Lean-burn is an attractive concept for reasons of high thermal efficiency and low nitrogen oxide (NOx) emissions, however, successful implementation in spark-ignition (SI) engines turned out to be challenging because misfire or partial burn caused by attenuated flame propagation. In order overcome this issue, microwave-assisted plasma ignition system (MAPIS) has been applied combustion systems....

Following Taiwan's nuclear waste management policy, INER launched first Independent Spent Fuel Storage Installation (ISFSI) project in 2005. The technology of dry storage system adopted is NAC-UMS system. made some design modifications order to accommodate the constraints at Chin-Shan Nuclear Power Plant (CSNPP). modified UMS was named as High Performance System (INER-HPS). corresponding Safety...

Improved understanding of how fuel loads and prescribed fire interact in Appalachian hordwood forests can help managers evaluate the impacts of inueased use of prescribed fire in the region. The objective of this study was to characterize fuelloods before and aher a single late-winter/early spring prescribed fire and aher autumn leaf fall. A repeated measures split-plot design was used to exami...

The expansion of piñon-juniper woodlands the past 100 years in the western United States has resulted in large scale efforts to kill trees and recover sagebrush steppe rangelands. It is important to evaluate vegetation recovery following woodland control to develop best management practices. In this study, we compared two fuel reduction treatments and a cut-and-leave (CUT) treatment used to con...

Abstract—Analysis of the uncertainty quantification related to nuclear safety margins applied to the nuclear reactor is an important concept to prevent future radioactive accidents. The nuclear fuel performance code may involve the tolerance level determined by traditional deterministic models producing acceptable results at burn cycles under 62 GWd/MTU. The behavior of nuclear fuel can simulat...

The possibility of using antihydrogen for igniting inertial confinement fusion pellets or triggering large scale thermonuclear explosions is investigated. The number of antiproton annihilations required to start a thermonuclear burn wave in either D or Li2DT is found to be about 10/k, where k is the compression factor of the fuel to be ignited. We conclude that the financial and energy investme...

Fuel after inflaming burns at high (till 15-20 МПа and more) pressure, thus is formed gaseous combustion products with temperature 3000-4500 K, which effuse to the ambient space through the nozzle. On length of the nozzle the temperature and pressure of them decrease, and the velocity increases, passing through a sound velocity in minimum (critical) cross-section of the nozzle and reaching 2700...
