摘要 |
PROBLEM TO BE SOLVED: To evaluate in a short time a nuclear constant of a fuel assembly having an optional shape and an optional size. SOLUTION: A method of calculating particle transportation has a step (S3) of generating a low-discrepancy sequence, a step (S4) of designating the start point and the direction of ray tracing by the sequence, a step (S5) of ray tracing by using the start point and the direction and determining the locus of a particle, a step (S6) of generating a Green function of a transportation equation of the particle, and a step (S7) of solving a particle transportation Boltzmann equation by using the Green function and evaluating a particle distribution. The nuclear constant is generated from the particle distribution acquired thereby. COPYRIGHT: (C)2007,JPO&INPIT
