Without documenting how data may have been manipulated, the impacts of that manipulation Clarification (e) the sources of data, and the collection process and data manipulation performed in support of the Newly Developed Methods; RG 1.247, Appendix A, Page A-85 Table A-22. Staff Position on ASME/ANS RA-S-1.4-2021, Newly Developed Methods Index No. Issue Position Resolution may not be understood and, depending on how the data is manipulated, the use of the NDM in the PRA could potentially underestimate risk.
