The Guy at the Controls: Labor Quality and Power Plant Efficiency [PDF]

open access: yes
This paper examines the impact of individual human operators on the fuel efficiency of power plants. Although electricity generation is a fuel and capital intensive enterprise, anecdotal evidence, interviews, and empirical analysis support the hypothesis

Challenging Fuel Cycle Modeling Assumptions: Facility and Time Step Discretization Effects [PDF]

open access: yesarXiv, 2016
Due to the diversity of fuel cycle simulator modeling assumptions, direct comparison and benchmarking can be difficult. In 2012 the Organisation for Economic Co-operation and Development completed a benchmark study that is perhaps the most complete published comparison performed.

Simultaneous Enhancement of Tritium Burn Efficiency and Fusion Power with Low-Tritium Spin-Polarized Fuel [PDF]

open access: yesarXiv
This study demonstrates that using spin-polarized deuterium-tritium (D-T) fuel with more deuterium than tritium can increase tritium burn efficiency (TBE) by at least an order of magnitude without compromising fusion power output, compared to unpolarized fuel.

Performance and emission characteristics of swirl-can combustors to near-stoichiometric fuel-air ratio [PDF]

open access: yes
Emissions and performance characteristics were determined for two full annular swirl-can combustors operated to near stoichiometric fuel-air ratio. Test condition variations were as follows: combustor inlet-air temperatures, 589, 756, 839, and 894 K ...
