11/20/2019 Original Commitment
Description:
Verify periodically the design basis capability of the safety related Motor Operated Valves (MOV)s at STP through its commitment to all three phases of the Joint Owners Group (JOG) program on MOV periodic verification and the additional actions described in its submittals.
Revised Commitment
Description:
STP Electric Generating Station (STPEGS) Motor Operated Valve program will be controlled and managed via the implementation of American Society of Mechanical Engineers Operation and Maintenance Code (ASME OM Code) Operation and Maintenance of Nuclear Power Plants mandatory Appendix III Preservice and Inservice Testing of Active Electric Motor Operated Valve Assemblies in Light-Water Reactor Power Plants Justification for change:
STPEGS has implemented the testing requirements as documented in ASME OM Code mandatory Appendix III (formerly OMN-1) via the inservice testing program pump and valve inservice test plan for the third ten-year interval.
NRC regulatory issue summary 2011-13 identifies the application of mandatory Appendix III of the ASME OM code as an acceptable approach for the periodic verification of the design basis capability of safety related MOVs.
Therefore, the change will satisfy the requirements of 10 CFR 50.55a(b)(3)(ii) and the recommendations of Generic Letter 96-05 for the periodic verification of the design-basis capability of safety related MOVs, including the JOG Class D valves.
