Y -- Safe Storage Enclosure (SSE) Roof Construction - 105-D Reactor

The construction of the roof over the SSE (with a design life of up to 75 years) will occur during the final stages of the project to construct the SSE. Most radiological contamination will have been fixed or removed in underlying areas where the roof is to be constructed. A new roof will be designed and constructed over the SSE that will conceptually consist of structual steel columns, beams, girts and purlins with pre-formed standing seam steel roofing. Open areas between the roof and the top of the reactor shield wall (gable ends and eaves) will be closed with similar sheet steel roofing material. The roof structure will be anchored to the top of the reactor shield walls. All remaining SSE penetrations will be sealed. The final SSE roof structure design and calculations will be part of the subcontract for engineering, design, and construction of the SSE. This subcontract will be set-aside for award to small business firms only. The estimated subcontract value is between $1.8 and $2.5 million. The subcontract performance period (award through design and completion of SSE roof construction) will be approximately 18 months.
