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 […]

Magnetic ARGOS Booth Shielding

Byron had an issue with an ARGOS Zeus unit in the main exit area of the RCA. Background gamma radiation from a line in the overhead was shining down and causing false alarms on the gamma detectors to the point of making the unit inoperable. Due to the position of the Argos unit it was […]

Boiler Plate Shields

Inside the steam generators of CANDU nuclear power plants, a divider plate separates the hot leg from the cold leg. Dozens of bolts hold this divider plate together, and these bolts trap hot particles that are a major source of radiation during inspections. NPO designed magnetic shielding designed to fit around each bolt. Since it […]

Saint-Alban Steam Generator Shielding

EDF Saint-Alban plant, located in Saint-Maurice-l’Exil, France, collaborated with NPO Europe to address a few opportunities for shielding the steam generators during sludge lancing operations. Saint-Alban wanted to reduce shielding installation and removal time from the benchmark of 5.5 hours, reduce total project dose from 476 mRem (4,760 μSv), and remove the physical clutter of […]

Bio-Shield Door Shielding

Limerick Generating Station was in need of custom shielding for their bio-shield doors. Even though shielding was already installed, there was still a gap that continued to be a source of dose. NPO worked closely with ALARA Specialist, Joe Bruno, at Limerick to design a 4-piece magnetic set of custom lead blankets. Each piece had […]
