Algorithm for method and dose rate calculating program from pipeline main circuit of WWER-1000

Results of the assessment present a procedure of establishing dose rates for an extended cylindrical surface. It is shown that the presence of reliable data on the radionuclide composition allows to create a software package for analysis of dose rate, based on the calculation of kerma-constant light in a single point in space, followed by interpolating the result over the entire area of the entire area of the source. To improve the accuracy of these calculations are applied nuclear data libraries that are based on the international system NUCLElDE-LARA. This method of calculation established in an annex MS Excel.
