l design and qualification of the mechanical, electrical, and I&C equipment. The program is measured against the acceptance criteria listed in Subsection II of this SRP section. Of particular interest to the reviewer is the proper use of test and analytical procedures. Equipment should be tested unless testing of the component is impractical due to size limitations or partial type-test data are provided to support the analytical assumptions and conclusions reached. The environmental design and qualification program is reviewed for the identification of normal, accident, and post-accident environmental conditions; anticipated operational occurrences; required operating time; and chemical, submergence, aging, synergistic effects, and margin considerations, including the acceptance criteria of the test results. 2. At the OL stage, the staff reviews the program again, as described by the applicant in the FSAR. In addition, the FSAR is reviewed for documentation of the successful implementation of the environmental design and qualification program, including test and analytical results. The reviewer verifies that the applicant's list of systems, which includes the list of equipment associated with each such system, is consistent with the definition of the systems and equipment described in Subsection I, Item 1, of this SRP section. At the time of the OL application, the reviewer confirms that complete records are retained at a facility in an auditable and readily accessible form, which describe the environmental design and qualification method used for all mechanical, electrical, and I&C equipment in sufficient detail to document the degree of compliance with the 3.11 -21 Draft Revision 4 – December 2017 requirements discussed herein. The reviewer also confirms that, thereafter, such records will be updated and maintained current as equipment is replaced, tested, or otherwise qualified. To confirm the extent to which the equipment meets the requirements of Subsection
