J-Power, which is working on the construction of the Ohma Nuclear Power Plant, is trying to improve the safety of the facilities and operation of the plant voluntarily and continuously by using the information resulted from the Probabilistic Risk Assessment (PRA). PRA is based on a method to identify the cause of occurrence, and quantify frequency and impact (risk) of various accident scenarios that can occur in a power plant. Using the risk information resulted from PRA, we can identify the risk factors in...

Construction work of Ohma NPP was suspended because of the Great East Japan Earthquake of March 2011. At that time, progress rate of construction was 37.6%. Construction work was resumed in October 2012. Since, however, the institution of new regulations (new regulatory standards), which could require equipment modifications, was under discussion, construction efforts were made within the limited scope that would not be affected by new regulations As a result, the construction work involving the Reactor Bui...

The Ohma Nuclear Power Station, currently under construction, is an ABWR, and is designed to be capable of using MOX fuel in the entire core. Construction commenced in May 2008 and progress has been made, but the overall progress rate of the construction after the Great East Japan Earthquake has been 37.6%. The operation training simulator was installed ahead of other facilities to implement design change information under the new regulatory requirements, and the simulator is being used to conduct training ...

J-Power, which is working on constructing Ohma Nuclear Power Plant, considering the various kinds of autonomous safety improvement methods. As one of this method, we implemented CAP (Corrective Action Program) at Ohma Nuclear Power Plant constructing site and Head office in 2017.Our CAP system aggregates various awareness items in work and manage the status of corrective actions. In this paper, we will introduce the implementation status and the future improvement direction (implementation of trend monitori...
