NRC Issues RIS re Decommissioning Timeliness Rule Implementation and Associated Regulatory Relief

On December 21, 2015, the U.S. Nuclear Regulatory Commission (NRC) issued Regulatory Issue Summary (RIS) 2015-19 titled, “Decommissioning Timeliness Rule Implementation and Associated Regulatory Relief.”

RIS 2015-19 was distributed to all holders of and applicants for NRC licenses under Title 10 of the Code of Federal Regulations (10 CFR) Part 30, “Rules of General Applicability to Domestic Licensing of Byproduct Material;” 10 CFR Part 40, “Domestic Licensing of Source Material;” 10 CFR Part 70, “Domestic Licensing of Special Nuclear Material;” and,

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.” The notice was also distributed to Agreement State Radiation Control Program Directors and State Liaison Officers.

According to the document, NRC issued RIS 2015-19 in order to:

  1. provide clarity on the Decommissioning Timeliness Rule’s (DTR’s) requirements to notify the NRC to begin and complete decommissioning after certain criteria are met;
  1. highlight opportunities for licensees to request alternatives to the DTR’s requirements;
  1. remind licensees that there are situations where they can request an alternative to the DTR’s timeliness requirements for both beginning and completing decommissioning if adequately justified;
  1. clarify when the DTR applies to licensees whose only location of use are temporary jobsites; and,
  1. clarify when the NRC considers that the licensee has transitioned from an “operational” to a “decommissioning” status.

RIS 2015-19 requires no action or written response beyond that already required by regulations. The NRC provided RIS 2015-19 to the Agreement States for their information and for distribution to their licensees, as appropriate. However, a notice of opportunity for public comment on RIS 2015-19 was not published in the Federal Register because the RIS is intended to be informational and is not intended to represent a departure from current regulatory requirements.
