摘要： PURPOSE:To lessen the volume of a pressure control chamber and miniaturize a reactor containing vessel by setting concrete members for making a water chamber in the inside along the inner circumference of a pedestal in the inside space of the pedestal. CONSTITUTION:Concrete members 20 for making a water chamber 23 in the inside are set along the inner circumference of a pedestal 4 in the inside space of the pedestal 4. The water chamber 23 is communicated with a pressure control chamber 6 and coolant 5 of the pressure control chamber 6 is filled in the water chamber 23. At this time the coolant filling part of the pressure control chamber 6 is enlarged by the water chamber 23, the whole volume of the control chamber 6 can be lessened and a reactor containing vessel 1 can be miniaturized.

摘要： PURPOSE:To improve measurement precision and reduce operation cost by providing a flow meter at the sample introduction part of a sampling pipe and nearby a gas analyzer. CONSTITUTION:Sample gas in a dry well 12 is sucked by a sampling pump 24 and guided to the sampling pipe 14, and then dehumidified by a cooler 16; almost all of the dehumidified sampling gas SG is guided to return piping 22 through a by-pass pipe 72 and the remainder enters the gas analyzer 20. An H2 concn. and O2 concn. of the SG entering the analyzer 20 are measured by a heat conduction type hydrogen gas detector and a magnetic wind type oxygen detector and the gas is admitted into the piping. The SG in the piping 22 is returned to the dry well 12 through the pump 24. Vapor condensed by the cooler 16, on the other hand, is discharged into a suppression chamber through piping 70. Thus, the H2 concn. and O2 concn. after the analysis 20 are corrected with measured values of a manometer 58, thermometer 60, differential pressure gauge 62, manometer 64, thermometer 66, and differential pressure gauge 68 to detect the H2 concn. and O2 concn. in the dry well 12.

摘要： PURPOSE:To reduce dynamic load upon missing of cooling member by providing a pipe extending to a dry well in a vacuum destruction valve provided on a vent pipe. CONSTITUTION:It is comprised of a valve 1 arranged on the side of a vent pipe 3 and a piping 13 extending from said valve 1 through the vent pipe 3 to a dry well 5. Upon completion of cooling member missing fault, a container spray will function to drop the pressure in the dry well abruptly thus to open the valve 1 and to prevent the dry well from going to negative pressure by returning the air in wet well gas phase section 6 through the pipe 13 into the dry well 5. Upon fault of cooling member missing, to produce vapor condensing vibration, differential pressure in opening direction is never produced between the dry well 5 and wet well gas phase section 6 thereby it causes no abrupt opening.
