NRC Tinkers with Nuclear Waste Casks in Endless Amendment Loop
Published Date: 8/26/2026
Rule
Summary
The U.S. Nuclear Regulatory Commission (NRC) is amending its spent fuel storage 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 Amendment No. 19 to Certificate of Compliance (CoC) No. 1004. Amendment No. 19 revises 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 will simplify construction, reduce weight and improve fabricability. Additional changes are proposed to address editorial corrections, consistency, and terminology clarifications. 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.

The Office of Personnel Management (OPM) is amending its regulations governing the critical position pay (CPP) authority to establish level I of the Executive Schedule as the default maximum critical pay rate, with higher rates subject to written approval by the Director of OPM. The final rule eliminates non-statutory caps and approval criteria; addresses the use of service agreements; clarifies that reductions or terminations of CPP are not adverse actions or subject to grievance or appeal rights; and clarifies the treatment of critical pay rates as basic pay. This final rule simplifies and better aligns OPM's regulations with governing law and delegated authority.

On September 1, 2023, Florida submitted to the Environmental Protection Agency (EPA) a program revision application seeking authorization of changes to its hazardous waste program under the Resource Conservation and Recovery Act (RCRA), as amended. On March 26, 2026, the EPA published both a direct final action granting Florida final authorization for revisions to its federally authorized hazardous waste program, along with a companion proposed rule announcing the EPA's proposal to grant such final authorization. The EPA announced in both documents that the direct final action would become effective on May 26, 2026, unless adverse comments were received by April 27, 2026. Although the EPA received two comments during the public comment period, the EPA determined that the comments were not adverse. As a result, the direct final rule became effective on May 26, 2026. This action responds to the comments the EPA received.
