The Swedish Nuclear Fuel and Waste Management Company (SKB) has chosen a site for permanent storage of highly adioactive spent fuel from Swedish plants. The site, near Forsmark, is 75 kilometers north of Stockholm. Estimated to cost between $2.5 billion and $3.2 billion, the repository includes 50 km of tunnels in granite bedrock 500 meters underground, requiring the excavation of 1.8 million cu m of rock. Spent fuel would reside in 25-tonne copper-coated canisters, surrounded by a buffer of bentonite clay that would act as a watertight barrier. SKB plans to submit two applications to Swedish environmental and nuclear authorities
The market is generally healthy and steadily growing, and margins are up for large specialty contractors. Further, advances in design tools and owner demand for collaboration are giving subcontractors a seat at the table early on in projects.
