The Hazard from Plutonium Dispersal by Nuclear-warhead Acciden
Nuclear weapons are carefully designed to have an extremely low probability of exploding accidentally with an appreciable yield—even if they are involved in a high-speed crash, struck by a bullet or consumed in a fire. The principal concern when nuclear warheads are involved in such accidents is the possible dispersal of plutonium into the environment. In particular, an explosion could disperse...
متن کاملDetermination of the internal exposure hazard from plutonium work in an open front hood.
The particle size and quantity of a plutonium dioxide surrogate escaping an open front hood during routine work was measured. Aerosols were collected using a cascade impactor, and the amount of surrogate on each stage of the impactor was measured using neutron activation analysis. The aerodynamic mass median diameter of particles in the breathing zone of a worker was found to be 0.35 ± 5.1 μm. ...
متن کاملHazard Assessment for Pressure Tank Cars involved in Accidents
In the event of an accident or derailment involving a freight train, various personnel must respond to clear the rightof-way, repair the tracks, and remove the damaged rail cars. If the train contains pressure tank cars, the potential hazard needs to be assessed and safe handling procedures need to be followed. Since 1985, the Association of American Railroads, Transportation Technology Center ...
متن کاملNa-Tech accidents induced by floods: an approach to hazard and risk assessment
Several accidental events that occurred in chemical and process plants in the last decades evidenced that floods may cause severe damages to process plants and storage sites, resulting in multiple and extended releases of hazardous substances. Moreover, besides conventional release scenarios (fires, explosions and toxic clouds), floods may cause two further critical events: significant environm...
متن کاملHydride-Catalyzed Corrosion of Plutonium by Air: Initiation by Plutonium Monoxide Monohydride
Chemistry and kinetics of air reactions with plutonium monoxide monohydride (PuOH) and with mixtures of the oxide hydride and plutonium metal are defined by results of pressure-volumetemperature (PVT) measurements. Tests with specimens prepared by total and partial corrosion of plutonium in 0.05 M sodium chloride solution show that reaction of residual water continues to generate H, after liqui...
