The synergetic interplay between the removal of saturated methyl esters and the addition of deoxygenated fatty acids on depressing the cloud point temperature of biodiesel was investigated in this study. Canola biodiesel was produced in batch as a standard with a cloud point of 1.37 +/- 6.3°C. Saturated methyl esters...
Fuel loading patterns which have a minimum power peak are
economically desirable to allow power reactors to operate at the highest
possible power density and to minimize the possibility of fuel
failure. A computer code called SHUFLE was developed for pressurized
water reactors which shuffles the fuel in search of...
This report presents a refined method for the calculation of fuel centerline temperatures and the linear-heat-rating-to-incipient melting, ' Q'[subscript m], of mixed-oxide fuel typical of that to be used in the Fast Flux Test Facility and in Liquid Metal Fast Breeder Reactors. Of primary concern are the effects of the...
Large digital computer reactor fuel performance codes
perform repeated calculations of temperature profiles
during transients. The thermal response is required to
calculate the mechanical behavior. This mechanical
response in turn feeds back to the thermal calculations
through mechanisms such as fuel swelling or shrinking,
causing changes in the fuel-clad gap...
The establishment of any thermal model of reactor fuel
requires a thorough understanding of the behavior of the
thermal conductivity. This is especially true in the case
of sphere pac fuels where the conductivity is a function
of many variables beyond those normally affecting conventional
fuels. One of these variables,...
Hydrazine based fuels are used by the Air Force for the Titan II
and Minuteman III missiles and the F-16 aircraft and by the National
Aeronautics and Space Administration for propulsion systems and the
Space Shuttle Program. These uses represent significant production,
transportation and storage of these fuels, and, as...
The use of advanced concepts can make the nuclear fuel
cycle more efficient by allowing pins to be operated at
high powers and to higher burnups. Among the more
promising concepts in advanced fuels is sphere pac fuel.
In a first attempt to bring together models describing
individual phenomena, the...
