| The licensee reported that a computer system upgrade performed on 10/26/01 |
| rendered the SPDS (safety parameter display system) inaccessible from the |
| EOF. The condition was discovered on 10/29/01. The condition has since been |

| "On Oct. 29, 2001 Vermont Yankee reported to the NRC, via Event Number |
| 38436, the loss of the EOF SPDS computers since Oct. 25, 2001. Preliminary |
| investigation identified the loss of the computers was due to an upgrade to |
| the company's computer network performed on Oct. 25. Further investigation |
| on Oct. 30 revealed the EOF SPDS was only unavailable for approximately 3 |
| hours while the actual upgrade was being performed. This notification serves |

| BOTH REACTOR BUILDING TO TORUS VACUUM BREAKERS WERE PREVENTED FROM
|
| RESPONDING TO A REACTOR BUILDING TO TORUS DIFFERENTIAL PRESSURE
|
| |
| At 0325 CST, it was identified that the switches for TORUS VACUUM RELIEF |
| valves PC-AOV-243AV and PC-AOV-244AV were in the closed position. With the |
| switches in the closed position, the valves would not respond to a |
| differential pressure between the Reactor Building and Torus as required by |
| SR 3.6.1.7.3. The switches had been placed in the closed position for |
| performance of LLRT on penetration X-205. The valves were declared |
| inoperable and LCO 3.6.1.7 Condition D was entered. The required action for |
| this condition is to restore all vacuum breakers in one line to operable |
| status within 1 hour. If the valves are not restored to operable, Action E |
| is entered, which requires the plant to be in Mode 3 in 12 hours and Mode 4 |
| in 36 hours. The valve switches had been placed in this position as part of |
| a clearance order issued at 2357. |
| |
| At 0342 CST, the switches for the Torus Vacuum Relief valves were returned |
| to the Auto position, and the valves were declared operable as vacuum |
| breakers. The LCO 3.6.1.7 Condition D was exited. |
| |
| The function of the Reactor building to Torus vacuum breakers is to relieve |
| vacuum when primary containment depressurizes below Reactor Building |
| pressure. With the switches in the closed position, the valves would not |
| respond to a situation where a significant negative pressure existed between |
| the Reactor Building and Torus. A negative differential pressure is caused |
| by rapid depressurization of the drywell. Events that cause this rapid |
| depressurization are cooling cycles, primary containment spray actuation, |
| and steam condensation in the event of a primary system rupture. The |
| Reactor building to Torus vacuum breakers prevent an excessive negative |
| differential pressure across the primary containment boundary. |
| |
| This event was determined to be reportable on 11-2-01 at 0430 CST after |
| review of NUREG 1022 and design basis information. |
| |
| The NRC Resident Inspector was notified. |
