FIELD: recovery of solid radioactive and toxic waste by combustion with subsequent inclusion of combustion products in glass materials. SUBSTANCE: the method includes fusion of glass-forming flux in a crucible furnished with an inductance coil, feeding of convergent gas flows of oxidizing gas to the zone of action the inductance coil magnetic field, initiation of plasma flame in the point of convergence of gas flows, batch feeding of solid radioactive and toxic waste to the melt surface, combustion of waste, mixing of waste ash with glass melt and cooling of the obtained mixture. EFFECT: reduced degree of entrainment of radioactive and toxic waste components, enhanced efficiency and quality of obtained product. 3 cl, 4 dwg

Способ переработки твердых радиоактивных и токсичных отходов. Область применения: переработка твердых радиоактивных и токсичных отходов сжиганием с последующим включением продуктов сгорания в стеклообразные материалы. Сущность способа: способ включает плавление стеклообразующего флюса в тигле, снабженном индукционной катушкой, подачу в надрасплавное пространство в зону действия магнитного поля индуктора сходящихся газовых потоков окисляющего газа, инициирование возникновения плазменного факела в точке схождения газовых потоков, порционную подачу твердых радиоактивных и токсичных отходов на поверхность расплава, сжигание отходов, смешение золы отходов со стеклообразным расплавом и охлаждение полученной смеси. Способ позволяет снизить степень уноса радиоактивных и токсичных компонентов отходов, повысить экономичность проведения способа, а также повысить качество получаемого продукта.A method of processing solid radioactive and toxic waste. Scope: processing of solid radioactive and toxic waste by burning with the subsequent inclusion of combustion products in glassy materials. The essence of the method: the method includes melting a glass-forming flux in a crucible equipped with an induction coil, supplying convergent gas flows of oxidizing gas to the super-melt space of the magnetic field of the inductor, initiating the appearance of a plasma torch at the point of convergence of gas flows, portioned supply of solid radioactive and toxic waste to the surface melt, waste burning, mixing waste ash with a glassy melt and cooling the resulting mixture. The method allows to reduce the degree of entrainment of radioactive and toxic components of the waste, increase the efficiency of the method, and also improve the quality of the resulting product.
