Different spent nuclear fuel processes will evolve residual heat. Its removal is necessary to avoid overheating of the fuel or radioactivity hazard. Thus, nuclear energy raises the residual heat removal problems. Although a variety of the world's scientists have proposed a range of waste heat recovery method, however, due to their ability, they cannot yet be applied in practice. Thus, the work focuses on one of the spent nuclear fuel waste heat recovery method and tested based on its usefulness. It is likely that in the future using similar methods to create a safe and efficient fuel waste heat recovery technology would enable to compensate for the spent nuclear fuel storage and handling costs incurred. The object of this work - the existing fuel system modification, and the goal - to modify existing fuel handling system, adapting it to the residual heat utilization. The work consists of introduction, three parts and conclusions. The first part describes the theoretical fuel residual heat causes, usability and fuel processing technology, the second - describes modified fuel waste heat recovery technology, and the third - presented the container and its integrated heat exchanger thermalhydraulic calculations. In the end of the work submitted conclusions. Because of lower costs and time resources, the existing fuel system modification, rather than a new building, is especially useful in order to effectively utilize the residual heat. Replacing the fuel storage system and creation of waste heat recovery technology, it was to combine dry and wet storage methods - the nuclear fuel is placed in a dry container, which integrates the residual heat of the container designed to remove water-water heat exchanger. In order to justify the modified fuel residual heat technology performance has been carried out thermalhydraulic calculations, which show that the application of this system has the potential, but it requires additional calculations. |
