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:
Intermediate System – For ISD services, the targets include small plant systems and parts of larger systems with volumes of up to 1,000 gallons. This system is ideal for decontamination of pipes, letdown lines, small systems and components such as heat exchangers. Individual components of the ISD consist of a pump skid, a chemical mix tank with in-line heater and ion exchange columns. A flow reversal skid is also employed, where necessary, to provide optimum flow characteristics. This equipment is accompanied with the required one-inch and two-inch hoses and process instrumentation.
The ISD is shipped in one or two Sea-Land® containers (one truck) depending on project requirements, such as hoses and shielding. The equipment is set up by an engineer and technician, and an engineer and technician perform continuous (per shift) operations. The equipment consists of individual components arranged to suit customer site conditions.
Westinghouse customers benefit from this ISD skid in the following ways:
Westinghouse has nearly 30 years of experience supporting nuclear power plants with chemical decontamination services. Its variety of processes and now its variety of system sizes allows Westinghouse to meet specific customer needs. Westinghouse has performed hundreds of chemical decontaminations from small components to full-system decontamination.
