Project Management Overview Houston Lighting & Power Company (HL&P), acting as PROJECT MANAGER for itself and the other owners, City Public Service Board of San Antonio, City of Austin, and Central Power and Light Company, has responsibility for design, engineering, procurement, fabrication, quality assurance, construction and, operation of the South Texas Project. HL&P has contracted with Westinghouse Electric Corporation (Westinghouse) for the design, fabrication and quality assurance (QA) services for the nuclear steam supply system, and with Bechtel Power Corporation (Bechtel) for plant design, procurement, engineering, con-struction management, QA and other related services including OA services for Westinghouse items upon receipt at the Project site.

HL&P has contracted with Ebasco Services Incorporated (Ebasco) for construction services including 0A and quality control (QC) for its scope of work.

Figure 1 shows the organizational structure and functional relationship among HL&P, Bechtel and Ebasco for the four major functional areas: 0A, Engineering, Construction, and Controls.

Project direction is provided from the HL&P Manager, South Texas Project, to the Project Manager of Bechtel. The HL&P Project organizations provide a performance overview of the respective Bechtel Project organizations.

Bechtel, as Construction Manager, directs the activities of Ebasco and performs a QA overview of Ebasco activities. Bechtel is responsible to assure that all Balance of Plant systems meet the NSSS interface requirements. Bechtel is also responsible for any necessary techni-cal review of the NSSS equipment and associated support services. HL&P project management provides programatic overview and direction relative to the Bechtel-Westinghouse interface.

The current internal organizational structures of HL&P, Bechtel and Ebasco for the South Texas Project are shown in Figures 2, 3 and 4, respec-tively.

Although there may be modifications to these internal structures, the functional relationships between the respective organizations will remain as indicated by Figure 1.

II, Quality Assurance The QA Program for STP is described in the Ouality Assurance Program Des-cription, Revision 3 (QAPD), which was submitted to NRC by letter dated March 9, 1982. Figure 5 shows key aspects of the relationships and responsibility of the respective QA organizations. The STP QA organizations coordinate with project management for day-to-day project direction, but report independent of project management for quality-related functions. The HL&P Project QA Manager reports to HL&P's Executive Vice President, Nuclear Group; the Bechtel Project

- QA Manager reports to the Bechtel Los Angeles Power Division QA Manager for Domestic Projects; and the Ebasco Quality Program Site Manager reports to the Ebasco Chief Quality Engineer.

, HL&P has QA responsibility for design, engineering, procurement, fabrica-tion, construction and operation of STP. As described in the QAPD, there is an HL&P perfomance overview of the QA activities of Bechtel and Ebasco, and a Bechtel performance overview of the Ebasco QA activities.

III. Design Review and Design Verification HL&P, as Applicant, has the responsibility for the design of STP. HL&P has contracted with Westinghouse for the Nuclear Steam Supply System which includes the appropriate design review and design verification as related to the W scope of supply. HL&P has contracted with Bechtel to perfom the design for the balance of plant systems and all structures. The requirements of 10CFR50, Appendix B Criterion III, Regulatory Guide 1.64 (Rev. 2) and ANSI N45.2.11-74 have been adopted for project design activities and are applied to Bechtel Engineering work in accordance with Bechtel's Quality Assurance Program documented in BQ-TOP-1, Rev. 3A (approved by the NRC) and the STP Quality Assurance Program Description, Rev. 3.

Bechtel will perfom and document design reviews and design verifications in accordance with its Engineering Department Procedures as implemented for the South Texas Project.

HL&P Engineering perfoms reviews of selected elements of the completed design, design documents and specifications to ensure that contractural requirements are met.

Figure 6 shows the key aspects of the relationship and responsibilities of the Bechtel and HL&P Engineering teams. The interface between HL&P and Bechtel Engineering is through the HL&P Manager, Engineering and the Bechtel Project Engineering Manager. At other Engineering levels there is a regular and routine comunication.

In addition to the HL&P Project Engineering perfomance overview of Bechtel separate reviews of certain elements of the plant design will be per-fomed by the recently created Engineering Assurance Department (EAD). These reviews will provide further confidence in the technical adequacy of the engi-neering and design of the STP.

The Engineering Assurance Department is a separate organization from the STP.

Therefore, Figures 2 and 6 do not reflect this organization. The Manager of the Engineering Assurance Department reports directly to the Vice President, Nuclear Engineering and Construction.

Ebasco, as Constructor, will implement the design issued to it by l

Bechtel.

The design documents will be forwarded to Ebasco through Bechtel Construction Management. As presently organized, all major design will be done by Bechtel.

Any required site design activities will either be perfomed by Bechtel Engineering or will be perfomed under the design control of Bechtel Engineering.
