" E""$-84 5.2 Engineering Assurance Department engineer Provides input to the list of topics deserving a comprehensive review, prepares plans and schedules for design process reviews and technical assessments, and resolves coments from South Texas Project Engineering R2 and Licensing Departments on the list of topics selected 6.0 Procedure 6.1 Preparation of a list of review / assessment topics The Manager, Engineering Assurance Department, or his designee shall prepare and maintain a list of topics deserving a comprehensive review.
Every six months this list shall be sent to the Manager, STP Engi-R2 neering, and the Manager, STP Licensing, for review and comment. To establish the review topics and priorities for review, the following guidelines can be used:
6.1.1 Select areas of review that represent the known technical problem areas in the industry.
6.1.2 Select areas that represent critical and complex analysis and design features and areas of known or suspected HL&P and/or con-tractor problems.
6.1.3 Select areas affecting safety, operability, and availability.
6.1.4 Select activities that require significant interfacing with NSSS vendor and other vendors supplying important equipment.
3.1.5 Select areas of analysis and design that provide input to subse-quent design of many systems and components (e.g., seismic analy-sis, sub-compartment and containment pressurization analysis followingapostulatedaccident).
6.1.6 Select representative samples of systems, the design and engi-R2 neering of which are essentially complete, to determine that system design from conception to construction has been carried l
out in a controlled manner.
6.1.7 Select topics for design process review in a manner that ad-dresses the various aspects of the design process (i.e., design input, interface, process, output, and changes) and provides a reasonable assurance of the adequacy of the design process.

6.2 Development of an annual schedule The Engineering Assurance Department staff shall develop an annual schedule for design process reviews and independent technical assess-ments and shall submit the schedule to the Manager, Engineering Assur-ance Department, for approval. Emphasis shall be placed on the topics of importance, and consideration shall also be given to project schedule and effective utilization of the Engineering Assurance staff. The annual schedule shall contain a description of the review subjects, extent of assessment, anticipated man-hours, and start and completion dates for the assessments.
6.3 Review, approval, and distribution of annual schedule The annual schedule shall be reviewed by the Vice President. Nuclear Engineering & Construction, and by other departments or reviewers deter-mined by the Manager, Engineering Assurance Department. After the annual schedule has been reviewed by the Vice President, Nuclear Engineering &
Construction, and approved by the Manager, Engineering Assurance Depart-ment, Engineering Assurance shall distribute the annual schedule to interested or affected organizations, including the South Texas Project
(
Engineering Department.
6.4 Preparation of detailed review / assessment plan and schedule 6.4.1 Design process reviews Design process reviews shall be scheduled and performed by Engi-neering Assurance Department engineers assigned by the Manager, Engineering Assurance Department. The objective of these reviews shall be to develop information by which to judge the adequacy of design controls on the basis of whether the results of the design activities of HL&P and its major contractors are correct and consistent with licensing comitments and represent good engi-neering practice.
In preparing a detailed plan and schedule for l
a review, the following items, as a minimum, shall be addressed:
6.4.1.1 Scope, duration, and detailed breakdown of the review activities 6.4.1.2 Start date and duration of review activities, identiff-cation and collection of documents to be reviewed prior to review, schedule of pre-review meetings, and prepara-l tion of review checklist e-
