ADVANCED TEST REACTOR 1960s “For 50 years, the Advanced Test Reactor has served the American taxpayer, enhancing national security by keeping nuclear-powered submarines at sea for their lifetimes, and driving an evolution of nuclear energy into a power source that provides 19 percent of this nation’s electricity. The good news? With regular maintenance and upgrades, ATR will continue to be the test reactor of choice for decades to come.” –Lt. Gov. Brad Little 1 3 4 2
