Title:
Post Fire Safe Shutdown (PFSSD) Analysis Wolf Creek document #: XX-E-013-004- Revision #: N/A CN005 ECDE: Enercon No. Question Instructions and Guidance YES NO N/A 1 Do assumptions have All Assumptions should be stated in clear sufficient documented terms with enough justification to confirm X rationale? that the assumption is conservative:
For example, 1) the exact value of a particular parameter may not be known or that parameter may be known to vary over the range of conditions covered by the Calculation. It is appropriate to represent or bound the parameter with an assumed value.
- 2) The predicted performance of a specific piece of equipment in lieu of actual test data. It is appropriate to use the documented opinion/position of a recognized expert on that equipment to represent predicted equipment performance.
Consideration should also be given as to any qualification testing that may be needed to validate the Assumptions. Ask yourself, would you provide more justification if you were performing this analysis? If yes, the rationale is likely incomplete.
2 Are assumptions Ensure the documentation for source and compatible with the rationale for the assumption supports the way X way the plant is the plant is currently or will be operated post operated and with the change and they are not in conflict with any licensing basis? design parameters. If the Analysis purpose is to establish a new licensing basis, this question can be answered yes, if the assumption supports that new basis.

Due dates for these actions need to support verification prior to the analysis becoming operational or the resultant plant change being op authorized.
4 Do the design inputs The origin of the input, or the source should have sufficient be identified and be readily retrievable within X rationale? WCNOC's documentation system.
If not, then the source should be attached to the analysis. Ask yourself, would you provide more justification if you were performing this analysis? If yes, the rationale is likely incomplete.
5 Are design inputs The expectation is that an WCNOC Engineer correct and reasonable should be able to clearly understand which X with critical input parameters are critical to the outcome of parameters identified, the analysis. That is, what is the impact of a if appropriate? change in the parameter to the results of the analysis? If the impact is large, then that parameter is critical.
