Fuel cycle cost of a fast reactor is expected to play an important role of compensating for higher capital cost of a Fast Reactor and keeping the unit energy cost competitive. PFBR fuel cycle cost has been worked out by a committee constituted for the purpose. The cost has been worked out for a peak fuel burn-up of 1,00,000 MWd/t. The basic components of the PFBR fuel cycle are fabrication cost...

An understanding of aircraft fuel burn and emissions is necessary to evaluate their effects on the environment. In this paper, data from Flight Data Recorders (FDRs) have been used to estimate the operational values of times in mode, fuel flow rates, fuel burn, NOx emission indices, and quantities of emissions produced during the Landing and Take Off (LTO) cycle for 12 aircraft-and-engine combi...

We present pre-burn biomass and consumption data from 60 prescribed burns in the southeastern and western United States. The datasets include pre-burn biomass in Mg/ha by fuel category: herbaceous fuels, shrubs, 1-hr, 10-hr, 100-hr, 1000-hr, 10,000-hr, and > 10,000-hr downed wood, litter and duff. Pre-burn depth (cm) and reduction (cm) are provided for litter and duff layers. Day-of-burn fuel m...

In order to analyze the effect of hydrogen rich gas addition (HRG) on lean burn engine’s thermal efficiency and emission, an experimental research was conducted on a gasoline direct injection (GDI) engine using definite fraction of HRG. The results showed that HRG addition could significantly extend the lean operation limit, improve the engine’s lean burn ability, and decrease burn duration. HR...

The taxi-out phase of a flight accounts for a significant fraction of total fuel burn for aircraft. In addition, surface fuel burn is also a major contributor to CO2 emissions in the vicinity of airports. It is therefore desirable to have accurate estimates of fuel consumption on the ground. This paper builds a model for estimation of on-ground fuel consumption of an aircraft, given its surface...
