Idaho's Secretive Nuclear Breakthrough World's First Power Plant

Idaho’s claim to nuclear fame is the Experimental Breeder Reactor-I (EBR-I), the first reactor to generate usable electricity from nuclear fission. This milestone happened in 1951, but EBR-I was an experimental reactor, not a power plant — that title belongs to Obninsk in the USSR (1954) or Calder Hall in the UK (1956).

Idaho’s Nuclear Legacy

Idaho has played a crucial role in nuclear history. Home to the first reactor to generate usable electricity, the state has been a pioneer in harnessing nuclear energy. Let’s explore some key locations that have contributed to this legacy.

Experimental Breeder Reactor-I (EBR-I) This site is where it all began. EBR-I, located near Arco, Idaho, was the first nuclear reactor to generate electricity. In 1951, it lit up four light bulbs, marking a significant milestone in nuclear energy. Today, it’s a museum where visitors can learn about the history and science of nuclear power.
Idaho National Laboratory (INL) INL is a leading center for nuclear research and development. It has been at the forefront of nuclear innovation since its establishment. The lab works on advanced nuclear technologies, including reactor designs and nuclear waste management. It’s a hub for scientists and engineers pushing the boundaries of what’s possible with nuclear energy.
Arco, Idaho Arco holds the distinction of being the first city in the world powered by nuclear energy. In 1955, the nearby BORAX-III reactor supplied electricity to the town, showcasing the potential of nuclear power for civilian use. Arco’s unique history makes it a fascinating stop for those interested in nuclear energy.
Advanced Test Reactor (ATR) Located at INL, the ATR is a key facility for testing nuclear materials and fuels. It plays a vital role in ensuring the safety and efficiency of nuclear reactors worldwide. Scientists from around the globe come to ATR to conduct experiments that help improve nuclear technology.
Naval Reactors Facility (NRF) Part of INL, the NRF supports the U.S. Navy’s nuclear-powered fleet. It provides training and testing for naval reactors, ensuring the safety and reliability of nuclear-powered submarines and aircraft carriers. The facility is crucial for maintaining the Navy’s operational capabilities.
Lost River Valley This scenic valley near Arco is not only beautiful but also significant in nuclear history. It’s near where tests of nuclear-powered aircraft engines took place as part of the Aircraft Nuclear Propulsion program. While the project was eventually abandoned, it demonstrated the potential of nuclear propulsion for aviation.

Idaho’s contributions to nuclear energy are vast and varied. From pioneering reactors to cutting-edge research, this state has been a leader in the nuclear field.
