The objective of this topic is to perform numerical CFD calculations in order to simulate cold trap loading for LBE systems capable of capturing PbO precipitates. To achieve this, the following steps need to be undertaken:
Calculate the hydraulic charateristics of the current cold trap design
Taking into account external cooling of the cold trap, the temperature profile of the LBE needs to be calculated in function of LBE inlet conditions
Based on the obtained temperature field, the formation of lead oxide and the subsequent retention should be predicted
The effect of cold trap loading on the hydraulic performance should be assessed
The conclusions of this study will directly be implemented as an optimization of the cold trap design used in the LBE loops at SCK•CEN.
