摘要： PURPOSE:To effectively perform monitoring or maintenance of the soundness of a plant by inputting a pattern of power spectral density (PSD) obtaining a process signal with the use of signal processing technology to perform pattern recognition with the use of a neural net. CONSTITUTION:After data from a plant 1 are collected in a data converting collector 2, diagnosis is performed on whether abnormality occurs in the plant or not with the use of a diagnosis device 3. In this case a PSD pattern of an event X observed in the plant with respect to a learning network in which already known events E1, E2, E3, E4 can be discriminated is input. If the event X is the learned already-known event E2, a neuron of an output layer corresponding to it is excited to identified an abnormal cause immediately. If the event X is an unknown event, the neuron of the output corresponding to it is determined, a learning is performed so that a correct pattern may be given so as to excite the neuron and the importance of the network may be regulated again. If a cause exceeding the event X is confirmed by later analysis, its cause can be identified by storing it.

摘要： PURPOSE:To enable a presumption of a fuel break position from an increasing pattern of a counting rate fluctuation which detects the fuel break by obtaining previously a reaching rate with which fission products discharged from a fuel assembly, dissolve into a coolant and reach a delayed neutron detector (DN meter). CONSTITUTION:A temperature signal from an outlet thermometer 1 of an assembly and an inlet thermometer of an intermediate heat exchanger is converted by an A/D converter 4 after being fed to an analogue filter 3, and then is fed to a digital filter 5. An output of the filter 5 is fed to a calculating part 6 of flow rate and temperature distribution, and a fluctuation power calculating part 7, to calculate the flow rate and temperature distribution, and the fluctuation power, and thereafter distributions of a flow rate fluctuation and a temperature fluctuation power, are obtained by a calculating part 8 of distributions of a flow rate fluctuation and a temperature fluctuation power. Then, from these flow rate fluctuation and temperature fluctuation, distributions of fission products (FP) concentration and a fluctuation power of the FP concentration can be obtained, at a next stage calculating part 9. With this procedure, a fluctuation power of DN counting rate is obtained at a calculating part 10, as a further step and thereafter is fed to a break position judgement table 11 in a next stage.

摘要： PROBLEM TO BE SOLVED: To provide an estimation method for software development/application/maintenance costs for quantitatively evaluating estimation errors of software development/application/maintenance costs and serving cost estimation. SOLUTION: Input parameter values for estimating the scale of software and their probability distribution are inputted. A probability distribution of estimation values on the software scale is calculated according to the inputted input parameter values and their probability distribution, and based on a function point method. From the calculated software scale, man-hours and the number of steps required for its development, application, and maintenance, are estimated as a set of varying numeric values. A probability that the values of the estimated man-hours and number of steps deviate from the tolerance of a budget is evaluated as a risk. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To detect a leakage position and the like with high precision over a wide range by performing a frequency analysis process on a frequency constituent of sound, which is generated when fluid leaks, on the basis of sound data for the sound collected from a monitoring object by means of ultrasonic wave microphones and detecting fluid leakage on the basis of an increase in the frequency constituent above an audible sound area. SOLUTION: By means of a plurality of non-directional ultrasonic wave microphones 1a, 1b,...1n arranged in a monitoring object, through which fluid such as high pressure gas flows, at certain intervals, leakage sound generated in the case of high pressure gas leakage is collected so as to be converted into an analogue electric signal, which is amplified by means of an amplifier 2 and converted into a digital signal by means of an A/D converter 3 so as to be inputted into a computer 4. In this process, only the high frequency constituent of the leakage sound generated in the case of high pressure gas leakage is taken out so as to be given to a leakage detection unit 6 and a leakage angle estimation unit 7. After gas leakage is detected by means of the leakage detection unit 6, a leakage angle and a leakage sound intensity distribution are found by means of the leakage angle estimation unit 7, and these results are displayed on a monitor 8.

摘要： PURPOSE:To support the formation of an inspection process and to shorten working by providing a system with knowledge base having the hierarchical records of information such as inspection items and conditions and an inference engine for forming an optimum inspection process based on information from the knowledge base, an inspection plan and the states of a plant and constitutional apparatuses. CONSTITUTION:Ranges A relating to inspections, sorts B, items C, system equipment D, objects E and inspection detail information F are hierarchically recorded in the knowledge base 1. When a worker 5 selectively inputs a period, a range and an item, the outline of the inspection plane with priority is indicated and the plane is corrected if necessary. Then, the state (disabling of operation of a certain system to repair an apparatus) of the plant 3 is inputted. Thus, the validity/invalidity of execution is decided based on information obtained by conversation with the knowledge base 1 to form the plan. To change the plan, a condition to be changed is inputted to the system, so that an optimum plan is reconstituted. Thus, the inspection work can be shortened.

摘要： PURPOSE:To enhance the safety of a plant and to improve the working ratio by deciding the suitable disposition in accordance with the significance of the abnormality detecting signal of the plant and displaying this decision. CONSTITUTION:When the abnormal signal of a plant 1 is detected by an abnormality supervising device 3, an abnormal time disposing deciding device 4 is started. Next, the device 4 investigates whether or not the signal, in which the abnormality is detected, is the abnormal signal of A rank. When the signal is judged to be the abnormal signal of A rank, immediately the plant safety stop disposition for it is displayed at a displaying device 5. When the signal is judged not to be the abnormal signal of A rank, the abnormality recovering disposition prepared in accordance with the abnormal cause is decided and this is displayed. Thus, the safety of the plant can be enhanced. Since the unnecessary plant stop is avoided, the plant working ratio can be improved.
