Amazing little museum outlining early days of atomic power - first practical electrical plant now converted to a museum. Self guided tour was great and it is FREE! Worth a couple hours.

For those of a technical bent, the story behind developing and operating the first Liquid Sodium/Potassium cooled Breeder Reactor was very interesting and informative. Unfortunately this techology never became commercialized due to concerns about converting Uranium into Plutonium (Terrorists would love to get there hands on the latter!), and engineering problems dealing wih liquid sodium/potassium coolant (creates a big explosion in the presence of water). By far, the oddest thing to see is a pair of nuclear reactors which were designed to power a very large bomber aircraft keeping it aloft for weeks at a time. The program was cancelled in the early 60s due mainly to the inability to provide adequate radiation shielding for the crew.

Take the tour; our tour guide was very informative and explained everything as we went along. Then if you have time go back and look at everything again. There's so much to absorb. It's amazing how far we've come.

Following WW2 scientists and engineers were working on ways to use nuclear energy to produce electricity. ERB1 was at the cutting edge of this quest. You can take a self-guided tour or take a tour with a guide which lasts about an hour. We chose the latter.

The tour was interesting and focussed on the human aspect of the work rather than the physics (Origin of word SCRAM for example).

The tour is free.

The museum is just off highway 20 between Idaho Falls and Arco and is well worth a visit.

If you're going to Craters of the Moon, take the time to visit this free museum. It is very well done, easy to understand and has great staff. A new exhibit on the ERB 2 (successor to ERB 1) talks about Three Mile Island, Chernobyl and the recent Fukushima reactor problems and how if they were built with ERB 2 technology there never would have been any problems like there were.

Don't miss the 3 outside displays. They talk about the USAF's plans to build nuclear powered bombers and have 2 of the test units.
