In-Core Thermocouples at Different Elevations and Radial Positions in Reactor Core
The U.S. Nuclear Regulatory Commission (NRC) is denying a petition for rulemaking (PRM), PRM-50-105, submitted by Mark Leyse (the petitioner) on February 28, 2012. The petitioner requested that the NRC require all holders of operating licenses for nuclear power plants (NPPs) to operate NPPs with in-core thermocouples at different elevations and radial positions throughout the reactor core to enable the operators to accurately measure a large range of in-core temperatures in NPP steady-state and transient conditions. The NRC is denying the PRM because: there are no protection or plant control functions that utilize inputs from core exit thermocouples (CETs); there is no operational necessity for more accurate measurement of temperatures throughout the core; the petition provided inadequate justification of why precise knowledge of core temperature at various elevations and radial positions would enhance safety or change operator action; and the NRC believes that, despite the known limitations of CETs, CETs are sufficient to allow NPP operators to take timely and effective action in the event of an accident.
Agency Information Collection Activities: Proposed Collection; Comment Request
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: NRC Form 314, Certificate of Disposition of Materials. 2. Current OMB approval number: 3150-0028. 3. How often the collection is required: This form is submitted once, when a licensee terminates its license. 4. Who is required or asked to report: Persons holding an NRC license for the possession and use of radioactive byproduct, source, or special nuclear material who are ceasing licensed activities and terminating the license. 5. The number of annual respondents: 136. 6. The number of hours needed annually to complete the requirement or request: 68. 7. Abstract: The NRC Form 314 furnishes information to the NRC regarding transfer or other disposition of radioactive material by licensees who wish to terminate their licenses. The information is used by the NRC as part of the basis for its determination that the facility has been cleared of radioactive material before the facility is released for unrestricted use. Submit, by November 12, 2013, 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. The OMB clearance requests are available at the NRC's Web site: https://www.nrc.gov/public-involve/doc- comment/omb/. The document will be available on the NRC's home page site for 60 days after the signature date of this notice. Comments submitted in writing or in electronic form will be made available for public inspection. Because your comments will not be edited to remove any identifying or contact information, the NRC cautions you against including any information in your submission that you do not want to be publicly disclosed. Comments submitted should reference Docket No. NRC- 2013-0206. You may submit your comments by any of the following methods: Electronic comments go to: https://www.regulations.gov and search for Docket No. NRC-2013-0206. Mail comments to NRC Clearance Officer, Tremaine Donnell (T-5 F53), U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001. Questions about the information collection requirements may be directed to the NRC Clearance Officer, Tremaine Donnell (T-5 F53), U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, by telephone at 301-415-6258, or by email to INFOCOLLECTS.Resource@NRC.GOV.
