are commensurate with safety and how IOE was taken into account will be reviewed during NRC inspection. ii. The process for disposition of SSCs in 50.65(a)(1) status that do not meet goals, including administration of corrective action as prescribed by program procedures. The applicant should describe how procedures ensure prompt, comprehensive and thorough corrective action that (a) addresses the proximate and ultimate causes of degraded performance or condition, (b) encompasses the extent of condition, and (c) institutes preventive measures, including changes that may be required in maintenance and/or maintenance support practices, procedures and training. This discussion should also address how failures will be evaluated against MR functions, since not all failures that cause loss of some function are MR functional failures, and also how maintenance- preventable functional failures will be identified and dispositioned. 17.6-8 March 2007 iii. Any plant management policies, procedures or practices that involve the 50.65(a)(1) status of MR SSCs, e.g., for MR staff performance evaluation, etc. B. The process for determining which SSCs within the scope of the MR program will be tracked to demonstrate effective control of their performance or condition in accordance with paragraph 50.65(a)(2) as prescribed by program procedures. The 50.65(a)(2) procedures should address the following: i. The process for developing performance criteria or condition monitoring criteria used to demonstrate effective control of performance or condition for SSCs in 50.65(a)(2) status as prescribed by program procedures. The applicant’s submittal should explain how the program ensures that performance criteria are commensurate with safety (including PRA risk insights) and good engineering practice, take industry operating experience into account, and are reasonable and sensible, i.e., achievable and sufficiently sensitive to degraded performance or condition such that meeting them could
