(Draft was issued as DG-1090)
DESIGN, FABRICATION, AND MATERIALS CODE CASE
ACCEPTABILITY, ASME SECTION III
A. INTRODUCTION
General Design Criterion (GDC) 1, “Quality Standards and Records,“ of Appendix A,
“General Design Criteria for Nuclear Power Plants,” to 10 CFR Part 50, “Domestic Licensing ofProduction and Utilization Facilities,” requires, in part, that structures, systems, and componentsimportant to safety be designed, fabricated, erected, and tested to quality standards
commensurate with the importance of the safety function to be performed. Where generallyrecognized codes and standards are used, Criterion 1 requires that they be identified andevaluated to determine their applicability, adequacy, and sufficiency and be supplemented ormodified as necessary to ensure a quality product in keeping with the required safety function.Criterion 30, “Quality of Reactor Coolant Pressure Boundary,” of Appendix A requires, in
part, that components that are part of the reactor coolant pressure boundary be designed,fabricated, erected, and tested to the highest quality standards practical.
Appendix B, “Quality Assurance Criteria for Nuclear Power Plants and Fuel Processing
Plants,” to 10 CFR Part 50 requires, in part, that measures be established for the control ofspecial processing of materials and that proper testing be performed.
Provisions of the American Society of Mechanical Engineers (ASME) Boiler and Pressure
Vessel (BPV) Code have been used since 1971 as one part of the framework to establish thenecessary design, fabrication, construction, testing, and performance requirements for
structures, systems, and components important to safety. ASME standards committees develop,among other things, improved methods for the construction and inservice inspection (ISI) ofASME Class 1, 2, 3, MC (metal containment) and CC (concrete containment) nuclear power
Regulatory guides are issued to describe and make available to the public such information as methods acceptable to the NRC staff for implementing specific parts of theNRC’s regulations, techniques used by the staff in evaluating specific problems or postulated accidents, and data needed by the NRC staff in its review of applicationsfor permits and licenses. Regulatory guides are not substitutes for regulations, and compliance with them is not required. Methods and solutions different from those setout in the guides will be acceptable if they provide a basis for the findings requisite to the issuance or continuance of a permit or license by the Commission.
This guide was issued after consideration of comments received from the public. Comments and suggestions for improvements in these guides are encouraged at all times,and guides will be revised, as appropriate, to accommodate comments and to reflect new information or experience. Written comments may be submitted to the Rulesand Directives Branch, ADM, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001.
Regulatory guides are issued in ten broad divisions: 1, Power Reactors; 2, Research and Test Reactors; 3, Fuels and Materials Facilities; 4, Environmental and Siting;5, Materials and Plant Protection; 6, Products; 7, Transportation; 8, Occupational Health; 9, Antitrust and Financial Review; and 10, General.
Single copies of regulatory guides (which may be reproduced) may be obtained free of charge by writing the Distribution Services Section, U.S. Nuclear RegulatoryCommission, Washington, DC 20555-0001, or by fax to (301)415-2289, or by email to DISTRIBUTION@NRC.GOV. Electronic copies of this guide and other recently issuedguides are available at NRC’s home page at plant components. A broad spectrum of stakeholders participate in the ASME process,which helps to ensure that the various interests are considered. The regulation in 10 CFR 50.55a(c), “Reactor Coolant Pressure Boundary,” requires, in part, that components of the reactor coolant pressure boundary be designed,fabricated, erected, and tested in accordance with the requirements for Class 1components of Section III, “Rules for Construction of Nuclear Power Plant Components,”1 of the ASME BPV Code or equivalent quality standards. The ASMEpublishes a new edition of the BPV Code, which includes Section III, every 3 years, andnew addenda every year. The latest editions and addenda of Section III that have beenapproved for use by the NRC are referenced in 10 CFR 50.55a(b). The ASME alsopublishes Code Cases quarterly. Code Cases provide alternatives developed and approved by ASME or explain the intent of existing Code requirements. This regulatoryguide identifies the Code Cases that have been determined by the NRC to be acceptable alternatives to applicable parts of Section III. Section III Code Cases not yetendorsed by the NRC may be implemented through 10 CFR 50.55a(a)(3), which permitsthe use of alternatives to the Code requirements referenced in 10 CFR 50.55a providedthat the proposed alternatives result in an acceptable level of quality and safety, andtheir use is authorized by the Director of the Office of Nuclear Reactor Regulation.The ASME Code is incorporated by reference into 10 CFR 50.55a. Code Cases approved by the NRC provide an acceptable voluntary alternative to the mandatoryASME Code provisions. Therefore, 10 CFR 50.55a has been amended to incorporatethis guide by reference and it states the requirements governing the use of Code Cases. Because of the continuing change in the status of Code Cases, periodic updates to 10CFR 50.55a and this guide are planned to accommodate new Code Cases and anyrevisions of existing Code Cases. This regulatory guide does not contain a new or amended information collection requirement subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing requirements were approved by the Office of Management and Budget, and theapproval number is 3150-0011. If a means used to impose an information collectiondoes not display a currently valid OMB control number, the NRC may not conduct orsponsor, and a person is not required to respond to, the information collection. B. DISCUSSION Previously, Regulatory Guide 1.84 was titled “Design and Fabrication Code Case Acceptability, ASME Section III, Division 1,” and it listed only the Section III Code Casesoriented to design and fabrication. Companion Regulatory Guide 1.85, “Materials CodeCase Acceptability, ASME Section III, Division 1,” listed the Section III Code Cases oriented to materials and testing. Beginning with this revision, all Section III Code Casesthat have been approved for use by the NRC are listed in this guide. Hence, the title ofRegulatory Guide 1.84 has been changed to “Design, Fabrication, and Materials CodeCase Acceptability, ASME Section III.” It should be noted that with this Revision 32,Division 1 has been deleted from the title. Previous versions of the guide containedsome Division 2 Code Cases, and this version contains some Division 3 Code Cases. 1 Copies may be obtained from the American Society of Mechanical Engineers, Three Park Avenue, New York, NY 10016-5990. Phone (212)591-8500; fax (212)591-8501; www.asme.org. 2 Hence, the title change reflects the revised scope of Regulatory Guide 1.84. RegulatoryGuide 1.85 will no longer be updated, but it will be withdrawn in the future. For Revision 32 to Regulatory Guide 1.84, the NRC staff reviewed the Section III Code Cases listed in Supplement 4 to the 1992 Edition through Supplement 11 to the1998 Edition.2 Appendix A to the guide lists the supplements reviewed, the edition, andthe Board on Nuclear Codes and Standards approval date. Appendix B is a numericallist of the Code Cases addressed in these supplements. The Code Cases are listed infive tables: Table 1, “Acceptable Section III Code Cases,” contains the Code Cases thatare acceptable to the NRC for application in the design and construction of light-water-cooled nuclear power plants; Table 2, “Conditionally Acceptable Section III Code Cases,” contains Code Cases that are acceptable provided that they are used with theidentified limitations or modifications, i.e., the Code Case is generally acceptable but theNRC has determined that the alternative requirements must be supplemented in order toprovide an acceptable level of quality and safety; Table 3, “Annulled Unconditionally Approved Section III Code Cases,” contains the Code Cases that have been annulled bythe ASME; Table 4, “Annulled Conditionally Acceptable Section III Code Cases,” contains the Code Cases that the NRC determined to be acceptable provided that theyare used with the identified limitations or modifications, but were subsequently annulledby the ASME; Table 5, “Section III Code Cases That Have Been Superseded byRevised Code Cases on or After July 1, 1974,” lists Code Cases that have been superseded through revision. Code Cases that the NRC determined to be unacceptableare listed in a new regulatory guide, “ASME Code Cases Not Approved for Use” (draftwas issued as DG-1112; final guide issued as Regulatory Guide 1.193). It should benoted that Tables 1-5 provide comprehensive lists of Section III Code Cases since manyolder Code Cases are still in use, i.e., Section III, Division 1, applies only to new construction (the edition and addenda used in the construction of a plant were selectedbased upon the date of the construction permit and are not changed thereafter, exceptvoluntarily by the licensee). Code Cases provide alternatives that were developed and approved by ASME to existing Code requirements. The Code Cases listed as approved in Tables 1 and 2 ofthis guide have been incorporated by reference into 10 CFR 50.55a. The Code Casesmay be used voluntarily by licensees as an alternative to compliance with ASME Codeprovisions that have been incorporated by reference into 10 CFR 50.55a. Requirements related to implementation of Code Cases are provided in 10 CFR 50.55a(b). When a licensee initially applies a Code Case listed in Table 1 or 2,the licensee must implement the most recent version of that Code Case incorporated byreference in 10 CFR 50.55a. Code Cases may expire or be annulled because the provisions have been incorporated into the Code, the application for which it was specifically developed nolonger exists, or experience has shown that the design analysis or construction methodis no longer adequate. After a Code Case is annulled and 10 CFR 50.55a and this guideare amended, licensees may not implement that Code Case for the first time. However,a licensee who implemented the Code Case prior to annulment may continue to use thatCode Case until the licensee voluntarily updates its Section III Code of record. If a Code 2 Except for Code Cases pertaining to high-temperature gas-cooled reactors; Section III, Division 2, requirementsnot endorsed by the NRC; liquid metal; and submerged spent fuel waste casks. 3 Case is incorporated by reference into 10 CFR 50.55a and later annulled by the ASMEbecause experience has shown that the design analysis or construction method is nolonger adequate, the NRC will amend 10 CFR 50.55a and this guide to remove theapproval of the annulled Code Case. Licensees should not begin to implement suchannulled Code Cases in advance of the rulemaking. Notwithstanding theserequirements, the Commission may impose new or revised Code requirements, including implementation schedules, that it determines are consistent with the backfitrule (i.e., 10 CFR 50.109). With regard to the use of any Code Case, it is the responsibility of the user to make certain that the provisions of the Code Case do not conflict with regulatoryrequirements or licensee commitments. C. REGULATORY POSITION 1. ACCEPTABLE CODE CASES The Code Cases listed in Table 1 below are acceptable to the NRC for application in the design and construction of components and their supports for water-cooled nuclear power plants. The ASME issues Section III Code Cases quarterly insupplements to a specific edition, i.e., a new edition of Section III is published every three years, and supplements are published quarterly. Hence, there are 12 supplementsto each edition. Column 3 of Table 1 lists the supplement and edition in which eachCode Case was published (e.g., 7/95E means Code Case Supplement 7 to the 1995Edition).

CONDITIONALLY ACCEPTABLE SECTION III CODE CASES The Code Cases listed in Table 2 below are acceptable to the NRC for application in the design and construction of components and their supports for water-cooled nuclearpower plants within the limitations indicated by the NRC. Unless otherwise stated,limitations indicated by the NRC are in addition to the conditions specified in the CodeCase. The ASME issues Section III Code Cases quarterly in supplements to a specificedition; i.e., a new edition of Section III is published every three years, and supplementsare published quarterly. Hence, there are 12 supplements to each edition. Column 3 ofthe table lists the supplement and edition in which each Code Case was published (e.g.,7/95E means Code Case Supplement 7 to the 1995 Edition). TABLE 2 - CONDITIONALLY ACCEPTABLE SECTION III CODE CASES CODECASENUMBERN-62-7 TABLE 2, CONDITIONALLY ACCEPTABLE CODE CASES TITLE / CONDITION Internal and External Valve Items, Section III, Division 1,Classes 1, 2, and 3 The Code requires that Class 1 and Class 2 valve manufacturers meet the provisions of NCA-4000, “QualityAssurance.” Class 3 valve manufacturers must also meetthe provisions of NCA-4000 because all Code Class valveitems are subject to the licensee’s 10 CFR 50, Appendix Bapproved QA program. N-71-17 Additional Materials for Subsection NF, Class 1, 2, 3, and MCComponent Supports Fabricated by Welding, Section III,Division 1 (1) The maximum measured ultimate tensile strength (UTS)of the component support material must not exceed 170 Ksiin view of the susceptibility of high-strength materials tobrittleness and stress corrosion cracking. (2) Certain applications may exist where a UTS value of upto 190 Ksi could be considered acceptable for a materialand, under this condition, the Design Specification mustspecify impact testing for the material. For these cases, itmust be demonstrated by the applicant that: (a) the impacttest results for the material meet Code requirements, (b) thematerial is not subject to stress corrosion cracking by virtueof the fact that: (i) a corrosive environment is not presentand (ii) the component that contains the material has essentially no residual stresses or assembly stresses, andit does not experience frequent sustained loads in service. 6/98ESUPPLEMENT/EDITION 8/98E 9 CODECASENUMBERN-71-17(cont’d) TABLE 2, CONDITIONALLY ACCEPTABLE CODE CASES TITLE / CONDITION Additional Materials for Subsection NF, Class 1, 2, 3, and MCComponent Supports Fabricated by Welding, Section III,Division 1 (3) In the last sentence of paragraph 5.3, reference must bemade to paragraph 4.5.2.2, “Alternate Atmosphere Exposure Time Periods Established by Test,” of the AWSD.1.1 Code for the evidence presented to and accepted bythe Authorized Inspector concerning exposure of electrodesfor longer periods of time.

Additional Materials for Component Supports and Alternate DesignRequirements for Bolted Joints, Section III, Division 1, SubsectionNF, Class 1, 2, 3, and MC Construction The maximum measured ultimate tensile strength (UTS) ofthe component support material should not exceed 170 Ksi inview of the susceptibility of high-strength materials tobrittleness and stress corrosion cracking. Certain applications may exist where a UTS value of up to 190 Ksicould be considered acceptable for a material and, under thiscondition, the Design Specification should specify impacttesting for the material. For these cases, it should be demonstrated by the applicant that (1) the impact test resultsfor the material meet code requirements, and (2) the materialis not subject to stress corrosion cracking by virtue of the factthat (a) a corrosive environment is not present and (b) thecomponent that contains the material has essentially noresidual stresses or assembly stresses, and it does notexperience frequent sustained loads in service.
