| - 24 hour Report, Violation of Operating License, condition existing longer |
| than permitted by Plant Tech Specs - |
| |
| Carbon samples obtained from Fuel Handling Building Exhaust Filtration Unit |
| Train A failed laboratory tests. The Plant Technical Specification |
| 4.7.8.a.2 limit of less than 1% methyl iodide penetration was exceeded. The |
| as-found methyl iodide penetration results were 1.07%. This resulted in the |
| Train A Fuel Handling Exhaust Filtration Unit being inoperable since the |
| time that the carbon samples were obtained at 0900 CST on 02/17/00. This |
| results in the system being inoperable for longer than 7 days which is a |
| violation of Technical Specification 3.7.8. Action a. The sample results |
| were obtained at 0840 CST on 02/21/00. |
| |
| This notification is being made pursuant to Operating License NPF-76, |
| Section 2.G for operation or condition prohibited by Plant Technical |
| Specifications. |
| |
| The licensee notified the NRC Resident Inspector. |
| |
| * * * UPDATE AT 1604 ON 02/23/00 BY GREG JANAK TO JOLLIFFE * * * |
| |
| Plant Technical Specification Surveillance Requirement 4.7.8 (b) requires |
| that periodic samples be taken from charcoal beds and analyzed within 31 |
| days after removal. These requirements were met and action to declare that |
| train inoperable was taken upon notification of unsatisfactory results. |
| Based on previous practice, a 24-hour report for a violation of the |
| operating license was made to the NRC as a result of this failure. |
| |
| While onsite for an inspection of the Effluents Program, an NRC inspector |
| questioned the reportability of this event. After further investigation |
| into the issue, and input from both Region IV and NRR on this issue, the |
| licensee has determined that this event is not reportable to the NRC as long |
| as the charcoal in question is replaced within the allowed outage time, as |
| specified in the Plant Technical Specifications. Based on the above, the |
| licensee retracted this event. |
| |
| The licensee plans to notify the NRC Resident Inspector. The NRC Operations |
| Officer notified the R4DO Charles Marschall. |

| HIGH DISCHARGE ALARM FOR THE W-2 COMPRESSOR. LEAK TESTING OF THE W-2 |
| COMPRESSOR INDICATE A SEAL FAILURE WITH POTENTIAL FOR URANIUM HEXAFLUORIDE |
| OUT GASSING. |
| |
| At approximately 2347 hours, 02/21/00, operations personnel received a |
| Cascade Automatic Data Processing (CADP) smoke head alarm for Extended Range |
| Product (ERP) W-2 withdrawal station compressor. Operations personnel had |
| responded to a High Discharge Alarm for the W-2 compressor and upon arrival |
| discovered the compressor shutdown and the CADP smoke head in alarm. No |
| smoke was discovered during the investigation of the alarm, however the |
| smoke head is located inside a heated housing not readily accessible to |
| operations personnel. Leak testing of the W-2 compressor indicated a seal |
| failure with potential for uranium hexafluoride outgassing. |
| |
| Operations and engineering personnel are continuing to investigate the cause |
| of the smoke head alarm, but have not provided evidence at this time to |
| invalidate the alarm. PORTS is reporting this alarm as a valid actuation to |
| a "Q" Safety System. |
| |
| There was no loss of hazardous/radioactive material or |
| radioactive/radiological contamination exposure as a result of this event. |
| |
| The NRC Resident Inspector was notified of this event by the certificate |
| holder. |

| - Discovery of unfiltered leak path from Secondary Containment to outside |
| atmosphere via the SBGT System - |
| |
| During Standby Gas Treatment (SBGT) System testing, the pressure in the room |
| containing the SBGT System was found to be at a lower pressure than |
| Secondary Containment (SC). The SBGT System draws a negative pressure on |
| the SC during accident scenarios. The SBGT System room is located outside |
| SC. With the SBGT System room being at a lower pressure than SC, a possible |
| leakage path is created from SC into the SBGT System room, into the SBGT |
| System (downstream of the filters) and out the plant stack. This path |
| bypasses the SBGT System filtering assumed in the offsite dose analysis. |
| This leakage path is small, but is not currently assumed in the accident |
| analysis. |
| |
| The licensee is determining corrective actions and plans to resolve this |
| issue prior to restarting the plant. |
| |
| The licensee notified state and local officials and the NRC Resident |
| Inspector. |

| - Emergency response procedures implemented due to a smoke head alarm and |
| high pressure vent actuation - |
| |
| At approximately 0835 on 02/23/00, Portsmouth operations personnel received |
| a smoke head alarm for extended range product (ERP) compressor W-3 in Area |
| Control Room (ACR)-4. At the same time, another operator in ACR-4 looked at |
| the TV monitor for the ERP compressors and saw a "puff" of smoke around |
| compressor W-3. The plant's "SEE & FLEE" emergency procedures were |
| immediately implemented. The ERP stations' high pressure vent actuated |
| taking the station below atmospheric pressure. Results of all surveys |
| performed during the emergency response were less than minimum detectable |
| activity. At 0949, the emergency response was cancelled. The ERP station |
| was made inoperable to allow for testing of the system by operations and |
| engineering personnel. Portsmouth is reporting this alarm as a valid |
| actuation of a "Q" Safety System. |
| |
| This event is reportable to the NRC as a valid actuation of a "Q" Safety |
| System in accordance with Safety Analysis Report, Section 6.9 (24-HOUR |
| REPORT). |
| |
| There was no loss of hazardous or radioactive material nor radioactive or |
| radiological contamination exposure as result of this event. |
| |
| The NRC Resident Inspector and DOE site representative were notified of this |
| event. |
