| 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."                                                    |

| "Additionally, on 7/7/2000, another unsealed borehole of 2.75 inches in      |
| diameter was identified in non-safety Switchgear bus 152 (1AP02B) cubicle 4. |
| Both boreholes are located in the floor separating the Unit 1 Division 1     |

| 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.   |
