Abstract:
In order to solve the calculation problems for the plate-type fuel assembly few group parameter, the establishment of geometry configuration, the calculation of resonance of the fuel plate and the neutron transportation, and the whole calculation process are studied, and the calculation code PICM for the plate-type fuel assembly is established. IAEA benchmark problems are adopted to verify the PICM. The results indicated that PICM can accurately calculate the few group parameter for the plate-type fuel assembly.
