Custom Radiation Shielding Applications

Radiography Shielding

Radiography is a non-destructive testing (NDT) technique that uses a radioactive source to detect flaws or defects in the internal structures, typically pipes. This testing process requires an “exclusion zone” to keep workers safe, and the use of shielding shrinks that exclusion zone and improves safety and efficiency. NPO T-Flex Bismuth blankets are large and […]

Custom Fit Meter Shielding

Some shielding applications require a precise fit in order to shield effectively. The meter of this instrument was a streaming source for the workers operating it. To fit the area, NPO used drawings of the steel housing and designed T-Flex Tungsten shielding that fit snuggly around the meter. 3D printed molds were used to create […]

Vogtle Reactor Head Shielding

In 2021, Vogtle reached out to NPO to help develop a new shielding package for around the reactor head. Their current system consisted of two rings: one under the head, and one around the outside of the head. Each of these shield rings used 1’ x 6’ 60 lb lead wool blankets. These shielding systems […]

Oconee Reactor Head T-Flex Shielding

Reactor head shielding is an essential part of every refuel outage. Oconee Nuclear Station sought to upgrade the shielding used at the bottom of the reactor head, opting to use lead-free T-Flex Bismuth blankets. Specifically designed for the application, these blankets T-Flex blankets were covered in blue PVC with Oconee specified printing that clearly indicated […]

Brunswick Permanent Valve Shield Box

Brunswick Nuclear Station had a valve that was causing a room to be a locked high radiation area. They wished to implement a permanent shielding package in order to down post the room. The valve was set to be removed during an upcoming outage. The Radiation Protection team reached out to NPO for a solution. […]

Primary Sample Panel Shielding

South Texas Project had long used lead wool blankets to shield their Primary Sample Panel, an area of the site within Chemistry that sees a lot of traffic. These lead wool blankets were affixed to the Primary Sample Panel via independent high strength magnets that attached to the grommets. With the blankets turned on their […]
