Subject:
Report of Changes and Errors to 10CFR50.46 River Bend Station - Unit 1 Docket No. 50-458 License No. NPF-47 Reference : 1. Letter RBG-45789, "Report of Changes and Errors to 10CFR50.46,"
dated September 27,2017
Dear Sir or Madam :
There has been no notice of changes or errors associated with the RBS ECCS analysis since the last 10CFR50.46 report provided to the NRC (Reference 1). The table below summarizes the effects on the current ECCS analysis performed by General Electric -
Hitachi Nuclear Energy (GEH) using their NRC approved SAFER/GESTR - LOCA methodology.
Since the last 10 CFR 50.46 report provided to the NRC, RBS is currently in Cycle 20 with the RBS core composed of the GNF2 and GNF3 fuel types .
GNF3 is the limiting fuel type with a PCT of 1830°F incorporating 10 CFR 50.46 error notifications up to and including NL-2017-02. As can be seen the PCT for the GNF3 fuel remains well below the 2200 0 F acceptance criteria of 10 CFR 50.46.
