Abstract

In order to minimize the radioactive waste volume at the Ukrainian NPP (nuclear power plants) solid waste is burned and compressed and liquid one evaporated. This dramatically increases their activity as well as their radiation doses during of operation process. In accordance with the ALARA principle the technological solutions that reduce doses to personnel were proposed. First part of the complex built on Zaporozhye NPP consists of processing waste incinerators and pressing facilities. The characteristics of the radiation fields for varying geometries of this facility and isotopic composition of obtained waste was simulated using PENELOPE and GEANT codes. Part of the results was performed using the software packages developed by the authors using point sources method. During operations with burned waste pressed ash the wall thickness of buildings, where equipment is placed is needed, up to 40 cm of concrete. Thickness of the steel technological doors for these premises is required to be of about 12 cm. The alternate design of technological doors (» 2cm of steel) by adding special gateway system is to be proposed.
