论文摘要
在初始阶段,波动反应器的发展将以波核燃烧模式(WNC)运行,需要研究WNC燃料模式的动力学时,当更改两个外部参数(外部中子中子源的通量密度,热传热的热参数的通量密度,热传递的热参数)和内部参数(燃料组合物材料参数,延迟中立)。为了确认WNC富集的可能性,我们研究了其对WNC标准在PU239中不同富集的Th232的标准及其在“点火”阶段的行为。为了确认根据中子能量的慢速WNC标准的实现,我们考虑了中子能量的热和上皮区域中的延迟中子(0.015-10 ev),对thor燃料WNC模式动力学进行了数值模拟。
At the initial stage, the development of wave reactors, which will operate in the mode of wave nuclear burning (WNC), requires the study of the kinetics of the WNC fuel mode when changing both external parameters (flux density of an external neutron source, thermal parameters of heat transfer) and internal parameters (fuel composition, reactor material parameter, delayed neutrons). In order to confirm the possibility of WNC with enrichment, we study its impact on the criterion of WNC for thorium fuel Th232 at different enrichments in Pu239) and its behavior during the "ignition" stage. To confirm the fulfillment of the criterion of slow WNC depending on the neutron energy, we perform a numerical simulation of the thorium fuel WNC mode dynamics, taking into account the delayed neutrons in the thermal and epithermal regions of the neutron energies (0.015-10 eV).
