The paper presents an overview of programmable safety systems' software reliability analysis methods of nuclear reactors. As software is an important component ensuring a successful operation of the whole system, software reliability becomes an issue of increased importance. The paper presents several software reliability assessment methodologies used by famous European research institutes. At the moment, there are no widely accepted methods of assessing software reliability. Quantitative software reliability assessment is an even more controversial issue, however, it is necessary when performing probabilistic safety assessment. The paper presents the Bayesian network as a tool for estimating software failure probability. [ABSTRACT FROM AUTHOR]
