"The gauge was discovered in Las Vegas on October 8, 2004, apparently left at a job site. The man who found the gauge recognized what it was from past work experience. The gauge was stored at a fire station until it could be picked up by the owner. The gauge was not in a case but appeared OK and the shutter was closed. The owner confirmed pickup of the gauge on October 12, 2004."

"At 0741 [EDT], an unplanned actuation of an ESF system occurred due to the unplanned start and loading of the 'A' Emergency Diesel Generator (EDG). The plant was in a refueling outage in Mode 5 with the Reactor Coolant System (RCS) depressurized. The 'B' Emergency Safety Bus was operable and protected. The 'A' EDG started when the feeder breaker to the 'A' train Emergency Safety Bus opened unexpectedly, de-energizing the bus. The 'A' Emergency Diesel Generator (EDG) started and re-energized the bus as designed, and the 'A' Safeguard Sequencer initiated loading of the bus. Two anomalies occurred during re-energization of the 'A' emergency bus loads. Bus 1A3-SA, which provides power to various safety related load centers and supplies support system loads, did not re-energize. Additionally, the 'A' Emergency Service Water (ESW) pump did not start. The cause of the initial bus feeder breaker opening, and the cause of the subsequent equipment failures is under investigation. Bus 1A3-SA was manually re-energized at 1029. The 'A' ESW pump was manually restarted at 1054."
The 'A' EDG cooling water was provided by the service water system which was not affected by the trip. The 'A' RHR pump was in service to provide Shutdown cooling and the pump tripped when the 'A' Train Emergency Safety Bus was deenergized. Reactor plant temperature rose from 116 to 122 degrees F in the four minute period prior to the restart of the 'A' RHR pump. 'A' RHR pump was restarted at 0745, and 'B' RHR pump was started at 0843 as a backup. Shutdown cooling was transferred to the 'B' Shutdown cooling loop at 1343 and the 'A' RHR pump was secured.

"In 1991, four unirradiated nuclear instrumentation (NI) detectors (includes detector, cable, and connector) were identified as being damaged. These four NI detectors were dispositioned by cutting the detectors from the cable and placing these detectors in a small Special Nuclear Material (SNM) container which then had tamper seals applied. The remaining cables and connectors were disposed of as trash. On October 6, 2004, the small SNM container was moved from its normal storage location to another plant location in preparation for disposal and was opened to verify the contents on October 7, 2004. The actual contents of the container were three NI connectors (not detectors) and one NI detector. Therefore, three NI detectors containing SNM were identified as unaccounted for.
"The contents of this SNM container have been periodically inventoried since 1991 verifying that the tamper seals are intact in accordance with the site SNM inventory procedure, and in March 2004, a periodic SNM inventory was performed in accordance with Exelon SNM inventory procedure. As allowed by the Exelon SNM inventory procedure, however, the contents of the small SNM container were not inspected since the tamper seals were intact. A search of the normal NI detector storage location was performed and it was verified that the unaccounted for detectors were not in another container.
"The other NI detectors in the storage area were accounted for by performing a serial number inventory. Only the three NI detectors missing from the small SNM container are unaccounted for. The total mass of U235 in the unaccounted for SNM was much less than one gram. The actual total mass was determined to be approximately 6 milligrams. It has been determined that the U235 activity of the unaccounted for SNM was greater than 10 times the activity listed in 10CFR20, Appendix C. The actual U235 activity was determined to be 0.012 microcuries, which exceeds 10 times the Part 20 Appendix C activity (i.e., 0.010 microcuries). Therefore, this loss of SNM is reportable in accordance with the requirements of 10 CFR 20.2201(a)(1)(ii). Both the NRC Resident and IEMA Resident were notified.
"CPS records are being reviewed to determine the actual disposition of the NI cables that were disposed of in 1991." |

"On 10/18/04 at 1815 EDT, a spill of untreated raw sewage from a damaged sewage pipe from the Site Management Building occurred. The sewage entered a storm drain and was therefore released to the Susquehanna river. SE-6, 'Pollution Incident Protection Procedure', was entered. The quantity of the spill is estimated at less than 200 gallons and the duration was approximately 1 hour. Per SE-6, the following were contacted: National Response Center, PA Department of Environmental Protection Region III, MD Department of the Environment. Downstream users are in the process of being informed of the spill. The storm drain path to the river has been covered, absorbent pads are being used to collect the spillage, and the damaged sewage piping is being temporarily repaired."
