    摘要： As an organic iodine remover that removes organic iodine in a containment vessel of a nuclear reactor, an organic agent (for example, an ionic liquid, an interfacial active agent, a quaternary salt, or a phase transfer catalyst) having a function of dissolving and decomposing the organic iodine and retaining iodine is used. The organic iodine remover is a substance composed of a cation and an anion. The organic iodine remover, is, in particular, an organic iodine remover in which, in a structure of the cation of the organic agent, carbon or oxygen is bonded to, via a single bond, to a phosphorus element, a sulfur element or a nitrogen element, the number of carbon chains is 2 or more, and an anionic structure is configured with a substance with high nucleophilicity. By using the organic agent having such a configuration, the organic iodine is removed with an efficiency of 99% or more.

    摘要： The present invention provides an organic iodine trapping apparatus and an organic iodine trapping method capable of efficiently trapping organic iodine in a nuclear reactor container vessel. There is provided an organic iodine trapping apparatus (100) that traps organic iodine in a nuclear reactor container vessel (10), including: a liquid vessel (1) containing a non-volatile liquid (L1) (Example: ionic liquid, interfacial active agent solution and the like) capable of decomposing organic iodine; and an introduction pipe (2a) for introducing a fluid containing organic iodine in the nuclear reactor container vessel (10) to the non-volatile liquid (L1), in which the non-volatile liquid (L1) is heated by heat in the nuclear reactor container vessel (10) or reaction heat of the fluid in the nuclear reactor container vessel (10), and then decomposes and traps the organic iodine. There is provided an organic iodine trapping method including: heating a non-volatile liquid (L1) capable of decomposing organic iodine by heat in the nuclear reactor container vessel (10) or reaction heat of fluid in the nuclear reactor container vessel (10); making the fluid containing organic iodine pass through the heated non-volatile liquid (L1); and decomposing and trapping the organic iodine in the non-volatile liquid (L1).
