Enclosure REQUEST FOR ADDITIONAL INFORMATION RELATING TO THE POWER RANGE NEUTRON MONITOR SYSTEM DIGITAL UPGRADE FOR SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1 AND 2 (SSES 1 AND 2)
DOCKET NOS. 50-387 AND 50-388 The Nuclear Regulatory Commission (NRC) staff is reviewing the proposed license amendment from PPL Susquehanna, LLC (PPL, the licensee) to Facility Operating License No. NPF-14 and NPF-22 related to the installation of the General Electric (GE) Nuclear Measurement Analysis and Control (NUMAC) Power Range Neutron Monitor (PRNM) System for SSES 1 and 2. The NRC staff has determined the information requested below will be needed to complete its review.
- 1.
In PPLs application dated June 27, 2005, Section 7.2, Plant Specific Actions Required by NEDC-32410P-A, the following additional information is requested to support the NRC staff review:
A.
In response to Section 2.3.4, PPL identified the existing plant variation, with regards to the Average Power Range Monitor/Rod Block Monitor/Technical Specifications (ARTS), as 2.3.3.5.1.4, ARTS not implemented and not planned, and the replacement PRNM alternative as Non-ARTS variation of STP
[simulated thermal power] trip setpoint algorithm.... In light of the Phase 2 implementation, incorporation of ARTS logic, explain why the ARTS variation and implementation was not the selected option.
B.
In response to Section 4.4.2.3.4, PPL responded with, Evaluations to confirm that the maximum seismic accelerations at the mounting locations of the equipment do not exceed qualification limits of the equipment will be completed...The seismic qualification results will be documented in a plant-specific Qualification Summary. Please provide to the NRC staff the Qualification Summary which should include verification that the results, including updates from the original configuration by GE, incorporate the SSES 1 and 2 spectrum.
C.
Supplement 1 of GE Licensing Topical Report NEDC-32410P-A, NUMAC PRNM Retrofit Plus Option III Stability Trip Function, was not referenced for Section 8.4.4.3.4, which stated, The utility action in the base report applies except that OPRM Trip is replaced by OPRM Upscale. This action has yet to be implemented, please explain.
2.
In Section 2.1 of the submittal, several Technical Specification (TS) changes have been proposed relating to Reactor Protection System instrumentation functions, including changes in terminology in the current TSs. If the proposed TS changes represent any alteration or adjustment of the instrument safety function, then describe the differences between the function before and after the upgrade, the methodology used to justify the change, and if the methodology was approved by the NRC staff.
