2.2 DEFINITICNS 2.2.1 Desian Process - The design process consists of technical and

-management functions whidi connence with the identificaticn of design inputs and conclude with the conpletion of the final design.

2.2.2 Final Design - Approved design output documents or approved changes to tnese documents.

2.3 RESPCNSIBILITIES The Engineering and Construction Manager is responsible for the developnent, i:rplementation and management of design documents.

The Engineering and Construction Manager has specifically delegated the detailed implementation of the design program to the Managers of Cmceptual and Functional Engineering. These Managers shall ensure that engineering design activites are identified, planned and cmtrolled'in accordance with References 1-A,1-B, ard 1-C.

3.1.2 Engineering Procedure and Instruction Personnel within the site organization per 1-D shall establish and inplement procedures / instructions as required to i@lement the design / engineering powcan. Engineering Instructions shall be used to control specific design tasks required by the Engineerirg Procedures. Rese instructions may be for such tasks as design planning, design interface conto 1, design input ard control of design documents. Se instructions shall be prepared, issued and controlled per the provisions of Reference 1-E and 1-F.

3.2 DESIGN INTERFAG CCNTROL 3.2.1 Application Design interface control shall be applied when the design activity of one organization, internal or external, includes or affects the design activity of other organizations. Rese considerations shall normally be defined in established procedures / instructions.

3.2.2 Documentation When an interface has been identified, the following shall be prepared with appropriate mmagement approval.

a. Identification of titles and responsibilities of 'my personnel.
b. Establishment of lines of cxxmunication and controls for the flow of design information and changes.
c. Control and distribution of all documentation.

3.3 EESIGN INPUT Design inputs, epcn which final design is based shall be identified, documented, reviewed and approved on a timely basis. Design inputs shall be detailed enough to provide a omsistent basis for making design decisions, acconplishing design verificaticn and evaluating design changes.

3.4 CCNrRCL CF DESIGN DOCLNENTS Ehgineering procedures and instructions shall outline cbcument control requirements when applicable, such as:

a. Document issue and distribution.
b. Adequate control across design interfaces in accordance with Section 3.3.
c. Assurance that proper cbcuments are identified and available throughout the design program.

3.5 [EFICIENCIES AND NCNCONFORMANCES Significant deficiencies and nonconformances discovered during the design process sucf1 as deviations to the design bases as reflected in FSAR connitments, design errors or deviations from the applicable codes or standards shall be doctmented in accordance with Reference 1-A and 1-G.

3.6 RECORD RETENTICN AND 'IURNOVER

'Ihe originating ceganization/ discipline shall assure that sufficient records are prepared as design work progresses to furnish documentary

( evidence of the quality of the design process and to reflect coupliance with documented Engineering Procedures / Instructions.

Design records required for retention during plant cperation shall be collected, stored and maintained in conpliance with Reference 1-H.
