The main objective of the proposed post Doc research is to investigate the effect of temperature, oxygen concentration and presence of impurities on the pressure loss and heat transfer in a heat exchanger experiment that is currently under design at SCK-CEN.
A real-scale single pin of the MYRRHA heat exchanger will be inserted in the existing COMPLOT facility and coupled to the newly-designed HEXACOM water/steam loop to provide temperature conditions that are identical of MYRRHA. At the same time, the COMPLOT facility will be upgraded with an oxygen condition system.
Experiments will be performed in different conditions representative of the nominal and accidental operation of MYRRHA and pressure loss and heat transfer will measured experimentally.
The researcher will also be asked to evaluate the possibility of other existing facilities at SCK-CEN to perform similar studies on other components and to identify the necessary modifications. Moreover, the researcher should evaluate the relevance of existing experimental data from literature for the MYRRHA case.
