{"abstract":"The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its spent fuel storage regulations by revising the NAC International NAC-UMS[supreg] listing within the \"List of approved spent fuel storage casks\" to include Amendment No. 6 to Certificate of Compliance (CoC) No. 1015. Amendment No. 6 revises the CoC's technical specifications (TSs) to: Remove a redundant requirement for inspection of the concrete cask and canister; revise a limiting condition of operation (LCO) for heat removal to clarify that \"LCO not met\" means that the concrete heat removal system is inoperable; remove an inspection requirement that is already covered by LCO surveillance requirements for off-normal, accident, or natural phenomenon events; and clarify that \"immediate\" restoration of a concrete cask's heat removal capabilities means \"within the design-basis time limit\" in Section 11.2.13 of the Final Safety Analysis Report (FSAR), \"or within the time limit for a less than design-basis heat load case, as evaluated.\" Amendment No. 6 also clarifies that an LCO for loaded cask surface dose rates applies prior to storage conditions, when dose rates will be highest.","action":"Proposed rule.","agencies":[{"raw_name":"NUCLEAR REGULATORY COMMISSION","name":"Nuclear Regulatory Commission","id":383,"url":"https://www.federalregister.gov/agencies/nuclear-regulatory-commission","json_url":"https://www.federalregister.gov/api/v1/agencies/383","parent_id":null,"slug":"nuclear-regulatory-commission"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2018/10/22/2018-22913.html","cfr_references":[{"chapter":null,"citation_url":null,"part":72,"title":10}],"citation":"83 FR 53191","comment_url":null,"comments_close_on":"2018-11-21","correction_of":null,"corrections":["https://www.federalregister.gov/api/v1/documents/C1-2018-22913"],"dates":"Submit comments by November 21, 2018.
