Chairman Palladino Connissioner Gilinsky Connissioner Roberts Coanissioner Asselstine Connissioner Bernthal FROM:
Darrell G. Eisenhut, Director Division of Licensing
SUBJECT:
BOARD NOTIFICATION REGARDING WESTINGHOUSE REACTOR COOLANT PUMP SEALS (BN-84-076)
In accordince with the procedures for board notification, the following information is being transmitted directly to the Commission. The appropriate boards are being notified by copy of this memorandum. This information is applicable to Diablo Canyon, Callaway and Indian Point 2/3 which are currently before the Conmission.
This recent information updates the information provided in BN-83-139 and Atomic Energy Canada Limited test results that may indicate a potential for Reactor Coolant Pump Seal failure under loss of cooling conditions. As stated in BN-83-139 this issue may ultimately raise a new safety concern and is therefore being forwarded for your information.
However, the staff recognizes that the conditions of the test represent events which are currently beyond the designed basis.

APR 0 6 1984 MEMORANDUM F0R:~DavveMMMME$6hNTfffE40C Division of Engineering FROM:
Richard H. Vollmer, Director Division of Engineering
SUBJECT:
BOARD NOTIFICATION REGARDING WESTINGHOUSE REACTOR COOLANT PUMP SEALS
Reference:
Memo from D. Eisenhut to the Commission, dated September 21, 1983, Board Notification Regarding Westinghouse Reactor Coolant Pump Seals (BN-83-139)
As part of the confirmatory research programs related to equipment quali-fication, RES is conducting scale model tests at Atomic Energy Canada, Limited (AECL) of secondary seals (0-rings and channel seals) which are an integral part of the seals of some reactor coolant pumps (RCP).
These tests simulate the conditions which RCP seals would be subjected to during station blackout.
Preliminary indications from AECL indicate failure to seal in some small size 0-ring tests for a range of test conditions which is both more and less severe than the conditions established by Westinghouse for its pumps.
The tests are continuing in order to verify the behavior and complete the planned test program.
These scaled 0-ring and channel seal tests are to be conducted over a -ange of pressures, temperatures, and gap sizes which will bracket the conditions established by Westinghouse for its pumps.
Westinghouse is in the process of submitting an analysis to the staff which establishes lower pressure differentials and somewhat lower temperature conditions for the 0-rings and channel seals.
This analysis is subject to staff review.
A contractor has also been selected to do an independent verification review of the Westinghouse calculations.
Although the tests arc still in progress at AECL and the results are to be considered preliminary at this time, we recommend board notification of this additional information as it relates to the previous referenced board notification.
