Russia jumped in earlier this year by supplying nuclear fuel to India, claiming "safety" as a reason for providing uranium to an Indian reactor that could simply have been shut down.
今年早些时候，俄罗斯跳出来给印度提供核燃料并声称“安全”，因为提供给印度的铀用于可简单关闭的反应堆。
By noon, the owners had shut down both the damaged and undamaged cooling towers and had cut the plant's electricity output in half to avoid any harm to the reactor.
电厂的管理者已经在正午之前，要求关闭了所有的冷却塔(包括损坏的和未损坏的)，并将电厂的电力供应下调一半，以此避免对核反应堆造成任何损害。
Because the reactor had been shut down a long time ago, the decay heat had decreased to a significantly lower level, so the pressure in the plant stabilized, and venting was no longer required.
因为反应器已经关闭了很长时间，残余热量下降到了一个显著的低水平，因此工厂内部的压力已经稳定，不再需要继续排气。
Control rods are used in a PWR typically to change the power level and also to shut down the reactor.
