Project Experience

EnergySolutions has successfully delivered many innovative projects.


ZionSolutions is a subsidiary of EnergySolutions responsible for decommissioning the Zion Nuclear Power Station in Zion, Illinois 45 miles north of Chicago on the shores of Lake Michigan. The goal of the project is to safely transfer the spent fuel onsite to a highly technically engineered storage pad. Once the fuel is safely removed deconstruction of the power plant will begin. Proprietary, proven technologies and process will be utilized to ensure worker and public safety during all decommissioning activities. Upon completion of the decommissioning project the property and NRC license will be returned to Exelon.

Advanced Mixed Waste Treatment Project (AMWTP), Idaho National Laboratory (INL), Idaho

Retrieval, sorting, characterization, and shipping of 120,000 cubic meters of contact-handled transuranic (TRU) and Low-Level Mixed Waste from INL to the Waste Isolation Pilot Plant (WIPP) in New Mexico.

This state-of-the-art facility was designed, built, commissioned and put into operation in just 46 months, with hot operations commencing in August 2004. AMWTP utilizes remote handling techniques and waste characterization operations all performed while maintaining very high integrity containment of the waste. A box assay system provides criticality control of retrieved boxes prior to receipt at the AMWTP Facility. Remotely-operated technologies size-reduce crated waste; fill and assay 55-gallon drums prior to super-compaction; and fill 100-gallon puck drums. The 2,000-ton-force supercompactor and attendant glovebox suite is one of the largest installations of its type for nuclear waste handling.

Salt Waste Processing Facility (SWPF), Savannah River Site (SRS) in South Carolina

Separation of high-level waste into highly active and low active fractions so the former can be vitrified and the latter cement grouted in existing SRS facilities.

There are 37 million gallons of high-level waste-containing some 426 million curies of radioactivity-stored in 49 tanks at the Savannah River Site (SRS). It requires the separation of cesium, strontium and TRU from the rest of the waste. The SWPF achieves this with a combination of solid absorption and filtration plus solvent extraction. E&T produced a Phase 1 conceptual design for a treatment facility with process capacity of 3.75 million gallons per year. We are currently working on Phase 2, which is final design, construction, commissioning, and initial hot operation. E&T personnel are providing nuclear design, technology, and operations/commissioning expertise to the integrated project team at an office based in Aiken, South Carolina.

Hanford Shipping Facility Conceptual Design

Shipping of high-level waste glass product logs from the Waste Treatment Plant (WTP) to the HL Waste repository.

EnergySolutions produced a conceptual design for this first-of-a-kind facility. Our operational research model provided real-time throughput analysis and optimization and compared shipping and storage options. We provided proven cask and canister handling techniques by adapting designs already in use in the UK, and developed multiple layouts and optional site locations for canister receipt.

Hanford K Basin Sludge Retrieval, Transfer and Stabilization

Retrieval, stabilization, and packaging of spent nuclear fuel sludge.

EnergySolutions designed the three-pronged system that will retrieve, transfer to treatment, and package for disposal, nuclear fuel sludge that has accumulated in the Hanford K Basins for several decades. Our vacuum lances and customized nozzles and pumps move the material into consolidation containers within the basins. Special attention had to be paid to the heat generation and potential criticality issues with the irradiated uranium-containing sludge. A system of pumps and flexible, transportable hose-in-hose piping system will re-mobilize the sludge and pump it to the treatment facility, also designed by E&T, where the sludge will undergo dewatering and accelerated oxidation of the uranium in order to limit the hydrogen-generating capability of the final waste-form. Additional systems measure and control the fissile content and place the waste-form in a cement-grout inert matrix for final disposal.

Service Highlight

EnergySolutions designed NUEXTM, an efficient, three-cycle reprocessing system using proven solvent extraction technology and equipment, and making use, where appropriate, of UREX unit processes developed by the US National Laboratories. This system is substantially proven at an industrial scale in the UK and is capable of immediate industrial realization in the US, with relatively small development and confirmatory testing. Its design is flexible so that extra unit processes can be added as and when they are proven and the need for them is confirmed.
