National Park Service sign unveiled in the first Y-12 building constructed during the Manhattan Project


A ceremony was held at the Y-12 National Security Complex to unveil the sign for Building 9731, which is part of the NPS Manhattan Project National Historic Park.

OAK RIDGE, Tenn. – Officials gathered at the Y-12 National Security Complex Wednesday for a special ceremony marking a historic building.

Building 9731, the first building constructed at Y-12 in 1943, during the Manhattan Project of World War II, served as a pilot plant for nine facilities used to separate enriched uranium. This uranium would then be used in the atomic bombs dropped on Japan towards the end of the war.

A National Park Service sign was unveiled on Wednesday, marking the building’s historical significance. It is part of the NPS Manhattan Project National Historic Park.

“It’s great to see the collaboration that went into creating these new signs and to know that the signs will enrich visitors’ understanding of Building 9731 and the important role it played during the Manhattan Project,” said Peter O ‘Konski, Deputy Director of the Office of Legacy Management.

Building 9731 will be used in the future as a training facility for Y-12 employees, echoing one of its main roles during the Manhattan Project. It is also renovated to better train employees, while retaining its historic character.

“It will come full circle from the pilot plant, once again serving as a training facility while telling the stories of those who came before us,” said Bill Tindal, chief operating officer of Consolidated Nuclear Security, LLC, l manager and operator of Y-12. .
