The former WPFC Expert Group on Heavy Liquid Metal (EGHLM) Technology was active for several years. Its main objective was to issue a handbook with a collection of theoretical approaches and experimental data in order to deliver recommendations relevant for the design of HLM nuclear systems. After the second version of the handbook was issued, the expert group had re-discussed its scope and future related activities. In particular, as suggested by the Working Party on Scientific Issues of the Fuel Cycle (WPFC), it had been decided to include liquid sodium (Na) activities in the future work plan of the expert group. Secondly, the expert group aims to take the next step 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. After the discussion, the expert group proposed to formulate its objectives as follows below.
Under the guidance of the Working Party on Scientific Issues of the Fuel Cycle (WPFC), the Expert Group on Liquid Metal Technology (EGLM) undertakes activities, with the goal to translate fundamental scientific understanding to application in support of (1) the development of construction codes used for design (design rules); (2) key technical issues for licensing; and (3) recommendations for operation, inspection and handling.
The topical areas and objectives of the expert group are:
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.
