| UNANALYZED CONDITION |
| |
| "On 8/06/2003 at 1630 hours, the Beaver Valley Power Station (BVPS) Unit 2 |
| control room was notified by Engineering that the manual operator actions |
| specified in Unit 2 post-fire procedures are not adequate for defeating a |
| potential fire-induced spurious operation of the Power Operated Relief |
| Valves (PORVs). The procedure step de-energizes the PORVs by opening |
| breakers at the d-c distribution panel. This action alone would not be |
| sufficient to prevent a cable-to-cable hot short from re-energizing the |
| circuit since the de-energized circuit is routed in cable trays with other |
| energized circuits in the affected fire areas. Preliminary reviews have |
| identified the following potentially affected fire areas: |
| |
| CB-1 Control Building Instrumentation and Relay Area |
| CB-2 Control Building Cable Spreading Room |
| CB-3 Control Building Main Control Room |
| CB-6 Control Building West Communication Room |
| CT-1 Cable Tunnel |
| CV-1 Cable Vault and Rod Control Area |
| SB-1 Emergency Switchgear Room (Orange) |
| RC-1 Reactor Containment |
| |
| "An hourly roving fire watch patrol has been established for the affected |
| fire areas as compensatory measures, with the exception of the Main Control |
| Room and the Reactor Containment area, until the condition is fully |
| evaluated and resolved. The Main Control Room is continuously manned and |
| does not require an hourly fire watch patrol. The Reactor Containment area |
| is not accessible during normal power operations and, as such, compensatory |
| measures for this area will include a once-per-shift verification of remote |
| instrumentation by operations personnel to confirm that there are no |
| abnormal conditions or indications for this area. |
| |
| "This condition was discovered during the review of manual operator actions |
| for fire-induced spurious operations to confirm the safe shutdown circuit |
| analysis is consistent with the manual actions identified in the |
| procedures. |
| |
| "This condition is being reported pursuant to 10 CFR 50.72(b)(3)(ii) as an |
| unanalyzed condition that significantly degraded plant safety since the |
| failure to assure the PORVs remain in the closed position could result in |
| the failure to meet the fire protection safe shutdown criteria. BVPS Unit 2 |
| was licensed to the NUREG 0800 Standard Review Plan 9.5.1 "Fire Protection |
| Program", and License Condition 2.F requires compliance to the provisions of |
| the approved fire protection program as described in the Final Safety |
| Analysis Report. UFSAR Section 9.5A.1.2.1.6 states that the safe shutdown |
| capability should not be adversely affected by a fire in any plant area |
| which results in spurious actuation of the redundant valves in any one |
| high-low pressure interface line. Even though there is a very low |
| likelihood of multiple shorts causing a spurious PORV actuation in an |
| ungrounded DC circuit, the existing actions to prevent re-energizing the |
| circuit and causing a spurious actuation of the PORVs is not consistent with |
| the NRC guidance for high-low pressure interface valves. |
| |
| "The NRC resident inspector has been notified." |

| |
| "On 8/07/03 at 1515, the following additional areas were identified as being |
| potentially affected by this condition: |
| |
| CV-2 Cable vault and Rod Control Area (East) |
| CV-3 Cable vault and Rod Control Area (Elev 755'6") |
| SB-2 Emergency Switchgear Room (Purple) |
| SB-3 Service Bldg. Cable Tray Area |
| ASP Alternative Shutdown Panel Room |
| |
| "Interim compensatory measures in the form of hourly roving watch patrols |
| have been expanded to include the above noted areas until the condition is |
| fully evaluated and resolved. |

| RADIOGRAPHIC EXPOSURE DEVICE FAILURE |
| |
| "Description of the equipment problem. On June 3, 2003, gamma radiography |
| operations using an AEA Technology/QSA Model 660A exposure device in a |
| permanent radiography facility at Shore Intermediate Maintenance Activity |
| were being performed under the authority of Naval Radioactive Materials |
| Permit (NRMP) No. 0465918--A1NP. On the tenth exposure of the day the |
| radiographer attempted to retract the radiographic source into the |
| radiographic exposure device. The radiographer placed the drive cable brake |
| in the "off" position and rapidly cranked the source in the retract |
| direction. The number of turns coming in matched the number of turns going |
| out. The permanent facility gamma alarm shut off, however the radiographer |
| did not hear the locking slide mechanism engage which is normally heard |
| clearly when retracting the source. When attempting to re-expose the source |
| as required by the operating procedure, the source did expose again. The |
| Radiation Safety Officer was present and directed the radiographer to |
| retract the source again. As with the first attempt to retract the source, |
| the slide bar did not click in the safe position. Again and the gamma alarm |
| shut off. The Radiation Safety Officer entered the permanent facility with, |
| an operating survey meter. The locking slide bar indicated green (safe) but |
| it was not locked in that position. The Radiation Safety Officer approached |
| the device and observed a reading of approximately 8 millirem/hour on the |
| front of the device and 10 millirem/hour on the back of the device. She |
| exited the permanent facility and discussed the situation with the |
| radiographer. The Radiation Safety Officer then directed the radiographer |
| to maintain control of the crank assembly handle and she entered the |
| permanent facility with a survey meter and pushed the slide bar to the red |
| (expose) position. The Radiation Safety officer exited the permanent |
| facility and instructed the radiographer to retract the source to the fully |
| locked position. The retraction was successful and the slide bar was heard |
| to click to the fully green (safe) position. The Radiation Safety Officer |
| checked her self-indicating pocket dosimeters which both indicated zero |
| exposure. |
| |
| "The source was transferred to an AEA 650L source changer on June 4, 2003. |
| A "dummy" source was installed in the exposure device and the locking slide |
| bar was placed in various positions to experiment and recreate the scenario. |
| Frequently during these tests, the radiographers were not able to lock the |
| slide into place without unlocking the drive cable crank assembly and |
| applying minimal pressure towards the expose position. This is considered a |
| neutral position and not an exposed position. With minimal pressure the |
| slide bar mechanism easily locked into the exposed position. |
| |
| "Cause of each incident. The cause of the incident appears to be twofold. |
| Primarily the compression springs for the posi-lock may have been |
| excessively worn. Secondarily, the Shore Intermediate Maintenance Activity, |
| San Diego operating procedure did not call for them to unlock the crank |
| assembly cable lock prior to rotating the selector ring to the operate |
| position and pushing the posi-lock slide bar from the green (retracted) |
| position to the red (operate) position as stated in the most recent AEA |
| exposure device manual. We believe that the faulty springs were the main |
| factor as the posi-lock slide bar can be pushed to the red position with the |
| crank assembly cable lock in the "on" position but that procedure may have |
| contributed to the excessive wear on the compression springs. |
| |
| "Name of the manufacturer and model number of equipment involved in the |
| incident. The equipment involved in the incident was manufactured by AEA |
| Technology/QSA and consisted of a Model 660A exposure device, serial number |
| A4450 with a 13.6 curie Ir-192 source. |
| |
| "Place, date and time of the incident. The incident occurred at Shore |
| Intermediate Maintenance Activity, San Diego, California in a permanent |
| facility on June 3, 2003. |
| |
| "Actions taken to establish normal operations. The Radiation Safety Officer |
| entered the permanent facility and manually pushed the locking slide bar to |
| the unlocked (red) position. The Radiation Safety Officer exited the |
| permanent facility and instructed the radiographer to attempt to retract the |
| source. The source was successfully retracted to the fully locked position |
| and the locking slide bar was heard to lock. |
| |
| "Corrective actions taken or planned to prevent recurrence. Shore |
| Intermediate Maintenance Facility, San Diego replaced the compression |
| springs for the posi-lock assembly on the exposure device. Additionally, |
| they have changed their operating procedure to unlock the crank assembly |
| cable lock prior to rotating the selector ring to the operate position and |
| pushing the posi-lock slide bar from the green (retracted) position to the |
| red (operate) position." |
| |
| The licensee notified R2 (Diaz). |
