FIELD: process engineering.
SUBSTANCE: invention relates to separation of uranium isotopes by gas centrifuging process. This process consists in emergent evacuation of the portion of gas from processing section via light-fraction pipeline. Note here that in operation of the cascade process sections in separation of uranium isotopes, manual valves at light-fraction pipelines are permanently open while those at heavy-fraction pipes and feed pipes are permanently closed. Actuator is automatically opened at occurrence of emergency to remove light impurities and destruction products along with uranium hexafluoride into extra unit.
EFFECT: efficient separation in emergency, optimum automation of filling of gas centrifuges after emergent evacuation.
