Radiation Dose Rate Mapping of Molten Active Fluoride Salt Loop at UED, BARC
Molten salt breeder reactor test facility is being designed and developed at BARC, with main objective of utilizing thorium abundance in India. Experimental facility, namely molten active fluoride salt loop (MAFL), is proposed to be set up in UED, BARC, to study the thermal-hydraulic behaviour of fuel salt as well as blanket salt and their compatibility with different structural materials. Radiation shielding requirements for this facility have been carried out using point-kernel code, QAD-CG. A validation exercise with the same active salt is carried out by measuring the dose at different detector location. The results show that no shielding is required for the dose criterion of 10 µSv/h. In validation exercise, the observed value is matching well with calculated value after a short distance from the source.
