1.192. OMN-19 (2022 Edition) Alternative Upper Limit for the Comprehensive Pump Test Applicants or licensees who use this OM Code Case must implement a pump periodic verification test program. A pump periodic verification test is defined as a test that verifies a pump can meet the required (differential or discharge) pressure as applicable, at its highest design-basis accident flow rate. The applicant or licensee must do the following: (1) Identify those certain applicable pumps with specific design-basis accident flow rates in the applicant’s or licensee’s credited safety analysis (e.g., technical specifications, technical requirements program, or updated safety analysis report) for inclusion in this program. (2) Perform the pump periodic verification test at least once every 2 years. (3) Determine whether the pump periodic verification test is required before declaring the pump operable following replacement, repair, or maintenance of the pump. (4) Declare the pump inoperable if the pump periodic verification test flow rate and associated differential pressure (or discharge pressure for positive displacement pumps) cannot be achieved. (5) Maintain the necessary records for the pump periodic verification tests, including the applicable test parameters (e.g., flow rate and associated differential pressure, or flow rate and associated discharge pressure, and speed for variable speed pumps) and their basis. (6) Account for the pump periodic verification test instrument accuracies in the test acceptance criteria. The applicant or licensee need not perform a pump periodic verification test if the design-basis accident flow rate in the applicant’s or licensee’s safety analysis is bounded by the comprehensive pump test or Group A test.
