METHOD AND FACILITY FOR BRAKING THE CLASTERS OF THE FUEL HOLDERS OF EXPERIMENTAL NUCLEAR REACTOR IN CASE OF THE CRASH FALL IN THE ACTIVE ZONE

摘要

The invention addresses the inhibition and soft fit of clustersnuclear fuel cartridgesreactor during their fall into the reactorzone.A method of inhibiting experimental fuel cartridge clustersnuclear reactor at emergencyfalling into the core is marked bythat the braking of the clusters is hampered by the braketorque of stepper motor and increasedby pulling the cable unwound from the larger strand diameterdifferential drum at its momenttransition from large to small. Equipmentto carry out this method is indicatedby making the clusters suspended over the pulleywith a cord on a stranded differential drumcoupled via a rotary gear mechanismstepper motor.Vynélezu can be used without modification in Schoolor experimental nuclear reactorsas a control or emergency deviceprotection. Some adjustments would bethe principle of the invention can be applied tosolving work movements of some eartha stavebn
