A new type of low-enriched uranium fuel (LUE) is intended to allow high-performance nuclear investigation and experimental reactors which use highly-enriched uranium fuel (HEU) to be transitioned to low-enriched uranium. The University of Tomsk Research Reactor (IRT-T) has successfully completed analysis and construction simulations for transformation to LEU, and HEU, which is utilized as a nuclear fuel source, is being demonstrated further in this research. Nuclear nonproliferation approaches are demonstrated in reactor issues due to uncertainties. Experimenters propose the conversion of HEU reactors to LEU in order to adulterate HEU iterative reactors. In this investigation, Points of development, problems encountered, and views are all covered in depth.
