Dear Mr. De1 George:
HCRockhold, EG&G/ Idaho
Subject:
Pump and Valve Inservice Testing Program - La Salle County Station, Units 1 and 2 Enclosed are questions which were developed as a result of the review of your pump and valve inservice testing program. This review was performed by EG&G under a technical assistance contract to NRC. To proceed with this review, we would like to arrange a working meeting at the La Salle site, and the enclosed questions would serve as the agenda for the meeting.
We would like to arrange this meeting for sometime during the week of August 23, 1982.
