The reactor suffered a partial meltdown that was contained by the giant, pill‐shaped steel vessel containing the core.


low‐level wastes and high‐level wastes. Low level wastes consist of materials that release a relatively small level of radiation or that will soon decay to a level where they no longer present a threat to humans and the environment. High‐level wastes are a different matter. After a period of time, the fuel rods in a reactor are no longer able to sustain a chain reaction and must be removed. These rods are still highly radioactive, however, and present a serious threat to human life and the environment that can be expected to last for tens of thousands of years.

the government decided to construct a huge crypt in the middle of Yucca Mountain in Nevada for the burial of high‐level wastes
