AbstractAbstract
[en] Different computer codes like RELAP, MELCOR, DIN3D are used for analysing of plants' operational and accidental conditions. All these codes are rather conservative and with high uncertainty, which is controlled by special coefficients. The point of this paper is to show the influence of the boron concentration on radioactivity. For this purpose a three dimensional real model of reactor WWER-440 (V230) was developed. The functional correlation between reactivity and Boron concentration is given and analysed. The suggested correlations can be used for approximately estimation of critical reactor state
