Abstract

FIELD: radiation safety. SUBSTANCE: method of deactivating iron-carbon alloys contaminated with radioactive matters consists in that alloy is heated in presence of sodium-containing substances supplemented with potassium and sulfur, whereupon surface is cleansed. In the event deactivation degree is not sufficient, substance is once more applied onto surface of alloy and the both are heated. EFFECT: simplified procedure.

Изобретение "СПОСОБ ДЕЗАКТИВАДИИ ЖЕЛЕЗОУГЛЕРОДИСТЫХ СПЛАВОВ" относится к технологии обработки материалов с радиоактивным загрязнением. Способ дезактивации железоуглеродистых сплавов с радиоактивным загрязнением заключается в том. что сплавы нагревают в присутствии веществ, содержащих натрий и очищают поверхность, в вещество дополнительно вводят калий и серу. В случае получения недостаточной степени дезактивации, вещество повторно наносится на поверхность сплава, они совместно нагреваются, охлаждаются и поверхность очищается.The invention "METHOD FOR DEACTIVADIUM OF IRON-CARBON ALLOYS" relates to the technology of processing materials with radioactive contamination. A method for deactivating iron-carbon alloys with radioactive contamination is. that the alloys are heated in the presence of substances containing sodium and clean the surface, potassium and sulfur are additionally introduced into the substance. If an insufficient degree of deactivation is obtained, the substance is re-applied to the alloy surface, they are jointly heated, cooled and the surface is cleaned.
