Dear Sir:
Subj ect: Vermont Yankee Response to Generic Concerns on Purging and Venting Reference (b) requested Vermont Yankee to supply certain information regarding the Staff's concerns on purging and venting.
The information presented below is the first of the two responses requested in Reference (b).
I.
Safety Actuation Signal Override Vermont Yankee agrees to enhance the existing administrative and indicating features by adding equipment which will provide annunciation whenever the High Radiation Signal from either the Reactor Building Vent Exhaust or the Reactor Building Refueling Zone is bypassed. We expect that this effort will be completed before startup from the 1983 refueling outage.
II. Technical Specifications Vermont Yankee has reviewed its existing Technical Specifications against the sample provided as Enclosure (6) to Reference (b). No areas were identified where any expansion of the existing Technical Specification was needed. We would like to point out, however, that any requirement to lock shut BWR containment purge supply and exhaust isolation valves would seem to have a negative safety impact. This is due to the fact that these valves are typically located inside the Reactor Building and may be inaccessible following an' accident, rendering the purge and vent systems inoperable.
We trust the information presented above is acceptalle; however, should you have any questions, please contact us.
Very truly yours, VERMONT YANKEE NUCLEAR POWER CORPORATION 8202180182 820212
