Some problems encountered in the instillation of core and associated components for the Hartlepool and Heysham AGRs

The paper contains a brief outline of the design emphasising those items that were not detailed in previous papers. The items covered include the core, core support and restraint structure, the 'in-vessel' parts of secondary shut down and tertiary shutdown systems, and fuel plug units. There has been a continuous development of engineering and quality requirements for these items since the initial tender for Hartlepool in 1968. The method of incorporating these requirements in both manufacturing works and at site are described. The present method of controlling the quality and documentation through these stages will be presented. (author)
