摘要
Abstract
This paper studied a method of substitution, which substituted the non-toxic chlorotrimelthylsilane （Me3SiC1） /sodium iodide （NaI） for the acutely toxic dimethyl sulphate （DMS） as a dealkylating agent for the first time to react with phosphate methylesters in preparing the gaseous radioactive methyl iodide. Comparative tests were carried out between substitution method and DMS method to measure respective cleaning efficiencies of iodine absorber both in lab and in the ventilation system of nuclear power plant. The impact of the substitutes on the organic material components of methyl iodide generator was also evaluated. The results showed that the substitution method was comparable to the former DMS method, and the substitutes was also compatible with the generator. Therefore, the substitution method can be preliminary judged applicable to both workshop and in-place tests of iodine adsorber in nuclear power plants.关键词
