Design and construction planning for the U. K. standard PWR design

Construction of the U.K.'s first pressurized water reactor, Sizewell B, started in June 1987, and the Central Electricity Generating Board (CEGB) plans to build a series of five or six stations that will replicate the Sizewell B design. The main features of the CEGB strategy are described. The construction planning is started at a very early stage of the project. For Sizewell B some of the key elements are as follows: (1) construction methods and sequences developed for the standardized nuclear unit power plant system (SNUPPS) projects and from Bechtel PWR expertise, modified only where necessary to suit the Sizewell B layout, were adopted. (2) A construction group was involved full-time during the design phase. (3) A 1:75 scale construction model of the principal building of the power block was used to confirm the major building sequences, lifting methods, and positioning of construction access openings and routes. (4) System design clearance occurred sufficiently early to ensure that plant delivery, civil interface, and civil construction design satisfy the construction sequences and timing. (5) Overseas activities were closely observed, in particular the plants at Wolf Creek and Callaway, which were constructed using Bechtel-SNUPPS sequences and methods.
