ATTACHMENT 1 (Continued) i DISTRICT RESPONSE TO NRC INSPECTION 87-16 NOTICE OF VIOLATIOff The need for a comprehensive Inservice Testing Program update has been recognized and an updated program was drafted in June 1987. The plans for the submission and review of the updated program is discussed in section 4) of this response.
The first section of this violation (87-16-01) concerned the fact that the actual stroke times for the Turbine Throttle Stop Valves TV-1 through TV-04 had not been measured, documented or evaluated.
As mentioned by the inspector in this Inspection Report (87.-16),
Surveillance Procedure SP.213.03C " Turbine Throttle Stop Valve Fail Safe Test" provides for full stroke testing of the valves. While the requirement to " measure" valve closure times was not specifically met, SP.213.03C as well as other surveillance procedures demonstrated the functioning of the valves under varying conditions and provided a high level of confidence that the valves woula have performed their safety function during the period following September 1984.
Similarily, the second section of this violation concerning the failure to full stroke test the Reactor Coolant Pump Seal Injection Valves SIM-019 through SIM-022 (check valves) resulted from not meeting the correct valve testing requirements of the September 25, 1984, NRC letter. However, Surveillance Procedure SP.205.02 " Local Leak Rate Testing" did test these valves in the closed position and provided a high level of confidence that the valves would have performed their safety function.
A discussion of the proposed future testing for both the Turbine Throttle Stop Valves and the Seal Injection Makeup Valves is included in the proposed Inservice Testing Program Plan. This plan is described in section 4) of this response.
j
- 4) The corrective steps that will be taken to avoid further violations:
As a result of the findings of NRC Inspection Report 87-16, a third revision of LER 86-21 will be prepared and submitted to the NRC in order to address and document concerns regarding the safety related I
valves identified in the report.
As a result of the specific problems identified in LERs 86-21 and its 1
revisions and the Notice of Violation 87-16, the District recognized i
the need to perform a comprehensive review and then to update the Inservice Testing Program. A draft of the Inservice Testing Program l
Update was completed in June of 1987, and was in final management l
review as of June 23, 1987.
