Plant Safety and Risk Assessment
Technical Area 1
Technical Area 1 is devoted to improving the physical understanding and the numerical modelling of the relevant phenomena involved in Nuclear Power Plants (NPPs) incidents and accidents, to increase the capacity and comprehensiveness of the plant behaviour and to enhance the accuracy of safety margin assessment accordingly.
Technical Area 2
The scope of Technical Area 2 is closely linked to the main public safety goal for nuclear power – to prevent a societal calamity and huge economic loss. With appropriate site risk evaluations, plant designs and management, current Generation II and future Generation III NPPs show high levels of robustness and low probabilities for severe accidents (SA).
Improved Reactor Operation
Technical Area 3
Technical Area 3 is devoted to improving the technical and economical characteristics of reactor operation by various measures and also to minimizing the radiological impacts on the plant workers, the environment and general public during normal reactor operation (covering periods of shutdown, reshuffling, abnormal operational situations and emergency states, but excluding severe accidents).
System and component integrity
Technical Area 4
Structural assessments are an important part of NPP management programs (e.g. ageing management, maintenance & design changes) and are one of the requirements for effective periodic safety reviews. Aspects that need to be considered include definition of integrity assessment over the whole life cycle, the various degradation mechanisms, ageing issues, safety margins and harmonisation issues form the scope of TA4.
Fuel Development, Spent Fuel Management, Waste Management and Decommissioning
Technical Area 5
Technical area 5 covers the development of nuclear fuel for existing, advanced and innovative core designs, aspects of fuel use in reactors and the fuel management steps – manipulation, transport and interim wet and dry storage. It includes factors relating to the generation and management of radioactive waste, and the dismantling and decommissioning of nuclear power plants, as well as safety issues linked with: fuel behaviour in normal operation and accident conditions, and the safety of the fuel cycle, including the investigation of criticality accidents and radioactive material dispersion.
Innovative Large Water Reactor designs & technologies
Technical Area 6
Innovation is the key driver of Technical Area 6 for addressing technologies with the objective of supporting the competitiveness of LWR, including enhanced safety.
Currently operating nuclear power plants and advanced LWR concepts, such as small modular reactors (SMRs), are defining the overall R&D program of TA6. In the same way, LWR integration into the energy mix will raise new potential requirements for the development of innovative technologies .
European Network for Inspection and Qualification
Technical Area 8
The European Network for Inspection and Qualification (ENIQ) is a network dealing with the reliability and effectiveness of non-destructive testing (NDT) for nuclear power plants (NPP). ENIQ is driven by European nuclear utilities and is working mainly in the areas of qualification of NDT systems and risk-informed in-service inspection (RI-ISI).
Technical Area 8 – ENIQ has two sub-areas in which the technical work of the TA is performed, the Sub-area for Qualification (SAQ) and the Sub-area for Risk (SAR).
