- 2. IMC 0609 App M 04/12/12 IMC 0609 App M 01/10/19 TRAINING: No special training is required for any documents issued with this Change Notice.
REMARKS: IMC 0308 Attachment 3 Appendix M, Technical Basis for the Significance Determination Process (SDP) Using Qualitative Criteria, has been revised to conform to the changes in IMC 0609 Appendix M. Events since original issuance are added to the Background section.
IMC 0609 Appendix M, Significance Determination Process Using Qualitative Criteria, has been revised to provide clarification of the existing entry conditions to more clearly illustrate when Appendix M should be used. In addition, provided clarification of the existing decision-making attributes to align with the enhanced guidance in Revision 3 of Regulatory Guide 1.174, An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis, which was issued in January 2018. Also, the description of the initial evaluation was clarified to better align with intent/practice, since the previous description inferred that (in the case of a quantitative estimate) one would use enveloping input assumptions across-the-board. Finally, ROPFF 0609M-2272 was addressed to make the guidance more useful for RP and EP findings. A Commissioners Assistant note was issued (ML18311A027) to notify the Commission of the described changes in accordance with Management Directive 8.13 and COMSECY-16-0022.
