The U.S. Nuclear Regulatory Commission (NRC) invites public comment about our intention to request the OMB's approval for renewal of an existing information collection that is summarized below. We are required to publish this notice in the Federal Register under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. chapter 35). Information pertaining to the requirement to be submitted: 1. The title of the information collection: 10 CFR Part 72, Licensing Requirements for the Independent Storage of Spent Nuclear Fuel, High-Level Radioactive Waste and Reactor-Related Greater than Class C Waste. 2. Current OMB approval number: 3150-0132. 3. How often the collection is required: Required reports are collected and evaluated on a continuing basis as events occur; submittal of reports varies from less than one per year under some rule sections to up to an average of about 80 per year under other rule sections. Applications for new licenses, certificates of compliance (CoCs), and amendments may be submitted at anytime; applications for renewal of licenses are required every 40 years for an Independent Spent Fuel Storage Installation (ISFSI) or CoC effective May 21, 2011, and every 40 years for a Monitored Retrievable Storage (MRS) facility. 4. Who is required or asked to report: Certificate holders and applicants for a CoC for spent fuel storage casks; licensees and applicants for a license to possess power reactor spent fuel and other radioactive materials associated with spent fuel storage in an ISFSI; and the Department of Energy for licenses to receive, transfer, package and possess power reactor spent fuel, high-level waste, and other radioactive materials associated with spent fuel and high-level waste storage in an MRS. 5. The number of annual respondents: 68. 6. The number of hours needed annually to complete the requirement or request: 62,692 hours (26,106 reporting + 33,416 recordkeeping + 3,170 third party disclosure). 7. Abstract: 10 CFR part 72 establishes mandatory requirements, procedures, and criteria for the issuance of licenses to receive, transfer, and possess power reactor spent fuel and other radioactive materials associated with spent fuel storage in an ISFSI, as well as requirements for the issuance of licenses to the Department of Energy to receive, transfer, package, and possess power reactor spent fuel and high-level radioactive waste, and other associated radioactive materials in an MRS. The information in the applications, reports, and records is used by NRC to make licensing and other regulatory determinations. Submit, by August 8, 2011, comments that address the following questions: 1. Is the proposed collection of information necessary for the NRC to properly perform its functions? Does the information have practical utility? 2. Is the burden estimate accurate? 3. Is there a way to enhance the quality, utility, and clarity of the information to be collected? 4. How can the burden of the information collection be minimized, including the use of automated collection techniques or other forms of information technology? The public may examine and have copied for a fee publicly available documents, including the draft supporting statement, at the NRC's Public Document Room, Room O-1F21, One White Flint North, 11555 Rockville Pike, Rockville, Maryland 20852.

The Nuclear Regulatory Commission has issued for public comment a document entitled: NUREG/CR-XXXX, ``Development of Quantitative Software Reliability Models for Digital Protection Systems of Nuclear Power Plants, Draft Report for Comment.''
Domestic Licensing of Source Material-Amendments/Integrated Safety Analysis
Document Number: 2011-11927
Type: Proposed Rule
Date: 2011-05-17
Agency: Nuclear Regulatory Commission, Agencies and Commissions
The U.S. Nuclear Regulatory Commission (NRC or the Commission) is proposing to amend its regulations by adding additional requirements for source material licensees who possess significant quantities of uranium hexafluoride (UF6). The proposed amendments would require such licensees to conduct integrated safety analyses (ISAs) similar to the ISAs performed by 10 CFR part 70 licensees; set possession limits for UF6 for determining licensing authority (NRC or Agreement States); add defined terms; add an additional evaluation criterion for applicants who submit an evaluation in lieu of an emergency plan; require the NRC to perform a backfit analysis under specified circumstances; and make administrative changes to the structure of the regulations. The proposed ISA requirements would not apply to facilities that are currently undergoing decommissioning under the current regulations. This rulemaking pertains to 10 CFR part 40 licensees and applicants who possess, or plan to possess, significant quantities of UF6. The current regulations do not contain ISA requirements for evaluating the consequences of facility accidents. The proposed amendment would require applicants and licensees who possess or plan to possess significant amounts of UF6 to conduct an ISA and submit an ISA summary to the NRC. The ISA, which evaluates and categorizes the consequences of accidents at NRC licensed facilities, would address both the radiological and chemical hazards from licensed material and hazardous chemicals produced in the processing of licensed material. Similar hazards that exist at other fuel cycle facilities are addressed by ISA requirements elsewhere in the regulations. The NRC is also proposing new guidance on the implementation of the additional regulatory requirements for licensees that would be authorized under this rulemaking.
