ABSTRACT:
An annular burnable absorber rod which minimizes the displacement of cooling water from a nuclear reactor core is disclosed. The rod is constructed from a pair of concentric tubes providing a sealed annular space therebetween. A tubular support having a layer of zirconium diboride deposited by chemical vapor deposition is located within the annular space and protected against corrosion.
