News & Events-Frazer-Nash study to support nuclear reactor life extension programme

Engineering consultancy Frazer-Nash is providing support to an experiment as part of a project for EDF Energy to support the life extension of the UK's advanced gas-cooled nuclear reactors (AGR) which has long been a strategic priority for EDF Energy.

The study, being undertaken at the Materials Test Reactor in Petten, Holland, will see the engineering experts providing technical support and interpreting materials data for integration into EDF Energy's AGR safety case.

The experiment has been designed to accelerate the rate of material degradation to simulate how the integrity of these materials within an AGR reactor will be affected over a longer period of time.

Frazer-Nash are advising EDF Energy on what samples to put into the test reactor and the types of environments to expose them to. .After accelerated degradation the material samples will then be measured and modelled in order to support plans to prolong the generation of power at the AGR sites across the UK.

This will provide EDF Energy with a greater understanding of the future validity and integrity of the AGR's structural properties,. The company will then recommend how applicable the measurements and revised material models will be to EDF Energy's AGR core reactors and future reactor behaviour.

Mark Joyce, Frazer-Nash Group Leader, commented: "We are delighted to be playing a central role in what is a crucial project. We will be using our extensive nuclear safety, engineering and analysis experience to provide EDF Energy with a coherent assessment of the AGR materials and support the life extension programme."
