Important Human Actions This SRP chapter can also be used to review changes or modifications to licenses for nuclear power plants that include or result in changes to human actions. While the HSI modification may be a large-scale modernization, even smaller-scale modifications may have important implications for plant risk, especially when they affect operator actions that are credited in the SAR. An HFE review is conducted if such a modification affects the role of personnel or the tasks they perform, the sequence of actions, the timing, or the overall workload, and is potentially significant to plant safety. Modifications affect the role or tasks of personnel if they impose new or different demands on them to operate or maintain the plant, or otherwise ensure safety. An example of such a modification would be substituting manual actions for automatic actions for performing design functions described in the SAR. (See Information Notice (IN) 97-78, “Crediting of Operator Action In Place of Automatic Actions and Modification of Operator Actions, Including Response Times.” for further guidance). Previous revisions of HFE guidance documents have focused on the review of risk-important human actions. Experience is showing that there are additional human actions that need to receive similar reviews because they are specifically credited in
