| UNIT OUTSIDE DESIGN BASIS DUE TO 10 CFR PART 50, APPENDIX R ISSUE |
| |
| "At approximately 1610 on 7/11/2000, it was identified by plant walkdown |
| that in electrical switchgear Bus 142Y (1AP06B) cubicle 4 (for the Unit 1 B |
| Residual Heat Removal pump) that an unsealed borehole of approximately three |
| (3) inches in diameter existed. This borehole is located in the floor |
| separating the Unit 1 Division 2 Switchgear room from the Unit 1 Division 1 |
| switchgear room. The borehole is located in a three (3) hour rated fire |
| barrier that is required by Administrative Technical Requirement 3/4.7.6 |
| (Fire Rated Assemblies). This has been considered an event that is outside |
| the design basis due to required design basis protective features for safe |
| shutdown trains as described in 10 CFR 50, Appendix R and Final Safety |
| Analysis Report [being] lacking. Compensatory measures (fire watches) have |
| been established per Administrative Technical Specifications and plans for |
| repairs are in progress." |
| |
| The NRC resident inspector has been notified of this event by the licensee. |

| Both boreholes are located in the floor separating the Unit 1 Division 1 |
| switchgear room from the Unit 1 Division 2 Switchgear room. Both boreholes |
| are in a three (3) hour rated fire barrier that is required by |
| Administrative Technical Requirement 3/4.7.6 (Fire Rated Assemblies). This |
| has been considered an event that is outside the design basis due to |
| required design basis protective features for safe shutdown trains as |

| [being] lacking." |

| MISSING MOISTURE/DENSITY GAUGE |
| |
| The licensee reported that a Troxler Model 3411 nuclear moisture/density |
| gauge containing 8 mCi of Cs-137 and 40 mCi of Am-241/Be (S/N 18561) was |
| missing from the Sterling, VA area. A company employee, who resides in West |
| Virginia, was scheduled to bring the gauge to a job site in the northern VA |
| area on 7/11/2000, but failed to show up. Neither the individual, the |
| company vehicle that he was using, nor the gauge can be located. The company |
| last had contact with the employee on 7/7/2000. The licensee did not believe |
| that the individual was a disgruntled employee. The licensee has contacted |
| local law enforcement agencies regarding the missing individual and gauge. |
