The design change was removed from the division one diesel and it was declared available at 2045 on 4/7/05. All three diesels remain inoperable." Perry 1 is currently shutdown in refueling mode 5 and no core alterations are in progress. The licensee will notify the NRC Resident Inspector. * * * RETRACTION FROM KEN MEADE TO PETE SNYDER AT 0852 EDT ON 4/24/05 * * * "Update to Event Notification (ENF 41575) Retraction: "An 8-hour notification was made on April 7, 2005 under 10CFR50.72(b)(3)(v) for the loss of the safety function. The report was made due to declaring division 1 diesel generator inoperable at 2028 hours on April 7, 2005 with Division 2 and 3 inoperable for unrelated refuel outage activities. Division 1 diesel generator was declared inoperable as a result of performing an at-risk design change on the exhaust system, i.e., installing insulation blankets on the exhaust piping. The at-risk design change was removed from the division one diesel generator by 2045 hours on April 7, 2005. No other actions were taken during the course of events that would have otherwise rendered the Division 1 diesel generator inoperable. "An evaluation was completed on April 8, 2005 confirming that the additional weight of the insulation on the exhaust piping had no impact on diesel generator operability. Division 1 diesel generator was subsequently declared operable at 0534 hours on April 9, 2005. "Since there was no loss of safety function, there is no reportable condition. Since there was no reportable condition. ENF 41575 is retracted." The licensee has notified the NRC Resident Inspector. Headquarters Operations Officer notified R3DO (Hills). | General Information or Other | Event Number: 41613 | Rep Org: CALIFORNIA RADIATION CONTROL PRGM Licensee: CALIFORNIA STATE POLYTECHNIC UNIVERSITY Region: 4 City: POMONA State: CA County: License #: 0496-19 Agreement: Y Docket: NRC Notified By: DAVID LITTLE HQ OPS Officer: MIKE RIPLEY | Notification Date: 04/19/2005 Notification Time: 16:11 [ET] Event Date: 01/04/2005 Event Time: [PST] Last Update Date: 04/19/2005 | Emergency Class: NON EMERGENCY 10 CFR Section: AGREEMENT STATE | Person (Organization): MICHAEL SHANNON (R4) MICHELE BURGESS (NMSS) TAS (EMAIL) () | Event Text CALIFORNIA AGREEMENT STATE REPORT - MISSING TRITIUM EXIT SIGNS The following information was provided by the State via facsimile: "[The University] reported the loss of six generally licensed tritium exit signs.

The agreement state licensee, Burcaw Geotechnical Group, was using the gauge at a site located in Ruskin, Florida. The gauge overpack, which was thought to contain the gauge, was picked up at the end of the work day and placed into a truck. While in transit, the driver realized that he had not been verified the gauge was actually in the overpack. He checked the overpack and found it to be empty. He returned to the job site and conducted a search but could not locate the gauge. The licensee informed the Florida Bureau of Radiation Control. The Bureau of Radiation Control requested the licensee to contact the police and report the gauge missing. The Troxler gauge (serial #34752) contained a 40 milliCurie Am-241/Be source and a 10 milliCurie Cs-137 source. | Fuel Cycle Facility | Event Number: 41623 | Facility: PORTSMOUTH GASEOUS DIFFUSION PLANT RX Type: URANIUM ENRICHMENT FACILITY Comments: 2 DEMOCRACY CENTER 6903 ROCKLEDGE DRIVE BETHESDA, MD 20817 (301)564-3200 Region: 2 City: PIKETON State: OH County: PIKE License #: GDP-2 Agreement: Y Docket: 0707002 NRC Notified By: ERIC SPAETH HQ OPS Officer: PETE SNYDER | Notification Date: 04/22/2005 Notification Time: 10:55 [ET] Event Date: 04/21/2005 Event Time: 20:13 [EST] Last Update Date: 04/22/2005 | Emergency Class: NON EMERGENCY 10 CFR Section: OTHER UNSPEC REQMNT | Person (Organization): CAUDLE JULIAN (R2) RICH CORREIA (NMSS) | Event Text AUTOCLAVE SHUTDOWN DUE TO HIGH CONDENSATE "On 04/21/05 at 2013 hours, Autoclave #2 in the X-343 Facility experienced a Steam Shutdown due to high condensate level alarms (A) and (B) actuating.

If through subsequent reviews of this event, additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up will be made via the ENS or under the reporting requirements of 10CFR50.73. "On April 23, 2005, at approximately 11:35 Mountain Standard Time (MST) engineering personnel performing preplanned in-service examinations of reactor vessel head vent penetration in accordance with procedure requirements discovered two axial indications in the Palo Verde Nuclear Generating Station Unit 2 reactor vessel head vent penetration. The indications are located on the inner diameter surface of the pipe adjacent to the J-weld to the head and are part of the RCS pressure boundary. The indications are characterized as axial, estimated less than 0.080 inch deep, approximately 0.1 inch long, and oriented at approximately 90 degrees from each other. The indications are not through-wall. There is no evidence of RCS pressure boundary leakage. "Technical Specifications (TS) Limiting Condition for Operation (LCO) 3.4.14 permits no reactor coolant system (RCS) pressure boundary leakage and there is no evidence of pressure boundary leakage. Nevertheless, the indications are being conservatively identified as abnormal degradation of the reactor coolant system pressure boundary and will necessitate taking corrective action to restore the barrier's capability. Therefore, the ENS notification of this event is in accordance with 10CFR50.72(b)(3)(ii)(A). The Unit had been shutdown for its 12th refueling outage and was being maintained de-fueled for maintenance. "No ESF actuations occurred and none were required. There were no structures, systems, or components that were inoperable at the time of discovery that contributed to this condition. There were no failures that rendered a train of a safety system inoperable and no failures of components with multiple functions were involved. The event did not result in the release of radioactivity to the environment and did not adversely affect the safe operation of the plant or health and safety of the public. " An investigation of this event will be conducted in accordance with PVNGS corrective action program." The NRC Resident Inspector was notified of this event by the licensee. | Power Reactor | Event Number: 41631 | Facility: SUSQUEHANNA Region: 1 State: PA Unit: [1] [ ] [ ] RX Type: [1] GE-4,[2] GE-4 NRC Notified By: RON FRY HQ OPS Officer: CHAUNCEY GOULD | Notification Date: 04/24/2005 Notification Time: 21:39 [ET] Event Date: 04/24/2005 Event Time: 21:30 [EST] Last Update Date: 04/24/2005 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(3)(xiii) - LOSS COMM/ASMT/RESPONSE | Person (Organization): DAVID SILK (R1) MOHAMED SHANBAKY (R1) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 1 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text SPDS (SAFETY PARAMETER DISPLAY SYSTEM) IS DOWN FOR PLANNED MAINTENANCE "At 2130 hours on 04/24/2005 the Unit 1 SPDS system will be removed from service for planned maintenance (cable rework). The duration of work is expected to be 32 hours (scheduled for completion at 0530 hours on 04/26/2005). "ERDS will remain operable during the work window but several points will not be available. For example 23 of 58 ERDS points will be unavailable while SPDS is out of service. However, the ERDS system will still be operable and transmit the remaining points. "Loss of Emergency Assessment Capability - A review of the ability of the Emergency organization to function without SPDS was performed. Alternate sources for many of the points in SPDS were identified and are contained on an Emergency Plan format in PICSY (plant integrated computer system). Those points not available from PICSY can be obtained from the control room. With these compensatory actions and the communications in place between the facilities, there will not be a major loss of emergency assessment capability. "Since the Unit 1-SPDS computer system will be unavailable for greater than 8 hours, this is considered a Loss of Emergency Assessment Capability and reportable under 10CFR50.72(b)(3)(xiii)." The NRC Resident Inspector was notified. | |
