Title:
PREPARATION OF CifCKLISTS Revision: 3 (D
U l.0 PURPOSE This procedure specifies the requirements for preparation of design document review check!!sts to be used in the performance of the CPSES Design Adequacy Progrom (DAP).
2.0 SCOPE This procedure applies whenever a design document review checklist is required by a Discipline Specific Action Plan, o DAP procedure, or through a Discipline Instruction issued by the Review Team Leoder, Design Adequacy Program Manager, or Discipline Coordinator.
3.0 DEFINITIONS AND RESPONSIBILITIES 3.1 Definitions 3.1.1 Criterion A criterion is any statement of a performance, design feature, or design requirement which a system, structure, or component must meet in order to be capable of performing its design function or to be in compliance with a project requirement or commitment.
3.1.2 Commitment A commitment is any statement made by the project as part of the public record which identifies a system performance requirement, design feature, or design requirement which will be met by the project.

3.l.3 Implementing Document i
implementing documents are design documents (such as calculations, evaluations, 1 ond analyses) that translate design criteria into design output documents.
3.1.4 Output Document Output documents are design documents (such as drawings and specifications) that define technical requirements of systems, structures, and components.
3.2 Responsibilities 3.2.1 Checklist Developer Checklists shall be developed by personnel assigned by the Discipline Coordino-tor. The Discipline Coordinator may also be a checklist developer.
O 3.2.2 Discipline Coordinator The Discipline Coordinator shall assign personnel to develop checklists. He shall define the purpose and scope of each checklist. This definition may be in the form of verbal direction to checklist developers.
4.0 INSTRUCTION 4.1 Evoluotion Design Criteria and Review Topics Checklists will be prepared to ensure a consistent and complete review of design criteria for the various review topic areas. Design criteria review checklists shall be prepared using the format of Attachment A for each design discipline TN-85-6262/4 Page 2 of 7

review topic area to verify that the review topic criteria are complete, consistent, and adequately defined. Design review summary checklists shall also !
be prepared using the format of Attachment B to summarize the verification of the implementation of the review topic criteria. Where appropriate, the Discipline Coordinator may allow more than one review area to be evaluated on a single checklist (Attachment A or B). The Discipline Coordinator may authorize alternatives to the format of Attachments A and B; however, the olternative format shall contain comparable information. The Discipline 1 Coordinator shall maintain a log of checklists used in the format of Attachment G to this procedure. This log meets the requirements of DAP ll and be filed in accordance with DAP 14.
4.2 Preparation of Checklists Unless otherwise directed by the Discipline Coordinator, Design Criteria and G Design Review checklists shall be prepared in occordance with the format of Attachments A and B for the various review topics. The Discipline Coordinator shall assign one or more individuals to the preparation and completion of the checklists. The Discipline Coordinator may develop checklists.
A Design Review Evoluotion form is prepared for each review topic in accor-dance with the format of Attachment C. The criterio/ commitments (from the list developed in accordance with DAP-1) opplicable to the topic are reviewed and selected for inclusion on the checklist. The checklist preparer may select fewer than 100 percent of the opplicable criterio provided that the bases for such selection are documented'as on ottochment to the Design Review Summary form. Where o criterion / commitment listed in the criterio/ commitments list is itself a source of criteria that is not expanded upon in the list, the checklist TN-85-6262/4 Page 3 of 7

PREPARATION OF CECKLISTS Revision: 3 O should use detailed criterio extracted from that source. Where fewer than 100 percent of the opplicable criterio/ commitments are used, the bases for the selection of specific criteria shall be documented as on ottochment to the Design Review Evoluotion. * ' e selected criterio/ commitments (including more detailed criteria obtained from the source document) are entered in the " Attributes Reviewed" column of Af tochment C.
The " Description of Verification" column of Attachment C shall be completed to describe the method by which implementation of the criterion will be verified (e.g., line-by-line check of a calculation, comparison of selected calculation pages against selected drawings, etc.). If necessary, this column may be cross-referenced to on ottochment that contains more information on the verification methodolgy. If the criterion itself does not represent odequate acceptance criteria for the review the description of verification column shall contain this information.
) Specific documents to be reviewed are selected in accordance with DAP-21.
Where appropriate, development of the Design Review Evaluation form and the selection of specific documents may proceed in parallel if necessary to ensure the adequacy of the checklist form. In addition, the person preparing the Design Review Evoluotion form should also give consideration to the following factors:
o Whether similar document type.4 exist such thot a combi-nation of document types is mieded to reach c conclusion about the odequacy of a portion of the design process (e.g., there may be eight types of mechanical calculations and selecting one of each type, as required above may provide on odequate test of the calculation process, such that no significant benefit is gained from testing multiple examples within each type) o Whether the criteria that could be verified by additional examples of the document type con also be verified by other document types or through other means (e.g., by comparison with pre-operational test results).

l 4.3 Additional Checklist items in addition to the speelfic checklist items extracted from the criteria / commit-ments list, the checklist developer shall consider the items in Attachments D and E and shall incorporate them into the checklist os determined to be appropriate by the checklist develcper and the Discipline Coordinator. In considering these items (which are defined in ANSI N45.2.ll-1974, Section 6.3.1), the developer and Discip!!ne Coordinator shall take into consideration that not all items are opp!!coble to each document type, that other aspects of the review may odequately oddress these topics, and that the wording of the item may need to be clarified for use in the checklist.
4.4 Approval of Checklists Formats Each Discipline Coordinator shall opprove all checklist forms developed for his discip!!ne. This approval requirement applies to design review evaluation forms (whether in the format cf Attochment C or in an citernative format), to checklist forms that are used as alternatives to Attachments A and B (Discipline Coordinator approval of Attochments A and B is not required), and to any other checklists developed for his discipline. The opproval of the Discip!!ne Coordino-for to use a checklist form shall be in the form of a memo to appropriate personnel authorizing them to use the forms noted in the memo. Supplemental attributes added to o checklist form in occordance with Section 4.5 below shall not require Discipline Coordinator approval prior to completion of the checklist.
4.5 Use of Checklist Other DAP procedures and discipline Instructions govern the use of checklist forms developed in occordonce with this procedure. Prior to using any checklist form to conduct a review in occordance with a procedure governing its use, the person intending to use the checklist form shall assure himself or herself that the TN-85-4262/4 Page 5 of 7

Title:
PREPARATION OF CHECKLISTS Revision: 3 O checklist form is odequate for its intended purpose, in particular, the user shall consider whether any item on Attachments D and E should be odded to the checklist form. Furthermore, the reviewer may odd any additional attributes that he or she feels is necessary to ensure the adequacy of a design review evoluotion form (Attachment C or equivalent). Such additional attributes or other checklist form supplements may be added without prior Discipline Coordinator opproval. Discipline Coordinator opproval is achieved when the completed checklist is approved.
5.0 DOCUMENTATION 5.1 Identification Of Checklist Forms Design review evoluotion checklist forms (i.e., checklist forms similar to the format of Attachment C that contain the review attributes, but which have not been used for o review) shall be given a checklist form number, revision number, j } and date. The checklist form number shall be placed in the lower right hand corner of each page of the form if Attachment C is used; otherwise the checklist form number may be placed where it is deemed appropriate by the Discipline Coordinator. The initial version of each form is designated "Rev. 0".
The format of the checklist identificotton shall be:
