Request for supplemental response RAI 14.2-53 Original RAI 14.2-53: Revise the DCD Tier 2, Revision 1, Section 14.2.8.1.59, to include testing of the overspeed trip system.
GE Response (MFN-07-061 dated 1/23/2007): The following bullet will be added to DCD Tier 2, Subsection 14.2.8.1.59: Proper operation of the turbine overspeed protection system to provide mechanical overspeed trip and electrical backup overspeed trip as specified in Subsection 10.2.2.4 and the manufacturer's technical instruction manual. (During the preoperational test phase, simulated speed signals will be used for these tests.)
Request for supplemental RAI response: The response and DCD revision that was incorporated into DCD revision 3 Section 14.2.8.1.59 are not accurate since the proposed ESBWR overspeed trip system does not include a mechanical trip device. Please revise the response and provide a proposed DCD revision to exclude the mechanical overspeed trip.
Please provide a date for response to this supplemental RAI.
