Abstract

PURPOSE: To prevent a fuel ball from damage, by operating a control of neutron flux distribution in the core and output, in the method how to take range of withdrawing a migration reflector 5 of the top reflector.
CONSTITUTION: A core 1, comprising many fuel balls, is surrounded by a top reflector 2, side reflector 3 and bottom reflector 4. In the interior of the top reflector 2, are provided a plurality of top reflector guide tubes 7 for making an up-down movement of the migration reflector 5 partially of the top reflector 2 in a case with a signal generated for controlling core neurron flux distribution and output. As a withdrawl range of the migration reflector 5 of the top reflector 2 is varied, a neutron flux distribution in the core and output are also varied.
