KNOO is a four-year initiative set-up to address the challenges related to increasing the safety, reliability and sustainability of nuclear power. Through collaboration between the key industrial and governmental stakeholders and international partners, KNOO has been established to maintain and develop skills relevant to nuclear power generation. Funded through the “Towards a Sustainable Energy Economy Programme” of Research Councils UK, it represents the single largest commitment to fission reactor research in the United Kingdom for more than thirty years.
