The More Hall Annex was a nuclear research building on the campus of the University of Washington in Seattle, Washington. Built in 1961, it housed a small research reactor until June 30, 1988, operating at a peak of 100 kilowatts thermal (kWt), and was decommissioned in 2007. The building was designed in the Brutalist architectural style by UW faculty members, using reinforced concrete walls. Large windows overlooking the reactor room allowed observation from the outside, in an attempt to demonstrate the safety of nuclear energy. The building was added to the National Register of Historic Places in 2009, after a campaign led by an architecture student in response to a demolition proposal from the university. Despite a lawsuit from preservation groups and the City of Seattle, the university began demolition of the building in July 2016. It will be replaced by a new computer science building that is expected to open in 2019.
