CLEAN SMART bill reintroduced in Senate
Senators Ben Ray Luján (D., N.M.) and Tim Scott (R., S.C.) have reintroduced legislation aimed at leveraging the best available science and technology at U.S. national laboratories to support the cleanup of legacy nuclear waste.
The Combining Laboratory Expertise to Accelerate Novel Solutions for Minimizing Accumulated Radioactive Toxins (CLEAN SMART) Act, introduced on February 11, would authorize up to $58 million annually to develop, demonstrate, and deploy innovative technologies, targeting reduced costs and safer, faster remediation of sites from the Manhattan Project and Cold War.

Plutonium-238 in contaminated trash and equipment contained in steel drums was determined by measuring, with a Nal(Tl) detector, the intensity of the 765-keV gamma ray from the decay of 238Pu. By gamma-ray stripping, the contributions of higher energy gamma rays to the 76S-keV gamma-ray photoelectric peak could be subtracted, despite the large amount of scattering material present in the drum. The transmission of the 765-keV gamma ray inside the drum was determined by measuring the transmission through the drum of the 765-keV gamma ray from external 238Pu standard sources. The uncertainty in the measurements is ±28% at the 95% confidence level when the drum contains ≥0.180 g of 238Pu.
