RANClio SECO QUALITY ASSURANCE PROGRM1
- ., j..
1.-
ORGANIZATION Responsibility for all quality assurance functions associated with Rancho Seco Nuclear Generating Station is assigned to the Office of the Assistant Chief Engineer under the direction of the Quality Assurance Director, as set forth in the SHUD Nuclear Project Organization, Figure 1.
The Quality Assurance Director shall have a direct line of communication to and authority from the Assistant Chief Engineer for the purpose of providing quality assurance direction and quality status of the program.
Bechtel Corporation has been retained by the District as the engineer and construction manager.
In this capacity, Bechtel will perform all quality assurance activities as specified by SMUD's quality Assurance Director. Bechtel's organization is detailed in Figure 2.
2.
DESIGN REVIEW The Rancho Seco Quality Assurance Program includes a system of drawing and specification generation that will include an independent review of all design disclosure documents to assure design adequacy, in-spectsbility, testability, and compatability with the Preliminary and/or ric
- atety Analysis Tcport and inclusion of appropriate quality Assurance provisions.
Bechtel has been retained as the architect engineer to design the facility.
Included in this design effort is a systematic method of independent design review by staff members of the various discipline chief engineers to assure correctness and conformance to the PSAR, FSAR, SMUD, Lechtel, and industry standards.
In cases of major suppliers who have been assigned responsibility for design of Class I items such as B&W on NSS components and systems, SMUD will require an independent design revieu.
SMUD has organized a Project Engineering Group (PEG) which is composed of specialists in the various engineering disciplines associated with the design of a nuclear generating station. They will perform a third independent review of Bechtel and supplier drawings and specifications.
3.
QUALITY ASSURANCE CLASSIFICATIONS All systems, structures,' subsystems, and components are classified so as to establish the degree of Quality Assurance Activity related to their manufacture, erection, installation, maintenance, or inservice inspection.

Classifications shall be confined to two categories defined as follows:
Class I:
A nuclear system, structure, subassembly, component, or design characteristic which, as a result of being defective, could cause or increcse the severity of a nuclear incident which imposes undue risk to the health and safety of the public. All engineered safeguards fall within this category.
Class II: Any system, structure, subsystem, component, or design characteristic which, as a result of being defective, could cause a safety hazard to station personnel, unscheduled reduction in unit output, unit trip, or equipment damage.
All. ass I systems must meet the applicable provisions of the Atomic Energy Commission (AEC) Quality Assurance Criteria for Nuclear Power Plants. Proposed criteria is set forth in the Federal Register, Vol. 34, No. 73, April 17,1969 (10CFR Part 50).
Quality Assurance classifications are established by Bechtel project engineers subject to the approval of Quality Assurance Engineering.
4.
PROCUREMENT DOCUMENT CONTROL All SMUD procurement documents for Rancho Seco shall be reviewed by Quality Assurance personnel to assure incorporation of adequate Quality Assurance provisions. All procurement by SMUD contractors will be con-trolled by Quality Engineering review of contractor purchase orders. This review shall assure that referenced drawings and specifications are to the latest revision and that all applicable codes and standards are noted.
5.
SUPPLIER QUALITY AS3URANCE A system of supp?ier evaluation has been established to assure that sources outside of SMUD provide Rancho Seco materials that are in compliance with specified design requirements and quality standards.
This system includes a program for evaluating Class I suppliers and for providing source inspection as necessary.
6.
INSPECTION PLANNING Inspection activity associated with Rancho Seco will be per-formed to planned, systematic written instructions.
Inspection planning will be prepared by Bechtel office and field engineers subject to the approval of Quality Assurance Engineering.
Inspection planning documents shall become the objective evidence of the quality of the item, operations or tests that were inspected and shall be retained in the Quality Assurance Document Control Center throughout the life of the plant.

CONFIGURATION CONTROL A system of configuration control shall be established to assure that drawing and specification changes are implemented and reflected in facilities, equipment, and materials produced on site or purchased for use on Rancho Seco. The change procedure assures that all changes are processed through Ucchtel and SitUD project engineering as evidenced by signed approvals. The system provides that quality Assurance Engineering controls assure that inspection planning documents incorporate the latest changes.
8.
IDENTIFICATION AND CONTROL OF MATERI AL, PARTS. AND COMPONENTS As part of the Quality Assurance Program, a syst'em of material identification and control has been established that will assure that materials, parts, and components used in Rancho Seco are of the proper configuration, are free of defects and, where necessaty, are traceable to all supporting quality documentation.
A positive system of component or batch identification shall be established which will provide information on configuration and quality status of all Rancho Seco materials received on site. Uhere necessary for inservice inspection considerations or operation requirements, certain items shall be identified in place.
Quality engineering in conj unction with the cognizant job engi-neer shall determine those materials or components that require trace-ability.
Laydown areas, warehousing operation, and material storage areas shall be controlled in such a manner as to assure identification of mate-rials and control of quality.
9.
CONTROL OF SPECI AL PROCESSES Special processes such as welding, cleaning, radiographic inspec-tion, etc. shall be controlled through a system of certification and recertification for personnel and equipment. Quality Assurance Engineering shall be responsible for establishing the necessary criteria for certifi-cation and recertification along with sources of certifying agencies, institutions, special schools, etc.
The SMUD Quality Assurance Director and Bechtel Quality Engi-neering will conduct periodic audits to assure that personnel and equip-ment involved in special processes are properly certified.
10.
RECEIVING INSPECTION A receiving inspection function will be conducted at the site to assure that all Class I materials and equipment are acceptable. This inspec-tion will be accomplished in accordance with written inspection planning documents.

CONSTRUCTION INSPECTION All site construction and installation activities shall be inspected in accordance with written inspection planning documents.
12.
STARTUP TEST INSPECTION All startup activity will be accomplished by a project start-up test group comprising SMUD, Bechtel and B&W Engineering. This group will write cne test specifications and will guide the station operating personnel who in turn will prepare detailed test procedures to be used for startup. The startup tests will be inspected to inspection planning established by the Quality Assurance Engineer.
13.
INSERVICE INSPECTION Inservice inspections will be conducted on the reactor coolant pressure boundary throughout the life of the plant to assure that mate-rials and equipment integrity is adequate for public health and safety.
This inservice inspection shall be monitored by Quality Assurance Inspectors and will follow the guidelines set forth in applicable AS IE/US ASI codes.
14 CALIBRATION OF HEASUREMENT AND TEST EOUIPMENT The Quality Assurance program includes a system of periodic calibration to assure the accuracy of instruments, gages, and measuring i
devices used in the construction and operation of Rancho Seco.
Quality Assurance Engineering shall prepare a calibration manual which contains a calibration procedure for each item or each group of items to be calibrated. Each procedure shall describe the method of initial calibration and frequency of calibration.
15.
HANDLING. STORAGE. SHIPPING. AND PRESERVATION As a part of the design process, the Bechtel design engineer will analyze the finished item to determine the need for special handling, storage, shipping, or preservation requirements. As a part of the design review procedure, the SMUD Project Engineering Group will assure that provisions have been made in the drawings or specifications for any special handling, storage, shipping, or preservation requirements.
The Quality Assurance Engineer will incorporate these special requirements in inspection planning documents to assure inspection verification that they are met.
16.
INSPECTION. TEST AND OPERATING STATUS A system of stamping and tagging will be used to indicate quality status. Three stamps will be employed: a round acceptance stamp, and "R" shaped reject stamp to signify nonconforming items,and i
a "C" can ce l s t amp.
Three tags will be used:
a green accept tag, a yellow hold tag for materials awaiting further quality verification, and a red reject tag for nonconforming items.
Control of stamps and tags are under the direction of the S:!UD Quality Assurance Director.
17.
NONCONFOR TING !!ATERIAL CONTROL All nonconforming material will be segregated from acceptable material, documented on an inspection report and dispositioned by proper authority.
Rejected material will be promptly segregated by moving the item to a clearly quarantined salvage area.
J A vigorous corrective action program will constitute an integral part of the nonconforming material control system.
Records will be retained on all nonconforming material indi-cating ultimate disposition of material--Accept As Is, Rework, Repair, or Rej e ct.
Accept As Is or Repair dispositions vill be approved by an Engineering Review Board comprised of representatives from Quality
~
Assurance Engineering, Bechtel Project Engineering and SMUD Project Engineering.
18.
DOCGtENTATION COSTROL CENTER A Quality Assurance Documentation Control Center will be main-tained on the site for the purpose of establishing a central point for controlling all records that represent objective evidence of the quality status of all aspects of the Rancho Seco Nuclear Generating Station.
The Documentation Control system shall permit rapid retrieval of quality documentation supporting any object of Rancho Seco construction.
All documentation shall be reviewed for completeness by Bechtel Quality Engineering prior to filing in the Documentation Control Center.
