Abstract

The invention discloses a storage structure for a dehydrated ion exchange resin of a nuclear power plant. The storage structure comprises a barrel and a top lid which are made of metal lead. A layer of filter screen is flatly laid in the barrel, and the number of meshes of the filter screen is 60 to 80. An electric heating device and a drain hole with a plug are arranged within an area under the filter screen in the barrel. A temperature sensor and a humidity sensor are arranged within an area above the filter screen in the barrel. A display screen is arranged on the outer sidewall of the barrel, and the temperature sensor and the humidity sensor are connected to the display screen. A dehumidifier is arranged on the internal surface of the top lid. A transparent window is also arranged in a sidewall of the barrel. The invention aims at providing a storage structure for a dehydrated ion exchange resin of a nuclear power plant to solve the problem of easy breakage of an ion exchange resin in dehydrated storage in the prior art and achieve the objective of increasing the recovery utilization ratio of the ion exchange resin.

Description

technical field [0001] The invention relates to the field of nuclear power plants, in particular to a storage structure for dehydrated nuclear power plant ion exchange resins. Background technique [0002] Ion exchange resin is a polymer compound with functional groups (active groups for exchanging ions), network structure, and insolubility, usually in the form of spherical particles. The water purification treatment of nuclear power plants mainly adopts the desalination bed technology, which requires a large amount of ion exchange resins. Among them, the contaminated radioactive waste resins need to be cemented or put into high integrity containers (HIC) for permanent storage; A large number of waste resins (such as in the radioactive waste liquid treatment system, that is, the APG system) can be recycled and temporarily stored. After cleaning and release, these resins can be chemically or ionically regenerated to minimize waste and promote environmental safety. At the sam...
