At the beginning of the presentation, Plant Manager, Junichi Ishihara, of the Hamaoka Nuclear Power station, Chubu Electric Power Co., Inc. greeted all participants saying, "At Hamaoka Electric Power station, safety is our first priority, but being satisfied, or thinking that we have done a good job, is taboo and improving safety even further is important. Today's Caravan is a good opportunity to stop and think about how we dealt with safety in the past and how we are going to deal with it hereafter which will in turn lead to safety improvement in the future.

During the lecture,
*When thinking about safety, it is necessary to know how humans process information. Humans have a single-information processing system and their processing ability largely differs according to consciousness levels. Errors can be minimized if one is tense to a certain extent but that state does not last for long.
*Humans do not set out planning to make an error, and a device that can reduce the occurrence of errors as much as possible by assuming and recognizing that errors are a natural part of human action is ecessary.
*When we look at the structure of consecutive accidents we see that first there is a history of success followed by overconfidence, conceit and pride which plant the seeds of destruction. Then when an accident occurs we think that it's a fluke and not a real problem. When the second accident occurs we think that it was due to a mistake by someone in the field and that everything is still okay and the problem is swept under the rug with passive countermeasures. As this pattern repeats itself and accidents keep occurring, we start to feel that what is happening is not our responsibility and employees lose their sense of motivation which eventually leads to a large disaster. Therefore, the following is important:
1;Throwing away your past honors, overconfidence and pride.
2;Changing failures (negative) into ways to prevent future occurrences (positive).
3;Not passing the buck.
4;Building an environment in which opinions can be openly expressed regardless of position.
5;Making safety a company priority.
