ification * Conducting training to maximize personnel's knowledge of and skill with the new design before its implementation B.2 Operating Experience Review The operating experience of the plant being modified should be reviewed as part of the OER. B.3 Functional Requirements Analysis and Function Allocation Functional requirements analysis and function analysis should consider the following (as identified in NUREG-071 1): " Functional requirements analyses for modifications that are likely to change existing safety functions, introduce new functions for systems supporting safety functions, or involve unclear functional requirements that may be important to safety. "* Function allocation analyses for modifications that are likely to change the allocation between personnel and plant systems of functions important to safety. "* A change in an operator's role due to a modification should be examined within the context of its effects on the operators overall responsibilities. B.4 Task Analysis -' The following considerations should be addressed in the review of plant modifications that are likely to affect human actions (HAs) previously identified as risk-important, cause existing HAs, to become risk-important, or create new actions that are risk-important (as identified in NUREG 0711): DRAFT Rev. 1 - December 2002 18.0-10 " The tasks analyses should be revised and updated to reflect requirements of the modification; the scope should include tasks involving the modification and its interactions with the rest of the plant, including those resulting from functions addressed in theaihalyses of functi6nal'requiremerits and fifnction allocation. -For maintenance, tests, in-se'ctions,' aind s'urveillances, attention should be given to risk-important actions :that are newv or supported by new technologies (e_.g., new capabilities for online maintenance). " The task analysis should identify the design charact6risticsof the existing HSIs that support the p'erformance of
