Dear Mr. O'Reilly:

On October 5, 1983 your staff was notified that containment spray system (NS) pump 2B recirculation valve 2NS-8 was found locked open rather than locked closed, and therefore NS Train B was considered to have been inoperable since the last time the pump was tested (September 14, 1983). Pursuant to T.S.

3.6.2 which is reportable per T.S. 6.9.1.10(b), Reportable Occurrence Report R0-370/83-53 was to have been submitted by October 19, 1983. At this time evaluation of the incident and preparation of the report are not yet complete.

The report will be submitted by October 26, 1983.

Very truly yours, B. Yijg,j Hal B. Tucker PBN:jfw cc: Document Control Desk Mr. W. T. Orders U. S. Nuclear Regulatory Commission NRC Resident Inspector Washington, D. C.
