1.

Chapter 13 section 13.2.1, Step Reactivity Insertion - Provide a reactivity transient analysis using a verified and validated analysis method that demonstrates that the worst case credible reactivity transient consistent with the limitations specified in the technical specifications (TS) does not result in exceeding the heat flux and temperature limitations of the fuel as described in the safety analysis report (SAR). The inputs and assumptions used in the analysis should be conservative selections of the ranges of each input parameter and should be able to be determined from information provided in the SAR and TS. The results of the analysis should account for the uncertainties in the input parameters and the analysis methodology.
