l from the nameplate data were compared to information given in the Licensee's submittal.
The following safety evaluatian incorporates the YAEC submittal and the Franklin Research Center technical evaluation report (TER).
i 3.1 COMPLETENESS OF S AFETY-RELATED EQUIPMENT In accordance with the DOR guidelines, the licensee was directed to establish a list of systems and display instrumentation needed to mitigate the conse-quences of a LOCA or HELB, inside or outside containment, and reach safe shutdown. The lists of safety-related systems and display instrumentation were developed f rom a review of plant safety analyses and emergency procedures.
The display instrumentation selected includes parameters to monitor overall plant performance as well as to monitor performance of the systems on the list. The systems list was established on the basis of the functions that must be performed fcr mitigation of the consequeros. of a LOCA.ir HELB without regard to location of equipment relat'ive to a potentially hostile environment. The staff has determined and verified that the systems considered by the licensee are those required to echieve or support:
(1 ) emergency reactor shutdown, (2) containment isolation, (3) reactor core cooling, (4) containment heat removal, 43) core residual heat removal, and (6) prevention of significant release of radioactive material to the environment. In addition to the concerns identified below the staff's system review has not included those equipment items discussed in section 5.0 of this report. The systems and instrumentation list is contained in Appendix D.
The licensee submitted an extensive list of safety-related electrical equipment. This list was evaluated and identical components within a plant area exposed to the s;2me e,1vironment were grouped; 24 item types 5
