nuclear heat energy

The energy released by the nuclear reaction is transformed into heat.

核反应中释放出来的能被转变为热。

During a nuclear fission chain reaction, the tubes heat up to extremely high temperatures, and the way to keep them safe turns out to also be the way to extract useful energy from them.

核裂变连锁反应发生时，导管被加热到极其高的温度，将热量安全导出则意味着可以提取裂变产生的可利用能量。

Other nuclear plants across the country have been shut down for emergency safety tests over the summer, usually the time of peak energy demand in Japan due to the heat and humidity.

日本的其它核电站在这个夏天被紧急关闭以进行安全检查，因为夏天闷热的天气，所以用电量比较大。
