Performance Indicator Guidance

  • IMC 0608, "Performance Indicator Program"
  • IMC 0308, Attachment 1, "Technical Basis for Performance Indicators"
  • NEI 99-02, Revision 7, "Regulatory Assessment Performance Indicator Guideline." The current revision of NEI 99-02 is a document jointly produced by the Nuclear Energy Institute (NEI) and the NRC and published by NEI that contains guidance for calculating and reporting PI data that the NRC uses in its assessment of commercial power reactor licensee performance. This document should be used for PI data collection as of October 1, 2013 and incorporates Frequently Asked Questions that were approved through March 2013.
  • The ROP Performance Indicator Frequently Asked Question (FAQ) process is used to resolve interpretation issues with NEI 99-02. The FAQ process and white papers may also be used to propose changes to NEI 99-02 guidance and the PI Program. The NRC and industry review FAQs and white papers and work to achieve resolution during periodic public meetings. IMC 0608 and Appendix E of NEI 99-02 contain additional information about the FAQ and white paper processes. FAQs and white papers that contain plant-specific security information will not be publicly available to help prevent provision of potentially useful information to a possible adversary.
    • Draft FAQs are FAQs that have been introduced at the public ROP working group meetings and that are pending resolution. Draft FAQs are updated and modified based on NRC and industry discussions during public meetings. Once the NRC approves a draft FAQ, it will be removed from the draft FAQs list and added to the approved FAQs list.
    • Approved FAQs (updated as of May 30, 2018) are FAQs for which the NRC and industry have resolved since the latest revision of NEI 99-02. Approved FAQs should be used in conjunction with the latest revision of NEI 99-02 to determine the current guidance for performance indicator collection and reporting. Approved FAQs will be incorporated into the next revision to NEI 99-02 and then moved into the archived FAQ list on this Web site. To begin receiving updates to approved FAQs by e-mail, please visit our Subscribe to E-mail updates page and follow the instructions at the GovDelivery Subscription Services link.
    • Archived FAQs that have been that have been resolved prior to or superseded by the latest revision of NEI 99-02 and are included on this Web site for reference purposes. Archived FAQs also contain withdrawn FAQs since the latest revision of NEI 99-02.
