Project summary

Up to now the application of Monte-Carlo codes in the routine design calculations was limited because of large amount of computing time required, even on the most powerful serial computers, to follow the large number of particles, necessary to obtain acceptable statistical uncertainness on the computed averages. Practically, such programs are used as the base of mathematical experiment.

The modern described in literature attempts of Monte-Carlo codes realization on comparatively cheap parallel computers (such as transputers, BBN TC 2000 and so on) demonstrate that Monte-Carlo code speed can be increased nearly linearly with the number of processors. These results open a new possibility of developing time dependent hybrid Monte-Carlo and deterministic code package for reactor lifetime calculations with the acceptable CPU requirements. Our suggest is to base this project on our Monte-Carlo code MCS, elaborated for special transport reactors, which are converted now in accordance with INIS objectives.

Realization of this project will help to redirect the group of specialists - physicists and mathematicians, whose business was connected with being converted field of transport reactors, to creation of universal program of use suitable' for investigation of quasi stationary reactor processes.
