Description du projet
Nouvelles procédures d’homologation des technologies nucléaires
Le cadre juridique et les procédures relatives à l’énergie nucléaire ne sont pas flexibles et limitent l’introduction de nouvelles technologies dans les centrales nucléaires en service ainsi que la construction de centrales innovantes à fission et à fusion. Il est donc nécessaire de concevoir de nouvelles approches en matière d’homologation. Le projet HARMONISE, financé par l’UE, élaborera une approche complète visant à acquérir les connaissances nécessaires à l’harmonisation et à la normalisation des méthodologies, des codes et des normes et à l’évaluation des composants des réacteurs nucléaires, tout en tenant compte de la participation des parties prenantes. Le projet se penchera sur les questions liées à la qualification, à la normalisation, à la vérification et à la validation, ainsi qu’à l’homologation des centrales à fission et à fusion, et passera en revue les avantages de l’adoption des jumeaux numériques au cours de la phase de conception. Le projet communiquera ses résultats aux régulateurs de la sûreté nucléaire des États membres de l’UE et de l’Ukraine.
Objectif
HARMONISE puts forward a holistic approach for studying the body of knowledge required to accomplish harmonization and standardization of methodologies, codes and standards as well as the assessment of nuclear reactor components. Departure from a prescriptive-based to a performance-based approach in nuclear regulatory regimes is to be examined under the prism of conformity with the safety objectives of innovative fission and fusion facilities. To this end, data related to fusion installations is expected to stem from the ITER safety demonstrations, whereas data pertinent to advanced fission designs – such as fast breeder reactors and SMRs – will be extracted from relevant EC-funded projects. The basis for HARMONISE activities will be the outcomes of relevant research and cooperation activities in standardization and nuclear safety considering also the lessons learnt from the stress tests performed in the EU. HARMONISE will examine issues related to qualification, standardization, V&V and licensing of fission and fusion installations, while taking into account stakeholder involvement.
The benefits of adopting digital twins of nuclear installations during the design phase will be reviewed, while also identifying the cross-cutting activities that contribute to collaborative research efforts between fission and fusion. HARMONISE will address issues related to the preliminary safety assessments and licensing needs of innovative fission and fusion installations; risk-informed, performance-based approaches in licensing reviews and regulatory decision-making; harmonisation and standardisation on component assessments, methodologies, codes and standards and draw lessons from earlier experience in harmonisation efforts.
HARMONISE findings will be disseminated to the nuclear safety regulators of EU MSs along with the State Nuclear Regulatory Inspectorate of Ukraine as material to be considered during safety verification and licensing of future fission and fusion installations.
