AbstractAbstract
[en] This is a brief conference paper on the use of biofuels in vehicles, especially in Sweden. Vegetable oils replace only diesel. In Sweden, the vegetable oil most often used is rape-seed oil. These oils are not very efficient in ''raw'' form and are used as basis in esters, such as rape-seed methyl ester (RME). Although RME is renewable, biobased and reduces the atmospheric CO2 emission, it increases the emission of nitrogen oxides, it may cause startup problems in cold weather and is not stable when stored for long. Most RME available in Sweden is imported and the potential for increased Swedish production is very limited. By using methanol and ethanol both petrol and diesel can be replaced. While mixtures of petrol and alcohols are being used increasingly, mixtures of diesel and alcohols are unstable and their use requires technological development

AbstractAbstract
[en] A review of the spent fuel management concepts generally adopted in several countries is presented, including an analysis of the brazilian situation. The alternatives are the reprocessing, the interim storage and the final disposal in a repository after appropriate conditioning. The commercial operating reprocessing facilities in the Western World are located in France and in the United Kingdom. In the USA the anti-reprocessing policy from 1977 changed in 1981, when the government supported the resumption of commercial reprocessing and designated the private sector as responsible for providing these services. Small scale facilities are operating in India, Italy, Japan and West Germany. Pilot plants for LWR fuel are being planned by Spain, Pakistan and Argentina. (Author)

Atualmente existem instalacoes comerciais em operacao na Franca e na Gra-Bretanha.

AbstractAbstract
[en] Spent fuel assemblies of relatively long cooling term are contained at a central portion of a spent fuel storage cask, and spent fuels of relatively short cooling term are contained at the periphery thereof. Alternatively, spent fuel assemblies of MOX fuel assemblies comprising a mixture of plutonium and uranium are contained in a central portion of the spent fuel cask, and spent fuel assemblies of uranium fuel assemblies made of uranium are contained at the periphery thereof. When spent fuel assemblies are stored in fuel storage racks of a fuel storage pool, the same method can be adopted. In this case, storage for the spent fuel assemblies of long cooling term is completed precedingly. Alternatively, storage for the spent fuel assemblies of the MOX fuels is completed precedingly. This can ensure critical safety while storing the spent fuel assemblies densely. (I.N.)

AbstractAbstract
[en] On occasion, during routine operation of the plant or handling of fuel assemblies, damage may occur to individual fuel rods within the assemblies of the core. Mechanical features of NPP Krsko fuel assemblies permit the repair of assemblies by replacement of the damaged fuel rods. Assembly repair could be economical, especially if the low burnup fuel is damaged. However, it has to be shown that the use of the reconstituted assemblies is safe for the operation of the plant. Usually, solid stainless steel rods are used as filler rods. These rods affect reactivity and local power peaking factors due to the redistribution of the power within the assembly. The most important nuclear parameters of the NPP Krsko fuel are examined: Local power peaking factors, Reactivity change, Moderator temperature coefficient, Doppler temperature coefficient, Boron worth, Control rod worth, where up to three filler rods per assembly are considered.

AbstractAbstract
[en] The patent provides a method of conditioning the fuel in a reactor core to a predetermined maximum power level of operation so that subsequent relatively rapid changes in power level below and up to the maximum level can be made with minimum risk of pellet-cladding interaction fuel rod failures. This and other objectives are accomplished by taking advantage of the discovery that reactor fuel can be conditioned for subsequent high power operating level changes by a method of systematically increasing the local power of the fuel in the high power range at or below a discovered critical rate. (J.R.)

AbstractAbstract
[en] Various types of compounds were tested with the aspects of decomposition and formation of residue in a CO2 or 7H2+93N2 atmosphere. The evaporation temperature range of each compound was determined from thermogravimetric curve. Decomposition of dicarbon amide, stearic acid, acrowax and zinc stearate was studied by thermogravimetry in CO2 or in 7H2+93N2 atmosphere. All compounds were decomposed in CO2 atmosphere at lower than 400 .deg. C, but the residue, ZnO remained for zinc stearate. ZnO did not decompose in CO2 atmosphere up to 1300 .deg. C, but reduced into Zn metal and disappeared in the temperature range of 600 .deg. C to 1200 .deg. C in 7H2+93N2 atmosphere. The effect of residue, which trapped in closed pores of sintered pellet, on the thermal stability was studied using the resintering test at 1700 .deg. C in 7H2+93N2 atmosphere. In the case of oxidative sintered pellet with admixing zinc stearate, the cavity formation accompanied with a density drop after resintering is due to the pressure of the Zn gases trapped in the isolated pores
