Extensive VCC and HSM Experience
NAES has constructed a total of 466 VCCs and HSMs at nine nuclear power plants ranging in size from 50 MW to 3,810 MW. Each VCC weighs approximately 110 tons and takes three days to build. Each HSM is a thick, reinforced concrete structure about the size of a single car garage with the capacity to hold nuclear spent fuel bundles. All projects have been completed ahead of schedule and under budget while maintaining compliance with stringent client and Nuclear Regulatory Commission (NRC) regulations. Manufacturers include UMS, Magnastor, MPC, and UMH.
