The last two remaining SovRoms, "Sovrompetrol" and "Sovromcuarț", were disbanded in 1956. However, the Romanian government signed an agreement that would replace "Sovromcuarț" with a new state-owned company which was to carry on the extraction and processing of uranium ore, delivering its entire output to the Soviet Union. This successor company was itself dissolved in 1961. Soviet investment in "Sovromcuarț" was evaluated to a debt of 413 million rubles, which were to be paid by Romania over a 10-year period (starting with 1961).
