  1. 26. Convergence improvement and qualification of a model for fission gas behaviour in nuclear fuel

    University essay from KTH/Numerisk analys, NA

    Author : Gaël Dubus; [2007]
    Keywords : modelling; nuclear; fuel; PWR; numerical; solver; convergence; qualification;

    Abstract : During the irradiation in a fuel assembly of a Pressurized Water Reactor (PWR), the thermal diffusion processes are not the only active mechanisms: the effects of irradiation are significant, involving variations of the diffusion coefficients as well as creation and evolution of point defects and cavities in the material.In this document we present the work we have done on MOGADOR, a numerical fission gas behaviour model for nuclear fuel under irradiation in a PWR focusing on the modelling of the behaviour of irradiation defects, fission gases and as-fabricated pores.

  4. 28. Does the design of the shelter influence the levels of behavioural stress and aggression in group-housed male guinea pigs?

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Angelica Nordlund; [2004]
    Keywords : Guinea pig; shelter; behaviour; stress; aggression;

    Abstract : For animals, such as the guinea pig, which are obtained from breeders, it is of legal as well as of scientific concern that the animals have an acclimatization period just after arriving at their new animal facility. During this period, the guinea pigs have a chance to decrease the levels of stress, caused by the process of moving. READ MORE

  5. 29. Exploration of submarine fans along the Coffee Soil Fault in the Danish Central Graben

    University essay from Lunds universitet/Geologiska institutionen

    Author : Jakob Magnusson; [1999]
    Keywords : seismic; Early Cretaceous; Late Jurassic; Danish Central Graben; submarine fans; Earth and Environmental Sciences;

    Abstract : On the footwall side of the Coffee Soil Fault in the Danish Central Graben, five potential petroleum reservoir structures were distinguished on seismic images. The deposits were formed during the Late Jurassic-Early Cretaceous transition. READ MORE
