Abstract

Abstract

In order to provide a more precise and reliable energy source term for the numerical calculation of waste heat export of pulsed reactor, the calculation method XAPRDH and the program with the same name are developed by coupling MCNP program and ORIGEN2 program. In terms of method realization, firstly, the fuel part of each fuel element (including the control rod follower) is divided into 30 independent units in the form of 10 equal parts in the axial direction and 3 parts in the radial direction, forming a total of 3180 units in the whole reactor; Then, the material composition, nuclear reaction cross section, neutron flux density and fission power of each unit are obtained by flexibly calling MCNP program and ORIGEN2 program, and finally the decay heat of each unit is calculated and tracked independently. The analysis shows that the burnup evaluation data in this paper are in good agreement with the literature values, and are consistent with the experimental values within the measurement error range. The decay heat calculation results of the whole reactor are also in line with the industry standards, indicating that the fine calculation method of decay heat established in this paper is feasible and the calculation results are reliable.
