dc.descriptionWith the advancement of technology in nuclear industry, nuclear power reaches the state-of-the-art levels and drastically reduce risk contributions by system and equipment. However, despite significant improvements in operator conduct inside and outside the control room, the probability of human error has become relatively greater contributor to the risk of nuclear power plants. Therefore, human error analysis has become one of the biggest challenges in PRA of a nuclear power plant. Currently several human reliability analysis methodologies have been developed for specific applications which are very well established for actions taken in the main control room, however, these methods have lack of structure to assess digital control rooms or external event. In this way, NRC and EPRI developed the IDHEAS-ECA methodology as a new HRA method to replace existing and standard HRA methods. In this study, SPAR-H and IDHEAS-ECA was used to recalculate the human error probability for identified human failure events in SGTR initiate event in Angra-2. Therefore, the results showed that IDHEAS-ECA can produce standard HEP results in comparison with consolidate HRA methods for actions taken in the main control room, however, the need for more specific guidelines is identified to reduce the variability in quantifying the probability of human errors due to the complex structure proposed by IDHEAS-ECA.pt_BR
