Overview

Gain a deeper understanding of the UK nuclear power plant fleet, design, standards and challenges in substantiating its plant.

The UK nuclear power industry has made use of a large number of different design codes and standards to substantiate its plant. In addition to UK and international standards, the industry has needed to develop specific assessment procedures to adequately meet the enhanced needs of this special industry and the requirements of UK regulators. 

This presentation briefly outlines the history of the UK nuclear fleet, the principle design codes utilised and the development of associated assessment procedures. It explains why these procedures are needed, how they benefit the nuclear industry, and how they can be used in the wider engineering industry and future nuclear designs.
