which initiated a Reactor Trip. All rods fully inserted. Aux Feedwater auto start initiated on steam generator low-low level. The cause of the turbine trip is Generator Diff [Differential Current] or Loss of Field. Decay heat removal is via the steam dumps to the main condenser. All safety related systems are available and functioned as designed. The 500 KV breaker 2-10 was cleared and tagged prior to the trip. Upon the turbine/reactor trip, the 500KV breakers 1-9 and 9-10 opened as designed. Due to the 2-10, 1-9, 9-10 breakers being opened, the 500 KV transmission line 5037 is de-energized. Two offsite power sources are available and all 3 Emergency Diesel Generators are operable. The 5037 line will be energized following restoration from scheduled maintenance. There were no personnel injuries."
The licensee stated that the NRC resident inspector and the local township were notified. |

At 04:24 EDT, the Control Room Super Particulate Iodine Noble Gas (SPING), Stack Monitoring System, terminal and the associated terminal in the Technical Support Center (TSC) began printing transmit and receive errors. As a result, all SPINGs were declared inoperable and associated Technical Requirements actions entered for alternate sampling. Review by Nuclear Regulatory Affairs and Shift Supervisor considers the occurrence a loss of Emergency Assessment Capability and is therefore reportable under 10 CFR 50.72(b)(3)(xiii).
Licensee is taking samples every 4 hours.

| Event Text MISSOURI DEPT. OF TRANSPORTATION PICKUP TRUCK CARRYING A TROXLER GAUGE WAS INVOLVED IN AN ACCIDENT.
At 0745 CDT a Missouri Department of transportation pickup truck carrying a Troxler model # 3430 moisture density gauge was involved in an accident. The Troxler gauge was within it case locked inside a metal locked box bolted to the bed of the pickup truck. The open bed pickup truck was traveling on Route E, located between Leeton and 23rd highway in Johnson county, when it was side swiped by another vehicle. The pickup truck slid down the side of a hill. The front quarter panel of the truck was damaged and the truck's side mirror was knocked off. The occupants of the pickup truck got out of the truck and went to the back of the truck, opened the locked metal box and observed that the Troxler moisture density gauge was still in its container undamaged. The Troxler gauge contains 0.3 Gigabecquerels (GBq) of cesium-137 and 1.48 Gigabecquerels (GBq) of americium-241/Be. Nobody was injured in the accident. |

| Event Text TWO TRITIUM EXIT SIGNS MISSING
The two signs were discovered missing when an electrical contractor failed to turn over the exit signs to the University's Radiation Safety Officer. The signs were removed during building renovation that started in June. The contractor apparently stored the signs in a box under his desk and the box was removed and believed disposed of as trash. The licensee will follow-up in a written report. | |
