SUMMARY

The Nuclear Regulatory Comission (Comission) is proposing to develop regulations requiring enhanced acceptance procedures including, but not limited to, receipt inspection and testing of products purchased for use in nuclear power plant structures, systems and components.

This Advance Notice of Proposed Rule-making (ANPR) is intended to solicit coments on the need for additional regula.

tory requirements and to obtain an improved understanding of alternatives to regulatory requirements that could provide assurance that structures, systems and_ components procured for use in nuclear power plants will perform as expected to protect public heslth and safety.

DATE: The comment period expires July 5,1989.

Coments received after this date will be cor.sidered if it is practical to do so, but assurance of consideration cannot be given to comments received after this date.

SUPPLEMENTARY INFORMATION:

Background

Appendix B to 10 CFR Part 50 of the Commission's regulations adopted in 1970 (35 FR 10498) establishes the quality assurance criteria for safety-related structures, systems and components for nuclear power plants.

The purpose of the quality assurance criteria in Appendix B is to provide requirements for the design, procurement, receipt inspection and testing, construction and operation of nuclear power plant structures, systems and components. The criteria are generally structured to confirm the quality of products designed, purchased, inspected, tested and installed for use in nuclear power plant structures, systems and components. The criteria apply to all activities conducted during the design, construction and operating phases of nuclear power plants that affect the safety-related functions of structures, systems and components.

Procedures and actions by licensces and their representatives

~

I conforming to these criteria are expected to detect substandard and p'oor quality products but may not necessarily detect counterfeit or fraudulently marketed l

products.

Recent cases involving apparently substandard, counterfeit and Ie-_-____________-______

i 1

7590-01 fraudulently marketed products for nuclear power plant structures, systems and components have prompted the Commission to reconsider the adequacy of current regulations for detecting substandard, counterfeit and fraudulently marketed products and for assuring that such products are not used in nuclear power plant structures, systems and components.

Criteria III, IV, VII, VIII, and XV of Appendix _B to 10 CFR Part 50 provide the criteria for the control of purchased structures, systems and components for nuclear power plants. Historically, licensees and their representatives have purchased products with certifications attesting to the quality of the products and have depended to varying degrees on the certifications as one basis for accepting the products. However, recent discoveries of substandard, counterfeit and fraudulently marketed products furnished to nuclear power plants by con-tractors and subcontractors demonstrate that current product acceptance practices, particularly those based heavily on certifications and stated catalog specifica-tior,s, have not been sufficient in all cases. Additional details of apparently substandard, counterfeit, and fraudulently marketed products are cor.tained in NRC Compliance Bulletin No. 87-02 and Supplements 1 and 2, NRC Bulletin No.

88-05 and Supplements I and 2, NRC Bulletin No. 88-10, NRC Infonnation Notice No. 88-19, NRC Information Notice No. 88-35, NRC Information Notice No. 88-46 and Supplement 1, NRC Information Notice No. 88-48, and NRC Information Notice No. 88-97.1 1 These documents are available for inspection at the Comission's Public Docu-ment Room, Gelman Building, 2120 ! Street, NW, Washington, D.C.

7590-01 In many cases, as in part discussed in the referenced bulletins and information notices, product acceptance practices have failed to detect such substandard, counterfeit or fraudulently marketed products.

Therefore, the Comission is considering the need fcr additional regulations or other methods to provide additional assurance that products purchased for use in nuclear power plant structures, systems and components satisfy requirements and specifications that are imposed to provide confidence that these items will perfom as required to protect the public health and safety.

The Comission's regulations provide two alternative approaches to assure that structures, systems and components satisfy requirements for safety-related appli-cations. A licensee may procure products to the requirements of the applicable code or standard for the safety-related structure, system or component.

Alter-natively, the licensee may purchase a commercial grade product and then, using the appropriate procedures and satisfying the Comission's requirements, dedicate the comercial grade product for the safety-related application. The experiences that have been discussed in the bulletins and information notices previously referenced apply to products that were obtained using both of these approaches.

The Comission has concluded that significant engineering involvement is required during the procurement process for products used in nuclear power plants and during any testing of these products.

It is the Comission's view that, in the past, inadequate engineering involvement has been a comon weakness in licensees' i

procurement programs, particularly when comercial grade procurement were involved.

It is the Comission's position that involvement of a licensee's engineering staff in the procurement process should include (1) selection of

.v.

7590-01 products to be used in the plant, (2) determination of the critical characteristics of the selected products that are to be verified during product acceptance, I

I (3) determination of specific testing requirements applicable to the selected i

products, and (4) evaluation of test results. This involvement should be appli-cable to products initially procured as safety-related as well as comercial grade products procured for dedication and upgrading for use in safety-related applications. The extent of this engineering involvement will be highly dependent on the nature and use of the products involved.

The Comission is concerned about the quality of commercial grade products that are used throughout the nuclear plant, including applications in the " balance of plant" structures, systems and components.

This concern stems from a recogni-tion that structures, systems and components utilizing substandard products may not function as designed and may challenge safety-related systems unnecessarily or complicate the response to off-normal events.

Comenters are requested to consider the issues and questions in this ANPR as they may relate to the need or desirability for either more prescriptive regulations or, alternatively, a perfonnance-based requirement.

Comments are also requested on the desirability of any such requirement for safety-related applications, as well as for applica-tions throughout the plant.

A broad spectrum of issues needs to be considered before the Comission decides on the scope and content of any proposed new regulatory requirements addressing the concerns raised by the experience of licensees placing essentially complete reli-ance on certificates, such as Certificates of Compliance, and the evidence that

7590-01 i

some contractors are misrepresenting products. This experience is discussed in the referenced bulletins and information notices.

The following questions are posed to raise the issues that the Commission has identified and are not to be considered complete nor are they intended to bound the scope of public coment on this ANPR. The questions are structured in two categories:

(1) Products Procured for Use in Safety-Relatec Structure, System and Component Applications, and (2) Dedication of Commercial Grade Products for Use in Safety-Related Struc-ture, System and Component Applications.

Public comments are invited on each of these questions.

The comment resolution process will be improved if each comment is identified to the question to which it responds.

Commenters may submit, in addition to the original paper copy, a copy of the letter in an electronic format on IBM PC-DOS compatible 3.5 or 5.25 inch double sided double density (DS/DD) diskettes.

Data files should be pro-vided in ASCII code or, if formatted text is required, data files should be pro-vided in IBM Revisable-Form Text Document Content Architecture (RFT/DCA) format.
