The present invention relates to a modular nuclear fuel element, which can be adapted by an assembly system allowing it to be used in different nuclear power plants with horizontal and vertical cooling channels. The module is a cluster of parallel fuel rods mounted as circular concentric crowns and supported by a structural system. It has a single diameter fuel rod array where the ratio of the heat transfer area to the transverse rod area is higher than 330. It also has self-supporting fuel element spacer grids, which are collapsible sheaths attached to them with fewer than 13 welded end stoppers. 2, record 2, English, - fuel%20element%20spacer%20grid

L'industrie papetière est une industrie qui consomme beaucoup d'énergie. L'accroissement de la vitesse des machines à papier, la sophistication des systèmes de traitement des papiers récupérés et le perfectionnement technologique en général se sont traduits par une hausse de la consommation d'électricité dans les papeteries alors que la consommation de vapeur restait pratiquement inchangée. On peut réduire les pertes d'énergie dues à sa génération et à la production de chaleur en combinant la génération des deux, chaleur et électricité (CHP ou cogénération). [...] Dans l'industrie papetière, les besoins en énergie et le rapport chaleur-énergie sont parfaitement adaptés à la technique de la cogénération [...] 2, record 3, French, - rapport%20chaleur%2Dforce

The ratio of the energy content of the fuel used to the electrical energy produced over a given period; it can be referred to the electricity generated(gross) or the electricity supplied(net). The reciprocal of the heat rate expressed as a percentage is the thermal efficiency of the power station. In the case of the "heat rate" the units should be stated; in the case of the "thermal efficiency" the energy content of the fuel and the electrical energy produced must be expressed in the same unit. 4, record 4, English, - heat%20rate

Record number: 5, Textual support number: 2 OBS
In respect of a boiler, "heat output" relates to the energy value of the useful hot water or steam produced. In considering electricity generation, however, the overall thermal efficiency is the total energy value of the electricity "sent out", expressed as a percentage of the energy value (gross as fired) of the fuel used. This overall concept takes account of both boiler and steam turbine losses. A modern power station achieves about 35 per cent thermal efficiency. 4, record 5, English, - thermal%20efficiency

Le perfectionnement des RHTRG [réacteurs à haute température refroidis par gaz] aura pour but d'améliorer la performance et de prolonger la durée de vie des centrales. Pour le premier point, de nombreuses recherches sont actuellement consacrées à ce que l'on appelle le cycle à turbine à gaz, où un gaz à haute température alimente directement une turbine à gaz ce qui permet d'obtenir un rendement thermique très élevé et un coût de l'énergie très intéressant ainsi qu'à la production de chaleur industrielle à très haute température. 2, record 5, French, - rendement%20thermique
