Operating Experience from Europium Absorbers in the BN-600 Reactor and Perspectives of Their Further Utilization in the Innovation Nuclear Reactors
An extensive operating experience from the europium control rods has been accumulated. Research into materials has shown that the BN-600 reactor europium rods have high lifetime characteristics. A set of the studies on utilization of europium radionuclides in the gamma-emitting sources has been conducted. The most promising line is a utilization of double-purpose designs of the control rods with an absorbing kernel in the form of the inserts of the active part of the standard gamma-emitting sources.
