dc.description.abstractAs computing power increases, the Monte Carlo method becomes popular in nuclear reactor physics analysis due to its capability of scalable parallelization and handling complex geometry and continuous-energy nuclear data. This paper describes and compares the Monte Carlo method for reactor transient analysis based on two quasi-static methods; 1) the improved quasi-static method and 2) the predictor-corrector quasi-static method. In both methods, a linear approximation of fission source distributions during a macro-time interval is used to provide the analytic solution to delayed neutron source, and fission source iteration is used to solve the transient fixed-source problem. To solve the transient fixed-source problem via Monte Carlo method, the conventional particle-tracking method is modified. In numerical results, the two quasi-static methods in Monte Carlo calculation are compared with the direct time-dependent method of characteristics (MOC) on a TWIGL two-group problem for verification of the computer code. Then, transient analyses via the two quasi-static methods are presented and compared on a continuous-energy problem.-
