Nuclear Regulatory Commission April 17, 2015 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is issuing an exemption in response to a December 31, 2014, letter from UniStar Nuclear Energy (UNE), on behalf of Calvert Cliffs Nuclear Project, LLC, and UniStar Operating Services, LLC, co-applicants for the combined license (COL) application for the Calvert Cliffs Nuclear Power Plant Unit 3 (CCNPP3), which requested an exemption to delay the submission of the annual update of the Final Safety Analysis Report (FSAR) to be included in their COL application. The NRC staff reviewed this request and determined that it is appropriate to grant the exemption to delay the FSAR update submittal up to December 31, 2015.

The U.S. Nuclear Regulatory Commission (NRC) is providing supplemental information to an earlier notice, appearing in the Federal Register on March 4, 2015, which requested comment on a draft interim staff guidance (ISG), ``Guidance for Evaluation of Acute Chemical Exposures and Proposed Quantitative Standards.'' The draft ISG, if issued in final form, would supplement existing guidance in NUREG-1520, ``Standard Review Plan for the Review of a License Application for a Fuel Cycle Facility,'' by providing additional guidance and the descriptions of proposed quantitative standards for the NRC to follow when evaluating the integrated safety analysis (ISAs) of acute chemical exposures. This action is necessary to provide the public with the backfitting information with respect to the draft ISG, and includes references to the key documents on backfitting issues. The public comment period was originally scheduled to close on May 18, 2015. The NRC is extending the public comment period on this action to allow more time for members of the public to review the additional information on backfitting before submitting any comments.
