          About NRC  How We RegulateThe Committee To Review Generic Requirements (CRGR)
The Committee to Review Generic Requirements (CRGR) reviews proposed generic and facility-specific backfitting and forward fitting that are to be imposed on all power reactors and/or selected nuclear materials facilities that are licensed by the U.S. Nuclear Regulatory Commission (NRC). Note, throughout these pages, backfitting is to be interpreted in general as including forward fitting where applicable.The purpose of these reviews is to ensure that such backfitting are appropriately justified based on the backfit provisions of applicable NRC regulations and the Commission's backfit policy. Specifically, Title 10, Section 50.109, of the *Code of Federal Regulations* (10 CFR 50.109) defines a *backfit* as "the modification of or addition to systems, structures, components, or design of a facility; or the design approval or manufacturing license for a facility; or the procedures or organization required to design, construct or operate a facility; any of which may result from a new or amended provision in the Commission's regulations or the imposition of a regulatory staff position interpreting the Commission's regulations that is either new or different from a previously applicable staff position." *Generic backfits* are those that apply to one or more classes of nuclear power reactors or materials facilities. *Facility-specific backfits* applies to a nuclear power reactor or a materials facility.

As an advisory committee to the NRC's Executive Director for Operations (EDO), the CRGR's primary responsibilities are to recommend either approval or disapproval of the staff's proposed backfits, and to guide and assist the NRC's program offices in implementing the Commission's backfitting policy. The CRGR Charter is incorporated in Management Directive 8.4, "Management of Backfitting, Forward Fitting, Issue Finality, and Information Requests," as well as various program office administrative procedures for developing new or revised generic actions.

The CRGR also provides an annual report to the Commission describing the CRGR's activities during the previous year, as well as its decisions regarding the various topics that the CRGR reviewed during the year. As an additional responsibility, the CRGR reviews the NRC's administrative backfit controls to ensure that they are sufficient and that the related staff guidance is comprehensive and clear.
