BOARD NOTIFICATION REGARDING WESTINGHOUSE REACTriR C000."1 PllMP 5EALS (BN-84-123)
In accordance with the pec:9duras for board noti.'i.:4 tion, the foliening infarration is being transmitted di.'ectly to the Commissie:
Tho appropricte boards t re beiag notified by copy cf this memtrandum.
Inis information is coplicable to Diablo Canyor,, rallavay and Indian Point 2/3 which is currently oefore the Commission.
This recent information updates the information provided in BN-84-139 and BN-84-076.
During the April 16-17, 1984 meetings with Eler.tricite DeFrance, the staff obtained information relati.g to reactor coolant pump performance with no seal cooling.
lne French tests showed a rapid ride in seal temperature end leakage flow rate.
The staff is hoping to obtain the actual test tesults.

June 21,1984 MEMORANDUM FOR:
Darrell G. Eisenhut, Director Division of Licensing FROM:
Richard H. Vollmer, Director Division of Engineering
SUBJECT:
BOARD NOTIFICATION RuGARDING INFORMATION RECEIVED FROM FRENCH ON REACTOR COOLANT PUMP SEALS
References:
(1) Memo from D. Eisenhut te the Commission dated September 21, 1983, Board Notification Regarding Westinghouse Reactor Coolant Pump Seals (BN-83-139)
(2) Memo from R. Vollmer to D. Eisenhut, dated April 6,1984, Board Notification Regarding Westinghouse Reactor Coolant Pump Seah During meetings with Electricite De France (EDF) in Paris, France on April 16-17, 1984 the staf f acquired new information relating to reactor coolant pump (RCP) seal behavior as discussed in the memoranda referenced above.
EDF conducted RCP seal tests at the 900 MW pump test loop at Gennevilliers during 1983 which convinced them to backfit their plants to provide an emergency source of cooling to the RCP seals, during station blackout conditions.
The RCP seals tcsted are similar if not identical to the Westinghouse seals used in the United States.
The tests were performed with the ECP seal in a stationary configuration, subjected to full reactor coolant temperatcre and pressure, with no seal cooling.
The tests were terminated after several minutes in order to prevent damage to the pump assembly being tested.
The rapid rise in seal temperature and leakage flow rate observed during the tests convinced the French that the RCP seal cooling should not be interrupted, except for very short periods of time, during emergencies such as station blackouts.
The Gennevilliers test results also showed that with rapid temperature and flos transients the number one stage of the RCP seal would open.
Based on information received from the French and on a recent RES trip report, it is our understanding that the French are providing a steam turbine driven pump to supply ems rgency cooling for the RCP seals in their smaller plants.
In the larger plants they are providing a steam turbine driven generator as a source of emergency power to an existing pump to supply the RCP seal cooling.
In addition, a backup gas turbine generator will be installed at each four unit plant site to provide another level of emergency electrical power for cooling the RCP seals.
