Statistical Methods for the Analysis of Fuel Densification.” This RG, which was last revised in 2010, provides guidance for use in predicting the effects of fuel densification in light-water-cooled nuclear power reactors. As discussed in Management Directive 6.6, “Regulatory Guides,” the NRC staff reviews RGs approximately every 5 years to ensure that the RGs continue to provide useful guidance. Documentation of the NRC staff review is enclosed. Based on the results of the periodic review, the staff concludes that no changes to RG 1.126 Revision 2 are warranted at this time. The staff did not identify any technical or regulatory issues in the review. Enclosure: As stated CONTACT: Harold Scott, RES/DSA/FSCB 301-415-1682 DISTRIBUTION: S.

Scott Staff Action Decided: Reviewed with no issues identified 1. What are the known technical or regulatory issues with the current version of the Regulatory Guide (RG)? Regulatory Guide 1.126, Revision 2, "An Acceptable Model and Related Statistical Methods for the Analysis of Fuel Densification," issued in March 2010, describes an analytical model and related assumptions and procedures that the staff of the U.S. Nuclear Regulatory Commission (NRC) considers acceptable for predicting the effects of fuel densification in light-water-cooled nuclear power reactors. To meet these objectives, the guide describes statistical methods related to product sampling that will ensure that this and other approved analytical models will
