Robert H. Leyse; Denial of Petition for Rulemaking
The Nuclear Regulatory Commission (NRC) is denying a petition for rulemaking submitted by Mr. Robert H. Leyse (PRM-50-76). The petitioner requests that the NRC's regulations concerning the specified evaluation models for emergency core cooling systems (ECCS) and associated guidance documents be amended. The petitioner asserts that amendments are necessary to correct technical deficiencies in the correlations and data used for calculation of metal-water oxidation. The petitioner states that the correlations and data do not consider the complex thermal-hydraulic conditions present during a loss-of- coolant accident (LOCA), including the potential for very high fluid temperature. The Commission is denying Mr. Leyse's petition for rulemaking (PRM-50-76). None of the specific technical issues raised by the petitioner have shown safety-significant deficiencies in the research, calculation methods, or data used to support ECCS performance evaluations. NRC's technical safety analysis demonstrates that current procedures for evaluating ECCS performance are based on sound science and that no amendments to the NRC's regulations and guidance documents are necessary.
Licenses, Certifications, and Approvals for Nuclear Power Plants
The Nuclear Regulatory Commission (NRC) is making available the draft wording of a proposed amendment of its regulations. The proposal would amend Title 10 of the Code of Federal Regulations (10 CFR) part 52, ``Early Site Permits; Standard Design Certifications; and Combined Licenses for Nuclear Power Plants,'' and associated regulations based on experience gained from early site permit (ESP) and design certification reviews and discussions with stakeholders on the ESP and combined license (COL) processes. The changes should improve the effectiveness and efficiency of the licensing processes for future applicants. The availability of the draft rule language is intended to inform stakeholders of the current status of the NRC staff's activities to amend 10 CFR part 52. Publicly available documents related to this rulemaking may be viewed electronically on the public computers located at the NRC's Public Document Room (PDR), O1 F21, One White Flint North, 11555 Rockville Pike, Rockville, Maryland. The PDR reproduction contractor will copy documents for a fee. Selected documents can be viewed and downloaded electronically via the NRC rulemaking Web site at http:// ruleforum.llnl.gov. Publicly available documents created or received at the NRC after November 1, 1999, are available electronically at the NRC's Electronic Reading Room at http://www.nrc.gov/NRC/ADAMS/index.html. From this site, the public can gain entry into the NRC's Agencywide Document Access and Management System (ADAMS), which provides text and image files of NRC's public documents. If you do not have access to ADAMS or if there are problems in accessing the documents located in ADAMS, contact the NRC PDR Reference staff at 1-800-397-4209, 301-415-4737, or by e-mail to firstname.lastname@example.org.
