1 MEMORANDUM FOR WILLIAM J. DIRCKS l
EXECUTIVE DIRECTOR FOR OPERATIONS
SUBJECT:
SALEM EVENT I would like the staff to provide the following additional information regarding maintenance of the Salem Reactor Trip Breakers:
( 1)~
Did the Task Force interview Mr. Esposito, the Westinghouse field service representative, who disassembled and inspected the breakers in January, 1983?
Did the Task Force review his field reports?
Could I please have a copy of all the reports and the
- results of any such review.
(2)
Why were the Unit 1 breakers inspected when the previous failures were on Unit 2?
(3)
Was the 1B Bypass breaker disassembled and inspected by Mr. Esposito?
(4)
Why weren't all eight breakers at both units inspected by Westinghouse?
(5)
Following the above maintenance on the Unit 1 breakers, what specific operability tests were performed on each breaker after each was reinserted in the breaker cubicle?
(In particular, were the UV coils tested in place by the solid state protection system?)
(6)
For each Unit 1 breaker (including bypass breakers) in place during the February 22 and 25 events, please trace the history of the breaker (or UV coil, if applicable) giving dates, locations, maintenance, and failures since August 19, 1982.
(7)
Was the Unit 2 reactor taken critical prior to investigating the cause for breaker failure on August 20, and January 6, 1983?
(8)
Does the commercial division of Westinghouse use Calio 78A lubricant on non-safety grade UV coils?

Since the UV coils worked without lubrication for nearly 7 years, why does the staff feel that the above lubricant contributed to failure within a month?
