Microbiologically facilitated corrosion in closed cooling systems has become more of a concern due to the nature of pitting corrosion cells protected by slimes and cemented crusts. While biocides may effectively control the overall bacterial counts, the protected environments provide a setting for localized corrosive and electrochemical attack.

The chemical decontamination process was developed for commercial use in the late 1970s and early 1980s and has been used by Westinghouse for more than 30 years.

Westinghouse offers innovative solutions to meet customer’s decontamination and effluent waste treatment needs. Westinghouse addressed these needs by developing a variety of chemical decontamination processes and delivery systems. Westinghouse has four different, off-the-shelf, field ready systems that target a specific size system to ensure an efficient and effective decontamination.

Nuclear facilities that are no longer operating due to economic factors, licensing issues, end-of-life components or other reasons are candidates for decommissioning and dismantling (D&D), followed by site restoration.

Westinghouse has designed, fabricated and installed a full-system decontamination modular system at an operating nuclear power plant and performed a 105,000-gallon, in-situ chemical decontamination of the pressurized water reactor, steam generators and plant cooling systems.

Westinghouse has provided quality products and services to the nuclear industry for more than a decade. Using this experience, and incorporating unique concepts, it has developed a high-flow backwashable filtration system that can process at high flow rates and at filter sizes to the sub-micron range. These systems provide a cost-effective way to meet diverse filtration demands.

Nuclear utilities have a need to decontaminate hot spots and small systems/components at a reasonable price. Westinghouse is addressing this need by developing a variety of chemical decontamination processes and delivery systems. In addition to Westinghouse’s standard system decontamination and full-system decontamination, its lineup of decontamination equipment/services now includes:

Chemical decontamination is routinely performed to remove activated corrosion products from boiling water reactor (BWR) plant piping while simultaneously reducing plant dose rates. This process was developed for commercial use in the early 1980s, and has since been successfully applied by Westinghouse to more than 300 BWR system decontaminations.
