REGULATION BAR DEVICE FOR NUCLEAR REACTOR

摘要

A control rod having a center of thermal neutron absorbing material is provided specifically for use within the core of a nuclear reactor, extending through the central zone of maximum flux density. The center is formed of a plurality of portions, normally three, arranged end to end and defining joins therebetween. A central one of said portions extends continuously through the zone of maximum flux density with the joins located outward of this zone.
