Dear Mr. Dewease:
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION - REACTOR COOLANT PUMP TRIP As a result of Combustion Engineering revisions to the approved topical reports CEN-268 and CEN-268 Supplement 1, we have determined that additional information is needed for us to complete our review of TMI Action Item II.K.3.5.
Please advice this office of your schedule for a submittal.
The reporting and/or recordkeeping requirements contained in this letter affect fewer than ten respondents; therefore, OMB clearance is not required under P.L.96-511.
Sincerely,
/s/

1 ENCLOSURE ADDITIONAL-QUESTIONS WATERFORD UNIT 3 DOCKET NO. 50-382 RESPONSE TO GENERIC LETTER 86-06 "IMPLEMENTATION OF THI ACTION ITEM II.K.3.5" REFERENIES:
Letter from K. W. Cook, Louisiana Power and Light (LPL), to USNRC, Letter Number W3P86-2829, February 5, 1987.
2.
Generic Letter 86-06, "Implementation of TMI Action Item II.K.3.5,"
May 29, 1986.
3.
Combustion Engineering Report CEN-268, "Justification of Trip-Two/ Leave-Two Reactor Coolant Pump Trip Strategy During Transients," March 1984.
QUESTIONS:
1.
In CEN-268, Rev. 1, the CEOG stated that containment isolation could cause the loss of pump cooling water and that continued operation under these conditions could result in reactor coolant pump (RCP) damage. Timely operator action could restore water.
service and prevent pump damage. Each utility was to review its plant specific pump cooling service systems requirements and make any changes necessary. On April 23, 1985, the licensees with CE plants were sent a request for additional infomation on this area.
In Generic Letter 86-06, the staff stated that the response to this request for infomation was not available for Waterford Unit 3 and that the review of this item would be completed as part of the plant specific implementation SE review. The submittals for Waterford 3 have not addressed this issue. Therefore, provide the following information.
Identify the systems which are essential for the continued operation of the reactor coolant pumps. Does any containment isolation signal or any other signal (such as SIAS) result in the termination of these systems that are essential for the continued operation of the RCPs? Identify the signals and the systems affected during a containment isolation.
2.
If essential RCP cooling water services are teminated, provide a description of the operator guidelines, training, and procedures in place which assure that these services are restored in a timely manner to prevent seal damage or failure, once a non-LOCA condition has been confimed.
T'.
I a.
Identify the components required to trip the pumps.
Include the relays, power supplies, breakers or other equipment.
Address reliability, alternate trip methods, and operator training. How much time is the operator allowed to trip the RCPs from within the control room befc; 7 using an alternate.
method? How much tir.e is the operator allowed to travel to an alternate location to trip the pumps?
b.
If necessary, as the result of the location of any critical component, include the effects of adverse conditions inside or outside containment on RCP trip reliability. Describe the basis for the adverse conditions selected.
