Title: Valve for switching flow velocity
Inventor: YOSHIDA KENGO
IPC: G01F1/32
Filed: 1994-10-11
Abstract: PURPOSE: To obtain a sufficient response from a flow rate sensor even with a minute flow rate by closing a tube by a disc-like valve having a small hole of approximately the same diameter as that of the tube when the amount of liquid is decreased, and converging the amount of liquid at the small hole. CONSTITUTION: A disc-like valve 2 inside a drainage tube 1 having nearly the same diameter as that of the drainage tube 1 is rotated by an actuator thereby to open/close the tube. At the normal flow rate, the valve 2 is opened in parallel to a flowing direction. When the flow rate decreases, tone valve 2 is rotated to be orthogonal to the flowing direction and closed. At least one or more small holes 4 opened at the surface of the valve 2 converge the flow rate to increase the flow velocity. The flow rate with the increased flow velocity is measured by a sensor 5 of a flowmeter at a rear position of the valve 2. A plurality of holes 4 may be arranged radially thereby to distribute the flow rate, whereby the sectional flow velocity is averaged, which improves the measuring accuracy. Particularly, if the diameter of the holes 4 in the periphery of the valve 2 is made larger than that of the holes at the central part of the valve 2, the flow velocity is increased and averaged more efficiently. Accordingly, a sufficient response is obtained from the sensor 5 even when the flow rate is very small.

Title: Method and device for making waste body after melting and volume reduction treatment of low-level radioactive waste
Inventor: AKAGAWA YOSHIHIRO
IPC: G21F9/30
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To improve the filing-up rate in a drum and the waste volume reduction rate and prevent radioactive substances from being scattered and diffusing by making waste bodies through the natural cooling and solidification of discharged melts in an acceptor held by a holding container. SOLUTION: A melt 80' is discharged from a hot water outlet 29 and is loaded into an acceptor 36 held by a holding container 37. Since the atmosphere in a reactor body 21 and a filling-up room 35 is decompressed by the induction of exhaust gas, radioactive gas never leak outside. Air bubbles in dissolved gas and the melt 80' are released through natural cooling, and, at the same time, the melt 80' is separated into a metal layer and a slag layer by the difference in specific gravity. After the solidification, the melt 80' in the acceptor 36 is cooled in a cooling hood 43. Subsequently, a solidified waste 83 integrated with the acceptor 36 separated from the container 37 is put into a drum 45, which is filled with a fixative 84 and is fixedly fitted with a lid 86. In this way, the waste together with the acceptor 36 is housed in the drum 45 to make a waste body 85.  Consequently the size and form of the waste is approximate to the inside form of the drum 45, increasing the filling-up rate of the waste in the drum 45 and improving the volume reduction rate of it.
