“The product is just what we wanted.”
Corey F, Sr. Radiological Engineer
“The molded shielding was extremely fast, simple, and easy to install. My shielding team members were elated for how fast they were able to install this shielding. Thank you, NPO, this is a fantastic product.”
Romalis DALARA Planning
“The shielding NPO made us for the Pressurizer Spray Line went perfect.”
Martin HALARA Planning
“We officially completed the Incore Sump Room Shielding project on nightshift on 4/29/23. There were ZERO safety or human performance issues during this implementation. The team came in under the 96-hour installation window and ~300 nRem under the dose allocation! Thank you to the ENTIRE NPO team for making this s HUGE success!!”
Sheri LProject Leader
“Everyone is very satisfied with the shielding that your company provided for the 360-inspection platform. It is already in-use.”
Rick SHealth Physicist

Custom Radiation Shielding Applications

Oconee Heat Exchanger Skid Shielding

BEFORE AFTER Oconee Nuclear Station contacted NPO to develop a permanent shielding solution for the Supplemental Spent Fuel Cooling Heat Exchanger. The heat exchanger is located inside the truck bay with one side exposed to the main truck bay door at the Radiologically Controlled Area (RCA) boundary. The ALARA planners at Oconee wanted a permanent […]

Browns Ferry 360-Inspection Platform

Browns Ferry needed durable and effective floor shielding for the trough of their 360 cavity inspection platform. Like with most floor shielding applications, T-Flex® Bismuth was chosen because of its great attenuation properties relative to its cost. On top of the Bismuth shielding was a yellow slip-resistant tread surface to ensure workers would be able […]

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. TEST NPO T-Flex Bismuth blankets are large […]

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’ (305 mm x 1829 mm) 60 lb (27.2 […]

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 […]
