Embodiment Construction

[0048] The features and advantages of the present invention will be clarified by the detailed description based on the following drawings.

[0049] figure 1 The middle represents the radioactive waste solidification treatment device according to the first embodiment of the present invention. The apparatus of the present invention includes a coagulation drum 120 , a polymer injection device 110 , a measurement device 111 , an internal device 121 for vacuum suction, a vacuum pump 140 , a control device 150 and a recovery container 130 .

[0050] The above coagulation drum 120 contains radioactive waste, but according to needs, an additional shock generating device such as a mechanical vibration generating device, a microwave generating device or an ultrasonic generating device is installed to play an auxiliary role, so that the polymer can fully penetrate into the space between the radioactive waste. Between gaps.

[0051] The polymer injection device 110 mixes and injects pol...

Abstract

The present invention relates to apparatus for the vitrification of radioactive waste comprising a vitrification drum (120) capable of accommodating radioactive waste in powdered, granulated and various others forms; a polymer injection device (110) that injects polymers into said vitrification drum and mixes said polymers with radioactive waste contained therein; a measuring device (111) that measures the amount of polymer injected into said vitrification drum; an internal vacuum suction device (121) inserted into the bottom of said vitrification drum; a vacuum pump (130) connected to said internal vacuum suction device; a control unit (140) that controls said polymer injection device (110) and said vacuum pump (130) based on signals received from said measuring device (111); and a recovery container (150), connected to said internal device, that recovers polymers flowing out from said vitrification drum and enables verification of the polymer permeation status inside the same.

Description

technical field [0001] The invention relates to a radioactive waste coagulation treatment method and device, in particular to injecting polymers and vacuum suction into granular radioactive waste and wastes in the form of small powder particles and various forms that are difficult to penetrate and coagulate. The unique cross control is easy to penetrate the solidified material densely, minimizes the void inside the solidified body and enhances the strength of the solidified body; and prevents unexpected outflow accidents caused by the coagulation work in advance through multiple safety devices, thereby improving the safety during operation and maximize the load capacity of waste, enabling safer and less expensive storage in radioactive waste treatment plants. Background technique [0002] During the operation of a nuclear power plant, radioactive liquid waste that inevitably occurs in large quantities in a radiation management area is usually evaporated by an evaporator, but...
