Fuel casing

Preparation of Diesel Fuel - The same severely hydro-treated 250°F+ products from the three syncrudes described in the jet fuel case meet all specifications for No. ID fuel oil, as shown in Table VI. The cetane test is accurate to about two numbers. Probably all three hydrotreated syncrudes just meet the ASTM required minimum of 40. Conventional additives could be used to improve the cetane numbers, as shown by experimental results discussed elsewhere. ( 8)... 

The yield periods for the preparation of diesel fuel are shown in Table III. These yield periods are the same as shown above in the jet fuel case. Properties of diesel fuel cuts and naphthas are shown in Tables IV and V, respectively. 

The following will be dedicated to the emulsified fuel case, with a few words on how the arguments could be changed to accommodate them to the other situation. 

The validation calculations with MERIT indicated that KENO, used with Hansen and Roach cross sections, overpredicts the reactivity for the water-flooded fuel ease by <2% and underpredicts the dry fuel case by <1%. This is consistent with previous KENO validation calculations performed by General Electric in support of a fuel bundle shipment container license application. ... 

Cofiring woody biomass in coal-fired boilers is performed differently depending upon the type of boilCT in PC boilers, woody biomass is typically injected separately from the coal unless vray low percentages of woody materials are used (e.g., <5 percent by mass, or <2 percent by heat input). This separate injection is based upon adding flexibility to the boiler operations. Demonstrations have shown that separate injection permits concentrating the woody biomass in a single location to optimize NOx reduction. Additionally, separate injection facilitates recovery of boiler steaming capacity that can be lost when wet coal is received by the power plant. In cyclone boilers the woody biomass is typically blended with the coal and introduced into the boiler with the coal [20]. In order to evaluate these uses of woody biomass as an opportunity fuel, case studies are employed as described below.

Time-dependent dose rates were evaluated for the representative 3.2 wt% fuel case with cobalt as a seed. Dose rates were evaluated at 10% of design exposure (3.2 GWD/MTHM). Natural cobalt (100% Co) was included in the fuel at 0.1 wt% (1 kg Co per metric ton of initial heavy metal). The relative time-dependent dose rale contributions following shutdown are shown in Figure B-3. For the 0.1 wt% case, the Co do.se contribution is only slightly larger than that of the fission products at decay times between 2 and 10 years. For the 1 wt% case, the Co dose contribution exceeds that of the fission products for decay times between about 0.5 and 30 years.
