Nuclear Regulatory Commission July 7, 2017 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is amending its spent fuel storage regulations by revising the EnergySolutionsTM Corporation's (EnergySolutions or the applicant) VSC-24 Ventilated Storage Cask System listing within the ``List of Approved Spent Fuel Storage Casks'' to renew, for an additional 40 years, the initial certificate and Amendment Nos. 1-6 of Certificate of Compliance (CoC) No. 1007. The renewal of the initial certificate and Amendment Nos. 1-6 requires cask users to establish, implement, and maintain written procedures for aging management program (AMP) elements, including a lead cask inspection program, for VSC-24 Storage Cask structures, systems, and components (SSCs) important to safety. Users must also conduct periodic ``tollgate'' assessments of new information on SSC aging effects and mechanisms to determine whether any element of an AMP addressing these effects and mechanisms requires revision to encompass the current state of knowledge. In addition, the renewal of the initial certificate and Amendment Nos. 1-6 makes several other changes, described in Section IV, ``Discussion of Changes,'' in the SUPPLEMENTARY INFORMATION section of the companion direct final rule published in the Rules and Regulations section of this issue of the Federal Register.
