ASME J of Nuclear Rad Sci 1(4), 041013 (Sep 03, 2015) (6 pages) Paper No: NERS-15-1048; doi: 10.1115/1.4030799 History: Received April 09, 2015; Accepted June 08, 2015; Online September 16, 2015

A lead–bismuth eutectic (LBE)-cooled accelerator-driven system (ADS) of 30 MeV and 0.5 mA proton beam has been simulated. The performance of this 15-kW ADS has been analyzed for three coolants (LBE, air, and water), all under variable and constant heat loads using the thermal hydraulic code RELAP5/Mod4.0. Steady-state simulation results for temperature of coolants match the reported design values within 3.2% of relative error. The effect of variation of mass flow rate on power extraction has also been evaluated for the three coolants, namely, LBE, air, and water.
