Generally, it has been found that skills, attitudes and human performance are shaped during change and transformation; greatly depending on learning. Learning is a cognitive process leading to observable change in behavior. Considering learning impact, reduction of human error probability is obviously seen in various tasks in hazardous potentially industrial systems. In this paper, using an innovative approach in engineering learning theory in to general tasks of Tehran Research Reactor (TRR), the impact on human error probabilities is discussed utilizing Human Error Assessment and Reduction Technique (HEART) method and Reliability Laboratory (RELAB) code. Probability of occurrence of four probable accidents in reactor without considering human error, by considering human error and contribution learning in various tasks is calculated quantitatively. Benchmarking of the method and the conclusion are done by comparing them with the results of similar reactors.

Keywords: Human Error, Learning engineering, Probability, HEART, RELAB, TRR.
