Summary:A method, based on AI techniques, has been developed for detecting and removing interferences among maintenance tasks in nuclear power plants. This method helps plant operators by adjusting the time schedule of the various tasks so that incorrect ordering or timing of plant manipulations does not cause undesirable results, such as a plant trip. This method consists of three main parts. (1) Checking for interference among tasks and plant conditions by analyzing effects of manipulating one component on other components. (2) Searching for a method to remove interference by isolating the problem component from the others. (3) Adding new operations and readjusting the time schedule by the branch and bound method. The performance of this method was checked by off-line simulation test. The result showed that the method can examine and remove the interferences among maintenance tasks.
