Investigations of regularities in the accumulation of hydrogen-reduced slags in circulation circuits with lead-containing coolants

The paper presents a computational analysis of regularities in the accumulation slags during interaction lead and lead-bismuth coolants with oxygen gas. Oxidation lead-containing will cause formation oxide, while bismuth oxide is unlikely. Dosed supply oxidizing gas to makes it possible oxidize, selectively, chromium nickel their oxides without slag from solid oxide. Regularities were studied which are involved It has been found that, process interacting gas, alloy oxidized 1.7 times as intensively lead, this being explained by presence alloy. Bismuth more than both inert overpressure depressurization does not prevent air entering circuit, dependence nitrogen flow into circuit on argon out loop close linear regardless state (cold, coolant; heated, circulating coolant). Oxygen chemically active impurity absorbed circuit; therefore important control spaces reactor research plant circuits coolants. This make signal, timely manner, ingress take measures required avoid or reduce scale oxides.
