EREF is a planned nuclear fuel enrichment facility that will be located in Idaho and will supply low-enriched uranium for use in commercial nuclear power plants in the US.

This project has received a $2bn conditional commitment for a loan guarantee from the US Department of Energy.

As per the terms of the contract, URS will perform its work in two phases.

During the phase one, URS will provide construction and procurement planning services while during phase two, URS will provide a full range of procurement, construction and management services.

The phase two will only commence upon AES receiving a combined operating license for the facility from the US Nuclear Regulatory Commission (NRC) and other necessary approvals.

The facility is expected to start operations in 2014 and to be fully constructed by 2017.
