ted to, the following: (i) Reactor coolant pump start. (ii) Reactor coolant pump trip. (iii) Operation of pressure-relieving valves. (iv) Closure of a turbine stop valve. 3.9.2-15 Revision 4 – March 2017 C. A list of all potential flow-induced resonance conditions and whether testing reveals their presence at typical plant operating conditions. In particular, the lock-in of flow instability modes with acoustic resonances due to pipe flow over side branches needs to be assessed. D. 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, the deflection (peak-to-peak), pressure, or other appropriate criteria to demonstrate that the stress and fatigue life are within the allowable design limits should be provided. E. A list of snubbers on systems that experience sufficient thermal movement to measure snubber travel from cold to hot position. F. A description of the thermal motion monitoring program (i.e., verification of snubber movement, adequate clearances and gaps, and acceptance criteria and methods for measuring motion). G. If vibration is noted beyond the acceptance limits set by the criteria of Item II.1.D above, corrective restraints should be designed, incorporated in the piping system analysis, and installed. If during the test piping system restraints are determined to be inadequate or are damaged, corrective restraints should be installed and another test should determine whether the vibrations have been reduced to an acceptable level. If no snubber piston travel is identified, the corrective action to be taken to ensure that the snubber is operable should be described. 2. To meet the requirements of GDC 2, acceptance criteria for the areas of review identified in subsection I.2 of this SRP section are described below. Other approaches that are justified as equivalent to or more conservative than the stated acceptance criteria may be
