o verify that the above seismic and safety classifica- tions have been included, and that the P&IDs indicate any points of change in piping quality group classification. c. Design provisions have been made that permit appropriate inservice inspection and functional testing of system components important to safety. It will be acceptable if the SAR information delineates a testing and inspection program and if the system drawings show the necessary test recirculation loops around pumps or isolation valves that would be required by this program. 9.2.1-5 Rev. 4 - June 1986 d. The review of seismic design is performed by the structural and geo- technical reviewer of EB and the review for seismic and quality group classification is performed by the mechanical engineering reviewer of EB as indicated in subsection I of this SRP section. 3. The reviewer determines that the safety function of the system will be maintained, as required, in the event of adverse environmental phenomena such as earthquakes, tornadoes, hurricanes, and floods, or in the event of certain pipe breaks or loss of offsite power. The reviewer uses engi- neering judgment, the results of a failure mode and effects analyses, and the results of reviews performed under other SRP sections to verify the following: a. The failure of portions of the system or of other systems not designed to seismic Category I and located close to essential por- tions of the system, or of non-seismic Category I structures that house, support, or are close to essential portions of the SWS, will not preclude operation of the essential portions of the SWS. Refer- ence to SAR Chapter 2 describing site features and the general arrangement and layout drawings will be necessary as well as the SAR tabulation of seismic design classifications for structures and sys- tems. Statements in the SAR that verify that the above conditions are met are acceptable. (CP) b. The essential portions of the SWS are protected from the effects of floods,
