In Situ Recovery Monitoring and Decommissioning Timeliness

The U.S. Nuclear Regulatory Commission (NRC) proposes to amend its regulations that govern the licensing of uranium mills and the disposition of tailings and waste that arise from the extraction and milling of uranium by issuing risk-informed requirements for groundwater protection at uranium in situ recovery (ISR) facilities. The NRC's current regulations are focused on conventional uranium milling and do not expressly address uranium extraction by the ISR process. Additionally, NRC proposes to amend its regulations that govern decommissioning timeliness for all licensees to provide additional flexibility for licensees to delay the initiation of decommissioning activities in situations where safety would not be impacted.

List of Approved Spent Fuel Storage Casks: TN Americas, LLC Standardized NUHOMS® Horizontal Modular Storage System for Irradiated Nuclear Fuel, Certificate of Compliance No. 1004, Renewed Amendment No. 19

The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its spent fuel regulations by revising the TN Americas, LLC Standardized NUHOMS[supreg] Horizontal Modular Storage System for Irradiated Nuclear Fuel listing within the "List of approved spent fuel storage casks" to include Renewed Amendment No. 19 to Certificate of Compliance (CoC) No. 1004. The NRC is referring to this amendment as "Renewed Amendment No. 19" because it was submitted after the renewal of the TN Americas, LLC Standardized NUHOMS Horizontal Modular Storage System for Irradiated Nuclear Fuel Certificate of Compliance No. 1004 and, therefore, subject to the Aging Management Program requirements of the renewed certificate. Renewed Amendment No. 19 would amend the certificate of compliance to provide for a 61BTH improved basket design using staggered plates similar the 24PTH Type 3 basket approved in CoC 1004 Amendment 18 and similar to the EOS 37PTH and 89BTH baskets approved in CoC 1042. This would simplify construction, reduce weight and improve fabricability. Additional changes are proposed to address editorial corrections, consistency, and terminology clarifications.
