How much of their fissile material capabilities are there? Some people say half. Some people say more.

那里的裂变材料生产能力有多？人认为有半。还有人认为比半还要多。

The reactors use " tristructural isotropic particle fuel" , in which blobs of fissile uranium (along with oxygen and carbon) are wrapped in layers of carbon and silicon carbide.

反应了“三结构各向同性颗粒燃料”，其可裂变铀（以及氧和碳）的斑点被包裹在碳和碳化硅层中。
