NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 March 22, 1989 Docket Nos.: 50-269, 50-270, 50-287, 50-369, 50-370, 50-413, and 50-414 Mr. H. B. Tucker, Vice President Nuclear Production Department Duke Power Company 422 South Church Street Charlotte, North Carolina 28242
Dear Mr. Tucker:
SUBJECT:
SCHEDULE FOR RESPONSE TO NRC BULLETIN 88-04, OCONEE, MCGUIRE AND CATAWBA NUCLEAR STATIONS (TACS 69944, 69945, 69946, 69934, 69935, 69898, AND 69899)
On May 5, 1988, the NRC staff issued NRC Bulletin 88-04, "Potential Safety-Related Pump Loss."
The bulletin requested the evaluation of all safety-related pumps for 1) pump-to-pump interaction during miniflow operation that could result in dead-heading of one or more of the pumps, and 2) the adequacy of the minimum flow bypass lines with respect to damage resulting from operation and testing in the minimum flow mode. The bulletin also requested that within 60 days of receipt of the bulletin, licensees provide a written response that (a) summarizes the problems and the systems affected, (b) identifies the short-term and long-term modifications to plant operating procedures or hardware that have been or are being implemented to ensure safe plant operations, (c) identifies an appropriate schedule for long-term resolution of this and/or other significant problems that are identified as a result of this bulletin, and (d) provides justification for continued operation particularly with regard to General Design Criterion 35 of Appendix A to Title 10 of the Code of Federal Regulations (10 CFR Part 50), "Emergency Core Cooling" and 10 CFR 50.46, "Acceptance Criteria for Emergency Core Cooling Systems for Light Water Nuclear Power Reactors." Additionally, the staff requested that within 30 days of completion of the long-term resolution actions, that licensees provide a written response describing the actions taken.
Your letter of August 31, 1988 provided an interim response that identified your planned actions, but provided no schedular information beyond your plans to provide information to the manufacturers by June 1, 1989. A status update was provided by your letter of December 1, 1988, indicating that the various manufacturers would respond from six weeks to five months of receipt of your information, and noting your intent to provide further status update by June 30, 1989. This issue and your projected schedule were discussed by telephone conversation on February 7, 1989.

Mr. H. March 22, 1989 I wish to emphasize the high degree of significance associated with the potential loss of safety related pumps due to the two miniflow design concerns addressed by the bulletin. While we have reviewed your justification for continued operation for each pump and find sufficient support for short term operation, we find that continuation of the present limited assurances well into the latter half of 1989 does not appear to be warranted; nor are we satisfied from the limited information provided that this is necessary if sufficient management attention and resources are directed to completion of this effort. I request that your June 30, 1989 response include a detailed identification of all long-term actions necessary to complete the bulletin and a revised schedule reflecting your efforts to expedite completion.
Siicerely, David B. Matthews, Director Project Directorate 11-3 Division of Reactor Projects -
