DEVICE FOR DETECTING DEFECTIVE FUEL ASSEMBLIES OF THE REACTOR

Category of development 
Nuclear energy
The essence of development. Purpose and scope 
The secured decision is aimed at increasing the efficiency and reliability of the control system of the leakproofness of the fuel assemblies of the reactor. The device belongs to the field of control of safety of operation of nuclear fuel (NF), in particular to the system of control of tightness of fuel assemblies (FA) water reactors.
The main advantages 

 

The use of a specially designed two-phase fine-dispersed flow makes it possible to increase the efficiency of flushing of fission products from the claddings of fuel rods.

The organization of repeated circulation of air and water in the volume of RS, allows to avoid dilution of activity in the process of leak testing, which increases the quality and reliability of the control.
The degree of readiness. Protection of intellectual property 

The basic elements of the installation have been developed and experimental studies have been carried out. The technology is protected by the patent of Ukraine.
