| Abstract: | NPDMC is a three dimensional Monte Calor code for multigroup neutron and photon coupled transPOrt duct calculation. NPDMC code brings 87 group neutron and 25 group photon data base made up by ourselves. In the program design, some particular method and the techniques were used so that the "deep transmission" and "small probability" problems which are come across when the Monte Calor method is used in radiation shield calculation are solved successfully. This program can calculate the following: flux,energy spectral,dose ration of neutron and flux, dose ration of photon in pipe, beam hole,gap for research reactor and nuclear power reactor shielding design and analysis. |
