Neutron Detector Management for AGR Nuclear Power Stations

This technical report outlines the neutron detector management program implemented by Curtiss-Wright for EDF Energy's fleet of advanced gas-cooled reactor (AGR) nuclear power stations in the UK. The report details the challenges faced due to the obsolescence of neutron detectors, which are critical for monitoring reactor safety and performance. Following the acquisition of the AGR stations, EDF Energy identified a significant risk of operational shutdown due to a shortage of replacement detectors. The report explains how Curtiss-Wright addressed this issue by regenerating the necessary manufacturing skills, updating detector specifications to modern standards, and establishing a custom manufacturing facility. It also highlights the successful collaboration with the Office for Nuclear Regulation to ensure compliance with safety standards. As a result, EDF Energy secured a reliable supply of neutron detectors, enabling the continued operation of its reactors and protecting an annual revenue of £1.9 billion. The report concludes with the benefits of the partnership and future collaborative projects.
