designed so as to have an extremely low probability of rapidly propagating failure or of gross rupture. E. General Design Criterion 15, as it relates to the reactor coolant system being designed with sufficient margin to assureensure that the reactor coolant pressure boundary will not be breached during normal operating conditions, including anticipated operational occurrences. Specific criteria necessary to meet the relevant requirements of the Commission regulations identified above are as follows: 1. Relevant requirements of GDC General Design Criteria 1, 2, 4, 14, and 15 are met if 25 vibration, thermal expansion, and dynamic effects testing are conducted during startup functional testing for specified high-and moderate-energy piping, and their supports and restraints. The purpose of these tests is to confirm that the piping, components, restraints, and supports have been designed to withstand the dynamic loadings and operational transient conditions that will be encountered during service as required by the Code and to confirm that no unacceptable restraint of normal thermal motion occurs. An acceptable test program to confirm the adequacy of the designs should consist ofinclude the following: 26 a. A list of systems that will be monitored. 3.9.2-7 DRAFT Rev. 3 - April 1996 b. A listing of the different flow modes of operation and transients such as pump trips, valve closures, etc. to which the components will be subjected during the test. (For additional guidance see Reference 8Regulatory Guide 1.68. ) For 27 example, the transients associated with the reactor coolant system heatup tests should include, but not necessarily be limited to: (1) Reactor coolant pump start. (2) Reactor coolant pump trip. (3) Operation of pressure-relieving valves. (4) Closure of a turbine stop valve. c. A list of selected locations in the piping system at which visual inspections and measurements (as needed) will be performed during the tests. For each of these selected locations,
