Supplemental Information.in Response to

-" ^ . RAIL-Remote Shutdown ' (License Condition A14) RAI Ia Information should be provided to give a one-to-one comparison of the final ~ (after modifications) redundant safety-related train of equipment with that of the~already existing safety-related remote-shutdown ' train of equipment which was reviewed and accepted by the staff prior to licensing.-

Response

Attachment.5 provid'es a comparison of the existing single train g of safety-grade remote shutdown-equipment as described in FSAR Table 7.4-3, and the interim redundant remote shutdown capability..Each existing component has been evaluated for its. . worst case failure, and each component's associated system design function has.been verified to have been included in the interim redundant remote shutdown capability. The final redundant remote shutdown capability will be functionally equivalent to the interim redundant remote shutdown capability. The only changes expected to be incorporated into the final redundant remote shutdown capability are: A. Eliminate the steps required to install temporary jumpers and replace them with steps referencing the operation of transfer and control switches to establish control of the - B' RHRSW, RHR, & ESW pumps. B. Incorporate the changes necessary-to provide seismically qualified indication loops as identified in the . response to item Ic. These changes will have no impact on the comparison of the I existing. single train of safety-grade remote shutdown equipment and the interim remote shutdown capability, consequently the comparison 'also applies to the final redundant remote shutdown capability. RAI: Ib. That portion of the operational procedures to be implemented for ^ the final (after modifications) redundant safety-related remote shutdown system. (both trains) should be provided.

Responsei ' ne design changes'ndeessary to permit full implementation of the redundant safety-grade remote shutdown capability consist of providingcsafety-grade, seismically qualified indication loops. for RCIC: flow, reactor vessel pressure and level, RHR loop A. flow, and suppression pool. level. -This indication is to be provided on I' the-remote shutdown panel.

Additional design changes have been initiated to allow-the . operation of theB' ESW, 'B' RHR,.and 'B' RHRSW pumps from their respective pump motor circuit breaker cubicles,-without the need to x installitemporary jumpers.
