""' W N -84 6.0 Procedure 6.1 The Manager, Engineering Assurance Department, identifies the topics to be reviewed and/or assessed and also determines the responsible Engi-neering Assurance Department engineering personnel to provide necessary technical review of the topic selected.

6.2 For design process reviews the following procedure shall be followed:

6.2.1 Each discipline engineer shall prepare a checklist pertinent to the subject being reviewed; Attachment 7.2 is an example of such R4 a checklist. The completed checklist shall be filed in the Engi-neering Assurance Department file as well as in the South Texas Project Records Management System (STP RMS) but need not be part of the design process review report.

1 6.2.2 Each discipline engineer shall prepare a complete list of docu-ments to be reviewed.

6.2.3 The Manager, Engineering Assurance Department, or his designee shall hold a pre-review meeting with the affected organiza-l tion (s), identifying the scope of the design process review and outlining major subject areas to be reviewed.

The responsible engineer shall document the results of the design lR4 6.2.4 process review, complete the checklists, including any additional items deemed necessary for a particular design process review, and prepare the design process review report per Engineering Assurance Department Procedure EAD-4, Reporting of Design Process l

Review / Technical Assessment Results.

l l

6.2.5 The Manager, Engineering Assurance Department, or his designee shall discuss the results of the design process review with the R4 affected organization in a post-review meeting, the minutes of l

which will be published after the meeting.

6.2.6 The Engineering Assurance Department shall forward the design l

process review findings to the Vice President, Nuclear Engineer-ing & Construction, for review and approval.

6.2.7 After the design process review findings have been reviewed by l

the Vice President, Nuclear Engineering & Construction, the Engi-l neering Assurance Department shall notify the affected organiza-tion of the findings.

6.3 For independent technical assessments, the following procedure shall be followed:

6.3.1 Each discipline engineer shall prepare an assessment checklist pertinent to the subject being reviewed; Attachment 7.1 is an R4 example of such a checklist.

6.3.2 The responsible engineer shall prepare a complete list of docu-ments required for design assessment and shall infonn the project of the schedule for receiving the documents.

6.3.3 The Manager, Engineering Assurance Department, shall hold a pre-assessment meeting with the affected organization (s), identifying the scope of the assessment and outlining the major subject areas l

to be assessed.

l 6.3.4 The responsible engineer shall document the results of the assessment, complete the checklists, and prepare an assessment lR4 report per Engineering Assurance Department Procedure EAD-4, Reporting of Design Process Review / Technical Assessment Results.

The completed checklist and questionnaire shall be filed in the Engineering Assurance Department files as well as in STP RMS but need not be a part of the report.

l.

6.3.5 If a calculation is generated by an outside organization and the Engineering Assurance Department responsible engineer only reviews the calculation for independent technical assessment purposes, the responsible engineer may incorporate a summary statement for deficiencies in the calculations, if any, and other pertinent observations.

6.3.6 The Manager, Engineering Assurance Department, or his designee shall discuss the results of the assessment with the affected organization in a post-assessment meeting, the minutes of which R4 will be published after the meeting.

6.3.7 The Engineering Assurance Department shall forward the assessment findings to the Vice President, Nuclear. Engineering & Construc-tion, for review and approval.
