Notes:

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. Parameter values affected by evaluation described in Section 14.3.1.5.1
