When nuclear plants were designed, says Wald, regulators anticipated that spent fuel rods would sit in cooling water pools for five years and then be chemically processed and turned into plutonium.
沃尔德说，当一开始设计核电厂时，监管机构预计，乏燃料棒应该存放在冷却水池里，五年以后捞出来，再经过化学处理而转化为钸。
That means cooling water is not getting to the reactor core, causing a build up of steam inside the containment vessel.
这意味着冷却水并没有进入反应堆核心，从而导致了安全壳内的气压上升。
The document also recommends that engineers continue adding boron to cooling water to help prevent the cores from restarting the nuclear reaction, a process known as criticality.
