Radioactive waste resin metering system

Abstract

The invention discloses a radioactive waste resin metering system, comprising a waste resin storage tank, a waste resin metering tank, a dehydrating pump, a water metering tank and a waste barrel, wherein the waste resin metering tank is connected with and receives water-containing waste resin from the waste resin storage tank, the dehydrating pump is connected between the waste resin meter tank and the water metering tank, dehydrates stored objects in the waste resin metering tank, and discharges the dehydrated water into the water metering tank, and the waste resin metering tank and the water metering tank are respectively connected to the waste barrel to add the dehydrated waste resin and water into the waste barrel according to the preset ratio of a solidification formula. Compared with the prior art, the radioactive waste resin metering system has the advantages that the problems of difficulty in metering and large metering error of radioactive waste resins of nuclear power plants or other nuclear facilities are solved by the mode of separating the waste resin from the water and then accurately metering the waste resin and the water, and the aims of realizing the precise preparation of the solidification formula and solving the reuse problem of radioactive waste water are achieved simultaneously.

Description

technical field [0001] The invention relates to the field of nuclear power waste disposal, and more specifically, the invention relates to a radioactive waste resin metering system. Background technique [0002] Nuclear power plants or other nuclear facilities mainly use desalting bed technology for water purification treatment. Since most of the water treated by the desalting bed contains radioactivity, the resin in the desalting bed will also contain a large amount of radioactivity after failure. At present, the treatment of radioactive waste resin usually adopts cement solidification process to produce radioactive waste resin into a stable solidified body of radioactive waste for subsequent temporary storage, transportation and disposal. To make the cured body produced by the cement solidification process meet the requirements of the national standard GB14569.3, the key lies in the realization of the waste solidification formula. The components of the solidification formu...

Problems solved by technology

However, since the resin is solid, its interface 140 in the airtight tank 10 is not as flat as the liquid interface, and tends to be in the shape of large waves or small hills, which causes a large error in the measurement of the waste resin 14 by the liquid level gauge 12 In addition, since the saturated density of the resin is about 1070kg / m3, which is equivalent to the density of water, it is difficult for the liquid level gauge 12 to identify the interface between the waste resin 14 and the water 16, which further aggravates the measurement difficulty of the liquid level gauge 12
