Steam generated by the heat of a cooling down reactor has enough force to run a turbine, which then runs a pump that provides coolant to the core.

由冷却的反应堆产生的蒸汽足够运行一台涡轮机，然后该涡轮机运行一台水泵为反应堆提供冷却剂。

Without any electricity, the pumps won't be able to pump water through the hot reactor cores to cool them.

水泵在没有电力的情况下将无法工作，这样热反应堆堆芯就无法得到冷却。

Tepco is developing a few measures, including a system that would pump groundwater away from the reactor buildings so there would be less contaminated liquid to deal with, and another that would remove all radioactive elements from the water so it could be released safely into the environment.

WSJ: Leaks Rouse Fears at Japanese Nuclear Plant

So far, the three Japanese reactors experiencing cooling problems haven't released significant amounts of radiation, but the situation is dangerous, as an explosion Monday morning in Japan damaged a pump bringing in cooling seawater at one reactor and a third reactor began experiencing cooling problems Monday afternoon.
