1. Способ извлечения радиоактивного битумного компаунда из хранилища с помощью локального устройства нагрева, содержащего нагревательный элемент, отличающийся тем, что извлечение битума осуществляется с помощью оборудования (приспособления), имеющего температуру, превышающую температуру плавления битума, но ниже температуры вспышки, обеспечивающего локальный нагрев по границе извлекаемого фрагмента битума, приводя битумный компаунд в состояние, пригодное для его захвата и извлечения, с последующим перемещением в контейнер извлекаемого битумного фрагмента с возможным содержанием инородных включений различного размера.1. The method of extracting a radioactive bitumen compound from the storage using a local heating device containing a heating element, characterized in that the extraction of bitumen is carried out using equipment (devices) having a temperature higher than the melting temperature of bitumen, but lower than the flash point, providing local heating for the boundary of the extracted bitumen fragment, bringing the bitumen compound into a state suitable for its capture and extraction, with subsequent movement to the container, we extract th bitumen fragment with the possible content of foreign inclusions of various sizes. 2. Способ по п. 1, отличающийся тем, что извлечение и локальный нагрев границ извлекаемого битумного фрагмента осуществляется одним и тем же нагревательным оборудованием (приспособлением), которое имеет, по меньшей мере, один вход и один выход для подвода (отвода) теплоносителя, или вход/выход для подключения ТЭНов, которые могут находиться как с наружной стороны, так и с внутренней стороны нагревательного оборудования (приспособления).2. The method according to p. 1, characterized in that the extraction and local heating of the boundaries of the extracted bitumen fragment is carried out by one and the same heating equipment (device), which has at least one inlet and one outlet for the inlet (outlet) of the coolant, or input / output for connecting the heating elements, which can be located both on the outside and on the inside of the heating equipment (device). 3. Способ по пп. 1 и 2, отличающийся тем, что нагревательное оборудование (приспособление) имеет гладкую поверхность, облегчающую последующую дезактивацию данного нагревательного оборудования (приспособления).3. The method according to PP. 1 and 2, characterized in that the heating equipment (device) has a smooth surface that facilitates the subsequent decontamination of this heating equipment (device).
