The former Expert Group on Heavy Liquid Metal Technology (EGLMH) was active for several years with the main objective to issue a handbook with a collection of theoretical approaches and experimental data to deliver relevant recommendations for the design of HLM nuclear systems. After the publication of the second version of the handbook, it was decided to expand the scope and objectives of the expert group to i) include liquid sodium (Na) activities, and ii) go further in the assessment of available data to bring it closer to application in design, construction and licensing issues on the one hand, and operation, in-service inspection, handling and maintenance on the other hand. As a consequence, the name of the expert group was changed to Expert Group on Reactor Coolants/Components Technology (EGCoCoT). The new denomination indicates that not only the properties of the coolants themselves are covered but also the effects that a particular coolant has on reactor parts such as, but not limited to, structural materials, chemistry control, thermal hydraulics, component behaviour, safety issues etc.
Under the guidance of the Working Party on Scientific Issues of Advanced Fuel Cycles (WPFC), the Expert Group on Reactor Coolants and Components Technology (EGCoCoT) undertakes activities to collect, evaluate and preserve relevant scientific data and "translate" fundamental scientific understanding into application in support of the following areas:
The topical areas and objectives of the expert group:
Environmental conditions and factors that affect materials' behaviour relevant to the structural integrity of confinement barriers and components
Coolant and cover gas issues
Thermal-hydraulics for liquid metals
The EGCoCoT protected area is now hosted on MyNEA SharePoint

The Working Party on Scientific Issues of Advanced Fuel Cycles (WPFC) studies advanced nuclear fuel cycles, including fuel cycle scenarios, innovative fuels and materials, separation chemistry, waste disposal and coolant technologies.
The expert group monitored the feedback from version 0 of the Lead-bismuth eutectic (LBE) handbook, collected, analysed and checked the consistency of expected new results from ongoing heavy liquid metal-related programmes, and updated the handbook and released version 1.
