Sizewell B Safety Review

When it came time for a safety review for the Sizewell B nuclear power station, we were there to help. Our team undertook technical authoring and verification of the Periodic Safety Review 3 (PSR3) - Safety Factor 14 assessment, considering the radiological impacts on the environment as a result of station operations. Our work included the review of 10 years worth of operational and performance history for the power station to support the case for continued operation. The report underwent an independent nuclear assessment and was reviewed in line with international guidance.

Following direct receipt of a request for service, recognising the credibility that we have in this discipline, EDF Energy us to undertake a detailed assessment and prepare the corresponding report. An assessment was carried out at the site, split into six arguments covering areas including the environmental monitoring programme, plant systems, radioactive gaseous and aqueous discharges, and radioactive waste arisings. Working closely with site-based personnel, which included a site visit and plant walk-down, evidence regarding the station¡¯s performance over the last 10 years was compiled to support the case for continued operation and operations over the subsequent 10 years.

Our report formed a key part of the PSR3 deliverable, which goes to the United Kingdom¡¯s nuclear safety regulator as evidence that continued operation of these nuclear power stations is safe and that the highest possible standards of environmental protection are being applied, achieved, and sustained¡ªultimately supporting the case for continued operation over the next decade.
