In the nuclear plants, it is required to detect an anomaly as early as possible and to inhibit adverse consequences. This requirement is especially important for the prototype Fast Breeder Reactor "Monju". Therefore, the monitoring and diagnosis system is required to be developed for "Monju" plant equipments. In these days, such a monitoring and diagnosis system can be realized using web technology with rationalized system resources due to remarkable progress of computer network technology. Then, we developed a platform based on web technology for the monitoring and diagnosis system of "Monju". Distributed architecture, standardization and highly flexible system structure have been taken account of in development. This newly developed platform and the prototype monitoring and diagnosis system have been validated. The system on the platform acquires "Monju" plant data and displays the data on client computers using "Monju" intranet with acceptable delay times.

The ultrasonic thermometer is installed on the piping of the secondary cooling system in Monju. The characteristic of the ultrasonic thermometer in case of the sodium temperature change was evaluated as the first stage of system startup test of Monju. The evaluated temperature by the ultrasonic thermometer agreed well with the thermocouple measurement in this condition.
