Some Nuclear Facts More than 100 nuclear More than 100 nuclear power plants supply about 20 percent of the electricity in the U.S.

Nuclear materials are used in medicine for diagnosis d

t and cancer treatment.

Nuclear materials are widely used in industry widely used in industry, such as in density gauges, flow measurement devices, radiography devices, and 13 of 15 g

Nuclear Waste

• The NRC regulates:

• The NRC regulates:

- Storage of spent reactor fuel in fuel pools or dry storage casks, and

- Any national spent fuel storage site, such as the such as the proposed Yucca Mountain site.
