AbstractAbstract
[en] This paper briefly describes the present situation in the field of plutonium fuel production and explains concepts used by Belgonucleaire to develop technology and production processes for application by the mid-1980s. Of particular interest is the COGEPEL process developed by the company, which consists of pelletizing gelified mixed-oxide microspheres. The introduction of the new process should improve the overall safety of the plutonium industry. 5 refs

Ces études couvrent Les domaines de la neutronique et du transfert de chaleur. Sur le plan de la neutronique théorique, on décrit brièvement les travaux d'adaptation et d'étalonnage des codes de calcul pour les réseaux PuO2 - UO2 - H2O. On expose ensuite le programme expérimental en cours depuis juin 1967 dans l'installation des essais critiques VENUS du CEN avec des combustibles plutonifères de caractéristiques diverses.Original Title

Proceedings of joint topical meeting on commercial nuclear fuel technology today
Proceedings of joint topical meeting on commercial nuclear fuel technology today
AbstractAbstract
[en] After more than one year operation of the Belgonucleaire Pu Fuel Production Plant at Dessel, Belgium, the authors outline their conclusions regarding the cost of Pu recycling in water cooled reactors. The paper analyses the Pu recycling cost penalty in 3 specific cases. An analysis of the Pu value is also given for the three cases. It is concluded that the Pu fuel production penalty varies according to the three referenced cases from 180 to 70 percent of the total cost of U235 enriched fuel and that the corresponding Pu value varies from 6 to 11 dollars per g Pusub(f) on the basis of 15 dollars per lb U3O8 and enrichment at 42.1 dollars per SWU.

AbstractAbstract
[en] The paper describes and compares the available head end techniques for production of pelletized mixed oxide fuel. It discusses the solubility of PuO2 in nitric acid as well as its radioactivity, both of which influence the choice of the head end process. The paper also describes several ways to convert the mixed plutonium-uranium nitrates from fuel reprocessing into mixed oxides, and proposes a SOL-GEL-type process as a preferred way. (orig.)

Die Abhandlung beschreibt und vergleicht die verfuegbaren Kopf-Ende-Techniken zur Herstellung von gemischten Oxid-Brennstoffen in Pellet-Form. Sie diskutiert die Loesbarkeit von PuO2 in Salpetersaeure sowie ihre Radioaktivitaet, von denen beide die Wahl des Kopf-Ende-Verfahrens beeinflussen. Die Abhandlung beschreibt auch einige Methoden zur Umwandlung von gemischten Plutonium-Uran-Nitraten aus der Brennstoff-Wiederaufbereitung in gemischte Oxide, und schlaegt ein Sol-Gel-Verfahren als bevorzugte Methode vor.

AbstractAbstract
[en] Mixed oxide nuclear fuel is now commercially well established. The engineering infrastructure is ready to cope with current demand and is taking steps to widen the applications of MOX fuel by, for example, increasing burnup. The DEMOX plant has more than come up to expectations, and the European MOX industry is ready to expand capacity if demand continues to grow. (author)

AbstractAbstract
[en] The advantages of plutonium recycling in thermal reactors are described. The quantities of plutonium available during the next decade (1970-80) will probably exceed the requirements of the first prototype fast reactors and the first power stations equipped with such reactors. Within the European Community, plutonium recycling on a commercial basis could begin during the first years of the next decade, using those thermal reactors that are most suitable for the operation. With a view to predicting which reactors will be the most suitable, the relationship between the characteristics of such reactors and the possibility of plutonium enrichment is analysed. In particular the effects of neutron spectrum, plutonium enrichment, fuel heterogeneity and fuel management are considered. The conclusions of this analysis are compared with those of studies so far available concerning the value of using plutonium in different types of thermal reactor. This comparison suggests that pressurized-water and high-temperature gas-cooled reactors will be the most suitable for burning plutonium. Finally, the authors consider what effect plutonium enrichment in these two reactor types can have on the various factors making up their fuel cycle costs. The technical data on recycling available at present allows us to conclude that the recycling constitutes an economic proposition. (author)

Le mémoire décrit l'intérêt du recyclage du plutonium dans les réacteurs thermiques. La masse de plutonium qui sera disponible durant la prochaine décennie (1970-1980) sera vraisemblablement supérieure aux besoins des premiers prototypes de réacteurs rapides et des premières centrales de puissance équipées de tels réacteurs. Les premiers recyclages de plutonium pourraient de ce fait être réalisés dans la Communauté européenne, sur des bases commerciales, dés les premières années de la prochaine décennie, dans les réacteurs thermiques le mieux adaptés à cet usage. En vue de prévoir quels seront ces réacteurs, le mémoire analyse l'influence des caractéristiques de ces derniers sur leur éventuel enrichissement en plutonium. Il examine notamment l'effet du spectre neutronique, de l'enrichissement au plutonium, de l'hétérogénéité du combustible ainsi que de la gestion du combustible. Il juxtapose les conclusions de cette analyse à celles qui découlent des études réalisées à ce jour en vue de définir la valeur d'usage du plutonium dans les différents réacteurs thermiques. Cet examen laisse entrevoir que les réacteurs de type PWR et à gaz à haute température semblent les mieux appropriés à brûler le plutonium. Le mémoire examine enfin l'influence que peut avoir un enrichissement en plutonium de ces deux derniers types de réacteurs sur les différents paramètres intervenant dans le coût de leur cycle de combustible. Les données techniques sur le recyclage acquises à ce jour permettent de conclure qu'il constitue une opération valable sur le plan économique. (author)Original Title
