GUIDE 1.28 QUALITY ASSURANCE
PROGRAM REQUIREMENTS (DESIGN AND CONSTRUCTION) (Task RS 002-5)
A. INTRODUCTION
Nuclear power plants and fuel reprocessing plants include structures, systems, and components that prevent or mitigate the consequences of postulated accidents that could cause undue risk to the health and safety of the public. Appendix B to 10 CFR Part 50 establishes quality assurance requirements for the design, construc tion, and operation of those structures, systems, and components.
The pertinent requirements of Appendix B apply to all activities affecting the safety-related func tions of those structures, systems, and components.
These activities include designing, purchasing, fabricating, handling, shipping, storing, cleaning, erecting, installing, inspecting, testing, operating, maintaining, repairing, refueling, and modifying.
This regulatory guide describes a method acceptable to the NRC staff for complying with the provisions of Appendix B with regard to establishing and implement S, ing the requisite quality assurance program for the design and construction of nuclear power plants. Guid ance for the establishment and execution of quality assurance programs during operation and decommission ing of nuclear power plants have been or will be addressed in separate regulatory guides. Similarly, quality assurance provisions concerning fuel cycle facilities have been or will be addressed in separate regulatory guides. Any information collection activities mentioned in this regulatory guide that may be subject to the Paperwork Reduction Act of 1980 (44 U S.C. 3501 et seq.) have been reviewed by the Office of Management and Budget and were included in OMB Approval No. 3150-0011.
The Advisory Committee on Reactor Safeguards has been consulted concerning this guide and has concurred in the regulatory position.
- The substantial number of changes in this revision has made it impractical to indicate the changes with lines in the margins.
B. DISCUSSION
Regulatory Guide 1.28 (Safety Guide 28) was issued in June 1972 and endorsed the general requirements and guidelines for establishing and executing a quality assurance program during the design and construction phases of nuclear power plants provided in ANSI N45.2 1971,1 "Quality Assurance Program Requirements for Nuclear Power Plants." This standard had been devel oped by Subcommittee N45-2.7 (formerly N45-3.7) of the American National Standards Committee N45, Reac tor Plants and Their Maintenance, and provided general requirements for establishing and executing a quality assurance program during the design, construction, and operation of nuclear power plants. ANSI N45.2-1971 was later revised to update its requirements and to expand its applicability to other nuclear facilities that were subject to Appendix B to 10 CFR Part 50. That revised standard was subsequently approved and designated ANSI/ASME
N45.2-1977,' "Quality Assur ance Program Requirements for Nuclear Facilities," by the American National Standards Institute (ANSI) on April 7, 1977. Revision 1 to Regulatory Guide 1.28 was issued for public comment in March 1978. With supple mental provisions, it proposed endorsement of the quality assurance program requirements in ANSI/ASME
N45.2-1977 for the design and construction phases of nuclear power plants. In February 1979, the NRC issued Revision 2 to Regulatory Guide 1.28, which, with supplemental provisions, also endorsed the quality assurance program requirements of ANSI/ASME
N45.2 1977 for the design and construction phases of nuclear power plants. The American Society of Mechanical Engineers (ASME) Committee on Nuclear Quality Assurance has prepared a new standard that includes requirements and guidance for establishing and executing quality assurance lCopies may be obtained from the American Society of Mechani cal Engineers, 345 East 47th Street, New York, New York 1001
7. USNRC REGULATORY
GUIDES Regulatory Guides are issued to describe and make available to the public methods acceptable to the NRC staff of implementing specific parts of the Commission's regulations, to delineate tech niques used by the staff In evaluating specific problems or postu lated accidents, or to provide guidance to applicants.
Regulatory Guides are not substitutes for regulations, and compliance with them is not required.
Methods and solutions different from those set S-out 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 Informa tion or experience.
Comments should be sent to the Secretary of the Commission, U.S. Nuclear Regulatory Commission, Washington, DC 20555, Attention:
Docketing and Service Branch. The guides are issued In the following ten broad divisions:
1. Power Reactors 6. Products 2. Research and Test Reactors
7. Transportation
3. Fuels and Materials Facilities
8. Occupational Health 4. Environmental and Siting 9. Antitrust and Financial Review 5. Materials and Plant Protection
10. General Copies of issued guides may be purchased at the current Government Printing Office price. A subscription service for future guides in spe cific divisions is available through the Government Printing Office. Information on the subscription service and current GPO prices may be obtained by writing the Superintendent of Documents, U.S. Government Printing Office, Post Office Box 37082, Washington, DC 20013-7082.
programs for the design, construction, operation, and decommissioning of nuclear facilities.
This standard is based on the contents of ANSI N46.2-1978, ANSI/ ASME N45.2-1977, and the following standards in the ANSI N45.2 series: 1 N45.2.6 "Qualification of Inspection, Examina tion, and Testing Personnel for Nuclear Power Plants" N45.2.9 "Requirements for Collection, Storage and Maintenance of Quality Assurance Records for Nuclear Power Plants" N45.2.10 "Quality Assurance Terms and Defini tions" N45.2.11 "Quality Assurance Requirements for the Design of Nuclear Power Plants" N45.2.12 "Requirements for Auditing of Quality Assurance Programs for Nuclear Power Plants" N45.2.13 "Quality Assurance Requirements for Control of Procurement of Items and Services for Nuclear Power Plants" N45.2.23 "Qualification of Quality Assurance Program Audit Personnel for Nuclear Power Plants" The standard that evolved was approved and desig nated ANSI/ASME
NQA-l-1979,1 "Quality Assurance Program Requirements for Nuclear Power Plants," by ANSI on July 24, 1979. Three addenda to ANSI/ASME
NQA-l-1979 were developed by the American Society of Mechanical Engineers.
These addenda, contained in ANSI/ASME
NQA-la-1981, NQA-lb-1981, and NQA-Ic 1982, were issued by ANSI on April 30, 1981, January 31, 1982, and December 31, 1982, respectively, follow ing approval by the Main Committee of the ASME Committee on Nuclear Quality Assurance.
On July 1, 1983, ANSI/ASME
NQA-1-1983 was issued. It incorpor ated ANSI/ASME
NQA-l-1979 and the NQA-la-1981, NQA-lb-1981, and NQA-Ic-1982 Addenda into the 1983 edition without changing any of the previous requirements, supplements, or appendices described in ANSI/ASME
NQA-1-1979 and addenda. On December 31, 1983, after approval by the Main Committee of the ASME Committee on Nuclear Quality Assurance, the ANSI/ASME
NQA-la-1983 Addenda were issued. They clarified previous sections of ANSI/ASME
The standard notes that addenda will be published up to the publication date of the next edition of the standard.
The NRC staff will evaluate addenda and subsequent editions of NQA-1 after their issuance to determine whether a revision to this guide would be appropriate.
ANSI/ASME
NQA-1-1983 has been organized into three main sections:
(1) Basic Requirements, (2) Supple-ments, and (3) Appendices.
The Basic Requirements section sets forth basic requirements for establishing and executing quality assurance programs.
The Supplements section amplifies the individual requirements of the Basic Requirements section. The Appendices section provides nonmandatory guidance for meeting the Basic Requirements and Supplements sections.
The intent of ANSI/ASME
NQA-l-1983 was to consolidate the quality assurance programmatic standards to reduce redundancy without changing the overall intent of the standard.
This Revision 3 to Regulatory Guide 1.28 was developed to endorse ANSI/ASME
NQA-l-1983.
In its development, the NRC staff intended it to be equivalent to the methods described in Regula tory Guides 1.28 (Rev. 2), 1.58 (Rev. 1), 1.64 (Rev. 2), 1.74, 1.88 (Rev. 2), 1.123 (Rev. 1), 1.144 (Rev. 1), and 1.146. To accomplish this equivalency, parts of the "nonmandatory guidance" in ANSI/ASME
NQA-1-1983 that were previously requirements in the ANSI/ASME
N45.2 series were included as regulatory positions in Proposed Revision 3 to Regulatory Guide 1.28, which was issued in March 1981 for public comment. Also, several of the previous regulatory positions endorsing the ANSI/ASME
N45.2-series standards were included as regulatory positions in Proposed Revision 3 to Regula tory Guide 1.28. Based on public comments and further NRC staff review, the regulatory positions have been reassessed to determine their value and impact on nuclear power plant safety. In this reassessment, the advantage of minimizing the number of exceptions taken to a national standard was considered.
Consequently, a number of regulatory positions that were intended as clarifications to provi sions of the standard were reconsidered and deleted from the regulatory position.
The guide now retains positions in only those areas in which the staff believes additional guidance is necessary.
Retaining these positions also attempts to avoid building in more differences among facilities than already exist. The safety advantage of these positions will be to encourage greater stan dardization of quality assurance practices.
Although the standard contains general provisions covering the subjects addressed in the regulatory positions, it does not pro vide detailed guidance for implementing its general requirements.
Without these positions, detailed case-by case reviews will be necessary in the licensing review process, and the likelihood of unnecessary differences between facilities is increased.
Although ANSI/ASME
NQA-1-1983 provides require ments and guidance for the establishment and execution of quality assurance programs during the design, con struction, operation, and decommissioning of nuclear facilities, this Revision 3 to Regulatory Guide 1.28, with supplemental provisions, addresses only those portions of ANSI/ASME
NQA-l-1983 applicable to the design and construction phases of nuclear power plants. Updated guidance for complying with the Commission's regula tions with regard to quality assurance program require ments for the operations phase of nuclear power plants 1.28-2 will be provided in Regulatory Guide 1.33, Revision 3, "Quality Assurance Program Requirements (Operation)," which is presently undergoing NRC staff review and is .expected to endorse, with supplemental provisions, ANSI/ ANS-3.2-1982, 2 "Administrative Controls and Quality Assurance for the Operational Phase of Nuclear Power Plants." Regulatory Guide 1.8, "Personnel Selection and Training," provides guidance on personnel selection and training, including the qualifications of certain operators, technicians, and maintenance personnel who may perform inspections and tests during preoperational, startup, and operational testing. The requirements of Supplement
2S-1 and recommendations of Appendix 2A-1 in NQA-l also provide guidance on personnel qualifications.
Personnel performing inspection and testing that are' qualified to the guidance contained in Regulatory Guide 1.83 need not be qualified in accordance with the requirements of NQA-1. It is not the intent that such personnel be qualified in accordance with both Regu latory Guide 1.8 and NQA-1. In the development of Regulatory Position 2, "Quality Assurance Records," Section 3 of Appendix 17A-1 was used in the preparation of Table 1 in accordance with the requirements for records classification defined in paragraph
2.7 of Supplement
17S-I. Although Table 1 provides a list of nonpermanent and lifetime records and their respective retention times, the emphasis should be placed on the quality of the product rather than the records generated.
If an applicant or licensee indicates to the NRC that it will conform to 'the recommendations of this regulatory guide and it does not qualify its willingness to conform, it has agreed to comply with the require ments of ANSI/ASME
NQA-l-1983 and the ANSI/ASME
NQA-la-1983 Addenda, as supplemented or modified by the regulatory positions in this guide. An applicant or licensee that has committed itself to the recommendations of this regulatory guide is respon sible for ensuring that the requirements of ANSI/ASME
NQA-l-1983 and the ANSI/ASME
NQA-la-1983 Addenda, as supplemented or modified by the regulatory positions of this guide, are met by its suppliers to the extent necessary.

' 3In response to Section 306 of Public Law 97-425, the lessons learned from the Three Mile Island accident, public comments, and additional staff review, a third Proposed Revision 2 to Regu latory Guide 1.8 entitled "Qualification and Training of Personnel for Nuclear Power Plants" was issued for public comment in January 1985 with the identification number Task OL 403-5.execution of quality assurance programs during the design and construction phases of nuclear power plants are acceptable to the NRC staff and provide an adequate basis for complying with the pertinent quality assurance requirements of Appendix B to 10 CFR Part 50, subject to the additions and modifications to ANSI/ASME
NQA-l-1983 and the ANSI/ASME
NQA-la-1983 Addenda identified below.
1. QUALIFICATION
OF INSPECTION
AND TEST PERSONNEL
Appendix 2A-1, "Nonmandatory Guidance on the Qualifications of Inspection and Test Personnel," pro vides guidance on the qualifications of inspection and test personnel The provisions of Appendix 2A-1 (or acceptable alternatives)
should be met as part of Supple ment 2S-1, "Supplementary Requirements for the Quali fication of Inspection and Test PersonneL"
2. QUALITY ASSURANCE
RECORDS Section 2.8, "Retention of Records," of Supplement
17S-1, "Supplementary Requirements for Quality Assur ance Records," states that the retention period for nonpermanent records is required to be established in writing. Programmatic nonpermanent records 4 should be retained for at least 3 years and product nonperma nent records 5 should be retained for at least 10 years or -the life of the item if less than 10 years. For programmatic nonpermanent records, the retention period should. be considered to begin upon completion of the activity.
For product nonpermanent records generated before commercial operation begins, the retention period should be considered to begin upon completion of delivery.
In addition, product and programmatic nonpermanent records should be retained at least until the date of issuance of the full-power operating license of the unit. Table 1 provides a list of nonpermanent and lifetime records and their respective retention times, Although Table 1 is intended to be a comprehensive list, it is the responsibility of the owner to assure itself, in accordance with Criterion
17 of Appendix B to 10 CFR Part 50, that sufficient records are maintained to furnish evidence of activities affecting quality. It should be recognized that the nomenclature of these records may vary. For records not listed in Table 1, the type most nearly describing the record in question should be followed with respect to its reten tion period. 4 Programmatic nonpermanent records are those documents that were used to prescribe activities affecting quality but that are not considered permanent records. Such records include docu ments prescribing the planning, execution, and auditing of activities affecting quality. Records such as audit checklists, audit results, and actual examinations used to qualify inspection and test personnel are included in this category.
5 ,Product nonpermanent records document that specific struc tures, systems, and components of a nuclear power plant have been designed and constructed in accordance with applicable require ments but are such that it is not necessary to retain them as lifetime records. These records include design verification data, receiving records, calibration records, maintenance records, inspection records, radiographs not associated with inservice inspection, and test records that are not otherwise designated as lifetime records.1.28-3
3. AUDITS Section 2, "Scheduling," of Supplement
18S-1, "Supplementary Requirements for Audits," requires audits to be scheduled in a manner that provides coverage and coordination with ongoing quality assur ance program activities.
The following guidelines are considered acceptable for scheduling audits: 3.1 Internal Audits Applicable elements of an organization's quality assurance program should be audited at least once each year or at least once during the life of the activity, whichever is shorter. In determining the scope of the audit, an evaluation of the activity being audited may be useful. The evaluation may include results of previous quality assurance program audits and the results of audits from other sources, including the nature and frequency of identified deficiencies and any significant changes in personnel, organization, or quality assurance program.
3.2 External Audits After the award of a contract, the applicant or licensee may determine, based on the evaluation con ducted in accordance with Section 5.1 of Appendix 4A-1, that external audits are not necessary for procur ing items that are (1) relatively simple and standard in design, manufacturing, and testing and (2) adaptable to standard or automated inspections or tests of the end product to verify quality characteristics after delivery.
For other procurement actions not covered by the above exceptions, audits should be conducted as described below. 1. The applicant or licensee should either audit its supplier's quality assurance program on a triennial basis or arrange for such audit. In either case, the audit should be implemented in accordance with Supplement
18S-1 of ANSI/ASME
NQA-l-1983.
The triennial period begins when an audit is performed.
An audit may be performed when the supplier has completed sufficient work to demonstrate that its organization is implement ing a quality assurance program that has the required scope for purchases placed during the triennial period. If a subsequent contract or a contract modification signif icantly enlarges the scope of or changes the methods or controls for activities performed by the same supplier, an audit of the modified requirements should be con ducted, thus starting a new triennial period. If the supplier is implementing the same quality assurance program for other customers that is proposed for use on the auditing party's contract, the pre-award survey may serve as the first triennial audit if conducted in accor dance with the requirements of ANSI/ASME
NQA-l 1983. Therefore, when such pre-award surveys are employed as the first triennial audits, they should satisfy the same audit elements and criteria as those used on other triennial audits.2. The applicant or licensee should perform or arrange for annual evaluations of suppliers.
This evalua tion should be documented and should take into account, where applicable, (1) review of supplier.
furnished documents and records such as certificates of conformance, nonconformance notices, and corrective actions; (2) results of previous source verifications, audits, and receiving inspections;
(3) operating experience of identical or similar products furnished by the same supplier;
and (4) results of audits from other sources, e.g., customer, ASME, or NRC audits. 3. If more than one purchaser buys from a single supplier, a purchaser may either perform or arrange for an audit of the supplier on behalf of itself and other purchasers to reduce the number of external audits of the supplier.
The scope of this audit should satisfy the needs of all of the purchasers, and the audit report should be distributed to all the purchasers for whom the audit was conducted.
Nevertheless, each of the purchasers relying on the results of an audit performed on behalf of several purchasers remains individually responsible for the adequacy of the audit.
D. IMPLEMENTATION
The methods described in this revision (through endorsement of ANSI/ASME
NQA-1-1983 and the ANSI/ASME
NQA-la-1983 Addenda) for complying with the provisions -of Appendix B to 10 CFR Part 50 with regard to the establishment and implementation of the requisite quality assurance program are considered to be generally equivalent, from a programmatic standpoint, to the methods described in Revision 2 to Regulatory Guide 1.28 and Regulatory Guides 1.58, 1.64, 1.74, 1.88, 1.123, 1.144, and 1.146 (through endorsement of ANSI/ASME
N45.2 and seven programmatic ANSI/ ASME N45.2-series standards).
Applicants and licensees that have committed to ANSI/ASME
N45.2 and the appropriate ANSI N45.2 series standards as addressed in the applicable regula tory guides may continue to follow ANSI/ASME
N45.2 and the appropriate ANSI/ASME
N45.2-series standards instead of ANSI/ASME
NQA-l-1983.
Applicants and licensees may commit to follow either the ANSI/ASME
N45.2-series standards or the ANSI/ASME
NQA-l-1983 standard but not a combination of the two. Because ANSI/ASME
NQA-1-1983 consolidates ANSI/ ASME N45.2 and the seven programmatic ANSI/ASME
N45.2-series standards, these standards have been replaced with ANSI/ASME
NQA-l-1983.
Consequently, except in those cases in which an applicant or licensee proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described in this revision will be used in the evaluation of all new (1) construction permit applications, (2) standard design approvals that can be referenced in construction permit applications, and (3) licenses to manufacture.

ANALYSIS
1. STATEMENT
OF THE PROBLEM Appendix B to 10 CFR Part 50, "Quality Assurance Criteria for Nuclear Power Plants and Fuel Reproces sing Plants," sets forth the quality assurance require ments for the design, construction, and operation of those structures, systems, and components that prevent or mitigate the consequences of postulated accidents that could cause undue risk to the health and safety of the public. Current guidance on controls the NRC staff con siders acceptable for complying with Appendix B to 10 CFR Part 50 concerning programmatic quality assurance requirements during design and construction is provided in a number of regulatory guides that endorse the standard ANSI/ASME
N45.2-1977, "Quality Assurance Program Requirements for Nuclear Facilities," and seven N45.2-series standards that cover specific quality assurance topics. A new standard, ANSI/ASME
NQA-l-1979, approved by the American National Standards Institute on July 24, 1979, con consolidates ANSI/ASME
N45.2-1977 and these seven N45.2-series standards.
The intent of ANSI/ASME
NQA-1-1979 was to consolidate the programmatic standards to avoid redundancy without changing their intent. ANSI/ASME
NQA-l-1979 is a second genera tion standard in which industry experience is reflected in changing certain controls and also eliminating certain activities considered to be ineffective in enhancing quality or the overall effectiveness of the program.
ANSI/ASME
NQA-1-1979 was developed through I a consensus agreed to by the American National Stan dards Institute.
On July 1, 1983, NQA-1-1979 and the NQA-la-1981, NQA-lb-1981, and NQA-Ic-1982 Addenda were incorporated into NQA-l-1983 without changing any of the requirements, supplements, or appendices deicribed in ANSI/ASME
As encouraged by the Office of Management and Budget (OMB) Circular No. A-I19, "Federal Participa tion in the Development and Use of Voluntary Stan dards," which was published as a final rule in the Federal Register November 1, 1982 (47 FR 49496), several NRC representatives participated in the develop ment of ANSI/ASME
NQA-l-1983.
Since ANSI/ASME
NQA-1-1983 represents a consolidation of the seven programmatic N45.2-series standards, these standards along with ANSI/ASME
N45.2-1977 will not be revised to incorporate any new positions and will eventually be replaced with ANSI/ASME
NQA-l-1983 and the ANSI/ASME
NQA-la-1983 Addenda. This standard is now published in its final form and the NRC must decide what action to take concerning endorsement of the standard.
The consequences of the NRC staff taking no action in the development or endorsement of the standard would result in the NRC staff having to either ignore the NQA-1 effort and continue to rely on Revision 2 of Regulatory Guide 1.28 (which in essence means living with ANSI/ASME
N45.2-1977 and the seven daughter standards)
or develop its own guidance or standard to achieve a consolidated docu ment and minimize redundancy.
2. OBJECTIVES
Proposed Revision 3 to Regulatory Guide 1.28 endorsing ANSI/ASME
NQA-1-1983 focuses on the following three objectives:
I. Endorse the consolidation of ANSI/ASME;
N45.2 and the seven ANSI/ASME
N45.2-series standards into one document,'
thus eliminating certain redundancies and certain activities.
2. Consolidate the eight applicable NRC regulatory guides endorsing the above ANSI/ASME
standards into one document.
3' Reflect current NRC guidance, from a program matic standpoint, concerning quality assurance during design and construction of nuclear power plants and fuel reprocessing facilities.
In developing Revision 3 to Regulatory Guide 1.28 (through endorsement of ANSI/ASME
NQA-1-1983), it was the intent that Revision 3 would be equivalent to the methods described by Revision 2 to Regulatory Guide 1.28 and Regulatory Guides 1.58, 1.64, 1.74, 1.88, 1.123, 1.144, and 1.146 (through endorsement of ANSI/ASME
N45.2 and the programmatic N45.2-series standards).
In order to achieve this equivalence, parts of the "nonmandatory guidance" of ANSI/ASME
NQA-1-1983 that were previously requirements in the ANSI/ASME
N45.2-series standards will be treated the same as requirements of ANSI/ASME
NQA-l-1983, ie., a commitment to follow Regulatory Guide 1.28, Revision 3, without exceptions will be a commitment to follow the requirements of ANSI/ASME
NQA-1 1983 and the endorsed "nonmandatory guidance" of the standard.
In addition, some of the regulatory positions related to the ANSI/ASME
N45.2-series standards were retained in order to achieve equivalence and provide consistency in the quality assurance program review process. The guide does indicate that it describes a method acceptable to the NRC staff for complying with the provisions of Appendix B to 10CFR Part 50 with regard to the establishment and implementation of a quality assurance program during design and construction of nuclear power plants. This does represent a change from the guide issued for public comment since the present Regulatory Guide 1.28 (Revision
2) references only Appendix B to 10 CFR Part 50, and the references to Appendix A to 10 CFR Part 50 have been deleted from the proposed Revision 3 to Regulatory Guide 1.28. The NRC staff 1.28-10
is currently examining on a generic basis the subject ol how to implement the quality assurance provisions ol Appendix A to 10 CFR Part 50 for structures, sys. tems, and components important to safety. The subjecl of application of a quality assurance program for itemi important to safety but not safety related is beinj addressed separately by the NRC staff in connection S-with the January 5, 1984, generic letter to all holders of operating licenses, applicants for operating licenses, and holders of construction permits for power reactors concerning the use of the terms "Important to Safety" and "Safety Related."
3. ALTERNATIVES
The following alternatives were considered with respect to revising Regulatory Guide 1.28: 3.1 Alternative
1 Remain with the NRC regulatory guides presently endorsing ANSI/ASME
N45.2 and the seven program matic daughter standards.
Any new or revised quality assurance regulatory positions considered sufficiently important to ensure protection of the public health and safety could be incorporated through appropriate revisions to the applicable quality assurance regulatory guides. 3.2 Alternative
2 Develop a consolidated version of quality assurance guidance for design and construction in the form of a regulatory guide or NUREG-series document. 3.3 Alternative
3 Review 1.28 to equivalent previously
1.28.NQA-1-1983 and revise Regulatory Guide ensure quality assurance program controls (from a programmatic standpoint)
to those endorsed by Revision 2 to Regulatory Guide 4. CONSEQUENCES, COSTS, AND BENEFITS OF EACH ALTERNATIVE
4.1 Alternative
1 Benefits:
Alternative
1 eliminates the need to devote NRC resources to the review and evaluation of ANSI/ ASME NQA-1-1983 in order to formulate NRC positions commensurate with current quality assurance require ments. Licensees, permit holders, vendors, subvendors, and NRC Headquarters and Regional inspection personnel are presently familiar with the quality assurance regula tory guides that endorse the N45.2-series quality assur ance standards.
Also, industry presently has the N45.2-series standards and NRC regulatory guides that endorse these standards in their possession.
Industry and NRC would not be required to spend considerable time, effort, or resources to interpret and implement the r regulatory positions endorsing the Basic Requirements, r Supplements, and selected "nonmandatory guidance" of ANSI/ASME
Also, industry already has these guides and standards at their sites and shops, and their quality assurance manuals and implementing Sprocedures have either incorporated or referenced them I in their documents.
Consequently, little or no effort I would be required of the industry to update should NRC include new positions to existing regulatory guides. Consequences:
ASME has initiated action for ANSI to withdraw the N45.2-series standards that have been consolidated into NQA-I; thus the N45.2-series stan dards will be replaced with NQA-l. Also, as stated in OMB Circular No. A-I 19, policy and administrative guidance is provided to Federal agencies on using voluntary standards for procurement and regulatory purposes and participating with private sector organiza tions to develop such standards as NQA-1. Finally, the 1982 Winter Addenda of the ASME Boiler and Pres sure Vessel Code has endorsed ANSI/ASME
NQA-I 1979 in Sections III and XI and it is expected they will ultimately endorse ANSI/ASME
Costs: The format and subject matter of existing standards and regulatory guides are readily under standable and usable by the 79 licensees, 63 permit holders, and their approximately
700 vendors. Because the majority of the industry has committed to the existing N45.2-series standards and regulatory guides, it would not result in any increased burden or costs to the industry to continue using these documents.
4.2 Alternative
2 Benefits:
From a regulatory viewpoint, this effort would represent precise methods for guidance on how the Commission's quality assurance provisions relating to the design and construction of nuclear power plants must be implemented.
Consequences:
This alternative is contrary to the policy expressed in OMB Circular No. A-119 and has the possibility of bureaucratic delays. Costs: The development of an initial draft of a consolidated quality assurance standard such as ANSI/ ASME NQA-l-1983 would take the NRC staff about two months. The resolution of both internal NRC staff and public comments would take about one year for a total cost of approximately
$120,000 (2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> x $60/hour).
4.3 Alternative
3 Benefits:
Since current guidance for quality assur ance programs is contained in a series of different standards and corresponding regulatory guides, the proposed action will be of value to the NRC staff owing to the consolidation of a large number of requirements and recommendations concerning quality 1.28-11 assurance into a single document consisting of sections on basic requirements, supplemental requirements, and nonmandatory guidance.
The previous eight quality assurance standards and quality assurance regulatory guides that endorsed these standards consisted of approximately
85 pages and the consolidated documents and proposed regulatory guide would consist of approximately
5 pages for "a net reduction of about 80 pages. The previous eight regula tory guides endorsing the standards consolidated into ANSI/ASME
NQA-l-1983 consisted of 46 regulatory positions.
The proposed regulatory guide consists of 3 positions for a net reduction of 43 regulatory positions.
The proposed action also provides an opportunity to incorporate experience from the use of N45.2 and its daughter standards.
Additionally, consolidation of design- and construction-phase quality assurance guid ance should provide a more effective evaluation of compatibility between ANSI quality assurance require ments and the quality assurance requirements in the ASME Boiler and Pressure Vessel Code. ANSI/ASME
NQA-l-1983 represents a consensus document on requirements for quality assurance programmatic action. In a letter dated March 10, 1980, from Jack E. Vessely, Chairman, ASME Main Committee on Nuclear Quality Assurance to W. J. Dircks, Executive Director for Operations of the NRC, early endorsement by the NRC of ANSI/ASME
NQA-1-1979 was requested since, according to the letter, many companies are anxious to use the standard.
However, some members of the industry have indicated reservations regarding the usefulness of this document.
The proposed action establishes an NRC position on an existing national standard and therefore reduces uncertainty as to what the staff considers acceptable in the area of quality assurance requirements for the design and construction of nuclear power plants. The cumulative benefit of the consolidation effort will be to eliminate redundant controls and to incorporate current NRC quality assurance guidance and practices for design and construction of nuclear power plants. The controls described in the regulatory position of Revision 3 to Regulatory Guide 1.28 and the endorse ment of ANSI/ASME
NQA-l-1983 are considered to be generally equivalent, from.a programmatic standpoint, to the controls described in Revision 2 to Regulatory Guide 1.28 and Regulatory Guides 1.58, 1.64, 1.74, 1.88, 1.123, 1.144, and 1.146, which endorse N45.2 and its daughter standards.
As a result, applicants or licensees may commit either to this regulatory guide or to Revision 2 of Regulatory Guide 1.28 and the current issues of the regulatory guides that endorse the seven daugher standards.
However, since ANSI/ASME
NQA-l-1983 consolidates ANSI/ASME
N45.2 and the seven programmatic ANSI/ ASME N45.2-series standards, these standards will be replaced with ANSI/ASME
NQA-l-1983.
Consequently, except in those cases in which an applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described in Revision 3 to Regulatory Guide 1.28 will be used in the evaluation of all new (1) construction permit appli- '-ý cations, (2) standard design approvals that can be refer enced in construction permit applications, and (3) licenses to manufacture.
Consequences:
Should members of the industry (utilities, architect/engineers, nuclear steam supply system suppliers, or vendors) wish to commit to this regula tory guide, indoctrination and training programs would have to be developed to ensure that the regulatory position of Revision 3 to Regulatory Guide 1.28 and the controls of NQA-l-1983 and how these controls are to be implemented are understood.
Particular atten tion would have to be focused on clarifying the poten tial confusion in interpreting the degree to which the Basic Requirements and Supplements Sections, which are addressed as mandatory, and the nonmandatory guidance in ANSI/ASME
NQA-l-1983 are to be implemented.
Also, present principal contractors and utilities that wish to commit to this guide will have to (1) conduct a detailed comparison of existing quality assurance controls and determine what changes are necessary to comply with the new regulatory guide and NQA-1, which, as a minimum, will involve changes from the regulatory guides that endorse N45.2 and its seven daughter standards to Revision 3 to Regulatory Guide 1.28 and ANSI/ASME
NQA-l-1983;
(2) make the neces sary changes to their quality assurance manuals and detailed implementing procedures;
(3) indoctrinate and train the work force on the correct interpretation of the changes and how they are to be implemented;
(4) review their quality assurance programs with the NRC staff to ensure that they are meeting the spirit and intent of the regulatory guide and NQA-1; (5) where necessary, inform contractors, subcontractors, vendors, and subvendors of the changes, including any appropriate indoctrination and training;
and (6) determine the impact on these suppliers relative to additional purchase costs. This may necessitate the utility having to maintain two sets of quality assur ance manuals and two sets of implementing procedures (one set meeting the existing regulatory guides and stan dards and the other set meeting ANSI/ASME
NQA-1 1983). This problem will be compounded because record keeping, audits, and NRC inspections will have to keep in mind which system is being used. Architect/engineers or nuclear steam supply system suppliers working with present contracts to existing regulatory guides and stan dards and ANSI/ASME
NQA-l-1983 would have record keeping and implementation problems similar to the above. Costs: For new applicants, committing to Revision 3 to Regulatory Guide 1.28 may result in lower costs 1.28-12 than committing to the regulatory guides presently endorsing N45.2 and the seven programmatic daughter standards.
The reason is that some of the quality assurance requirements once considered important have now been made nonmandatory guidance in ANSI/ ASME NQA-l-1983.
Also, the fact that certain require ments have been reduced or more clearly defined will also result in lower costs to a new applicant, e.g., the amount of radiographs to be retained for lifetime has been reduced. Only radiographs required for inservice inspections are to be maintained for lifetime pursuant to ASME Boiler and Pressure Vessel Code require ments. We regard this practice to be as stringent as or more stringent than the practice for other nondestruc tive examination records. Also, the records facility, which previously had to have a four-hour fire rating, now may have a two-hour fire rating provided certain provisions are met. Applicants who are presently committed to imple ment the existing NRC quality assurance regulatory guides and ANSI/ASME
standards and who elect to change and use Revision 3 to Regulatory Guide 1.28 and ANSI/ASME
NQA-1-1983 will benefit somewhat from the examples in the above paragraph, but will encounter additional costs to offset such benefits.
The additional costs will be revising the Safety Analysis Report (SAR) (or quality assurance topical report), quality assurance manuals, and implementing proce dures and retraining personnel to accommodate this change. In addition, considerable time, effort, and resources will be expended in maintaining an account ability of outstanding purchase orders, items, and activities already under way as opposed to new activ ities with respect to the appropriate application of the previous commitment and the new commitment to Revision 3 to Regulatory Guide 1.28. The average SAR revision to accommodate ANSI/ASME
NQA-l 1983 and the revised Regulatory Guide 1.28 would affect about 20 SAR pages and take about 16 staff hours for NRC review and acceptance or approxi mately $960 per plant (16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> x $60/hour).
It would take about 2 staff months for the average utility to review and revise the quality assurance program and implementing procedures to incorporate the revision for a cost of approximately
$25,600 140 days x 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> at $80/hour).
Retraining the plant and corporate staff would cost about $32,000 (400 people x $80/hour).
Therefore, the total cost for the average plant to change to Regulatory Guide 1.28 and ANSI/ ASME NQA-l-1983 would be about $58,560 ($960 NRC fees, $25,600 procedures review and revision, and $32,000 for retraining plant and corporate staff). The total cost to industry, should they all adopt ANSI/ASME
NQA-1-1983 and Revision 3 to Regulatory Guide 1.28, could be in the range of $30,779,520
(79 licensees, 63 permit holders, and 25 nuclear steam supply system suppliers and architect/engineers
= 167 x $58,560 = $9,779,520
and 700 subcontractors x $30,000 = $21,000,000).
4.4 Conclusions In consideration of the above three alternatives, the NRC staff believes Alternative
3 will be the most viable alternative from which to base future quality assurance guidance upon meeting the Commission's regulations relative to quality assurance.
This conclu sion is primarily based upon offering the industry the choices of (1) committing to the N45.2-series stand ards and appropriate regulatory guides that endorse these standards or (2) committing to comply with Revision 3 to Regulatory Guide 1.28 endorsing ANSI/ ASME NQA-1-1983.
In either case, they have the flexibility to develop alternatives meeting the Com mission's quality assurance regulations, regulatory guides, and standards.
5. IMPACTS ON OTHER REQUIREMENTS
As discussed earlier in this Regulatory Analysis, the primary rationale for the proposed revision to Regulatory Guide 1.28 was to consolidate the programmatic stan dards without changing their intent, to eliminate certain redundancies and certain activities, and to reflect certain NRC quality assurance controls considered important by the staff to provide consistency in the quality assurance program review process. These new positions do not represent significant changes in regulatory practices.
The staff has evaluated the guidance included in ANSI/ASME
NQA-I-1983 and, coupled with the guidance included in the regulatory position in Revision 3 to Regulatory Guide 1.28, finds this is equivalent to the guidance, from a programmatic standpoint, contained in the N45.2 series of documents and the regulatory guides that endorsed them. The staff also endorses this consolida tion effort as an acceptable method of meeting the requirements of paragraph
50.34(a)(7)
and Appendix B to 10 CFR Part 50. Consequently, any impact on existing NRC requirements should be minimal.
6. CONSTRAINTS
Legal and institutional constraints, including issues related to enforceability, were discussed in Section 3, "Alternatives."
7. DECISION RATIONALE
7.1 NRC Since current guidance for quality assurance programs is contained in a series of different standards and corresponding regulatory guides, the proposed action will be of value to the staff owing to the consolidation of a large number of requirements and recommendations concerning quality assurance into a single document.
Additionally, consolidation of design- and construction phase quality assurance guidance should provide a more effective evaluation of compatibility between ANSI quality assurance requirements and the quality assurance 1.28-13 requirements in the ASME Boiler and Pressure Vessel Code. By taking advantage of previous staff effort in conjunction with approval of ANSI/ASME
NQA-l-1983, the proposed action establishes an NRC position on the recently approved standard with minimum impact on the staff. .7.2 Industry ANSI/ASME
NQA-1-1983 represents a consensus docu ment on requirements for quality assurance programmatic action agreed to by the American National Standards Institute.
The proposed action establishes an NRC position on an existing national standard and therefore reduces uncertainty as to what the staff considers acceptable in the area of quality assurance requirements for the design and construction of nuclear power plants. 7.3 Public The consolidation of quality assurance criteria could result in more effective reviews of nuclear power plant quality assurance programs.
The consolidation document could also result in improved quality assurance programs at nuclear power plants and hence increased safety for the public since the standard has eliminated certain activities considered to be ineffective in enhancing the overall quality or effectiveness of the quality assurance program. The financial impact on the public will be a slight increase in the cost of generating power as a result of any procedure modifications necessary to comply with this regulatory guide.
8. IMPLEMENTATION
8.1 Schedule for Implementing the Proposed Guidance The methods described in Revision 3 to Regulatory Guide 1.28 (through endorsement of ANSI/ASME
NQA-l-1983 and the ANSI/ASME
NQA-la-1983 Addenda) for complying with the provisions of Appen dix B to 10 CFR Part 50 with regard to the estab lishment and implementation of the requisite quality assurance program are considered to be generally equivalent, from a programmatic standpoint, to the methods described by Revision 2 to Regulatory Guide 1.28 and Regulatory Guides 1.58, 1.64, 1.74, 1.88, 1.123, 1.144, and 1.146 (through endorsement of ANSI/ASME
N45.2 and seven programmatic ANSI/ ASME N45.2-series standards).
Applicants and licensees who have committed to ANSI/ASME
N45.2 and the appropriate ANSI N45.2 series standards as addressed in the applicable regu latory guides may continue to follow ANSI/ASME
N45.2 and the appropriate ANSI/ASME
N45.2-series standards in lieu of ANSI/ASME
NQA-l-1983.
Applicants or licensees may commit to follow the ANSI/ASME
N45.2-series standards or the ANSI/ASME
NQA-1-1983 standard, but not a combination of the two. Since ANSI/ASME
NQA-1-1983 consolidates ANSI/ ASME N45.2 and the seven programmatic ANSI/ASME
N45.2-series standards, these standards will be replaced with ANSI/ASME
Consequently, except in those cases in which an applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described in Revision 3 to Regulatory Guide 1.28 will be used in the evaluation of all new (I) construction permit applications, (2) standard design approvals that can be referenced in construction permit applications, and (3) licenses to manufacture.
8.2 Relationship to Other Existing or Proposed Requirements The proposed Revision 3 to Regulatory Guide 1.28 does not represent an increase in regulatory require ments since it allows present applicants and licensees to continue the use of the N45.2-series standards if they had previously committed to those standards.
