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 […]

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 […]

Pressurizer Spray Line Shielding

  South Texas Project required new shielding for a section of the pressurizer spray line. Though the area looks small, the total shield weight was around 850 lb (386 kg). This was due to the 6.5″ (165 mm) diameter of the pipe and the 1.5″ (38 mm) thick shielding pieces. But despite the size and […]

T-Flex Blankets

How many lead wool blankets does your site deploy every outage? Despite best efforts, do your lead blankets look sloppy while draped over pipes and hot spots or seem mashed and bent around corners and tight spaces? How long have they been there?  How are they handling the use and abuse? Lead wool blankets, while […]

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 […]
