The utilisation of nuclear heating for application to various oil refinery processes is being considered in Russia. Thermal power is required at different medium-range temperatures for different operations. These include low-temperature processes up to 400°C associated with initial reprocessing of oil products, e. g. hydrocracking, hydrocleaning. There are also middle-range temperature processes up to 600°C associated with secondary oil refining processes, reforming, cracking, etc. The VGM-P, HTR-10 and BN-600 systems, described below, are seen as possible candidates for this application.
