U.S. NUCLEAR REGULATORY COMMISSION March 2016 OFFICE OF NUCLEAR REGULATORY RESEARCH Division 1 DRAFT REGULATORY GUIDE Technical Contact Anthony Cinson (301) 415-2393 DRAFT REGULATORY GUIDE DG-1295 (Proposed Revision 37 of Regulatory Guide 1.84, dated March 2016)

DESIGN, FABRICATION, AND MATERIALS CODE CASE ACCEPTABILITY, ASME SECTION III Purpose This regulatory guide (RG) lists the American Society of Mechanical Engineers (ASME)

Section III Code Cases that the U.S. Nuclear Regulatory Commission (NRC) has approved for use as voluntary alternatives to the mandatory ASME Boiler and Pressure Vessel (BPV) Code provisions that are incorporated by reference into Title 10, Part 50, of the Code of Federal Regulations (10 CFR Part 50),

Domestic Licensing of Production and Utilization Facilities (Ref. 1).

Applicable Rules and Regulations

General Design Criterion (GDC) 1, Quality Standards and Records, of Appendix A, General Design Criteria for Nuclear Power Plants, to 10 CFR Part 50 requires, in part, that structures, systems, and components important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety function to be performed.

Where generally recognized codes and standards are used, Criterion 1 requires that they be identified and evaluated to determine their applicability, adequacy, and sufficiency and be supplemented or modified 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 to 10 CFR Part 50 requires, in part, that components that are part of the reactor coolant pressure boundary be designed, fabricated, erected, and tested to the highest practical quality standards.

This regulatory guide is being issued in draft form to involve the public in the early stages of the development of a regulatory position in this area. It has not received final staff review or approval and does not represent an official NRC final staff position.

Public comments are being solicited on this draft guide (including any implementation schedule) and its associated regulatory analysis or value/impact statement. Comments should be accompanied by appropriate supporting data. Written comments may be submitted to the Rules, Announcements, and Directives Branch, Office of Administration, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; submitted through the NRCs interactive rulemaking Web page at http://www.nrc.gov; or faxed to (301) 492-3446. Copies of comments received may be examined at the NRCs Public Document Room, 11555 Rockville Pike, Rockville, MD. Comments will be most helpful if received by 5/16/2016.

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 of special processing of materials and that proper testing be performed.

The regulation in 10 CFR 50.55a(c), Reactor Coolant Pressure Boundary, requires, in part, that components of the reactor coolant pressure boundary must be designed, fabricated, erected, and tested in accordance with the requirements for Class 1 components of Section III, Rules for Construction of Nuclear Power Plant Components (Ref. 2), of the ASME BPV Code or equivalent quality standards.

Related Guidance

Regulatory Guide 1.147, Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1 (Ref. 3), lists the ASME Section XI Code Cases that the NRC has approved for use as voluntary alternatives to the mandatory ASME BPV Code provisions that are incorporated into 10 CFR 50.55a.

Regulatory Guide 1.192, Operation and Maintenance Code Case Acceptability, ASME OM Code (Ref. 4), lists the ASME Operation and Maintenance Code (OM Code) Code Cases that the NRC has approved for use as voluntary alternatives to the mandatory ASME OM Code provisions that are incorporated into 10 CFR 50.55a.

Regulatory Guide 1.193, ASME Code Cases Not Approved for Use (Ref. 5), lists the ASME Section III and Section XI Code Cases that the NRC has not approved for generic use.

Purpose of This Regulatory Guide The NRC will amend 10 CFR 50.55a to incorporate by reference the new Code Cases and revisions to existing Code Cases listed as approved in Tables 1 and 2 of this guide, and to state the requirements governing the use of Code Cases. Code Cases approved by the NRC may be used voluntarily by licensees as an alternative to compliance with ASME Code provisions that have been incorporated by reference into 10 CFR 50.55a. Because of continuing change in the status of Code Cases, the staff plans periodic updates to 10 CFR 50.55a and this guide to accommodate new Code Cases and any revisions of existing Code Cases.

Paperwork Reduction Act (Ref. 6)

This regulatory guide contains information collection requirements covered by 10 CFR Part 50 that the Office of Management and Budget (OMB) approved under OMB control number 3150-0011. The NRC may neither conduct nor sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid OMB control number.

B. DISCUSSION Reason of Revision Draft Revision 37 of RG 1.84 includes new information reviewed by the NRC of Section III Code Cases listed in Supplement 11 to the 2007 Edition and Supplements 0 through 10 to the 2010 Edition.

This is an update to RG 1.84, Revision 36, which included information from Supplements 1 through 10 to the 2007 Edition.

Background

Provisions of the ASME BPV Code have been used since 1971 as one part of the framework to establish the necessary design, fabrication, construction, testing, and performance requirements for structures, systems, and components important to safety. Among other things, ASME standards committees develop improved methods for the construction and inservice inspection (ISI) of ASME Class 1, 2, 3, MC (metal containment), and CC (concrete containment) nuclear power plant components. A broad spectrum of stakeholders participates in the ASME process, which helps to ensure that the various interests are considered.

The ASME publishes a new edition of the BPV Code, which includesSection III, every 2 years.

The latest edition of Section III that the NRC has approved for use are referenced in 10 CFR 50.55a(a)(1)(i). The ASME also publishes Code Cases quarterly. Code Cases provide alternatives developed and approved by ASME. This regulatory guide 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 yet endorsed by the NRC may be used by a licensee or applicant through 10 CFR 50.55a(z).

That section permits the use of alternatives to the Code requirements referenced in 10 CFR 50.55a provided that the proposed alternatives result in an acceptable level of quality and safety, and that their use is authorized by the Director of the Office of Nuclear Reactor Regulation, or Office of New Reactors, as applicable.

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 mandatory ASME Code provisions.

Requirements related to Code Case implementation are provided in 10 CFR 50.55a(b). When a licensee initially applies a Code Case listed in Tables 1 or 2 of this guide, the licensee must implement the most recent version of that Code Case incorporated by reference in 10 CFR 50.55a.

Code Cases may be annulled because the provisions have been incorporated into the Code, the application for which it was specifically developed no longer exists, or experience has shown that the design analysis or construction method is no longer required. After the ASME annuls a Code Case and the NRC amends 10 CFR 50.55a and this guide, applicants or licensees may not implement that Code Case for the first time. However, a licensee or an applicant who implemented the Code Case prior to annulment may continue to use that Code Case until the licensee voluntarily updates itsSection III Code of record. If a Code Case is incorporated by reference into 10 CFR 50.55a and later annulled by the ASME because experience has shown that the design analysis or construction method is no longer required, the NRC will amend 10 CFR 50.55a and this guide to remove the approval of the annulled Code Case. Licensees or applicants should not begin to implement such annulled Code Cases in advance of the rulemaking. Notwithstanding these requirements, the Commission may impose new or revised Code DG-1295, Page 3

requirements, including implementation schedules, which it determines are consistent with the Backfit Rule (10 CFR 50.109).

A Code Case may be revised, for example, to incorporate user experience. The older or superseded version of the Code Case cannot be applied by the licensee or applicant for the first time. If an applicant or a licensee applied a Code Case listed in Tables 1 or 2 of this guide before it was listed as superseded, the applicant or the licensee may continue to use the Code Case until the applicant or the licensee updates its construction Code of Record (in the case of an applicant, updates its application). If a Code Case is incorporated by reference into 10 CFR Part 50.55a and later a revised version is issued by the ASME because experience has shown that the design analysis, construction method, examination method, or testing method is inadequate; the NRC will amend 10 CFR Part 50.55a and the relevant RG to remove the approval of the superseded Code Case. Applicants and licensees should not begin to implement such superseded Code Cases in advance of the rulemaking.

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 licensee commitments or regulatory requirements.

C. REGULATORY POSITION For Revision 37 of Regulatory Guide 1.84, the NRC reviewed the Section III Code Cases listed in Supplement 11 to the 2007 Edition and Supplements 0 through 10 to the 2010 Edition of the ASME BPV Code 1. Appendix A to this guide lists the supplements reviewed, the edition, the supplement number, and the date on which the supplement was approved by the ASME Board on Nuclear Codes and Standards.

Appendix B is a list of the Section III Code Cases published by the ASME in the eleven supplements.

Finally, Appendix C is a current list of all Section III Code Cases. The Code Cases addressed by this regulatory guide are listed in five tables:

(1) Table 1, Acceptable Section III Code Cases, contains the Code Cases that are acceptable to the NRC for application in the design and construction of light-water-cooled nuclear power plants.

(2) Table 2, Conditionally Acceptable Section III Code Cases, contains Code Cases that are acceptable provided that they are used with the identified conditions (i.e., the Code Case is generally acceptable but the NRC has determined that requirements in the Code Case, which are alternatives to the BPV Code, must be supplemented in order to provide an acceptable level of quality and safety).

(3) Table 3, Annulled Unconditionally Approved Section III Code Cases, contains the Code Cases that have been annulled by the ASME.

(4) Table 4, Annulled Conditionally Acceptable Section III Code Cases, contains the Code Cases that the NRC determined to be acceptable, provided that they were used with the identified conditions, but were subsequently annulled by the ASME.

(5) Table 5,Section III Code Cases That Have Been Superseded by Revised Code Cases on or After July 1, 1974, lists Code Cases that have been superseded through revision.

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. Code Cases are published quarterly in supplements to each edition. To assist users, new and revised Code Cases are shaded to distinguish them from those approved in previous versions of this guide. The shading will assist in focusing attention during the public comment period on the changes to the guide. For Code Cases previously listed in this guide, the third column of Table 1 lists the date of ASME approval. For new or revised Code Cases, the third column of Table 1 lists the supplement and edition in which each Code Case was published (e.g., 5/10E means Code Case Supplement 5 to the 2010 Edition).

1 Except for Code Cases pertaining to high-temperature gas-cooled reactors; certain requirements in Section III, Division 2, not endorsed by the NRC;Section III, Division 2; and liquid metal.

N-31-1 Elastomer Diaphragm Valves,Section III, Division 1, Classes 2 and 3 7/01/93 Each applicant who applies the Code Case should indicate in the referencing safety analysis report that the service life of the elastomer diaphragm should not exceed the manufacturers recommended service life. This recommended service life should not exceed 1/3 of the minimum cycle life as established by the requirements of paragraph 3 of the Code Case. In addition, the service life of the elastomer diaphragm should not exceed 5 years, and the combined service and storage life of the elastomer diaphragm should not exceed 10 years.

N-32-4 Hydrostatic Testing of Embedded Class 2 and Class 3 Piping 3/16/84 for Section III, Division 1 Construction The acceptance of Code Case N-32-4 was based on the following clarification and interpretation. Code Case N-32-4 does not replace paragraph NC/ND-6129, Provisions for Embedded or Inaccessible Welded Joints in Piping, of the Code. The intent of the Code Case is to (1) provide additional testing above Code requirements and (2) permit liquid penetrant or magnetic particle testing in place of radiographic testing for Class 3 piping with 3/8" nominal wall thickness or less.

Paragraph (1) contains an additional requirement to the Code. It was, therefore, acceptable but unnecessary to include in the Code Case.

Paragraph (2) is a variation in the volumetric examination technique and was acceptable as written. Paragraph (3) contains an additional requirement and is not a relaxation of the Code. It was, therefore, acceptable but unnecessary to include in the Code Case.

N-92 Waiver of Ultrasonic Transfer Method,Section III, V, and VIII, 7/13/81 (1698) Division 1 The material from which the basic calibration block is fabricated should be of the same product form, alloy, and heat treatment as the material being examined. Alloys of equivalent P-number grouping may be used for the fabrication of calibration blocks if adjustments to signal height can be made to compensate for sound beam attenuation difference between the calibration block and the material under examination by following the transfer method procedure of T-535.1(d), Article 5,Section V, ASME BPV Code, 1977 Edition.

Code Case Table 4 Annulment Number Annulled Conditionally Acceptable Section III Code Cases Date Title/Condition N-100 Pressure Relief Valve Design Rules,Section III, Division 1, Class 1, 2 and 3 1/01/83 (1711) The following information should be provided in the safety analysis report:

(1) If stress limits are used in excess of those specified for the upset operating condition, it should be demonstrated how the pressure relief function is ensured. Refer to paragraph 3.1,Section I, of the Code Case for Class and paragraph 3.2,Section II, of the Code Case for Class 2 and 3 pressure relief valves.

(2) If Code Case 1660 is to be used in conjunction with the Code Case, it should be stated that the stress limits of Code Case 1660 supersede those of paragraph 3.2(b),Section I, of Code Case 1711. Functional assurance of (1) above is required in all situations.

N-106-2 Weld End Preparation for Section III, Division 1 Construction 8/14/93 (1720-2) The acceptance of weld end preparations other than those shown in Figures 1, 2, and 3 of the Code Case should be evaluated on a case-by-case basis.

N-110 Alternate Test Fluids,Section III, Division 1 1/01/79 (1727) The applicant should provide justification in the referencing safety analysis report for the fluid selected for use in the pressure test. The information provided should demonstrate that the fluid selected will not have deleterious effects on the material of the pressure boundary and that the fluid may be safely used at the specified temperature and pressure of the test. When the fluid selected for use is the operating fluid, additional information is not required.

N-116 Weld Design for Use for Section III, Division 1, Class 1, 2, 3 and MC 1/01/78 (1734) Construction of Component Supports If the configuration of Figure 1 of the Code Case is used for Class 1 and MC components supports, full penetration welds should be used. The application of the configuration shown in Figures 2 and 3 should be restricted to the welding of cans for spring encapsulation in spring hangers. In Figure 3, the length of the leg of the fillet weld adjacent to the plate should be equal to the thickness of the exposed edge of the plate; also, the leg of the fillet weld adjacent to the shell should be equal to the thickness of the exposed end of the shell.

N-146-1 Hydrostatic Testing and Stamping of Components,Section III, 1/01/82 (1780-1) Division 1, Construction On a generic basis, the application of the Code Case is limited to pumps and valves. Application to other components should be treated on a case-by-case basis. Each licensing application in which the Code Case is to be used should contain information showing that, as a minimum the closure fixture will impose loads that result in stresses equal to or greater than those induced during the hydrostatic test of a complete pump assembly. A closure fixture for the part being tested that is similar in size and shape to the actual mating part is considered adequate to impose these loads. It is not intended that piping reaction loadings be simulated in the hydrostatic testing.

N-411 Alternative Damping Values for Seismic Analysis of Classes 1, 2, and 3 Piping Sections, 2/20/86 Section III, Division 1 (1) The damping values specified may be used in analyzing piping response for seismic and other dynamic loads being filtered through building structures provided response mode frequencies are limited to 33 Hz and below. Within this range, the Code Case damping should be used completely and consistently, if used at all. [For equipment other than piping, the damping values specified in Regulatory Guide 1.61 (Ref. 10), should be used.]

(2) The damping values specified may be used only in those analyses in which current seismic spectra and procedures have been employed. Such use should be limited only to response spectral analyses [similar to that used in the study supporting its acceptance, NUREG/CR-3526 (Ref. 11)]. The acceptance of the use with other types of dynamic analyses (e.g., time-history analysis) is pending further justification.

(3) When used for reconciliation work or for support optimization of existing designs, the effects of increased motion on existing clearances and on line mounted equipment should be checked.

(4) This Code Case is not appropriate for analyzing the dynamic response of piping systems using supports designed to dissipate energy by yielding (i.e., the design of which is covered by Code Case N-420).

(5) This Code Case is not applicable to piping in which stress corrosion cracking has occurred unless a case-specific evaluation is made and is reviewed by the NRC staff.
