AbstractAbstract
[en] Ammonium diuranate U2O7(NH4)2 containing about 50% of water is dried and transformed by calcination in uranium trioxide UO3. Drying and calcination was obtained by air heated by two burners using domestic fuel. In 1984 the plant was transformed for utilization of electric heating improving maintenance cost, decreasing heat losses and by energy saving the payback period on investment is of 2.6 years

Le diuranate d'ammonium U207(NH4)2, contenant environ 50% de son poids d'eau est seche dans un presecheur a tablier, puis transforme en trioxyde d'uranium (UO3) dans un calcinateur a bande perforee. Le sechage calcination etait assure par de l'air chauffe au moyen de 2 bruleurs a fioul domestique. L'installation electrique mise en service en 1984 a permis d'ameliorer les couts d'entretien, de diminuer les pertes de chaleur et d'economiser l'energie, le temps de retour des investissements est de 2,6 anneesOriginal Title

AbstractAbstract
[en] Thermal shock behavior of UO2 pellets has been investigated by means of out-of-pile experiments and a theoretical analysis which particularly emphasized the porosity effect on the thermal shock damage. In the experiments, specimens of porosity range 0.05-0.15 were thermal-shocked by heating and then quenching in a water bath at various quenching temperature differences (ΔT). Results showed that with increasing porosity, ΔT values cause a first damage (ΔTsub(c)) and bring about destructive failure of the specimens increased, while the strength loss at ΔTsub(c) was reduced. These findings suggested that the higher the porosity, the higher the pellet integrity during rise to power. Theoretical equations expressing the thermal shock damage were introduced. Good agreements were obtained between observed and predicted values. (orig.)

AbstractAbstract
[en] The NUKEM price range jumped sharply last month, ending up at $8.05-$8.70. The market took off amidst reports that price and volume quotas would be part of the antidumping settlement being negotiated by certain CIS republics and the US Department of Commerce. And the republics got no relief from the US Court of International Trade. In an opinion issues September 25, Judge Jane Restani upheld the validity of Commerce's investigation, reinforcing the rising trend in prices. The lower end of the range was established by offers of CIS origin uranium to those utilities that will not be affected by Euratom or Commerce restrictions. Ten deals were completed on the spot market in September. In all but one, the sellers were intermediaries
