Applicability of Methods for Human Reliability Analysis for Computerized Procedures in Nuclear Power Plants

This paper analyzed the differences of digital procedure and papery procedure from the perspective of human factor engineering,and put forward the additional performance shape factors the digitized accident procedure need to consider.Several commonly used human reliability analysis（HRA） methods are comparatively analyzed.In addition to A Technique for Human Error Analysis（ATHEANA）,the common HRA method used in the digital procedure has obvious problems.ATHEANA is with a certain flexibility and can be used as an alternative method for HRA analysis based on the digital procedure because it is not divided into specific behavior types and PSFs.The biggest difficulty of HRA analysis is to obtain the basic data.The data acquisition of HRA method considering the behavior characteristics of the operator under the digital procedure should also be the main research direction.
