Development of Reactor Accident Diagnostic System DISKET Using Knowledge Engineering Technique

Authors tried to construct multimedia base support system of the manufacturing process with use of the knowledge base and the inference engine on the www server. This knowledge database systematized the knowledge which was obtained from the document and the skilled engineer as much as possible by using a knowledge engineering technique. However, it is difficult for beginner to find the best processing condition under the condition of the material, the machine and the tool on grinding operation by using the conventional database. Especially, when they encountered the manufacturing condition which is not built into the conventional data base, the past optimum conditions cannot be obtained from the expert system. The best method of obtaining the optimum conditions as the solution of this problem is to execute some experiments for this new case. This research proposed the system, which presented a minimum combination of the multi factor experiments for the best manufacturing condition search by using the Taguchi method. We were able to obtain the best condition to use the proposed robust engineering by only 18 times.

Engineering Technique

This experiment, conducted at the OECD Halden Reactor Project, Halden, Norway in the spring 1991, aimed to assess the effect on nuclear power plant operators diagnostic behaviour when using a rule based diagnostic expert system. The rule based expert system used in the experiment is called DISKET (Diagnosis System Using Knowledge Engineering Technique) and was originally developed by the Japan Atomic Energy Research Institute (JAERI). The experiment was performed in the Halden man-machine laboratory using a full scope pressurized water reactor simulator. Operator performance in terms of quality of diagnosis is improved by the use of DISKET. The use of the DISKET system also influences operators problem solving behaviour. The main difference between the two experimental conditions can be characterised as while the DISKET users during the diagnosis process are following a strategy which is direct and narrowed, the non-DISKET users are using a much broader and less focused search when trying to diagnose a disturbance.

Individual Particles

The elemental composition of individual particles is commonly measured by using energydispersive spectroscopic microanalysis (EDS) of samples excited with electron beam irradiation. Similarly, several investigators have characterized particles by using external monochromatic X-irradiation rather than electrons. However, there is little available information describing measurements of particulate characteristic X rays produced not from external sources of radiation, but rather from internal radiation contained within the particle itself. Here, we describe the low-energy (< 20 KeV) characteristic X-ray spectra produced by internal radiation self-excitation of two general types of particulate samples; individual radioactive particles produced during the Chernobyl nuclear reactor accident and radioactive fused aluminosilicate particles (FAP). In addition, we compare these spectra with those generated by conventional EDS.Approximately thirty radioactive particle samples from the Chernobyl accident were on a sample of wood that was near the reactor when the accident occurred. Individual particles still on the wood were microdissected from the bulk matrix after bulk autoradiography.
