As a result of the damage caused by the March 11, 2011 earthquake & tsunami to Tokyo Electric Power Company’s (TEPCO) Fukushima Daiichi nuclear power plant, plant operators used seawater to cool the reactors. The process, used to remove the resulting radioactive contaminants, requires pumping seawater through a series of pressure vessels, each containing proprietary media designed to filter the radioactive elements. Working under an emergency contract, Eaton procured steel from around the U.S., provided engineering services & fabricated (100) of these vessels. The vessels are composed of a total of (400) cylindrical shielding jackets, each having a combined thickness of (7) inches and an OD of just under (5) ft.. The contract was completed in just over (5) weeks.
