Nuclear Regulatory Commission February 28, 2017 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is withdrawing Regulatory Guide (RG) 5.18, ``Limit of Error Concepts and Principles of Calculation in Nuclear Materials Control.'' This RG is being withdrawn because the term ``limit of error'' is no longer used in the material control and accounting (MC&A) requirements in NRC's regulations, and therefore the RG 5.18 guidance is no longer needed. The MC&A requirements now include the term ``standard error'' in place of the term ``limit of error.'' The ``standard error'' term is used in evaluating the significance of an inventory difference (ID). The NRC has issued guidance separately for the term ``standard error.''

Pursuant to Section 189a. (2) of the Atomic Energy Act of 1954, as amended (the Act), the U.S. Nuclear Regulatory Commission (NRC) is publishing this regular biweekly notice. The Act requires the Commission to publish notice of any amendments issued, or proposed to be issued, and grants the Commission the authority to issue and make immediately effective any amendment to an operating license or combined license, as applicable, upon a determination by the Commission that such amendment involves no significant hazards consideration, notwithstanding the pendency before the Commission of a request for a hearing from any person. This biweekly notice includes all notices of amendments issued, or proposed to be issued, from January 31, 2017 to February 13, 2017. The last biweekly notice was published on February 14, 2017.
