The severe accident at TEPCO's Fukushima Daiichi nuclear power station (TF1 accident) in March 2011 brought the lost of the functions of many instrumentation systems. In order to enable the measurements of the important parameters such as reactor water level, temperature and so on even in a case such as the TF1 accident occurs, severe accident instrumentation systems are being developed. In this paper, new system configurations of BWR water level measurement and temperature measurement in primary conta...

In order to optimize plant maintenance, it is important to diagnose an integrity of equipment and use it for maintenance planning. We developed the integrity diagnostic method combining statistical model and physical model. The statistical model detects abnormality from process data and estimates abnormal parameters. The physical model estimates failure equipment from abnormal parameters. As a result of test data evaluation, it was confirmed that the proposed method can detect anomalies and estimate faulure...

For the safety improvement of a nuclear power plant, safety equipments are constructing additionally under new regulatory requirements. With the increase of safety equipments, it is important to maintain and improve reliability of equipments by inspection. To improve reliability of equipments, we developed a diagnostic system for steam turbine. This system consists of statistical model and physical model. Wih the statistical model, it is possible to detect abnormality from plant operation data and estimate ...
