Description

The release of 137Cs into an Ar flow during the interaction of 137CsI and 137CsOH-137Cs2CO3 with molten lead at a temperature of ~852 K was studied. During the heating of Pb0 with 137CsI, 137CsOH- 137Cs2CO3, and 137CsI-137CsOH-137Cs2CO3, from 2 to 8% of 137Cs can pass into the gas flow. Based on the distribution of 137Cs between the elements of the gas purification system, it was concluded that the chemical and disperse composition of compounds containing 137Cs in the gas phase is quite heterogeneous. Volatile 137Cs compounds formed upon heating 137CsI, 137CsOH-137Cs2CO3, and 137CsI-137CsOH-137Cs2CO3 with Pb0 in a gas flow at ~852 K can contain both charged aerosols and aerosols without electric charge.

Abstract (Russian)

Исследован выход 137Cs в поток Ar при взаимодействии 137CsI и 137CsOH-137Cs2CO3 с расплавленным свинцом при температуре ~852 К. Установлено, что в процессе нагрева Pb0 с 137CsI, 137CsOH-137Cs2CO3 и 137CsI-137CsOH-137Cs2CO3 в газовый поток может перейти от 2 до 8% 137Cs. На основании распределе-huh137Cs по элементам системы газоочистки сделан вывод о том, что химический и дисперсный состав соединений, содержащих 137Cs, в газовой фазе достаточно неоднороден. При этом летучие соединения 137Cs, образующиеся при нагреве 137CsI, 137CsOH-137Cs2CO3 и 137CsI-137CsOH-137Cs2CO3 с Pb0 в газовом потоке при ~852 К, могут содержать как заряженные аэрозоли, так и аэрозоли без электрического заряда.
