House, Senate bills aim to improve nuclear decommissioning and waste disposal
Two bills were introduced in the last several weeks aiming to address nuclear power at the end of life—decommissioning plants and recycling used fuel.

The space-dependent kinetics of a strongly coupled multiregion cylindrical reactor were studied both theoretically and experimentally. A three-node model was used to calculate the kinetic response in the various regions and these results were compared with two-detector noise measurements. Reasonable agreement was obtained for predicted and measured transfer functions, power spectral densities, coherence functions, and alpha, the ratio of the effective delayed neutron fraction to the prompt neutron lifetime. Differences in the kinetic response of the various regions were clearly evident.
