- 1.
44 peripheral locations will not physically be lead power assembly.
- 2.
In the Westinghouse Reload Safety Analysis Checklist (RSAC) process, this parameter is identified as a key safety analysis parameter that could be impacted by a fuel reload.
- 3.
The fuel temperature and rod internal pressure data is only provided up to 62,000 MWD / MTU. In addition, the hot assembly / hot rod will not have a burn up this high in ASTRUM analyses.
- 4.
Analyzing the pressurizer as being located on an intact loop is limiting per Westinghouse methodology.
- 5.
