LICENSEE DECLARED AN UNUSUAL EVENT DUE TO DETECTION OF A FLAMMABLE GAS IN THE GENERAL SERVICES BUILDING
An NOUE was declared at the site at 2327 PDT due to the discovery of flammable gas in the General Services Building (office space) which is attached to the turbine and reactor building. The source and type of gas has not been identified and investigation is ongoing by HAZMAT trained personnel. The highest level of flammability measured is 50% of LEL (Lower Explosive Limit). The building has been evacuated.
The NRC Resident Inspector will be notified and State local and other Gov agencies have been notified.
* * * UPDATE FROM D. FUJIYOSHI TO M. RIPLEY 0527 EDT 06/24/05 * * *
"EAL # 9.3.U.3 - Report or detection of toxic or flammable gases that could enter or have entered within the Protected Area Boundary in amounts that could affect the health of plant personnel or safe plant operation.
"The event has been terminated based on a thorough survey of the building by HAZMAT personnel. The building in question has been determined to be free of any flammable gases.
"Probable source of gas is from a sewage treatment plant. The gas was carried by a stable breeze to the building's air intake. Immediately prior to the event, initial reports of odorous gas from several building occupants was confirmed using portable instrumentation. The highest flammable gas levels were found at a building air intake. Dissipation of gas concentration was accomplished using normal building ventilation."
The NRC Resident Inspector will be notified and State local and other Gov agencies have been notified. Notified R4 DO (R. Bywater), NRR EO (M. Case), IRD Manager (S. Frant), DHS (Ceasar), and FEMA (Sullivan). |

PART 21 NOTIFICATION - CRITICAL POWER DETERMINATION FOR GE14 AND GE12 FUEL WITH ZIRCALOY SPACERS
The following is a portion of a facsimile received on June 24, 2005 from GE Energy, reference - MFN 05-058 Rev 1:
ATTACHMENT 2 - 60-Day interim Report Notification per §21.21(a)(2), and Transfer of Information per §21.21(b)
(i) Name and address of the individual informing the Commission: J. S. Post, Manager, Engineering Quality &Safety Evaluations, GE Energy - Nuclear, 3901 Castle Hayne Road, Wilmington, NC 28401.
(ii) Identification of the facility, the activity, or the basic component supplied for such facility or such activity within the United States, which may fail to comply or contain a defect: The affected and potentially affected plants are identified in Attachment 1. This concern is limited to plants that have fresh or once-burned GE14 or GE12 fuel with Zircaloy spacers. GE12 fuel with Inconel spacers is not affected.
(iii) Identification of the firm constructing the facility or supplying the basic component, which may fail to comply or contain a defect: Global Nuclear Fuel-Americas, LLC, Wilmington, NC.
(iv) Nature of the defect or failure to comply and safety hazard, which could be created by such defect or failure to comply: During review of GE14 ATLAS critical power tests results, it was discovered that springs on the Zircaloy test spacers used in the GE14 and GE12 critical power testing were deformed, possibly during the testing. This resulted in a potentially non-conservative critical power determination for fuel bundle corner pin locations. This non-conservatism potentially impacts the calculated margin to the Operating Limit Minimum Critical Power Ratio (OLMCPR), the Safety Limit MCPR (SLMCPR), the Rod Withdrawal Error (RWE) analysis, and the R-factors used in the on-line 3D core simulator. GE has completed the evaluation of the impact on the critical power determination, and has completed the evaluation of the impact on the R-factors. GE has performed a preliminary evaluation of the impact on the margin to the OLMCPR, the impact on the SLMCPR, and the impact on the RWE event. Potentially affected plants have been informed and have taken appropriate compensatory actions.
(v) The date on which the information of such a potential defect or failure to comply was obtained: This concern was identified in the GE safety evaluation program on April 26, 2005.
(vi) In the case of a basic component which may contain a defect or failure to comply, the number and locations of all such components in use at, supplied for, or being supplied for one or more facilities or activities subject to the regulations in this part: The basic component that may contain a defect is the critical power determination for fresh and once-burned GE14 and GE12 fuel with Zircaloy spacers. GE12 fuel with Inconel spacers and other GNF fuels are not affected. In the US, only GE14 is affected since all GE12 designs in the US have Inconel spacers.
(vii) The corrective action which has been, is being, or will be taken: the name of the individual or organization responsible for the action; and the length of time that has been or will be taken to complete the action (note, these are actions specifically associated with the identified Potential Reportable Condition evaluation): GE has completed the evaluation of the impact on the critical power determination and has completed the evaluation of the impact on the R-factors. GE has performed a preliminary evaluation of the impact on the margin to the OLMCPR, the impact on the SLMCPR, and the impact on the RWE event.
Plants that may have non-conservative process computer calculated OLMCPR margins have taken compensatory action as necessary based on the magnitude of the non-conservatism to prevent inadvertently exceeding the OLMCPR during plant operating maneuvers.
Additional corrective actions planned are as follows:
1. Complete the current-cycle analyses to confirm the non-conservative MFLCPR impact (September 20, 2005).
2. Complete the analysis for previous cycle(s) extending to the previous three years of operation to determine which plants may have a non-conservative MFLCPR (December 15, 2005).
3. Complete the analyses to confirm that no plant has a SLMCPR impact greater than or equal to the reportable threshold of 0.01 (September 20, 2005).
4. Determine and provide the necessary data for plants that perform their own SLMCPR calculations, or that operate with fresh fuel batches of non-GE fuel along with second cycle affected GE14 fuel (September 30, 2005).
5. Complete the evaluation to confirm that the RWE analyses do not impact the OLMCPR (September 20, 2005).
6. Provide bundle R-factor and software updates for the on-line 30 core simulator (beginning in August 2005, and extending through the balance of 2005).
(viii) Any advice related to the potential defect or failure to comply about the facility, activity, or basic component that has been, is being, or will be given to purchasers or licensees: Affected plants should continue to work with their GE Customer Account Leader to obtain information as plant-specific calculations are completed.

NUCLEAR DENSITY GAUGE DAMAGED AT JOBSITE
At approximately 1515 EDT on 6/24/05, a CPN Nuclear Gauge, Model NC1DRP, S/N MD00505618 containing two (2) sources, i.e., 10 millicuries Cs-137 and 50 millicuries Am-241:Be, was run over by a loader at a jobsite near the intersection of Olley Lane and Little River Turnpike in Fairfax County, VA. The area was isolated and rad surveys conducted by the RSO confirmed that the source was not exposed (a radiation level of .4mR/hr was measured at a distance of 1 meter). The RSO will package the damaged gauge and return it to the manufacturer for evaluation. No assistance from any HAZMAT/Fire Department personnel was requested or needed. |

SAFETY PARAMETER DISPLAY SYSTEM FAILURE IN EMERGENCY OPERATIONS FACILITY
"At 1530, on June 24, 2005, Training personnel reported a problem with the Safety Parameter Display System (SPDS) screens at the Emergency Operations Facility (EOF). Subsequent investigation determined that data was being updated, but the SPDS screens would not respond to keyboard or touch screen commands. SPDS was declared inoperable at 1630.
"The SPDS computer system is designed to monitor and display a concise set of parameters from which the safety status of both units can be readily and reliably determined. The system provides plant status information to the Unit-1 and Unit-2 control rooms, the Technical Support Center (TSC), and the Emergency Operating Facility (EOF).
"The controls and displays in the computer room, both Control Rooms and the TSC were unaffected by this condition.
"A bad communications card was found and replaced at the EOF. SPDS operability was restored at 1735."
The licensee notified the NRC Resident Inspector. |

EDG INOPERABLE DUE TO LOOSE ELECTRICAL CONNECTION
"On June 25, 2005, at about 1335 PDT, during a test of Unit 3 Emergency Diesel Generator (EDG) 3G003, Emergency Supply Fan 3A276 did not start. SCE's investigation found a loose electrical connection at the thermal overload auxiliary switch contact for that fan. A similar condition was found on Emergency Supply Fan 3A277. SCE declared 3G003 inoperable and initiated a common cause investigation required by the EDG Technical Specifications. SCE tightened the affected electrical connections and after successfully start testing 3G003, declared 3G003 operable at 0406 PDT on June 26, 2005.
"On June 26, 2005, at about 0417 PDT, SCE found similar loose connections for EDG 3G002. Components affected were the EDG radiator fan and an EDG Emergency Supply Fan. Because SCE could not conclusively determine if the loose connections would have caused 3G002 to be inoperable, SCE conservatively declared 3G002 inoperable. (SCE currently plans to start test the Unit 2 EDGs today to confirm the Unit 2 EDGs remain operable.)
"Because it appears that both Unit 3 EDGs could have been inoperable at the same time, SCE is reporting this occurrence in accordance with 10CFR50.72(b)(3)(v)(D) as an event or condition that could have prevented fulfillment of a safety function.
"At the time of this occurrence, Unit 2 was operating at about 99 percent power and Unit 3 was at about 100 percent power. SCE has notified the NRC Resident Inspectors about this occurrence and will provide them with a copy of this report." |

EMERGENCY DIESEL GENERATORS INOPERABLE DUE TO HIGH AMBIENT TEMPERATURE
"The report is being made in accordance with 10 CFR 50.72(b)(3) due to both Emergency Diesel Generators (EDGs) being declared inoperable. [This is a 24-hour LCO.] The EDGs were declared inoperable due to indicated outside air temperature exceeding the established operability limit of 95F for two short periods of time. Indicated outside air temperature went above 95F during the following time frames: 10:55 to 11:00 and 12:15 to 12:20. Indicated outside air temperature subsequently decreased to less than 95F following these spikes. Both EDGs are currently operable. Outside ambient temperatures are continuing to be monitored. Offsite power is available.
"Further evaluation of this event is ongoing."
