n of all mechanical and electrical systems required to perform the functions defined in paragraph 1 of subsection Ithe second paragraph of subsection I.20 2. Identification of the environmental design bases for the equipment identified, including the definition of theanticipated operational occurrences and normal, abnormal, accident, 21 and postaccident environments. 3. Requirements for documentation of the qualification tests and analyses that have been 22 or will be performed on the equipment to meet the design bases. 4. Demonstration of the adequacy of the environmental qualification program. At the operating license (OL) stage, the staff reviews the applicant's environmental qualification program and the submitted results of its implementation. The staff additionally will audit the 3.11-3 DRAFT Rev. 3 - April 1996 applicant's central file. The audit consists of a staff review of the documentation provided in the file to demonstrate tangible evidence of qualification. The staff's review is performed to 23 determine (1) proper implementation of criteria established in the CP review and (2) adequate environmental qualification for all mechanical and electrical equipment. The staff's review for design certification consists of an evaluation of the applicant's submittal on its approach for selecting and identifying equipment required to be environmentally qualified for the standard design. For combined license (COL) applicants referencing a certified design, the staff will review specific details of the plant's environmental qualification program using the acceptance criteria and review procedures described in this SRP section.24 Seismic and dynamic qualification of mechanical and electrical equipment is addressed in SRP Section 3.10. Protection of mechanical and electrical equipment against other natural phenomena and external events is addressed in other SRP sections as follows and as described under Review Interfaces in this subsection.25 The SPLB reviews SAR
