Innovative Double-Wall Bayonet Tubes HX for DHR System in LFR

Conclusions: ⇨ Integral Circulation Experiments are carried out to reproduce the thermal hydraulic behaviour of a HLM pool-type nuclear reactor primary flow path. ⇨ The test section has been designed coupling an high performance heat source with a prototypical heat exchanger (ELSYW-DHR prototype). ⇨ Steady state full power tests have been run, allowing to obtain first results. ⇨ The results carried out allowed to verify the performance of the W-DHR proposed for ELSY. It allow to achieve the goals defined. ⇨ Several tests have been planned (2012) to complete the characterization of the W-DHR component under transient condition (start-up, shut down). The ICE test section has been properly up-graded for this aim (and not only). ⇨ Integral Circulation Experiments will contribute to the demonstration of the HLM pool-type nuclear reactor feasibility (pool-thermal hydraulic assessment, technological feasibility)
