Because we came in contact with the water in the direct furnace about the core water level measurement system that we applied TOR to and we could measure water level in succession, we pushed forward our original development separately from a national project. On the other hand, a the thrmocouple-type hydrograph is developed by the national project. It is really desirable to use in combination both from the hydrograph loading number in the core, precision, an aspect of the diversification when it uses it in ...

About an application and the constitution in the true furnace of the core water level measurement system that I applied TDR to

The water level in the nuclear reactor measures it by measuring the differential pressure of a vapor phase part and the liquid phase part in the nuclear reactor. However, the temperature in the storage container becomes the high temperature at the time of the SA such as the Fukushima accident, and the water in the datum level device evaporates, and nuclear reactor water level becomes immeasurable. We developed a technique to measure the water level in the direct furnace by applying TDR (time-domain reflecto...

Development of the Reactor water level measurement system using the TDR technology

It is thought that we can let knowledge of "Human" substitute by building a function to utilize predictive information, and to extract a similar example from these documents in AI. In this way, we can largely reduce a burden on "Human" by building past accidents as a database, and being resemblance or equivalence, and extracting a cormorant from that. But we may list it by expression varying among document creators even if it is the same company. When we performed a document search with disregard to such a ...

Examination of a method to search past similar cases registered in NUCIA from predictive information detected by SIAT

System Invariant Analysis Technology, SIAT can detect abnormal behavior of plant parameters. However, the cause analysis functionality for the abnormal behavior has been strongly desired to support engineers making decisions for taking appropriate actions. For that purpose, we have developed the cause analysis functionality based on the result of the broken invariant analysis. Database of the broken invariant distribution with that cause is prepared and the similarity with the current abnormal behavior of t...

Development of the cause analysis functionality for the abnormal behavior detected by SIAT

A place to depend on an experienced of the knowledge of operation engineer and the maintenance engineer so-called experienced engineer about plant administration is big and, in us, will entrust it to "Human" from a process of the phenomenon identification to the last judgment of the result. Because a human resource is limited, we cannot depend on "Human" for all the judgments. Therefore, about keeping a function to substitute in [Human = experienced person] in AI namely SIAT and other AI system namely IBM W...

Advance of plant monitoring technology by cooperation of an system invariant analysis technology (SIAT) and IBM Watson Explorer

We applied NEC SIAT engine in cooperation with an NEC stock and developed the system which detected the abnormality of the plant early. This system was able to demonstrate that I could detect abnormality early by the inspection of conventional actual machine data. However, I depended on the experienced engineer about the details of the phenomenon, the cause. I applied Watson of IBM this time and developed a technique to study to the details of the phenomenon, a cause by letting you cooperate with an omen sy...

The purpose of implementing the Pre-Fire Plan with PRISM software is to assist firefighters to respond to fires properly and quickly by defining firefighting strategies (Pre-Fire Plan) including access routes for firefighters and location of fire-fighting equipment in advance. Fire could be a complex emergency causing unexpected failures and damages and it is extremely difficult to predict the necessary fire response. PRISM Pre-Fire Plan Software can display the fire-fighting strategy of each area of the pl...

Implementation of electronic pre-fire plan (PRISM) at Shimane Nuclear Power Station

Shimane Nuclear Power Station has established a procedure manual for configuration management in line with the introduction of the Nuclear Regulatory Inspection in April 2020. We have also introduced a new system to carry out operations related to configuration management. This paper describes the Shimane Nuclear Power Station configuration management efforts....
