摘要： PURPOSE:To enable automatic recognition of operating conditions by calculating operation change patterns in three directions on the basis of significant detection signals from a plurality of main plant signals of a nuclear power plant and by comparing these data with a basic operating condition. CONSTITUTION:An operation change detecting element 1 detects significant level changes in main plant signals. An operation change analyzing element 2 determines data on change rates from raw data, as patterned analog signals, compares the change rate data thus obtained with a threshold value for detecting a change in operation, and outputs operation change patterns in three directions as analog time-series informations. An operation state recognizing element 3 executes comparison and collation with an operation state data base on the basis of a change pattern of an output of the analyzing element 2 and outputs the state of operation for a coincidental data base. In each recognition of the operation, comparison is made with the operation state data base 4 and a coincidental operation state information is outputted. A histeresis information recording element 5 records and stores the state of operation, an analog level information and an information on date and time which are obtained in the recognizing element 3, and outputs them to an operation state output device.

摘要： PURPOSE:To detect a leakage in a pressure vessel of high-temperature.high- pressure in an early stage of plant operation by providing a pipeline which sucks the gas of the environment where the leakage occurs and a sensing device which monitors the composition of the sucked gas. CONSTITUTION:A control rod housing and in-core monitor guide pipe 5 are mainly passed through a through hole 4. When areas I, II, and III are set as shown in the figure, the environmental condition of each area is different from that of another during the plant operation and, when a leak occurs at the through hole 4, the core water in a reactor pressure vessel is first vaporized and the vapor fills up between the bottom mirror 3a of the pressure vessel 3 of the area II and a heat insulating material 6. Therefore, when the leaked gas filling up the area II is sucked into a condensing device 8 and stored in a drain reservoir 10 through a drain pipe 9 and a sensor 11 detects the humidity and liquid level of the reservoir 10, the occurrence and extent of a leakage can be discriminated.

摘要： PURPOSE:To improve the efficiency of the diagnosis of a plant by constituting the device in such a way that data are tentatively preserved and, at the same time, the data sampling period is automatically set in accordance with the changing state of the data so that collective recording and retrieval of the data can be managed easily. CONSTITUTION:When minute unforeseen abnormality occurs in analog signals only, the raw data before and after the abnormality are recorded by means of an abrupt change sensor 8. Accordingly, an abrupt change sensing and calculating data sampling period setting processes are stopped while the raw data are recorded so as to prevent occurrence of a malfunction. When an output changing operation by which only analog signals show a relatively fast change occurs, a calculating data sampling period setting device 5 discriminates the output of a changing rate measuring instrument 7 and changes the sampling period and records calculated data. An abrupt change in digital signals is also processed similarly to the abrupt change in analog signals. Therefore, state data obtained from the operations of various parts of a plant can be recorded accurately and, at the same time, retrieval and output after reproduction and edition of data can be carried out quickly. Thus plant diagnosis can be made effectively.

摘要： PURPOSE:To obtain detailed information on the surfaces of equipment, piping, etc., by supplying an ultrasonic wave sensor with a small-wave-number ultrasonic wave which is sent by an oscillation wave controller composed of an astable multivibrator, a monostable multivibrator, a sensor driving part, and a sensor driving high-voltage power source. CONSTITUTION:The oscillation wave controller 4 consists of the astable multivibrator 9, monostable multivibrator 10, sensor driving part 11 and sensor driving high-voltage power source 12. A signal obtained by the multivibrator 10 is shaped into pulses, which are inputted to the sensor driving part 11. Then the pulses shaped by the front stage of the driving part 11 are inputted to a high frequency high-voltage amplifier after the application tie of a reverse voltage is adjusted by varying the time constant CR of a CR circuit. Consequently, an ultrasonic wave with an extremely small wave number is obtained and outputted from a controller 4. Consequently, the arrival time of a reflected wave becomes clear, so unevenness information on the surface of the equipment, etc., is known faithfully.
