To evaluate the species and quantities of fission products (FPs) released into the cover gas during the fuel pin failure accidents (In-vessel Source Term) in an LMFBR, the computer code TRACER (Transport Phenomena of Radionuclides for Accident Consequence Evaluation of Reactor) Version 2.0 has been developed. TRACER Version 2.0 includes a new model and modified models shown below. (a) Modified model for fuel temperature calculation, (b) Modified model for bubble release and transport, (c)Modified model for mass transfer in bubbles and in cover gas, (d) New model for FP Aerosols deposition into sodium pool, (e) Modified model for FP decay chain Computational models, input data and output data of TRACER Version 2.0 are described in this user's manual.
