Events initiated by common-cause-failure (CCF) can significantly affect the availability and reliability of nuclear power plant safety systems. In recognition of this, CCF data are systematically collected and analysed in the International Common-Cau

This paper presents a method to study human reliability in decision situations related to nuclear power plant disturbances. Decisions often play a significant role in handling of emergency situations. The method may be applied to probabilistic safety

The reliability of human operators in process control is sensitive to the context. In many contemporary human reliability analysis (HRA) methods, this is not sufficiently taken into account. The aim of this article is that integration between probabi

Probabilistic Safety Analysis (PSA) is a useful and widely utilized tool in the priorization of safety improvements. However, carrying out a PSA is not quite straightforward because of a number of uncertainties related to analysed systems and used me

The modelling of operator errors has been discussed in several contexts and also in various benchmark studies. The estimates of operator error probabilities have differed from each other several orders of magnitude depending on the modelling approach
