New Cono Seals Shielding

NPO’s new Cono Seals shield package exemplifies another unique and ideal application for T–Flex®. The Cono Seals are a significant dose contributor during reactor head disassembly and, most recently, reactor head cavitation peening in PWR’s. NPO used Tungsten T–Flex to achieve a HVL (half value layer) of shielding from Co–60. Simple Velcro straps are used […]

NPO uses MCNP to simulate Dry Cask

Dry Cask processing operations present a number of complex radiological challenges. The presence of both neutron and gamma radiation coupled with the varying amounts of shielding already provided by the cask and canister make it difficult to know where to put shielding and what type shielding to use. Additionally, shielding limitations often exist in the […]
