Lead Slowing-Down Spectroscopy (LSDS) is a candidate for non-destructive assay of spent nuclear fuel (SNF) [4]. Research was collaborated via the Material Protection, Accounting, and Control Technology (MPACT) campaign under the Department of Energy. Researchers include: Pacific Northwest National Laboratory (PNNL), Los Alamos National Laboratory (LANL), University of Nevada Las Vegas (UNLV), R...
A 20-year-old male aircraft mechanic presented to our clinic with a chief complaint of hearing loss 1 day after getting sprayed with JP-8 (jet propulsion fuel). The patient reported fuel spraying on his face and ears while taking samples from an aircraft. He reported a persistent burning sensation to his face, lasting approximately 8 hours, followed by a left-sided hearing loss. The patient als...
Stable power processes are never guaranteed. An assortment of unstable behaviors wrecks power apparatus, including mechanical vibration, malfunctioning control apparatus, unstable fluid flow, unstable boiling of liquids, or combinations thereof. A necessary condition for stable reactor power is that the reactor distortion accompanying a temperature rise decreases the reactivity, thus slowing an...
A procedure for estimating fuel burned based on actual flight track data, and drag and fuel-flow models is described. The procedure consists of estimating aircraft and wind states, lift, drag and thrust. Fuel-flow for jet aircraft is determined in terms of thrust, true airspeed and altitude as prescribed by the Base of Aircraft Data fuel-flow model. This paper provides a theoretical foundation ...
The neutron-induced fission cross-section of Am has been measured relative to the standard fission cross-section of U between 0.5 and 20MeV. The experiment was performed at the CERN n TOF facility. Fission fragments were detected by a fast ionization chamber by discriminating against the αparticles from the high radioactivity of the samples. The high instantaneous neutron flux and the low backg...
To run a high conversion reactor with Pu-Th fuelled tight fuelled assembly, which has a long burn-up of a fuel, the reactor should be sited deep underground. By putting the reactor deep underground heat can be removed passively not only during a steady-state run and also in an emergency case of loss of coolant and loss of on-site power; hence the safety of the reactor can be much improved. Also...
