Forecast reactivity program for complex loadings

The program is based on neutron-physics calculations by three dimension programs ''BIPR7'' and ''ALBOM''. Reactivity may be present as a sum of different components depending on different operation parameters. Matrix of the components is interpolated with spline for calculation of intermediate significance. Transient processes are calculated by point model depending on a thermal power and time of keeping this power. Control parameters are prepared during input stage and then reactivities are calculated for each parameter. At last, the sum of the reactivities is achieved and the critical concentration of CH3BO3 is calculated. Critical position of one of the control parameters, such as control rods, power and temperature, are to be found for each of the input conditions. The make-up can be carried our for each state and the change of concentration of CH3B03 found for three flow rates. All of the bases have graphical interface to control themselves by the neutron-physic materials. It is possible to switch the bases to each of power blocks of the station. One can output the calculated energetic fields as graphical picture for any time of the cycle. The results of this program application and the related conclusions will be present in this paper. The program is written in object-oriented language TUBO-PASCAL-6.0, and TUBO-VISION. The program requires IBM PC-AT/386 or 286 with DOS-5.0 or Windows, Mouse and 3.5 available memory on a hard disk. Time necessary to install the program is 15-10 minutes. (author). 2 refs, 6 figs
