e 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 using the guidance in RG 1.89. This testing includes a combination of type testing, RG 1.73, Rev. 1, Page 5 operating experience, and analysis rather than just type testing and operating experience, ongoing qualification, or a combination thereof. Type testing is the preferred method of equipment qualification because other methods may be based on older or dissimilar equipment that may not be comparable to the equipment being qualified. 4. The radiological source term for qualification tests in a nuclear radiation environment should be based on the source term methodology used in RG 1.89 or RG 1.183. The containment size should be taken into account in each case. For exposed organic materials, calculations should take into account both beta and gamma radiation. 5. Section 2, "Normative References," of IEEE Std. 382-2006, lists additional applicable IEEE standards. The specific applicability or acceptability of these referenced standards is discussed in the paragraph titled “Documents Discussed in Staff Regulatory Guidance” in Section B of this RG. 6. The environmental qualification criteria described in Section 6, "Qualification Testing of Selected Actuators in Generic Actuator Group," and Section 7, "Qualification of Actuator for Specific Application," of IEEE Std. 382-2006 should be used to qualify actuators in generic and specific applications, respectively, unless the anticipated actual service operating sequence for the actuator is expected to create a more severe impact than described in Section 6.3.2, "Test Sequence and Requirements." In such case, the actual 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
