Responsibility

In accordance with the CEGB QA policy and the adoption of BS5882 by the CEGB as the appropriate basis for the total QA programme for its power stations, it is the responsibility of the CEGB to ensure that a QA programme for each plant is established and implemented. In each phase of a power station’s life, many organisations are involved in providing plant items and services to the CEGB.

Where these organisations lie within the CEGB, their responsibilities are defined within the CEGB Directives, it may be necessary to prepare project — specific QA documentation, for example, in compli­ance with nuclear site licence requirements, in addition to generic procedural documentation.

Where organisations external to the CEGB are sup­pliers, the CEGB will require that each organisation demonstrates that its own QA arrangements are ade­quate and specifies or approves those of its contractors, suppliers and agents. This hierarchical system of iden­tifying detailed responsibility, together with formal CEGB monitoring of the immediate purchaser, is followed throughout the purchaser/supplier arrange­ments whilst not relieving the CEGB of its overall QA responsibility.

Design

Design covers not only how an end item is to be made but also how it is to be used. The designer is responsible not only for the proof of integrity of the design by analysis and testing, and for providing the manufacturer with the instructions of how to make an item, but also for provision to the operator of the item of the instructions for the use of the item.

The objective of QA in design is to provide mea­sures of confidence that the management system re­sponsible for design has adequately considered the requirements for reliability, performance and safety in formulating the design, has provided instructions to the manufacturer for the realisation of the design and has prepared an examination, inspection and test schedule that will confirm the design assumptions.

Procurement

Procurement covers all the activities associated with realising a declared design in an end item, i. e., re­quisition, manufacture and construction, the supplier is responsible for both the design and the procurement of plant systems.

The objective of QA in procurement is to provide measures of confidence in the ability and performance of a supplier in the production of the end item.

The assessment of the quality capabilities of sup­pliers is an essential feature of the procurement pro­cess. The function of the plant item will determine the safety significance and hence the QA actions ap­propriate in the procurement process. This will include the identification of an appropriate quality manage­ment system standard and the particular actions, such as procurement authority approval of QA programmes and quality plans, enforceable through the terms of contract.
