摘要： PROBLEM TO BE SOLVED: To provide a noncondensable gas exhaust device for a condenser capable of preventing rubbing vibration of a turbine and shortening a vacuum degree adjusting time for the condenser.
SOLUTION: The noncondensable gas exhaust device 20A has a first extraction amount regulating valve 2, a noncondensable gas extractor 3, a noncondensable gas extraction condenser 4 and a recoupler 5 installed at a noncondensable gas extraction pipe 21 from the condenser 1 side. A by-pass pipe 22 smaller in inner diameter than the noncondensable gas extraction pipe 21 is connected to the noncondensable gas extraction pipe 21. A second extraction amount regulating valve 8 installed at the by-pass pipe 22 has a smaller bore than the first extraction amount regulating valve 2. When adjusting the vacuum of the condenser, a controller 10 controls the opening of the second extraction amount regulating valve 8 based on the vacuum measured at a vacuum gauge 9 installed at the condenser 1.

摘要： PROBLEM TO BE SOLVED: To provide a device for controlling a flow rate of feed water that prevents a decrease in the flow rate of feed water when a trip is caused in one of pumps of a feed-water supply system to mitigate the draw-down of a nuclear reactor or the like when using a variable speed motor driven feed-water pump, and to provide a power plant using the same.SOLUTION: The device for controlling a flow rate of feed water includes: a vessel such as a nuclear reactor or a steam generator with a function of controlling a water level in a power plant; a multi-unit pump set including reserve machines in which a plurality of kinds of pumps are coupled with one another in a direction of a flow from the upstream side to the downstream side to increase the pressure of condensate step by step so as to feed the condensate from a condenser to the vessel; and a feed-water flow rate control means for controlling the flow rate of the feed water of a pump coupled in the most downstream position in the multi-unit pump set. The feed-water flow rate control means includes a predicted flow rate increasing circuit that, when detecting a trip caused in at least one driven pump, rapidly increases a flow rate of the other pump which is continued in operation to a preset flow rate immediately after the detection of the trip.

摘要： PROBLEM TO BE SOLVED: To provide a pipe condition monitoring device capable of monitoring conditions of a pipe welded section such as cracks and reduced welding thickness during normal operation of a plant.
SOLUTION: A plurality of IC tags 4 with sensors are arranged on a strip of tape or a sheet 3, and the strip of tape or sheet 3 is circularly mounted along a pipe welded section or an orifice 2. Further, when the tape or sheet 3 is circularly mounted along the pipe welded section or orifice 2, the IC tags are arranged in a plurality of rows so as to be located in front and in the rear of the pipe welded section or orifice 2 against a flowing direction of fluid in the pipe.
