UDC 621.039.538

A method of revealing the fact of existence (absence) 
of a local region in the reactor core with an anomalous value of the 
multiplication factor, detection of this region, and on-line monitoring 
of its "movement" throughout the volume of the core of a shut-down 
reactor during the entire period of overloading is proposed.
