Barrnon has successfully demonstrated and delivered its latest Bladecutter System – the Small Riser Residuals Pump (SRRP) – to the client at Hanford.
The SRRP represents the smallest iteration yet of Barrnon’s proven Bladecutter sludge recovery technology, developed over a two-year project to support retrieval of waste from Hanford’s underground storage tanks.
Engineered to fit through a 4-inch riser, the SRRP combines a compact sludge-cutting and pumping system capable of removing waste from depths of up to 70 feet. Using Barrnon’s Bladecutter technology, which has no mechanical moving parts in contact with the waste stream, the system offers a robust and low-maintenance alternative to traditional pumping methods.
Extensive testing using Hanford tank simulants confirmed the SRRP’s ability to collect 7–20 kg of solids per minute, drawing down sludge to less than an inch while maintaining efficiency and reliability.
This milestone delivery marks another significant step in Barrnon’s mission to provide innovative, safe, and cost-effective waste retrieval solutions for the nuclear sector.
