Tritium well depth, tritium well time and sponge mechanism for reducing tritium retention

摘要: New simulation results are predicted in a fusion reactor operation process. They somewhat similar to, but quite different from, the xenon poisoning effects resulting from fission-produced iodine during restart-up process of fission reactor. We obtained completely new tritium well depth and time magnetic confinement energy research area. This study is carried out to investigate following: what will be least amount storage required start up how long needs operated for achieving break-even initial start-up phase due finite tritium-breeding time, which dependent on breeder, specific structure breeding zone, layout coolant flow pipes, recovery scheme applied extraction process, retention plasma facing component (PFC) other components, unrecoverable fraction leakage inertial gas container natural radioactive decay constant. describe these issues answer problems by setting solving set equations, described dynamic subsystem model inventory evolution experimental breeder (FEB). Reasonable using our model. It found that about 0.319?kg approximately 235 full power days reference case designed FEB configuration, it also after one-year reaches 0.767?kg, more than another FEB-like The show PFC equivalent 11.9% fairly consistent with result 10?20% deduced integrated particle balance European tokamaks. Based theoretical studies, some mechanisms proposed reducing materials blanket. In this paper, qualitative analysis 'sponge effect' out. may help us reduce ~20% PFC.
