Bipartisan nuclear waste bill introduced in U.S. House
U.S. representatives Mike Levin (D., Calif.) and August Pfluger (R., Texas) have introduced the bipartisan Nuclear Waste Administration Act of 2024, which would establish an independent agency to manage the country’s nuclear waste.
In addition to establishing a new, single-purpose administration to manage the back end of the nuclear fuel cycle, the bill would direct a consent-based siting process for nuclear waste facilities and ensure reliable funding for managing nuclear waste by providing access to the Nuclear Waste Fund. According to Pfluger and Levin, the bill’s provisions are in line with recommendations from the Blue Ribbon Commission on America’s Nuclear Future.

Radiation monitoring during operation of CERN's high-energy accelerators in general, and the Large Hadron Collider and its experiments in particular, poses a major challenge due to the stray radiation fields, which are characterized by a complex particle composition and a wide range of energies. In order to monitor ambient doses around workplaces and inside the machine tunnel, high-pressure ionization chambers (so-called IG5) and air-filled ionization chambers under atmospheric pressure (PMI) will be used. Because of the complexity of the radiation field, standard gamma or neutron radiation sources are not applicable to accurately calibrate monitors used in such environments. Hence, the use of Monte Carlo simulation programs like FLUKA is indispensable to obtain an appropriate monitor calibration. Following this idea the response of the aforementioned monitors to mixed particle fields ranging from thermal energies to several giga-electron-volts was simulated. Because neutrons are the main contributor to total dose at many locations around the accelerators, dedicated neutron experiments were carried out at the Research Center for Nuclear Physics, Osaka University, utilizing quasi-monoenergetic beams of 250 and 392 MeV to benchmark the simulated detector responses. Good agreement was found at 392 MeV, whereas at 250 MeV the calculations predicted considerably higher readings of the detector than the ones observed experimentally.
