nce Criteria should specify that each automatic containment isolation valve listed in the ITAAC table travels from the full open to full closed position in less than or equal to the time listed in the applicable ITAAC table after receipt of a containment isolation signal. (iii) An ITAAC should verify the stroke capability of check valves as part of preoperational testing. The Design Commitment should specify that the system’s safety- related check valves will open and close under design- basis temperature, differential pressure and flow conditions. The ITA should specify that stroke tests will be performed of the system’s safety-related check valves under preoperational temperature, differential pressure and flow conditions and that the data obtained from the stroke tests will be analyzed to demonstrate that each valve is capable of performing its safety functions under those conditions. The Acceptance Criteria should specify that each system safety-related check valve listed in the ITAAC table strokes fully open and closed (under forward and reverse flow conditions, respectively) under preoperational temperature, differential pressure, and flow conditions. Analysis, based on sufficient diagnostic data, should demonstrate that each valve will perform at its design-basis capability as established by the type test performed in accordance with the applicable functional qualification ITAAC. (iv) For valves that move to or maintain their safety position upon loss of motive power, an ITAAC should verify this capability for the applicable valves as part of preoperational testing. The Design Commitment should specify that those applicable systems safety-related valves will perform their function to fail to (or maintain) their safety-related position on loss of motive power under 14.3.3−18 Draft Revision 1 – September 2018 design-basis temperature, differential pressure, and flow conditions. The ITA should specify that stroke tests will be performed of these
