A graphic version of the program Progress++ for calculation and optimization of city electric supply lines has been put into operation. The program works at IBM PC under Windows environment. At present, it is exploited at all the 35 electric power supply enterprises of the Moscow Region as well as at some plants of other regions of Russia. The program is an effective tool for power loss analysis. Following the directions of the program allows one to minimize energy loss from 8-10 % down to 5-8 %. The program can create and screen schemes of various complexity. It also can determine the network graph connectivity index and detect cycles in the scheme. The solving of the system of N Kirchhoff equations is performed during the time of the order N of operations. A certificate has been received from the Ministry of Energy, registration No. 001.
A number of investigations in cooperation with the International Salvay Institute of Physics and Chemistry (Brussels, Belgium) in the field of applied research were performed in 2001:
The cooperation of LIT with the Institute of Radiation Physics and Chemistry Problems (IRP&CP), National Academy of Sciences of Belarus, Minsk, was active. It covers the research field on computer simulation and calculations within the project on sub-critical assembly with MOX fuel for research in nuclear waste transmutation. One of the latest joint published paper  deals with a theoretical investigation of transmutation rates for a number of long-lived fission products and minor actinides as well as with the neutron spectra formed in the sub-critical assembly driven with the following monodirectional beams: (i) 660 meV protons; (ii) 14 MeV neutrons. The main objective is the comparison of neutron spectrum in the MOX assembly for different external driving sources.
