Docket No. 50-271

Vice President, Operations

Vermont Yankee Nuclear Power Corporation

RD 5, Box 169

Ferry Road

Brattleboro, Vermont 05301

Dear Mr. Reid:

SUBJECT:

VERMONT YANKEE INSPECTION 93-21

This refers to the safety inspection conducted by Messrs H. Eichenholz, P. Harris, and

T. Shediosky on September 12 - October 9,1993, at the Vermont Yankee Nuclear Power

Station, Vernon, Vermont. The preliminary results were discussed with Mr. R. Wanczyk at the

conclusion of the inspection. The inspection focused on issues important to public health and

safety, and consisted of performance observations of the conduct of operations and maintenance,

and independent assessment of safety system status and quality records.

Good outage performance was evident in many instances including recovery of the dropped fuel

bundle, testing of the Vernon Tie blackout source, troubleshooting of a ground on the startup

transformer, inspection of the reactor vessel core shroud,'and residual heat removal heat

exchanger repairs.

We are, however, concerned regarding your staff's interpretation - of your Technical

Specifications. Specifically. your justification to voluntarily remove an emergency diesel

-

generator from service during a time when secondary containment integrity was required was

inappropriately based on a Technical Specification requirement associated with core and

containment cooling. Your staff apparently recognized the ambiguity of the applicable Technical

Specification, but relied on past conversations with the NRC (referenced in a July 9,1984

Vermont Yankee letter to the NRC) that addressed this interpretation and failed to implement

your Limiting Condition of Operation Maintenance Guidelines.- We recommend that you

consider a change to your Technical Specifications to clarify the performance of fuel handling

activities with one eme gency diesel generator out of service. This initiative should reduce any

such ambiguity, and place your license more in line with licensed conditions at other boiling

water reactor facilities.
