What can you do with a nuclear power plant that was never completed? Turn the massive concrete structures into a world-class acoustical test facility. The Satsop Nuclear Power Plant was 75% complete in 1983 before the money ran out and work was abandoned. It was one of the largest bond defaults in history. To avoid steep dismantling costs, the site was eventually handed over to a public corporation and became the Satsop Development Park, home to various light industry businesses who work in the shadows of the two cooling towers. You can enter the property freely but you can't go under the towers (they're fenced off, although supposedly they are planning to open them to the public someday). Still, you can peek inside them since their bases are not solid (the hollow structures are held aloft by a zigzag of beams.) The tower at the site entrance was completely empty inside save for a lone port-a-potty. The $440 million monster was designed to withstand a massive earthquake and even a direct hit from a jet airliner. The plant sat abandoned for until Ron Sauro, an entrepreneurial scientist decided to turn the facility into a world-class acoustical laboratory. Researchers now use the facility to test the sound absorbency of different materials.
