Discussion The NRC is issuing draft NUREG/CR ‘‘Spent Fuel Transportation Package Response to the MacArthur Maze Fire Scenario.’’ This report presents analyses that were performed to examine the hypothetical effects on a spent fuel transportation package from conditions during the MacArthur Maze accident in 2007. The analyses undertaken include FDS fire modeling, physical examination of material samples, ANSYS and COBRA–SFS code thermal modeling of a GA–4 package, ANSYS and LS–DYNA structural and thermalstructural modeling of the roadway and package, and fuel performance modeling using the FRAPTRAN–1.4, FRAPCON– 3.4, and DATING codes. The estimated release from the hypothetical scenario is below the prescribed limit for safety. The purpose of this notice is to provide the public with an opportunity to review and provide comments on draft NUREG/CR–7206, ‘‘Spent Fuel Transportation Package Response to the MacArthur Maze Fire Scenario’’. Any comments received will be considered in the final version or subsequent revisions of the draft NUREG/CR. Dated at Rockville, Maryland, this 17th day of December, 2015.

Jkt 238001 BILLING CODE 7590–01–P NUCLEAR REGULATORY COMMISSION [NRC–2015–0285] Containment Shell or Liner Moisture Barrier Inspection Nuclear Regulatory Commission. ACTION: Draft regulatory issue summary; request for comment. AGENCY: The U.S. Nuclear Regulatory Commission (NRC) is seeking public comment on a draft regulatory issue summary (RIS) to reiterate the NRC staff’s position in regard to American Society of Mechanical Engineers (ASME) code-required inservice inspection requirements for moisture barriers. The NRC’s regulations require, in part, that licensees implement the inservice inspection program for pressure retaining components and their integral attachments of metal containments and metallic liners of concrete containments in accordance with the ASME Code. If a material prevents moisture from contacting inaccessible areas of the containment shell or liner, especially if the material is being relied upon in lieu of augmented examinations of a susceptible location, the material must be inspected as a moisture barrier. The applicable ASME Code sections require licensees to inspect 100 percent of accessible moisture barriers during each inspection period. DATES: Submit comments by January 25, 2016. Comments received after this date will be considered if it is practical to do so, but the Commission is able to ensure consideration only for comments received before this date. ADDRESSES: You may submit comments by any of the following methods (unless this document describes a different method for submitting comments on a specific subject): • Federal Rulemaking Web site: Go to https://www.regulations.gov and search for Docket ID NRC–2015–0285.

II. Background The NRC issues RISs to communicate with stakeholders on a broad range of regulatory matters. This may include communicating staff technical positions on matters that have not been communicated to or are not broadly understood by the nuclear industry. The NRC staff has developed draft RIS 20YY–XX, ‘‘Containment Shell or Liner Moisture Barrier Inspection,’’ to reiterate NRC expectations for these inspections. The NRC staff has identified several instances in which containment shell or liner moisture barrier materials were not properly inspected in accordance with ASME Code Section XI, Table IWE–2500–1, Item E1.30. Note 4 (Note 3 in editions before 2013) for Item E1.30 under the ‘‘Parts Examined’’ column states, ‘‘Examination shall include moisture barrier materials intended to prevent intrusion of moisture against inaccessible areas of the pressure retaining metal containment shell or liner at concrete to metal interfaces and at metal to metal interfaces which are not seal welded. Containment moisture barrier materials include caulking, flashing, and other sealants used for this application.’’ Examples of inadequate inspections have included licensees not identifying sealant materials at metal-tometal interfaces as moisture barriers because they are not specifically depicted in Figure IWE–2500–1, and licensees not inspecting installed moisture barrier materials per Item E1.30 because the material was not included in the original design or was not identified as a ‘‘moisture barrier’’ in the design documents. The NRC staff expects licensees to inspect 100 percent of accessible moisture barriers during each inspection period, in accordance with Table IWE– 2500–1, Item E1.30, as required by § 50.55a of title 10 of the Code of Federal Regulations (10 CFR). Items VerDate Sep<11>2014 17:57 Dec 23, 2015 Jkt 238001 within the scope of E1.30 inspections shall be identified based on the function of the item as described in the Table IWE–2500 1 note. As noted previously, Figure IWE 2500 1 represents one typical moisture barrier geometry; however, it is not comprehensive. If a material prevents moisture from contacting inaccessible areas of the containment shell or liner, especially if the material is being relied upon in lieu of augmented examinations of a susceptible location per IWE–1241, the material shall be inspected as a moisture barrier, as also described in Information Notice 2014–07 (ADAMS Accession No. ML14070A114). Furthermore, if the Item E1.11 and Item E1.30 inspections are addressed in the same procedures, the inspection scope and acceptance criteria should identify the different surfaces. Items E1.11 and E1.30 address different materials with different geometries and acceptance criteria. Proposed Action The NRC is requesting public comments on the draft RIS. The NRC staff will make a final determination regarding issuance of the RIS after it considers any public comments received in response to this request.

II. Background

    The NRC issues RISs to communicate with stakeholders on a broad 
range of regulatory matters. This may include communicating staff 
technical positions on matters that have not been communicated to or 
are not broadly understood by the nuclear industry. The NRC staff has 
developed draft RIS 20YY-XX, ``Containment Shell or Liner Moisture 
Barrier Inspection,'' to reiterate NRC expectations for these 
inspections. The NRC staff has identified several instances in which 
containment shell or liner moisture barrier materials were not properly 
inspected in accordance with ASME Code Section XI, Table IWE-2500-1, 
Item E1.30. Note 4 (Note 3 in editions before 2013) for Item E1.30 
under the ``Parts Examined'' column states, ``Examination shall include 
moisture barrier materials intended to prevent intrusion of moisture 
against inaccessible areas of the pressure retaining metal containment 
shell or liner at concrete to metal interfaces and at metal to metal 
interfaces which are not seal welded. Containment moisture barrier

licensees not identifying sealant materials at metal-to-metal

    The NRC staff expects licensees to inspect 100 percent of

accordance with Table IWE-2500-1, Item E1.30, as required by Sec.  
50.55a of title 10 of the Code of Federal Regulations (10 CFR). Items 
within the scope of E1.30 inspections shall be identified based on the

should identify the different surfaces. Items E1.11 and E1.30 address 
different materials with different geometries and acceptance criteria.
Proposed Action
    The NRC is requesting public comments on the draft RIS. The NRC 
staff will make a final determination regarding issuance of the RIS 
after it considers any public comments received in response to this 
request.
