: 8. RCIC Restart / Suction - CGNS Technical Specifications follow the model technical specifications with the exception of the " keep filled" instrumentr. tion. The " keep filled" instrumentation for the RCIC systen is not required at GGNS.
9..      Isolation Modifications - A request for amendment will be utilized to update Technical Specification 3.3.2. This update will reflect the minimum response times for the RCIC steam line high flow isolation.
10.. Interlock on Recirculation Pump Loops - This item applies only to non-jet pump plants; it is not applicable to CGNS.
: 11. Common Reference Level - As described in Supplement 2 to the GCNS SER, MP&L committed to modifications which were found to be acceptable to the NRC. GGNS Technical Specification Bases Figure B3/4 3-1 conforms to sample figure in the generic letter.
