摘要:
A generally cruciform-shaped control rod for a nuclear reactor is formed by vertical stiffeners laterally spaced one from the other and interconnected by horizontal stiffeners at their ends defining discrete compartments in each wing of the cruciform-shaped control rod. Sheathing overlies the stiffeners to seal each of the compartments from its surrounding environment. Neutron-absorbing material, such as boron carbide and/or hafnium tubes, are disposed in each compartment. Each wing is secured to a generally cruciform central tie rod formed of planar plates superposed one over the other alternately at right angles with the outer edges of the plates welded to the inner edges of the wings, affording structural support to the control rod. The innermost vertically extending stiffeners have apertures communicating between adjacent compartments whereby helium gas generated by the boron-neutron reaction in the boron capsules leaks from the boron capsules into each compartment thereby equalizing the pressure across each wing of the control rod.
