为新反应堆选址虽并不容易(这导致旧反应堆仍在入网发电)，但看起来也并非毫无可能。

Finding sites for new reactors was not proving easy-and old reactors stayed online as a result-but it did not seem impossible.

与此同时，核能运营商通过所谓的“提高额定值”方式，即提高原定的发电量，延长核设施原定的运行时间，不断压榨旧反应堆的剩余价值。

Nuclear operators, meanwhile, squeezed new life out of old reactors through so-called "uprating" — running plants longer and at higher power outputs than originally intended.

经过了20年的光阴，旧填充物表面有95%的汞元素已经发生了化学反应，它变成了黑辰砂(beta - mercury sulfide)，一种黑色的固体。

After two decades, 95 percent of the elemental mercury on the surface of a filling had gone through a chemical reaction. It became beta-mercury sulfide, a black-colored solid.
