The nuclear reactors involved in the 2011 crisis at Fukushima I in Japan were GE designs,[183] and the architectural designs were done by Ebasco,[184] formerly owned by GE. Concerns over the design and safety of these reactors were raised as early as 1972, but tsunami danger was not discussed at that time.[185] As of 2014[update], the same model nuclear power reactors designed by GE are operating in the US;[186] however, as of May 31, 2019, the controversial Pilgrim Nuclear Generating Station, in Plymouth, Massachusetts, has been shut down and is in the process of decommission.
