ation, and differential pressure are required to satisfy the requirements in Subsection ISTB or ISTF, as applicable, of the ASME OM Code as incorporated by reference in 10 CFR 50.55a, unless relief or an alternative is requested and authorized. In IST table notes for each applicable pump, the applicant should provide its justifications for IST frequencies extended to cold shutdowns or refueling outages, and should reference applicable relief and alternative requests. 4. Inservice Testing Program for Valves A. The scope of the IST program for valves is acceptable if it contains all safety-related valves required by 10 CFR 50.55a(f) and the OM Code. The COL applicant for a passive new reactor may address the IST activities for RTNSS valves as part of its IST program or by other acceptable means. B. The valve test procedures, acceptance criteria, and corrective actions are acceptable if the provisions of Subsection ISTC of the OM Code, as incorporated by reference in 10 CFR 50.55a, are met with regard to valve testing. For example, the application should address overall IST provisions, such as determination of reference values and prohibition of preconditioning, conducting preservice testing of each valve as near as practicable to IST conditions, conducting full stroke testing where practicable, and retesting following maintenance. C. The applicant’s table of valves within the scope of the IST program in its FSAR (or referenced in the DC application with appropriate site-specific valves) is acceptable where the valve IST table includes the valve identification number, description and valve function, valve type, valve actuator, ASME Code Class, ASME OM Code Category, Active or Passive Function, Safety Position, Required Tests, and Test Frequency. The valve test parameters and frequencies specified in the IST table are required to satisfy the applicable 3.9.6-19 Revision 4 – March 2017 requirements in Subsection ISTC of the ASME OM Code as incorporated by reference
