March 2007 A. Preservice testing program Per ASME OM Code, Subsection ISTA-2000, defines the preservice test period as the period of time following the completion of construction activities related to the component and before first electrical generation by nuclear heat. B. IST program Per ASME OM Code, Subsection ISTA-2000, prior to first electrical generation by nuclear heat C. Inservice inspection program related to dynamic restraints Per ASME Code, Section XI, IWA-2430(b), before placement of the plant into commercial service D. MOV program Per ASME OM, Subsection ISTA-2000, prior to first electrical generation by nuclear heat Technical Rationale The technical rationale for application of this guidance and/or SRP acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. 10 CFR 50.55a and GDC 1 require, in part, that SSCs which include pumps, valves, and dynamic restraints important to safety be designed, fabricated, erected, constructed and inspected to quality standards commensurate with the importance of the safety functions to be performed. The provisions for functional design and IST programs for pumps, valves, and dynamic restraints in this SRP section are based on sound engineering principles as well as operating experience at nuclear power plants. Meeting the requirements of 10 CFR 50.55a and GDC 1 provides assurance that pumps, valves, and dynamic restraints important to safety are capable of performing their intended safety functions. 2. GDC 2 requires, in part, that components important to safety be designed to withstand the effects of severe natural phenomena, combined with appropriate effects of normal and accident conditions, without a loss of capability to perform their safety functions. Meeting the requirements of GDC 2 provides assurance that pumps, valves, and dynamic restraints important to safety are capable of withstanding the effects of severe natural phenomena while performing their
