摘要

The paper reviews the status of work by the NIKIET JSC (Moscow, Russian Federation) in the area of developing fuel assemblies (FAs) for various types of research reactors under construction and operation in our country and abroad. For the PIK high-flux reactor, advanced fuel and burnable absorber rods, as well as FAs were designed and justified. Their application will extend the operation of the reactor at rated power with the required process characteristics. An advanced modification of the VVR-M2 FA was developed and justified for the RB-01 reactor. The set of computational and experimental justifications confirms the performance of developed FAs in relation to its operating conditions. Advanced modifications of IRT-4M and VVR-M2 FAs were confirmed feasible for use in operated research reactors. The main results of the work on the performance justification of an advanced FA design with plate fuel elements are presented.
