The project consisted of the construction of a new nuclear spent fuel storage facility, a Heavy Hauler Transport Facility (HHTF) building, the associated monitoring, security lighting, camera towers, and a new Maintenance Muster Facility (MMF) building to support future outage work. In order to accomplish the task within a very small footprint, phased demolition of several existing structures and a hydrogen bulk storage facility was performed in parallel. All facilities were constructed inside the secure protected area.
Preliminary excavation with hydro-vac equipment was used to uncover charted underground utilities and identify uncharted utilities. Several existing underground utilities were relocated to avoid interferences with the new foundations. New electrical, communications, data, water, and fire protection services were installed to the new buildings and storage pad as required.
The MMF is a 100’ x 85’ pre-engineered steel building with facilities for the muster of the large temporary workforce. The building includes offices, conference rooms, bathrooms, and an eating/break area. The HVAC systems provide ventilation when heavy equipment is in the building, and the building is fully covered by a fire suppression sprinkler system.
The HHTF is a 80’ x 50’ pre-engineered building designed to house the heavy haul transport equipment required for fuel transfer and storage. The heated building has large metal hatches in the roof, storage and maintenance areas, and is protected by a fire suppression sprinkler system.
Over 4,000 cubic yards of concrete was pumped under the protected area fence to complete the approximately 260’ x 270’ storage pad.
