Temporary Radiation Shielding

Temporary radiation shielding and permanent shielding are distinctions usually reserved for nuclear power plants.  Temporary shielding is authorized by the site for deployment during a fixed period.  It’s often installed at the start of a work activity or outage and removed after completion.

Temporary radiation shielding is employed in places that are not conducive to the permanent introduction of new materials or loads on equipment, for instance Dry Wells in BWR’s, Containment Buildings in PWR’s, and Reactor Compartments of Submarines.  It can significantly reduce a facility’s Cumulative Radiation Exposure (CRE) during maintenance or refueling outages.  Temporary radiation shielding is used in a variety of ways.  It can be hung from scaffolding in front of large radiological sources for applications such as boiler radiation shielding, reactors, pressurizers, and steam generator radiation shielding.  It can be placed on sources such as pipes, elbows, valves, and heat exchangers.  It can also be laid on the floor when sources are coming flow below as with refuel bridge or 360 platform shielding.  Magnetic Shielding can be directly applied to carbon steel surfaces.

Temporary radiation shielding should be easy to install and withstand numerous installation and removal cycles.  NPO offers many off-the-shelf temporary radiation shielding options including T-Flex Blankets, T-Flex Pipe Shields, T-Flex Ribbon Wrap, T-Flex Magnetic, T-Flex Floor Shielding, and Lead Blankets.  Each of these options can be custom engineered to suit unique applications.
