Übersetzung für "Fuel pellets" in Deutsch

The sintered fuel pellets in the reactor are frequently inclined to post sintering.

In contrast, in the production of oxide fuel pellets, there occur a number of difficulties.

The fuel rods contain fuel pellets of ceramically sintered uranium oxide in a zirconium tube.

This is a handful of these uranium oxide fuel pellets.

Wood pellets fuel is a limitless and environment friendly fuel source.

These bags are designed for packaging of fuel pellets.

The main direction of our activity is the manufacture and sell fuel pellets from husk of sunflower seeds, fuel briquettes.

As a CO2-neutral, renewable fuel, wood pellets have by now become established on the market.

And the problem with a traditional nuclear power plant like this is, you've got these rods that are clad in zirconium, and inside them are uranium dioxide fuel pellets.

Solid fuels include wood (see wood fuel), charcoal, peat, coal, Hexamine fuel tablets, and pellets made from wood (see wood pellets), corn, wheat, rye and other grains.

For this purpose, it has been previously proposed that balls or spheres containing absorber material, which are smaller in size than the fuel element pellets, be stored in a container above the reactor and that they be permitted to fall onto the surface of the pebble bed when required.

The absorber balls or globules then dribble or trickle through the spaces between the fuel element pellets and distribute themselves in the fuel bed, so that the reactor is likewise shut down.

Ceramic nuclear fuel pellets 6, which consist substantially of (U/Pu)O2 mixed oxide are contained in the cladding tube.

Thereupon, the nuclear fuel pellets 6, including the pellets which were caked to the inside of the cladding tube 3 and were blasted off by the expansion in the muffle furance, are poured out of the cladding tube 3 by the force of gravity.

These nuclear fuel pellets 6 are mechanically comminuted in a ball mill into powder which has a grain size of less than 400 ?m.

The invention, therefore, is based on the problem of developing a process for the production of ceramic fuel pellets which contain the fission and/or fertile material in oxidic form, by heating corresponding crude pellets to a temperature below 2500° C., quickly transferring them into a steel die, impact compressing at a pressing pressure below 1000 MN/m2 within a few milliseconds, ejecting the pellets and cooling in which no segregation and deposition of vaporized oxide occurs in the furnace, and above all no shrinkage cracks in the inside of the tablets.

The presence of solid fuel both in the heat-treating zone and in the cooling zone will result in a "multi-stage combustion" because the cooling gas emerging from the pellet bed on the cooling zone will be heated in the layer of solid fuel on the pellets by the combustion of solid fuel and will then be heated further by the combustion of entrained solid fuel in the gas flowing to the heat-treating zone and finally as the gas flows through the layer of solid fuel on the surface of the bed in that zone.

In order to solve the work material problems created by the presses at high temperature and pressure, there has been proposed the manufacture of the fuel pellets according to a hot impact compression process (HSV process) (German Pat. No. 2842402 and related Hrovat U.S. Pat. No. 4,271,102).
