.- 8/29/78 2.0 Responsibilities and Requirements

Material and equipment required in the operation and maintenance of TVA's

d. nuclear plants are purchased by the Division of Purchasing. Purchase specifications prepared by the originator of a request form the basis of

'- the contract between TVA and the supplier. A Contracting Officer is named for each contract by the Division of Purchasing. The Contracting Officer is responsible for assuring that provisions of the contract are met. All technical interpretations cre made by the organization which h originates the specifications. Contracts are awarded only to qualified ma'ufacturers. Contracts provide access by TVA inspectors to areas of a manufacturer's plant and access to any associated records when a

' source inspection, audit, or surveillance is planned.

2.1 Preparation of Purchase Requests All items of the critical structures, systems, and components as

- identified in Appendix A of this manual shall be considered to require quality assurance surveillance.

The primary responsibility for initiation of quality assurance requirements in the procurement of materials, components, and spare parts rests with the originator of the purchase request.

He is responsible for assuring that regulatory, code, design basis,

. _ _ and other requirements are properly included or referenced in the request.

9 The originator of each request for material, components, or spare parts within the scope of the operational quality assurance program shall be familiar with the function of the system for which he is ordering material; with the importance of the material

_ or equipment to be ordered to plant safety; and with the applicable codes, standards, criteria, design bases, and regulatory require,ments.

The request shall include those quality assurance requirements consistent with the importance of the purchased material or equipment

~

to plant safety. -

The appropriate section supervisor is responsible for notifying

- Power Stores of any changes which would affect the reorder of stock

.tems.

- The intent of these requirements shall be to procure material ~ and equipment equal to or better than that utilized in the original design and construction of the affected system.

-- 2.2 Assignment of Quality Surveillance Levels Purchases of items for nuclear plants are divided into two general ,

categories. Items for general use not related to critical structures, I

~'

systems, or components shall be purchased through regular procurement 8

, channels that do not involve the assignment of nuclear quality assurance. requirements. Noncritical structures and equipment are 4dentified in Appendix A of this manual.

. Materials, components, and spare parts purchased for installation --

in the critical structures, systems, and components shall be purchased through unique channels established to ansure that nuclear quality assurance requirements have been satisfied. To provide for uniform interpretation of regulatory requirements and to assist those charged -

with the responsibility of ordering materials, components, and spare parts, the Division of Nuclest Power has adopted the following policy which is intended tq be specific and practical.

Materials, components, and spare parts which will become part of the S

['

critical structures, systems, and components shall have assigned to the purchase request one of four levels of quality assurance surveil- ,s lance. Assignment and application of one of the four levels shall be to assure quality of a purchased item to an extent consistent with its -

importance to nuclear safety. Also, the packaging and shipment of -

these items shall be commensurate with their importance to nuclear safety. __

The originator of the purchase request is responsible for assignment ,,

of the appropriate level. ,

The four levels of quality assurance surveillance are described in detail in the following paragraprm.

2.2.1 Level I Level I quality assurance surveillance shall be assigned to: (1) those materials, components, and spare parts which --

are a part of and whose failure would violate the reactor coolant pressure boundary; (2) those other CSSC items that cannot be bought by industry standards or reference -

part number; and (3) certain items that must be specifically

~

bought as Level I and are so defined in DPM No. N76A10.

The reactor coolant pressure boundary is a part of the critical structures, systems, and components. Attachment 1 .

of this spare parts procedure defines the reactor coolant

11/24/78 4.0 Quotation and Bid Review and Award Quotations and bids by manufacturers are reviewed by Power Stores and the originator, if requested, to ensure that no exceptions are taken. Exceptions which may affect quality shall be accepted only after being subjected to the same review / approval cycle as the original procurement document. The speci-fication requirements and the manufacturer's quality assurance plan -1.all be reviewed with the manufacturer when necessary to be certain that he under-stands all requirements and that his quality assurance program fulfills specification requirements. Awards are made only to qualified manufacturers.

The determination that vendors are qualified is usually based on TVA audits, audits by others (e.g. , NRC, ASME, or CASE), review of the vendor's per-formance history, or by review of the vendor's QA manual. Detail requirements for evaluating the qualification of vendors are found in DPM No. N76A10, Appendix 5. After award of the contract, assessment of the effectiveness of quality control by the manufacturer and other suppliers shall be made at intervals consistent with the importance, complexity, and quantity of the product. Such assessment by P PROD shall be based on test reports, reports of inspections at the manufacturer's facilities, audit reports, receipt inspection reports, or other evidences. Corrective action shall be taken where needed.

5.0 TVA Certification or Manufacture TVA may elect to accept responsibility for originating quality assurance

ocumentation in the purchase of materials, components, or spare parts when documentation required from the supplier is either not available or excessively expensive, or causes undesirable delay in delivery. TVA shall provide adequate testing and certifying facilities to supply the necessary quality assurance documentation.

TVA may manufacture, repair, or recondition materials, components, and spare parts for use in the critical structures, systems, and components.

Adequate production, testing, and certifying facilities shall be available and quality assurance documentation shall be supplied. The originator of the request shall specify the appropriate quality assurance surveillance ~

level and the documentation to be supplied.

6.0 Certification Bv Outside Agencies TVA may contract with an outside agency for quality assurance documentation 3 in the purchase of spare parts. For example, a contract may be arranged with the primary nuclear steam system supplier to provide quality assurance E

services covering spare parts purchased from this supplier or its subcontractors, t

Quality assurance levels will be assigned as described ab ve; however, for QA Level I items, the originator of the pucchase request need not list the specific doc entation and engineering specification requirements if the spare and replacement items are to be provided in I accordance with the supplier's quality assurance program which assures that the items are equal to or better than the original items. The P PROD Quality Assurance Staf f shall make certain that the prime supplier is periodically audited to assure his quality assurance program is properly implemented.

8.0 Modification Materials .

When materials are procured for work covered by an approved ECN, the material specifications given by EN DES on the engineering drawings shall be included in P PROD procurement documents.

Part III Sec. 2,1 N-OQ/sM Revised I DEFINITION - Reactor Coolant System 10/18/7h I "The reactor coolant system is that system which contains primary reactor coolant at operating pressure during nomal reactor operations." (Footnote 2, Page 2, Para.15-120,Section XI, of ASME Boiler and Pressure Vessel Code,1971 I .

Edition.)

DEFINITION - Reactor Coolant Pressu're Boundarv.

I " Reactor coolant pressure boundary means all those pressure-containing components of boiling and pressurized water-cooled nuclear power reactors, such as pressure vessels, piping, pumps, and valves, which are: .

(1) Part of the reactor coolant system, or I (2) Connected to the reactor coolant system, ~o to and including any and all of the following:

(i) The outemost containment isolation valve in system piping which penetrates primary reactor containment, I -

(ii) The second of two valves nor ally closed during nomal reactor operation in system piping which does not penetrate primary reactor containment, (iii) The reactor coolant system safety and relief valves.

For nuclear power reactors of the direct cycle boiling water type, the reactor coolant system extends to and includes the I outemost containment isolation valve in the main steam and feedwater piping." (10 CFR 50.2)

INTERPRETATION - Reactor Coolant Pressure Boundary "The scope of these rules covers the strength and pressure integtity of the structure of pumps and valves whose failure I would violate the pressure boundary. They are not intended to be applicable to valve operators, controllers, position indicators, pump impellers, pump drives or other accessories I and devices, unless such items themselves are pressure parts.

These rules provide requirements for new construction. They cove,r mechanical and themal stresses but do not cover I

deterioration that may occur in service as a result of corrosion, radiation effects, and instability of material."

(Draf t ASME Code For Pumps and Valves For Nuclear Power, November 1968, Paragraph 110.) (1971 ASME Boiler and Pressure I Vessel Code,Section III - Nuclear Power Plant Components; Paragra;Qs NA-ll10, NA-ll20, NA-1130, and NE-1141 restate the above Pump and Valve Code concepts for Nuclear Power Plant '

Components.)

I

Page 12 Part III Sec. 2.1 N-04N4 f(r vine d lo/ll!/'/ sl TVA INTERPRETATION - Violation of Reactor Coolant Pressure Boundary The following statements reflect TVA's specific interpretations of the intent of codes, standards, and regulations concerning the meaning of the phrase " violation of the pressure boundary" as used in connection with specifying quality assurance I requirements in the procurement of materials, 3 components, and spare parts covered by this p rocedure.

~

A. Failure of a pump or valve to perform its intended function does not necessarily constitute a violation of the pressure boundary.

B. Leaks associated with packings, gaskets, seals, and seats do not constitute a violation of the E pressure boundary. 3 .

C. A violation of the reactor coolant pressure g boundary e: ists when a fluid retaining component g within the li: sits of the pressure boundary as defined on page 11 of this procedure fails to perform its fluid retaining function to the extent that normal pressure or flow associated with that l

a component is significantly affected or technical specification limits are exceeded.

D. A violation of the reactor coolant pressure , boundary exists when a fluid retaining component such as a a pump, valve, or pipe within the limits of the pressure boundary as defined on page 11 of this - I procedure fails and results in a radiation hazard to either the plant personnel or the general public I in excess of the limits of exposure or permissible 5 levels.as set forth in 10 CFR 20 or other applicable regulations.

SUPPLEMENTARY NOTES - 1. Although not strictly included in the definition of pressure boundary, Ldvel I quality assurance surveillance has been assigned in this procedure to the purchase of pump impellers and shaf ts and valve discs. Level I surveillance may be assigned to other items of this nature as determined by l the originator of the purchase request. E o

Part III Sec. 2.1 N-OQAM Revised I

10/18/74

2. Page 12 of this procedure, Violation of Reactor Coolant Pressure Boundary, addresses to the meaning of the word " violation." There is no intent to I modify or extend the definition of " pressure boundary" as noted on page 11.

I 3. A flow check valve is an isolation valve (TVA G-28 appendix A, class A) .

4.

I TVA General Construction Specification G-28, Construction of Piping System For Boiling Water Reactor Nuclear Plants, provides for classification of piping systems in classes ranging from class A I through class N. Quality assurance requirements are identified as applying to class A, B, C, D, and E piping systems by General Construction I Specification G-27. The piping classification assigned to each section of line is identified on various piping drawings. Repair or replacement piping should satisfy requirements at least I equivalent to that specified for the original pipe.

5. B 31.7, Nuclear Power Piping, does not cover piping 1 inch or smaller, therefore, " class A" does not cover piping 1 inch or smaller, however in some instances, TVA drawings show an assignment of class A to some 3/4-inch lines.

6. Design criteria or specifications, as built. shop drawings, and other records should be available I to the originator of a purchase request which identify, by number, ASTM specifications for stedl piping. Individual ASTM standard specifications I contain detailed instructions for writing purchase orders for the purchase of piping to these ASTM specifications.

E 8/2/78 (a) Level IS--Level IS shall be assigned to services which affect the integrity of the reactor coolant pressure boundary. Procurement documents for such services shall contain or reference detailed specifications. Contractors providing such services shall be

required to provide and maintain a quality assurance program which addresses the pertinent elements of 10 CFR 50, Appendix B. The contractor's work shall be performed in accordance with detailed procedures which shall be approved by TVA prior to performance of the work. Only qualif,ied contractors (see paragraph 4.0) may be used to provide services which have been assigned level IS.

(b) Level IIS--Level IIS shall be assigned to CSSC-related services which will not affect the reactor coolant pressure boundary and cannot be subsequently verified by inspection or tests. Such services may be procured only from qualified contractors. The ,

contractor may be required to maintain a quality assurance program depending on the complexity and importance to safety of the services .

being provided.

(c) Level IIIS--Services may be assigned level IIIS if they are CSSC-related but do not involve the reactor coolant pressure boundary and if they are relatively simple, standardized services (such as machining a shaft) which may be adequately verified through acceptance inspections, tests, or reviews. Only services which have been evaluated and '

specifically permitted in advance may be assigned this level. '

Generally, special quality assurance requirements are not required for level IIIS services. No special investigations of the contractor's qualifications shall be required for level IIIS services. E g

(d) Level IVS--Level IVS shall be assigned to services which are related to the CSSC but which are deemed to have no safety-related implications.

This level shall require no special quality assurance requirements. l E

4.0 Qualification of Prospective Contractors ~

Services assigned levels IS and IIS may be bought only from contractors -

whose qualifications have been evaluated and approved by the P PROD Quality Assurance Staff. This evaluation shall be based on the same kinds of informatior as described in DPM No. N76A10, Appendix 5, with one xception. This exception is that suppliers of level IIS services m..y be qualified based solely on TVA's or other users" past experiences with tre contractor. When this input is used, information concerning the source of the input and specific comments about the contractor's past performance shall be documented.
