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.

The 235U content of a spent MTR fuel element enclosed in a lead transfer cask has been nondestructively measured by observing the delayed-neutron emissions following high energy neutron induced fission. Fourteen MeV neutrons from a (D,T) neutron generator moderated through 8 in. of lead were used as the interrogating radiation. A DTF-IV calculation was used to correct the data for the contributions due to other fissionable isotopes. The nondestructive measurement agreed to within 1.5% with the 235U content as predicted by reactor burnup calculations.
