Risk Management for Continued Safety Improvements at Shika Nuclear Power Station

Promotion of Risk Management is Included in Our Quality Policy for Improved Nuclear Safety

 Based on the Safety Regulations for Nuclear Facilities, our president has established our Quality Policy for Improved Nuclear Safety. To achieve our aim of having our employees perform their duties with consistent awareness of the existence of risks, the Quality Policy explicitly states ways to strengthen risk management, such as "Understand safety risks and always try to reduce them."

Development of a Structure Based on the Quality Management System

 In order to identify risks and continuously discuss and implement measures for improvements, we set up a risk management council in April of 2015, and established a risk management system.

Study of Measures for Improved Safety Using Probabilistic Risk Assessment (PRA) *

 In order to continuously study and implement effective measures, we proactively use PRA, as well as training employees to work on PRA.

* Reports and instructions are performed based on the management review (review by the president) in the quality management system.


Probabilistic risk assessment (PRA):
 A method of indicating the degree of safety, with regard to all possible accidents that can occur in nuclear power plants or other facilities, by degree of risk, which is determined through quantitative evaluation of the probability of occurrence of a given accident, and the significance of the potential damage caused by the accident.
