U.S. Nuclear Regulatory Commission.
Availability of draft rule wording.
The Nuclear Regulatory Commission (NRC) is making available the draft wording of a possible amendment of its regulations. The proposal would amend 10 CFR 50.44, “Standards for combustible gas control system in light-water-cooled power reactors,” and associated regulations based on experience gained from a fundamental reevaluation of the need for the regulation, the application of risk insights, and the incorporation of performance-based concepts, to the degree practicable. The proposed changes effectively “rebaselines” the existing regulation for current licensees and consolidates combustible gas control regulations for future applicants and licensees. The changes should reduce the regulatory burden for all applicants and licensees and improve the effectiveness of 10 CFR 50.44. Additional conforming changes to 10 CFR 50.34, 50.46, and 10 CFR part 52 are also identified. The availability of the draft wording is intended to inform stakeholders of the current status of the NRC staff's activities to amend 10 CFR 50.44 and to provide stakeholders the opportunity to comment on the draft changes. The NRC staff has also provided additional information within the body of the draft rule language which is bracketed (“[ ]”) to facilitate understanding of the staff's intent and the development of guidance for the proposed rule. As a result of the draft wording changes, certain technical specifications in the standard technical specifications can be deleted or modified. The NRC staff is also making the draft technical specification changes associated with the draft wording of 10 CFR 50.44 available for stakeholders comments. The draft changes to NUREGs 1430, 1431, 1432, 1433, and 1434 are attached.
Comments should be submitted by December 31, 2001. Any comments received after this date may not be considered during drafting of the proposed rule. Because of scheduling considerations in preparing a proposed rule, the NRC staff requests that stakeholders provide their comments at their earliest convenience before the end of the comment period, if practicable.
Submit written comments to: Secretary, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, Attention: Rulemakings and Adjudications Staff, Mail Stop O-16C1 or deliver written comments to One White Flint North, 11555 Rockville Pike, Rockville, Maryland, between 7:30 a.m. and 4:15 p.m. on Federal workdays.

Since the Commission published a Policy Statement on the Use of Probabilistic Risk Assessment in 1995, the NRC staff's efforts to consider risk insights in the regulatory infrastructure have evolved over the years. In SECY-98-0300, dated December 23, 1998, under Option 3, the staff proposed to add provisions to Part 50 for risk-informed alternative regulations, revise existing requirements to reflect risk-informed considerations, and to remove unnecessary or ineffective regulations. In SECY-00-0198, dated September 14, 2000, the staff provided specific recommendations for risk-informed changes to 10 CFR 50.44. In a Staff Requirements Memorandum dated January 19, 2001, the Commission directed the staff to proceed with risk-informed revisions to 10 CFR 50.44. In SECY-01-0162, dated August 23, 2001, the NRC staff subsequently communicated to the Commission its recommended approach and discussed issues involving 10 CFR 50.44.
During the development of the Option 3 effort, Mr. Bob Christie of Performance Technology, Inc. submitted letters dated October 7 and November 9, 1999 that requested changes to the regulations in 10 CFR 50.44. These letters have been characterized as a petition for rulemaking and assigned the Docket No. PRM-50-68. The petition was published for comment in the Federal Register on January 12, 2000 (65 FR 1829). The issues associated with 10 CFR 50.44 which were raised by the petitioner were discussed in SECY-00-0198 and will be addressed in the proposed rulemaking.
The NRC also received a petition for rulemaking filed by the Nuclear Energy Institute. The petition was docketed on April 12, 2000, and has been assigned Docket No. PRM-50-71. The petition was published for comment in the Federal Register on May 30, 2000 (65 FR 34599). The petitioner requests that the NRC amend its regulations to allow nuclear power plant licensees to use zirconium-based cladding materials other than zircaloy or ZIRLO, provided the cladding materials meet the requirements for fuel cladding Start Printed Page 57002performance and have received approval by the NRC staff. The petitioner believes the proposed amendment would improve the efficiency of the regulatory process by eliminating the need for individual licensees to obtain exemptions to use advanced cladding materials which have already been approved by the NRC. The issues associated with 10 CFR 50.44 which were raised by the petitioner will also be addressed in the proposed rulemaking.
The NRC has now developed draft wording for the changes to its regulations and has made them available on the NRC's rulemaking Web site at http://ruleforum.llnl.gov. This draft rule language is preliminary and may be incomplete in one or more respects. This draft rule language was released to inform stakeholders of the current status of the 10 CFR 50.44 update rulemaking and to provide stakeholders with an opportunity to comment on the draft revisions. Comments received prior to publishing the proposed rule will be considered in the development of the proposed rule. Comments may be provided through the rulemaking Web site at http://ruleforum.llnl.gov or by mail as indicated under the ADDRESSES heading. The NRC may post updates periodically on the rulemaking Web site that may be of interest to stakeholders.Start Signature
