Mr. Donald A. Reid Vice President, Operations Vermont Yankee Nuclear Power Corporation RD 5, Box 169 Ferry Road Brattleboro, Vermont 05301 r
Dear Mr. Reid:
r
SUBJECT:
SERVICE WATER SYSTEM OPERATIONAL PERFORMANCE INSPECTION AT VERMONT YANKEE 1
This letter confirms the dates of November 1 - 5, and November 15 - 19, 1993 for a service water system operational performance inspection (SWSOPI) at Vermont Yankee. A pre-inspection visit by the team leader and some team members is also scheduled during the week of October 18,1993 to gather information requested in the enclosure to this letter.
The primary objectives of this inspection will be to assess the design, operation, maintenance, surveillance, and testing aspects of the service water system at Vermont i
Yankee and to determine whether this system is capable of performing its intended safety i
functions during all plant operating and accident conditions. The team will also evaluate the
.i implementation of the quality assurance and corrective action programs as related to the SWS and your planned and completed actions in response to Generic Letter 89-13, " Service Water System Problems Affecting Safety-Related Equipment".
We request that you make available the information listed in Enclosure I during the pre-inspection visit scheduled for the week of October 18, 1993. Your cooperation with us during this inspection will be appreciated. Should you have any questions regarding the inspection or the information requested, please contact the team leader, Mr. Peter Drysdale at (215) 337-5289 or me at (215) 337-5282.
Sincerely, Jacque P. Durr, Chief Engineering Branch Division of Reactor Safety i
