Abstract

FIELD: atomic power engineering. SUBSTANCE: process involves metallization of irradiated graphite with double and thin layer "copper-nickel" to ensure water tightness, minimization of leaching of radionuclides located inside and facilitated handling with them due to elimination of problems related to oiliness of surface. Metallization is conducted by the method of chemical autocatalytic reduction of salts of metal present on surface of graphite where catalyst was preliminarily precipitated and activated. EFFECT: enhanced efficiency.

Способ нанесения металлизированного покрытия на радиоактивный графит с действующих или демонтируемых атомных станций состоит в металлизации облученного графита двойным и тонким слоем медь-никель с целью обеспечения водонепроницаемости, минимизации выщелачивания радионуклидов, находящихся внутри, и облегчения обращения с ним за счет устранения проблем, связанных с маслянистостью поверхности. Металлизацию проводят методом химического автокаталитического восстановления солей металла, находящихся на поверхности графита, где предварительно был осажден и активирован катализатор.A method of applying a metallized coating to radioactive graphite from operating or dismantled nuclear plants is to metallize irradiated graphite with a double and thin layer of copper-nickel to ensure water tightness, minimize leaching of the radionuclides inside, and facilitate handling by eliminating problems associated with oiliness surface. Metallization is carried out by the method of chemical autocatalytic reduction of metal salts located on the surface of graphite, where the catalyst was previously precipitated and activated.
