Decontamination Support Testing Removal of subsurface Contamination | BNFL, Inc. Oakridge, TN
Under the reindustrialization program at the DOE’s former weapons production complex at the K-25 site in Oakridge, TN, EAI was selected to perform testing to demonstrate our ability to decontaminate porous materials that were contaminated with radioactive isotopes such as technetium, plutonium, and uranium. The concrete surfaces of the buildings not only had loose surface contamination but also contained high levels of deeply embedded subsurface contamination. To eliminate extensive labor to scabble and jackhammer the concrete and to reduce the amount of buried waste that would be created during clean up of the buildings, EAI was contracted to perform a technology demonstration using a chemical extraction technology to decontaminate both concrete and metallic surfaces. The chemistry is applied topically to the surface of the material in a three-step sequence. The formulas utilize a complex matrix of both high and low pH solutions to open the pores and migration pathways of the substrate, seek out and encapsulate the target contaminants breaking the electrostatic and chemical bonds and then extract the contaminant using floatation chemistry.
EAI demonstrated the removal of contamination at levels up to 2,000,000 dpm/100cm2 to less than background in one application of the process.
Decontamination, De-Sludge and Lockdown of Tank Farm | DEMCO, Inc. Connecticut Yankee D&D Project
Under subcontract with DEMCO, Inc. EAI was tasked to de-sludge, decontaminate and apply lockdown fixatives on all eight of the plant process tanks including the ADHUT, RWST, RTT’s, BWST’s and WTT’s.

Under contract with Kaiser Hill Company, who is the managing contractor for the US Department of Energy at Rocky Flats, EAI provided decontamination services and technical support to decontaminate plutonium contaminated glove boxes and process equipment to reduce them from TRU waste to SCO I and II levels for disposal. EAI provided site wide support for all buildings involved in this phase of the D&D project. Significant savings have been achieved through reductions in disposal costs, as well as, acceleration of the project schedule.
Reactor Head Support Work | Bechtel Power Corporation Connecticut Yankee D&D Project
EAI was contracted to remotely apply a lock down fixative to all surfaces of the reactor head in order to prepare it for final shipment to the burial site as part of the site decommissioning activities. Prior to EAI applying the lock down, Bechtel cut the thermal sleeves and nozzles away from the underside of the reactor head and allowed them to fall to the floor inside the reactor head stand. Following the lock down work and the removal of the reactor head from containment, EAI was contracted to utilize a specially designed robot with manipulator grip arm to retrieve the thermal sleeves and nozzles and remotely place them onto an engineered pin rack for placement into an 8120 shipping cask for disposal. The thermal sleeves had extremely high radiation dose rates and were highly contaminated with alpha contamination as well as beta gamma contamination. The use of the robot to retrieve the thermal sleeves significantly reduced radiation exposures for the project.
Decontamination for Final Survey | Maine Yankee Atomic Power Co. Maine Yankee D&D Project
EAI has been awarded the contract for the Maine Yankee D&D project to remove paint and concrete from all of the interior surfaces of the PAB and Spray buildings at the Maine Yankee site. The work was performed in preparation for final site survey for the decommissioning of the former nuclear power plant. EAI is utilizing a new technology know as concrete shaving to accomplish the removal. EAI mobilized to the site in December 2001 and completed the majority of the work by September 2002. The concrete shaving technology achieved all of the clients established goals for the project related to engineering controls for dust free removal of the concrete, smooth surface finish for final survey accuracy and minimization of waste. In addition, EAI has been providing demolition support for the removal of trenches, concrete pump pads, sump liners, embedded metals and hot spots in the concrete in order to meet the site Derived Concentration Guideline Levels (DCGLs) for the license termination plan. Recently EAI completed the decontamination of the containment trenches and sumps along with the containment safeguard cross over piping systems.
Decontamination Support for Decommissioning | Shaw Environmental and Infrastructure, Inc. Gulf Nuclear D&D Project
EAI supported Shaw Environmental under their Rapid Response Contract with the US Army Corps of Engineers for the decontamination of components and building surfaces of a former radioactive source manufacturing facility. The buildings contain gloveboxes and air handling systems that are contaminated with high levels of Class C radioactive material for which there are limited commercial disposal options. The goal of the project is to decontaminate the components to Class A waste so that they can be disposed of as low level and to assist with the clean up of the buildings for demolition. EAI deployed a team of decon specialists that used our chemical extraction technology to complete the decontamination and waste reduction activities. In addition, EAI performed the removal of the components from the building and packaged the waste for final disposal. As part of our service, EAI also furnished support equipment, portable HEPA ventilation systems and a mobile decontamination trailer based unit to handle the clean up of the site. Once the facility was abandoned by the former company that ran the source manufacturing business the project had been prioritized under the Homeland Security Act to mitigate the risk of radioactive materials falling into the wrong hands and being used to produce “Dirty Bombs”.
Shaw Environmental & Infrastructure, Inc. | Los Alamos National Laboratory
EAI recently completed testing of our Chemical Extraction technology at Los Alamos in Building TA-55 under a Large Scale Demonstration and Deployment project for the DOE. The TA-55 Building is being converted to a new mission and requires extensive decontamination of gloveboxes and components that were used to support past years of work for the nuclear weapons program. The original plan called for the removal, size reduction and disposal of these components as TRU waste and complete replacement of the equipment for the new mission.
EAI’s technology has shown that these components can be effectively decontaminated to levels low enough to be converted to reuse rather than being replaced. This represents a significant cost savings to the DOE and the lab. Baseline estimates show that the use of EAI’s process will save hundreds of thousands of dollars per glovebox. As part of the test, Los Alamos tested other processes against EAI’s chemical extraction technology and EAI’s process was the clear winner.
Additional work using this new strategy began in early 2013 wherein EAI is supported the processing of the legacy waste at the site.
Fluor Hanford Company | Hanford DOE Site
EAI was awarded the contract to provide our chemical extraction technology and on site technical support for the decontamination of plutonium contaminated glove boxes at both the Plutonium Finishing Plant (PFP) and the 232-Z Incinerator Facility. The objective of the project was to decontaminate all glove boxes and components from high level TRU waste down to low-level waste under the SCO criteria for on site disposal. The project is expected to be complete in approximately 27 months.
Energy Solutions | Los Alamos National Laboratory
The TRU legacy waste created from decades of weapons production had been stored above ground at area G for many years. When the wildfire occurred near the site, concerns were raised about the security of the waste and plans were instituted to process over 3700 cubic meters of waste and have it removed from site. EAI, under contract to Energy Solutions provided our Rad-Release technology and technical support personnel to process glove boxes, tanks and other materials and successfully decontaminated 100% of the waste from TRU to low level. The schedule acceleration, elimination of size reduction and cost avoidance from not requiring disposal of this material at WIPP resulted in huge savings to the program.
Naval Surface Warfare Center | EAI Western Operations Santee CA
At the time of the Fukushima Nuclear Plant accident in Japan, many surface ships from the US Navy were stationed in the region. During this time, many of the Navy assets became contaminated as a result. EAI has established a radioactive licensed facility in Santee CA to support the receipt, survey, disassembly, decontamination and release of these assets for return to the Navy as clean for re-use.
PCB decontamination of facilities was previously accomplished using solvent-based cleaners to remove surface contaminants. A typical PCB-contaminated site cleanup normally requires two solvent wipe downs to free release the facility. EAI recently expanded operations to include PCB cleanup actions. The following project summaries describe EAI’s experience in this area.
PCB Decontamination Services | Confidential Client
EAI provided PCB decontamination services to a demolition contractor responsible for the cleanup of a contaminated 1600 square-foot facility. The facility was located on a jet-fuel chemical manufacturing site in New Jersey. EAI provided a PCB decontamination plan, equipment and services, and operator/worker training.
PCB/Furan Decontamination and site remediation | Harding Lawson Associates Winslow, ME
In conjunction with the closure of a former mill and sale transfer of the property, EAI was contracted to utilize our technologies to remediate certain areas of the plant where PCBs and Furan contamination existed from a past transformer fire. The State of Maine DEP and the EPA mandated cleanliness criteria that had to be met in order for the sale transfer to go through and to allow reindustrialization and future use of the structure. EAI successfully decontaminated the building surfaces to below the mandated clean-up protocol. In addition to the surface cleaning activities, EAI was also contracted to perform selective demolition, which included complete removal of the concrete floor in the load center where the fire occurred. The project was completed on schedule and within budget. Prior to commencing work, EAI was tasked with writing a work plan and procedures to assist the clients in gaining approval from the regulatory agencies. EAI also provided our own health and safety oversight during the evolutions involving site work and managed the packaging of contaminated waste.
PCB/Lead Paint Removal | Confidential Client
Faced with extremely high disposal costs and very conservative environmental regulations, EAI was contacted to develop a solution for a large-scale decommissioning project. EAI spent several months developing a proprietary process to successfully remove PCB and lead containing paints from porous concrete, formed concrete, and a variety of metallic substrates. Onsite testing and a technology demonstration was conducted for the client in the actual field D&D setting on PCB and lead contaminated materials. Following the test, samples were obtained to verify the effectiveness of EAI’s process. The test was termed a “complete technical success” by the client. Additional work scopes and site strategies are being developed on how EAI’s approach can benefit upcoming evolutions on the project.
Historical Restoration | Town of Exeter, NH
EAI was contracted to assist in the restoration and renovation of the Exeter Town Hall building, which is a very significant historical monument in New England. EAI’s scope of work was to contain the structure and remove all of the paint from the ornate wooden portions of the cupola and front portico of the structure. Multiple layers of paint were removed down to the bare wood to allow reconstruction and new paint to be applied to complete the restoration.
Lead Paint Removal/Environmental Action Program | Confidential Client
As a part of a site wide environmental action program at a large electrical utility company, EAI has been contracted to provide environmental cleaning services to eliminate lead paint hazards from components at their various sites. Environmental audit deficiencies have prompted the need to enact a utility wide program to remove old lead containing paint from components and structures at the utility’s substations. EAI was awarded the work based on our experience and knowledge in handling and remediation of the lead hazards as well as our ability to manage the industrial hygiene and safety aspects of the project. EAI’s technology was selected due to the fact that no secondary wastes are generated and no damage is caused to the equipment being abated. To date, EAI has allowed the utility to correct audit findings and reduce health risks to their employees working at the substations.
In general, industries such as manufacturing and food processing use Freon and trichloroethane as cleaning and degreasing agents in a wide variety of applications, including final cleaning of produced products and cleaning of production-line machinery. One of the technologies that EAI offers, C02 blast cleaning, can be substituted with superior results. EAI’s Industrial Cleaning Team specializes in supporting shutdown and outage projects for a range of applications. Cleaning has been completed on several different types of boilers, oven (food and blast) interiors, conveyor belts, and components. In all cases, C02 blast cleaning proved to be a viable alternative to water blasting, sand blasting, PMB (bead blasting), and solvent cleanings for the removal of general surface grime, plastics, urethanes, weld splatter, flux, carbon deposits, and other materials. The following project serves as an example of our experience providing these services.
Blast Cleaning Testing and Process Development | Xerox
As part of an ongoing effort to eliminate harmful solvents in the workplace, EAI was contracted to perform testing and process development for specific Xerox remanufacturing applications. After process and nozzle development, the testing proved that C02 blast cleaning can serve as a replacement for solvent cleaning, achieving higher levels of cleanliness than solvent methods and reducing cleaning time by up to 50 percent. The materials cleaned ranged from molded aluminum parts and steel castings to optics and wire harnesses. The design and installation of a facility-wide blast cleaning system is underway.
Condenser/Heat Exchanger Cleaning | Lewcott Corporation
The client was in the process of adding new resin and polymer manufacturing capabilities to their production facility. During the plant upgrade and retrofit several older condensers and heat exchangers (that had been out of service for several years) were installed to support the new production plant. Upon inspection, it was determined that the tube-side of the components were plugged with old residues and required cleaning prior to start-up. EAI was contracted to provide both mechanical services and cleaning services to refurbish the equipment. EAI personnel removed the heads, cleaned the tube sheets and the internals of the tube bundles using specialized tooling to cut out the built up residue, brush clean and polish the tube I.D., install new gaskets and reassemble the heads onto the condensers and ready them for service.
General Industrial Applications
EAI provides high pressure water blasting, all types of abrasive blast cleaning processes using walnut shell, corn cob, sodium bicarbonate, plastic bead, glass bead, black beauty, aluminum oxide, magnesium oxide, AIM, steel shot, furnace slag, and liquid abrasives, as well as scabbling, shot blasting and chemical extraction. Projects include surface preparation for recoating or for non-destructive examination, process line and facility cleaning, fire restoration, and other industrial cleaning needs. EAI constantly supports the power generation, automotive, petrochemical, food service, and mass transit industries with our mobile fleet of equipment.
Tank Cleaning | GAF Materials Corporation
Manufacturing complexes that utilize large tanks to hold process materials prior to induction into the manufacturing of finished products require industrial cleaning contractors who can provide a variety of technologies or methods to support process changeovers and annual maintenance shutdowns. GAF contracts EAI to provide our high-pressure water blasting process to remove up to 21” of process residues from three large tanks, followed by grit blasting to allow annual inspections and NDE testing to be performed. EAI provides project supervision, labor, confined space monitoring and permitting, as well as safety oversight to complete the work turnkey.
Fossil Power Plant Services | Various Clients
EAI continues to support the power generation industry year-round to keep plants operating at peak efficiency. As a result of the burning of various fossil fuels, plant systems and components can become fouled, thus affecting the heat rate and power output of the plant. EAI furnishes turnkey industrial services to clean boilers, economizers, heat recovery steam generators (HRSG’s), selective catalytic reduction (SCR) walls, ammonium injection systems and turbines. Our field services and industrial operations personnel are available to support planned outages, as well as, unscheduled emergency shutdowns. EAI’s cleaning systems and technologies are mobile trailer based units that can be dispatched anywhere in the world to support onsite cleaning requirements of large fixed facility plant equipment.
Freon and trichloroethane are used widely to remove grease, oil, and other contaminants from surfaces that require absolute cleanliness (e.g., satellites and Titan IV rocket payload fairings), as well as in the manufacturing and remanufacturing processes. The sale of most chlorofluorocarbons (CFC’s) has been banned for use on U.S. Air Force contracts (effective July 15, 1992). Chemical agents, acid and alkali solutions, and blasting media all leave measurable amounts of residues and have high disposal costs.
As an example of EAI’s C02 blast cleaning capabilities, at Martin Marietta, Titan IV rocket payload fairings were formerly cleaned by technicians using cotton swabs and Freon – the total task requiring 18,000 to 24,000 labor hours. EAI accomplished the same task using a robotic C02 blast cleaning system in only 46 labor hours, a time reduction of 99.74 percent. The acceptable surface contaminant level was 1.0 mg/ft2 for non-volatile residue (NVR). The previous method, Freon cleaning, achieved results at and slightly below this level. After C02 blast cleaning was demonstrated, the results were consistently 0.2 to 0.3 mg/ft2 NVR, a three to four-time reduction in levels.
Past EAI projects in the aerospace field include the following (selected samples):
