It has been discovered that communication errors are reasons for many incidents and accidents in various industries including the nuclear industry. As a communication error has been given a considerable attention in analyzing accidents in NPP, there have been numerous studies attempted to explore on communication errors. These works illuminate the communication process, and many cases are simply focused on the statistical analysis of the failure on the information transfer process and the patterns of the communication rather than influential human factors which need to avoid the communication errors. In order to prevent communication errors, an analysis method to find the causes for the communication errors is necessary. Therefore, the analysis method for speaking which is considered important in the conventional works. The qualitative analysis method performs a retrospective and predictive analysis. Through the retrospective analysis, it is possible to fine the root causes when the event is known. And through the predictive analysis, it is possible to find the expected event when the cause is given. In order to complete this methodology, context conditions (CCs), error modes, antecedent-consequent links, and relation between error modes and antecedents are defined. The quantitative method evaluates the probability of the predicted errors in the cognitive speaking process (CSP). In order to complete this method, the CSP and other essential specifications of the methodology are defined. These methods are useful for analyzing communication errors systematically so that we may avoid the communication errors and related events. This work is also useful for the basis for research such as developing the communication support procedure and the communication support tools for cooperation in NPPs.
