According to Conner, various structures such as warehouses,
reactors, reactor fuel manufacturing facilities and an enormous
cooling tower no longer stand at SRS.
Built in the 1950s, the P and R Reactor buildings were mammoth
structures both above and below the ground. In 2011, they were
decommissioned, using a unique process that filled the structure
to ground level with a specially designed concrete-like grout. This
cleanup work locked contamination inside the buildings and avoided
the cost of continuing interior maintenance.
