( 5) СПОСОБ УНИЧТОЖЕНИЯ ОТХОДОВ ЩЕЛОЧНЫХ (5) METHOD FOR DESTRUCTION OF ALKALINE WASTE
1one
Изобретение относитс к металлур- гической, химической промышленности и атомной энергетике, в частности к эксплуатации атомных станций с реактором на быстрых нейтронах.The invention relates to the metallurgical, chemical and nuclear industries, in particular, to the operation of nuclear power plants with a fast neutron reactor.
Известен способ уничтожени отходов щелочных металлов с поверхности оборудовани с использованием волы, дл чего вначале емкость продувают аргоном, а-затем снизу вместе с аргоном подают воду до полного заполнени емкости, и давление аргона в емкости поддерживают на 0,15-0,20 мм вод.ст. выше давлени столба воды при ее верхнем уровне в емкости 1A known method for the destruction of alkali metal wastes from an equipment surface using an ox, for which the tank is first flushed with argon, and then water is supplied from the bottom together with argon until the tank is completely filled, and the pressure of argon in the tank is maintained at 0.15-0.20 mm of water .st. above the pressure of the water column at its upper level in the tank 1
Этот способ имеет р д существенных недостатков: нейтрализаци натри происходит мгновенно, при этом натрий плавитс и разбрызгиваетс по стенкам емкости вместе с раствором . щелочи; выше уровн во.цы на стенках емкости образуетс концентрированна щелочь, а стенки емкости разогреваютс до температуры выше 150°С, что приводит к щелочной хрупкости аустенитных нержавеющих сталей} дл проведени процесса цейтрализации натри водой внутренние стенки емкости необходимо плакировать материалом МЕТАЛЛОВThis method has a number of significant drawbacks: the neutralization of sodium occurs instantaneously, while sodium melts and splashes along the walls of the container along with the solution. alkalis; Above the water level, concentrated alkali is formed on the vessel walls and the vessel walls are heated to a temperature above 150 ° C, which results in alkaline brittleness of austenitic stainless steels} to conduct a process for the neutralization of sodium with water, the internal walls of the vessel must be plated with METAL material
типа инконель, так как неплакированные емкости, изготовленные из аустенитных сталей, выход т из стро из-за коррозионного воздействи ;про5 дувка .емкости аргономi и поддержание в ней избыточного давлени приводит к расходу большого количества аргона и требует полной герметичности, увеличива веро тность выхода из емкости и попадани в воздух рабочего помещени радиоактивных аэрозолей. Известен способ уничтожени щелочных металлов с использованием воды , согласно которому растворениеsuch as inconel, since uncladded containers made of austenitic steels fail due to the corrosive effect; blowing argon capacitance and maintaining excessive pressure in it leads to a large amount of argon consumption and requires complete tightness, increasing the likelihood of containers and airborne radioactive aerosols. A known method for the destruction of alkali metals using water, according to which the dissolution
15 щелочного металла производ т под слоем инертной жидкости, имеющей температуру кипени ниже 40С. Такой инертной жидкостью вл етс эфир 2 . Данный способ применим дл растворени малых количеств щелочных металлов и в основном используетс при химическом анализе, дл растворени же килограммовых количеств щелочных металлов способ не приемлем в виду15 alkali metals are produced under an inert liquid layer having a boiling point below 40 ° C. Such an inert liquid is ester 2. This method is applicable for dissolving small amounts of alkali metals and is mainly used in chemical analysis, but for dissolving kilogram quantities of alkali metals, the method is not acceptable.
25 необходимости использовани больших количеств сравнительно дорогосто щего эфира.25 need to use large quantities of relatively expensive ether.
Известен также способ уничтожени отходов щелочных металлов с исполь л зованием воды и минерального масла.There is also known a method for the destruction of alkali metal wastes using water and mineral oil.
