Congress has approved a new national park in Washington state that commemorates the Manhattan Project at Hanford.
The defense spending bill passed by Congress Friday includes the biggest expansion of the national parks system in decades.
If this bill is signed into law by President Obama, it could bring thousands more visitors to the B Reactor at Hanford. The reactor was the first full-scale nuclear reactor and was built during World War II. 100,000 people visited the museum last year through the Department of Energy tours.
It will likely take a couple of years for the National Parks Service to get the new park up and running along with the sites at Los Alamos, New Mexico and Oakridge, Tennessee.
