REQUEST FOR ADDITIONAL INFORMATION RAI RV-01-1:
Please describe how NPPD is meeting the requirements of ISTC-3530, Valve Obturator Movement, ISTC-5151, Solenoid-Operated Valves (SOVs) - Valve Stroke Testing, ISTC-5152, SOVs - Stroke Test Acceptance Criteria,, and ISTC-5153, SOVs - Stroke Test Corrective Action, at CNS. Please state if NPPD also needs relief from these requirements based on this request.
RAI RV-01-2:
For this relief request, NPPD requested relief from ISTC-3510, Exercising Test Frequency.
NPPD states in the August 24, 2011 request that they will exercise each valve to the full closed position on a quarterly basis, which is equivalent to the nominally every 3 month requirement of ISTC-3510. Please describe in greater detail why NPPD requests relief from ISTC-3510 since it appears that NPPD can meet the requirement.
RAI RV-01-3:
Please provide any additional operational history for valves similar to HPCI-SOV-SSV64 and HPCI-SOV-SSV87 at CNS that can demonstrate greater reliability of these valves for time periods longer than the four maintenance cycles stated in this request.
RAI RV-01-4:
Please identify the consequences of HPCI-SOV-SSV64 and HPCI-SOV-SSV87 failure during normal and emergency operations.
RAI RV-01-5:
Please provide an explanation, as to why the HPCI risk information provided in the August 24, 2011 submittal supports the requested relief.
