AbstractAbstract
[en] Calculation technique for particle transport in systems which include regular finite lattices with great amount of elements is suggested. Concept of mobile unit is introduced for efficient description of geometry of regions which contain lattices. Using mobile unit and introduction of coordinate system connected with lattice it is possible to formulate unified approach when types considering lattices of different and to realize it in unified universal geometric module. Using the suggested technique it is possible to conduct calculations of complex systems practically without any restrictions for cell number in the system. Calculation example for multiplication factor and neutron lifetime in critical periodical lattice of uranium rods in aqueous medium is given. 5 refs.; 1 fig.; 1 tab
