Title X of the Energy Policy Act of 1992 authorized U.S. Department of Energy (DOE) to reimburse licensees of 1 thorium and 13 uranium processing sites (see map above) for a portion of their remedial action costs attributable to the sale of source material to the federal government.

The amount eligible for reimbursement is determined by applying a Federal Reimbursement Ratio which is based on the amount of source material sold to the federal government.

Under the Title X Program, DOE receives claims from U.S. Nuclear Regulatory Commission (NRC) or Agreement State licensees annually, conducts technical reviews and financial audits of the claims to determine the amount allowable for reimbursement, reimburses each licensee, and tracks amount paid, disallowed, and owed in a running ledger.
