Abstract:
The Monte Carlo MVP code system was adopted for the Reaktor TRIGA PUSAPTI (RTP) core calculation. MVP was developed by a group of researcher of Japan Atomic Energy Agency (JAEA) first in 1994. MVP is a general multi-purpose Monte Carlo code for neutron and photon transport calculation and able to estimate an accurate simulation problems. The MVP Monte Carlo code calculation is based on the continuous energy method. This code is capable of adopting an accurate physics model, geometry description and variance
reduction technique faster than conventional method. With compared to the conventional scalar method, this code could achieve higher computational speed by several factor on the vector super-computer[1]. In this calculation, RTP core was modeled as close as possible to the real core and results of keff, flux, fission densities and others obtained from MVP were outputted.
