As part of its annual audit plan, the OIG audited $16.7 million in costs billed to the Tennessee Valley Authority (TVA) by EnergySolutions, LLC (ES) under Contract No. 69836. The contract provided for ES to furnish personnel, equipment, chemicals, and consumables necessary to process liquid radioactive waste for all three TVA nuclear operating sites. Our objective was to determine if the costs billed to TVA were in accordance with the provisions of TVA's Contract No. 69836 with ES. In summary, we determined ES overbilled TVA $85,246, including: (1) $42,229 in ineligible and unsupported supply, per diem, and travel costs for spent fuel pool cleanout work; (2)$28,967 in ineligible equipment costs; (3) $11,500 in unauthorized waste shipments; and (4) $2,500 in ineligible dewatering and cask costs. ES agreed the ineligible equipment costs were overbilled and issued a credit to TVA on January 14, 2015. In addition, we found $68,898 in costs paid under Contract No. 69836 that should have been paid under Contract No. 69885. We recommended TVA management take action to (1) recover the remaining $56,279 in overbilled costs from ES and (2) ensure future costs paid to ES are paid under the correct contract.(Summary Only)
