Conversion of RBT Research Reactors to a New Fuel Type
https://doi.org/10.1134/S2304487X20040082
Abstract
The replacement of old-type fuel with the new one in the existing RBT reactors, which use spent fuel from the SM reactor converted to uranium-rich fuel after refurbishment, has been discussed. The procedure to convert the reactor to a new fuel is thoroughly described since it is not provided in the reactor regular operation and is not regulated by safety documents. The reactor core loading with new and old fuels in quantitative and percentage terms at the beginning of 2019 is demonstrated. It is shown that the calculated efficiency of RBT control rods does not exceed the designed limits. Attention is paid to the training of personnel engaged in the conversion to the new fuel. Conclusions are made about the safe operation of a new-type fuel, correctness of the selected procedure, and the further possibility of converting the RBT reactors to the new fuel.
