Millstone Hot Spot Shielding

In 2025, Millstone Power Station faced a persistent dose rate challenge at a 45° elbow hot spot, where dose rates exceeded 20 Rem/hr. The existing temporary solution—shielding blankets wrapped around the pipe—was both visually unappealing and insufficient attenuation. Positioned overhead, the source posed unnecessary exposure to personnel working in the area. To address the issue, […]

Frisker Caves

NPO designs and manufactures a variety of frisker caves to reduce handheld Geiger Mueller (G-M) tube counters background radiation. The four featured designs range from heavy duty, maximum dose reduction caves to lighter and more mobile caves. T-Flex Variable Thickness Frisker Cave This frisker cave allows you to add and adjust the shielding thickness as […]

Rad Shipping Containers

NPO and Eichrom teamed up to launch a Rad Shipping System product for the radiopharmaceutical industry.  We worked closely with PET shipping experts to develop something that meets this industry’s unique needs.  Our emphasis was on durability, optimized shielding, hygienic, minimized footprint, ergonomic, and smooth operation.  Today our systems are used throughout the US. 10-30 […]

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