论文摘要
大多数Tokamak设备（包括ITER）由于其高反应性而利用D-T反应，但是由相关的14MEV中子引起的壁负荷将限制高β高β融合性能的进一步发展。为了探索P-11B融合循环，由于电子温度接近电子的剩余能量，因此扩展了Tokamak系统代码以纳入相对论的Bremsstrahlung。通过选择最佳的P-11B混合和离子温度，在忽略同步型辐射损耗时，在热壁加载极限和β限制下发现了P-11b Tokamak反应堆的某些代表性参数集超过1。但是，当考虑同步辐射损失的影响时，融合会大大减少。氦灰在融合性能中也起着重要作用，我们发现氦限制时间必须低于能量限制时间，以使氦气浓度比率保持在可接受的范围内。
Most tokamak devices including ITER exploit the D-T reaction due to its high reactivity, but the wall loading caused by the associated 14MeV neutrons will limit the further development of fusion performance at high beta. To explore p-11B fusion cycle, a tokamak system code is extended to incorporate the relativistic bremsstrahlung since the temperature of electrons is approaching the rest energy of electron. By choosing an optimum p-11B mix and ion temperature, some representative sets of parameters of p-11B tokamak reactor, whose fusion gain exceeds 1, have been found under the thermal wall loading limit and beta limit when synchrotron radiation loss is neglected. However, the fusion gain greatly decreases when the effect of synchrotron radiation loss is considered. Helium ash also plays an important role in the fusion performance, and we have found that the helium confinement time must be below the energy confinement time to keep the helium concentration ratio in an acceptable range.
