INTRODUCTIONThis regulatory guide has been compiled by the United States Nuclear Regulatory Commission (NRC)as an aidin the preparation of applications for approval of packaging to be used for the shipment oftype B, largequantity, and fissile radioactive material.It is not intended as an interpretation of Commission regulations,within the meaning of §§ 30.5, 40.6, 70.6, or 71.14, Parts 30, 40, 70, or 71, respectively, ofTitle 10 of theCode of Fede-al Regulations. Nothing contained in this guide may be construed as having theforce and effect ofNRC regulations, nor as indicating that applications supported by safety analyses and preparedin accordance withthe recommendations of this regulatory guide necessarily will be approved, nor as relievingany licensee fromthe requirements of 10 CFR Parts 30, 40, 70, and 71,* and any other pertinent regulations.This regulatory guide should not be considered a substitute for reference to 10 CFR Part 71,"Packaging ofRadioactive Material for Transport and Transportation of Radioactive Material Under CertainConditions." Itsprimary purpose is to assist the applicant in preparing an application that thoroughly and completelydemonstratesthe adequacy of the package in meeting the regulations. In addition to an approval of packaging,the applicantmust have an approved quality assurance program in accordance with the provisions of § 71.51of 10 CFR. Additional information will be requested in support of an application if NRC believes that such informationis necessary to provide reasonable assurance of the safety of the proposed shipment. In preparing anapplication forapproval of packaging, the applicant may find it useful to refer to other regulatory guides ofDivision 7, "Transportation." Inquiries about these regulatory guides may be directed to the U.S. Nuclear RegulatoryCommission,Washington, D.C. 20555, Attention: Director, Division of Technical Information and Document Control.Purpose of Standard FormatThe purpose of the Standard Format and Content of Part 71 Applications for Approval of Packagingof Type B,Large Quantity, and Fissile Radioactive Material (hereinafter "Standard Format") is to indicatethe informationto be provided in the application and to establish a uniform format for presenting the information.Use of thisformat will help ensure the completeness of the information provided, will assist the NRC staffand others inlocating the information, and will aid in shortening the time needed for the review process.The application isthe principal document in which the applicant provides the information and bases for the NRC staffto determinewhether or not the package meets the reauirements of 10 CFR Part 71.Applicability of Standard FormatThis Standard Format applies specifically to applications for approval of packaging of type B, largequantity,and fissile radioactive material under 10 CFR Part 71. The Standard Format identifies generaland detailedinformation required and will help ensure the completeness of the information provided.The NRC staff is currently revising 10 CFR Part 71 to incorporate the IAEA-1973 revisions. Theproposed rulej**has been published in the Federal Register (44 FR 48234) on August 17, 1979.This format guide does not attemptjto incorporate possible changes to Part 71. As Part 71 is revised, this format guide will beappropriatelymodified.Lines indicate substantive changes from previous issue.
Use of Standard FormatThe Standard Format presents a format for applications for approval that is acceptable to the NRC staff.Conformance with the Standard Format, however, is not required. Applications for approval with different formatswill be acceptable to the staff if they provide an adequate basis for the findings requisite to the approvalofpackaging. However, because it may be more difficult to locate needed information, the staff review time forsuch applications may be longer.Upon receipt of an application, the NRC staff will perform a preliminary review to determine if the application provides a reasonably complete presentation of the information that is needed to form a basis for thefindings required before approval of a package in accordance with 10 CFR Part 71. The Standard Format will beused by the staff as a guideline to identify the type of information needed. If the application does notprovide a reasonably complete presentation of the necessary information, further review of the application will notbe initiated until a reasonably complete presentation is provided. The information provided in the applicationshould be up to date with respect to the state of technology for transportation of radioactive materialsandshould take into account recent changes in NRC regulations and guides, industry codes and standards, resultsofrecent developments in transportation safety, and experience in the construction and use of radioactive materialpackaging.Style and CompositionThe applicant should strive for clear, concise presentations of the information provided in the applicaConfusing or ambiguous statements and unnecessarily verbose descriptions do not contribute to expeditioustechnical review. Claims of adequacy of designs or design methods should be supported by technical bases, i.e.,by an appropriate engineering evaluation or description of actual tests. Terms as defined in the packaging andtion.transport regulations must be used.The application should follow the numbering system and headings of the Standard Format at least to theheadings with three digits, e.g., 2.4.2 Positive Closure. When a particular requirement does not apply toapackage, the corresponding subsection should not be omitted but addressed with the term "Not Applicable." Areason should be offered for not addressing a particular requirement when there is doubt as to its applicability.Appendices to each chapter of the applicationfor clarity. A list of reports or other documentsincluded in the appendix at the end of the chapterenced, page numbers should be provided. In casesshould include detailed information omitted from the main textthat are referenced in the text of the application should bein which they are referenced. When specific items are referwhere proprietary documents are referenced, a nooproprietarysummary description of the document should also be referenced.All physical tests of components and packages should be supported by photographs in the appendices of theappropriate chapter. Appendices to the application may also be used to provide supplemental information notexplicitly identified in the Standard Format.Examples of such information are (1) summaries of the manner inwhich the applicant has treated matters addressed in NRC regulatory guides and (2) supplementaryinformationregarding calculational methods or design approaches used by the applicant or its agents.Where numerical values are stated, the number of significant figures given should reflect the accuracyorprecision to which the number is known.Where possible, estimated limits of error or uncertainty should begiven.Significant figures should not be dropped or rounded off if, by doing so, subsequent conclusionsareinadequately supported.ii
Abbreviations should be consistent throughout the application and should be consistent with generallyaccepted usage. Any abbreviations, symbols, or special terms unique tothe proposed packaging or not in generalusage should be defined In each chapter of the application where they areused.Drawings, diagrams, sketches, and charts should be used where theinformation can be presented more adequately or conveniently by such means. Due concern should be takento ensure that all information presented indrawings is legible, symbols are defined, and drawings are notreduced to the extent that visual aids are necessary to interpret pertinent items of information presented in thedrawings.RevisionsData and text should be updated or revised by replacing pages.should n be used."Pen and ink" or "cut and paste" changesThe changed or revised portion on each page should be highlightedby a "change indicator" mark consistingof a bold vertical line drawn in the margin opposite the bindingmargin. The line should be the sam length asthe portion actually changed.All pages submitted to update, revise, or add pages to the reportshould show the date of change and a changeor amendment number. A transmittal letter, including a guide pagelisting the pages to be inserted and the pagesto be removed, should accompany the revised pages. Where applicable,supplemental pages may follow the revisedpage.All statements on a revised page should be accurate as of the dateof the submittals.Special care should be taken to ensure that the main sections ofthe report are revised to reflect any designchanges reported in supplemental information, i.e., responses toNRC staff requests for information or responsesto regulatory positions.Physical SpecificationsAll material submitted as part of the application should conformto specific standards as to the physicaldimensions of page size, quality of paper and inks, and numberingof pages, exhibits, and attachments.

The containment vessel should be clearly identified. Overall and cutaway sketches(8-1/2 x 11 inches) ofthe package should be included as part of the description.Drawings that clearly suimmarize the safety features considered in the analysis should beincluded in Appendix 1.3; e.g., material lists, dimensions, valves, gaskets, and weld specifications shouldbe included on thedrawings. Detailed construction drawings of large, complex packages should not be included.1.2.2 Operational FeaturesIn the case of a complex package system, a discussion of the operation of the package shouldbe provided.This would include a schematic diagram showing all valves, connections, piping, openings,seals, containmentboundaries, etc.1.2.3 Contents of PackagingState the quantity of radionuclides (in the case of irradiated fuel shipments, also estimatethe quantityof radionuclides available for immediate release within the void space of the fuel rods), chemicaland physicalform, material density, moderator ratios, configurations as required for nuclear safety evaluation,the maximumamount of decay heat, maximum pressure buildup in the inner container, and any other loadingrestrictions.1.3AppendixThis appendix should include detailed information describing the packaging, operational features,and contents of the packaging such as dimensional drawings, detailed operational schematics, and loadingconfigurations.1-1
2.STRUCTURAL EVALUATIONThis chapter of the application should identify, describe, discuss, and analyze the principal structuralengineering design of the packaging, components, and systems important to safety and to compliance with theperformance requirements of 10 CFR Part 71.2.1Structural Design2.1.1 DiscussionIdentify the principal structural members and systems such as the containment vessel, impact limiters,closure devices, and valves that are vital to safe operation of the package. Reference the location of theseitems on drawings, and discuss their structural design and performance.2.1.2 Design CriteriaDescribe the load combinations and factors that serve as design criteria. Design criteria may be used ifjudged acceptable by the NRC staff in meeting the structural requirements of if 71.35 and 71.36 of 10 CFR Part 71.For each of these criteria, state the maximum allowable stresses and strains (as a percentage of the yield orultimate values) for ductile failure; describe how the other structural failure modes (e.g., brittle fracture,fatigue, buckling) are considered. If different design criteria are to be allowed in various parts of the packaging or for different conditions, the appropriate values for each case should be indicated. Include the criteriathat will be used for impact evaluation. Identify all codes and standards that are used to determine materialproperties, design limits, or methods of combining loads and stresses. In cases of deviation from standard codes,or if certain components are not covered by such codes, provide a detailed description of the design criteriaused as substitutes.2.2Weights and Centers of GravityList the total weight of the packaging and contents. Tabulate the weights of major individual subassembliessuch that the sum of the parts equals the total of the package.
