- 1. General In octorher, 1990 Toshibs was performing preliminary engineering and testing work on the sawa program. We 04 program specific to this preliminary sBNR work was developed and documented at that time although Toshiba was generally proceeding with the 83WR project according to its general QA codes and procedures. As Toshiba efforts on the 83WR progrased to support the final 88WR design,
, the appropriate QA program Quality Assurance for $3NR" procedures documents werenasurance the qualit applied.
This program that is applied to all final design war performed by Toshiba on the 85WR program since Octorber, 1990 and meets the requirements of JEAG-4101-1990. This program is also intended to be consistent with the applicable portions of NQA-1-1983 ana MQA-la-1983.
This program describes the basic program of total qual-ity assurance activities that nuclear Energy Division 1 (NED), Toshiba corporation shall perform for eBWR that j meets the applicable regulatory requirements, codes, and i standards.

SEP.15'94' 4:55PM GE NUCLEAR BLDG J E9892 P ll/16 Divisions and Laboratories are responsible for aneuring that practice does not differ from the basic plan, includ-ing work approvals, from the detailed design implementa-tion stage.
2.5 The communication channels The overall representative for SSWR QA and the communi-cation channel for all QA matters shall be the manager of QA Department. The channels for communication of engineering matters shall be the managers of each-engineering department or design department, for their respective areas of responsibility and the General Manager of NuclearEngineering Laboratory for reserch and develop-ment.
- 3. Document control The documents used for SEwa are classified into the following three groups ,
- a. Laws, regulations, and standards
- 5. Documents to be received from CE
- c. Documents to be prepared by NED These documents shall be controlled as follows:
(1) control of Laws, Regulations, and Standards Laws, regulations, and standards applicable to I design, fabrication, incpection, and test including JEAG-4101-1990 shall be provided, maintained and updated by each design and engineering department and quality assurance department.
(2) control of Documents to be Received from GE The received documente shall be controlled and followed up by each design and engineering depart- I ment. Iowever, overall control for receipt / response date, document number, response conditions and others shall be done by NED Project Engineering Department.
(3) Control of Documents to be Prepared by EED l
The lists which specify the type of documente for l preparation of the documents shall be provided in I order to control and follow up preparation of these documente. The lists are to be controlled by NED Projects Engineering Department.
The documents prepared by each department shall be controlled by each section manager in the each department who approves prepared documents.

- 4. Design Control In order to clarify and correctly reflect the design requirments such as applied laws, standards, . codes con-corning quality in the design documents, each department shall be roepensible for design verification, design -,
change control, and design interfaea contral. l 4.1 Design Verification (1) According to the degree of importance of the struc-tures, systems and equipment, suitable control methods shall be established for verifying the validity of the design. Design verifications shall be performed and their results shall be documented.
(2) Depending on the operating experiences including deficiencies and failures of similar facilities, equip-ment, and the state of the art of manufacturing tech-niques, design verifications shall be perfomed for new designe, new materials, and and new teobnology.
(3) By using design document review,_ alternate calcula-tions, and testing'as the verification methods, design verifications shall be performed. The verifier shall be a person who did not do the original design.
(4) Design analyses shall be performed in a controlled manner and documented in appropriate design record files or other files for retention as quality records.
computer oodes used for design analyses shall be controlled and the resulta verified to assure valid solutions to sorrently modeled physical problems.
Appropriate records of computer modeling and' design calculation for SENR shall he retained.
. 4.2 Design change (1) In the case of design change, the reason shall be clearly documented.
(2) Design changes shall be carried out by the same i design control methods as those applied to the original '
designs.
(3) In the case of design change, the effects on the design of not only the internal organisation but also the associated comptaies shall be verified.
(4) The preparation, approval, issuance, and distribu-tion of revised documents shall be controlled properly.
4.3 Design Interface control The design interfaces between departmente and within each department shall be clearly established and docu-mented.
