[en] After a long delay in the start of construction of the pressurized water reactor at Sizewell B due to the protracted public enquiry, work is now proceeding to schedule with construction well advanced in many areas. (author)

[en] An outline of the events leading up to the Sizewell B Public Inquiry is given. The terms of reference of the Inquiry, as identified by the Secretary of State, are detailed. The issues involved, including safety, 'need and economics', environmental factors, are discussed. The process of presenting evidence to the Inquiry is described and a general overview of the Inquiry is presented. (author)

[en] A further cost increase for the UK's Sizewell B pressurised water reactor (PWR), now under construction, has been confirmed by leaked documents from the organisation at the heart of the matter, Nuclear Electric (NE). This is the state-held nuclear power company formed from the CEGB. The document presents the results of a study which NE undertook at the request of the energy department, to assess the cost of Sizewell B as a one-off project rather than the first in a ''small family'' of PWRs. The CEGB had planned a family of four or five PWRs, before privatisation came over the horizon. The additional cost, given that Sizewell must bear all the costs which would have been spread over the ''family'', comes in at just over Pound 350m. The final outturn cost of the project, that is prices actually paid rather than adjusted to 1987 money values, comes to Pound 2.621bn. (author)

[en] After the first fuel cycle of the Sizewell B plant, which encompassed 270 days of uninterrupted power generation, refueling was completed in 54 days and 17 hours, which is the third best result achieved at a four-loop power plant supplied by Westinghouse. The whole refueling sequence and circumstances are described in detail

[en] In achieving the extremely low dose targets that have been set for the Sizewell B reactor in the UK, the plant's designers have been extremely fortunate in that they have been able to draw on a vast body of international experience. They have reduced the levels of cobalt in components and materials, made extensive provision for robotics, and tied in formal ALARP (As Low As Reasonably Practical) review procedures to the design process.

[en] The 1258 MWe four loop Sizewell B PWR was seen as the main prize when the British government privatised the bulk of the country's nuclear capacity earlier this year. So far, plant performance has backed this up - following a first operating cycle which ended with a 270 day uninterrupted period of power generation, the refuelling outage was completed in 54 days 17 hours, the third best first outage for a Westinghouse 4-loop plant.

[en] The cost of building Sizewell B, the UK's first PWR is now 32 per cent higher than the original estimate. The Government and Nuclear Electric however, are determined that the project should be completed. The economic arguments for Sizewell B are marginal, but the government wants to establish the PWR option in the UK and has used concern for the environment and the need to maintain diversity to tip the balance in favour of continuing with construction.

[en] In September 1987 Rolls-Royce and Associates was awarded a contract to supply in-service ultrasonic inspection equipment and services for the reactor pressure vessel at Sizewell B in the UK. The contract is now well into the equipment testing phase. The inspection system is described briefly and the scope of the contract is outlined. (author)

[en] The project scope and the organizational arrangements for its execution are defined. An outline of the structure of the Quality Assurance documentation used within the Project Group and at the Group's interface with its contractors are also included. The Project Group's graded approach to Quality Assurance is discussed with details of the four levels of Quality Assurance controls applied. The application of the levels is then discussed by reference to International Quality System standards and the degree of supervision of suppliers imposed by the Project Group, both in terms of QA-related activities and engineering approval of design and other documentation produced by suppliers. The logic of the approach is also followed through into the production and retention of records required to demonstrate compliance to the PPG, and, via the PPG, to the Regulatory bodies. (author)
