d by reference into NRC regulations nor endorsed in an RG, then the secondary reference is neither a legally-binding requirement nor a “generic” NRC approved acceptable approach for meeting an NRC requirement. However, licensees and applicants may consider and use the information in the secondary reference, if appropriately justified, consistent with current regulatory practice, and consistent with applicable NRC requirements. C. STAFF REGULATORY GUIDANCE The guidance in IEEE Std. 382-2006 provides an acceptable approach to the NRC staff for meeting the agency’s regulatory requirements for environmental qualification of safety-related power- operated valve actuators in nuclear power plants with the exceptions and additions listed in this section. The guidance also provides an adequate basis for complying with the qualification testing requirements of Criterion III, “Design Control” of Appendix B to 10 CFR Part 50 to verify adequacy of design for service under DBE conditions subject to the following modifications. 1. Section 1.2 of IEEE Std. 382-2006 references IEEE Std. 323-2003, “IEEE Standard for Qualifying Class 1E Equipment for Nuclear Power Generating Stations,” (Ref. 14) which provides guidance on demonstrating the qualification of safety-related equipment including components of any interface whose failure could adversely affect the performance of safety- related systems and electric equipment. As of the date of this RG, the NRC staff does not endorse IEEE Std. 323-2003 or IEEE Std. 323-1983 as acceptable means of meeting regulatory requirements for qualifying equipment for operations in harsh environments. 2. To the extent practical, auxiliary equipment (e.g., limit switches) that are not integral with the actuator mechanism but will be part of the installed actuator assembly should be tested in accordance with guidance in IEEE Std. 382-2006. 3. The applicants and licensees should perform environmental qualification of safety-related actuators
