摘要

核电站产生的大部分电力来自压水核反应堆。目前，压水堆的主要燃料是浓缩铀。热能是由铀235使用慢(热)中子裂变产生的。第四代反应堆已经在考虑利用快中子从铀238的裂变中获取热能。中子与核反应堆中的物质同时发生相互作用。相互作用的概率和模式取决于中子能量。因此，本文的研究重点是利用SVICKA实验站充气探测器的反应速率测量中子能谱和中子场分布。

The spectrum of neutrons and its importance for nuclear power engineering

Most of the electricity produced in nuclear power plants comes from pressurized water nuclear reactors. Currently, the main fuel of pressurized water nuclear reactors is enriched uranium. The thermal energy is produced by fission of uranium 235 using slow (thermal) neutrons. Generation IV reactors are already contemplate obtaining thermal energy from the fission of uranium 238 using fast neutron. Neutrons interact simultaneously with materials present in a nuclear reactor. Probability and mode of interaction depend on the neutron energy. Therefore, the paper focuses on the measurement of neutron spectra and neutron field distribution using the reaction rate a gas filled detector in experimental stand SVICKA.
