5. Results of this review
|
| (1) Main Conclusions |
|
• |
In summing up this review of Tomari Nuclear Power Station, Hokkaido Electric Power Co., Inc. we have not found any item in the nuclear safety field that would lead to a serious accident unless immediate remedies were taken. |
|
• |
In conjunction with the implementation of a quality management system at our plant, the plant director has established “Quality Goals” based on the “Quality Policy” formulated by the president and furthermore, each department (room) head has established “Quality Goals” for their own department (room) while also drawing up an “Implementation Plan” aimed at achieving those goals. These plans have received the authorization of the plant director and every single member of each department has familiarized themselves thoroughly with these plans so as to give birth to a uniform plant-wide consciousness in regards to nuclear safety. They are also actively pursuing compliance and each employee has become thoroughly aware of it through education and workshops lead by the head office. They are also putting effort into work safety and the managers are proving that they are taking safety seriously by the formation of employee patrols, manager patrols in which the plant director participates, and safety and health committee patrols. In wake of the Mihama Unit 3 secondary piping rupture accident, as a PWR equal to that of Mihama Unit 3 they are taking this accident very seriously and diligently. |
|
• |
In the future, it is desired that
Hokkaido Electric Power Co., Inc
should increase its own safety efforts toward enhanced safety culture, without accepting things as they are. |
