The Yucca Mountain Nuclear Waste Dump is being revived, but it is complicated.
After creating nuclear waste for 40 years with no regulation or plan, Congress passed the Nuclear Waste Policy Act of 1982. It was the official recognition of the fact that nuclear energy activities created toxic radioactive substances that had to be thoroughly isolated for a very long time from contact with living things. The Act established that radioactive waste should be deposited deep in geological “repositories”. After years of studies ( and plenty of politics) they eventually decided on Yucca Mountain in Nevada. In the 2010 Harry Reid got Obama to halt the Yucca Mountain project due to local opposition. Of course, it never hurts a President to do a big favor for the Senate leader of their party.
