Fanhouse Demolition Completed
The reactor Fan House, Building 704, was a one-story, above-grade structure approximately 168 feet long by 60 feet wide. The concrete block building was initially constructed to provide primary and secondary cooling air for the Brookhaven Graphite Research Reactor (BGRR). It enclosed the BGRR discharge plenum and also housed the electrial switchgear and the normal and emergency power batteries for the High Flux Beam Reactor (HFBR). The switchgear provided normal power to Buildings 703 and 701, and also provided the pathway for the HFBR exhaust through underground ductwork and filter banks (removed in 2003).
Demolition of the 704 Fan House was completed in 2010 as one of the near-term HFBR ancillary projects completed early with ARRA funding.
