Using stable heat transferring theory, a thermo hydraulic model has been built, which has considered the influence of the core temperature and cooling hydrogen temperature.

采用稳态传热的理论，建立了考虑定子铁心温度的定子绕组温度水力模型。

Are the rods the only danger, or are there other components, like cooling tanks or hydrogen containers, that are also dangerous with radioactive meltdown?

随着反应堆的融化是就只有燃料棒是危险的还是其它反应堆的成分例如冷却池、氢容器也是危险的？

That was to prevent a repeat of the hydrogen explosions that blew radiation out of the plant soon after cooling systems failed in the wake of the tsunami.

海啸发生之后冷却系统失效导致了氢气爆炸，这把放射物吹出了核电站，注入氮气的行为就是为了防止这一悲剧再次发生。

Cooling problems have resulted in damage to radioactive fuel rods, hydrogen gas explosions, fires and radiation releases.

WSJ: GE Steps Up Aid in Reactor Crisis

Hydrogen is building up because, due to low levels of cooling water, fuel rods are partially exposed, causing them to overheat.

BBC: Japan quake: Nitrogen pumped into nuclear reactor

That was to prevent a repeat of the hydrogen explosions that blew radiation out of the plant soon after cooling systems failed in the wake of the tsunami.
