The Expected Radioactive Contamination of Synthesis Gas from Process Heating Plants Lignite Gasification

Automatic translation: Nuclear energy has long been used in commercially operated light and heavy water reactors and in reactor variants of other types to generate electrical energy. In the vast majority of the Falls water vapor in the direct circuit or via a Heat exchangers generated and coupled in steam turbines Generator converted into electrical energy. In the high-temperature reactor with helium cooling can be with an intermediate heat exchanger the same way to generate electrical energy. The ones in this Reactor type achieved efficiencies are above those of Light or even heavy water reactors. Because of the high temperature level that occurs in high-temperature reactors, e.g. Zt. is already being achieved and that with certainty can still be increased, there are other methods to use this energy at a high temperature level. In addition to the process steam generation had as turned out to be favorable for chemical processes in endogenous reactions energy at high temperature level need to use nuclear generated heat. i.a. come for the cleavage of H₂O in hydrogen and Oxygen, methane fission and gasification of fossils fuels such as B. lignite in question. The presence of radioactive contaminants in the The primary cooling circuit of an HTR is due to the necessary shielding measures, monitoring and above all because of the necessary expense of a gas cleaning system represents a significant cost factor. However, the degree of radioactive contamination in the primary cooling circuit has direct influence on the radioactive contamination of the end product produced. The question of how much in the primary cooling circuit radioactive fission products contained in an HTR into the The end product of the process will therefore limit the possibilities of the technical realization of a project especially on the cost side.
