ual service sequence should be used in the test. 7. Section 12.3, "Test Conduct," of IEEE Std. 382-2006 for Cycle Aging Tests, provides a representative number of cycles for the valve application. The applicant or licensee will be responsible for qualifying the actuator for its qualified life including its design cycles, as specified in the design requirements for new nuclear power plants or plants receiving license renewal for plant life extension. 8. Section 14, “Vibration Aging Test,” of IEEE Std. 382-2006 states that the vibration aging test is intended to provide a vibratory environment that is representative of normal plant induced vibration including system operating transients and other dynamic vibratory environments. The environmental qualification for power-operated valves should also address flow-induced vibration caused by acoustic resonance and hydraulic loading in the reactor, steam, and feed- water systems. 9. The NRC staff considers the guidance in IEEE Std. 382-2006 section 15 as an acceptable method for the environmental qualification of valve actuators as part of the qualification process for power-operated valves described in RG 1.100 subject to the following provisions: 9.1 Section 15.3(b) of IEEE Std. 382-2006 states, “Each sweep shall be from 2 Hz to 35 Hz to 2 Hz, or other enveloping frequency range specified by the user." This requirement should be replaced with the following… “Each sweep shall be from 2Hz to 64Hz to 2Hz or, if the Required Response Spectra (RRS) has a frequency range exceeding 64Hz, then the frequency sweep should be consistent with the RRS of the specific plant equipment.” 9.2 Section 15.3(c), of IEEE Std. 382-2006 states, for HRHF site plants, “...at one-third octave interval test frequencies indicated on Figure 1.” This should be replaced with the following: “…the frequency interval should be one-sixth octave to adequately identify resonance frequencies.” The users of IEEE Std. 382-2006 need to
