Stochastic simulation of destruction processes in self-irradiated materials [PDF]
Self-irradiation damages resulting from fission processes are common phenomena observed in nuclear fuel containing (NFC) materials. Numerous α-decays lead to local structure transformations in NFC materials.

3D continuum percolation approach and its application to lava-like fuel-containing materials behaviour forecast [PDF]
The paper is devoted to the theoretical study of elementary permeable objects percolation and its application to real physical objects. Spheres and isotropic oriented capped sticks were chosen as elementary geometrical objects for percolation simulation,

Reactor criticals and spent fuel systems similarities
Many conservative assumptions for subcriticality assessment calculations have to be made in current calculations of spent fuel storage systems. This is due to a fact that there is no available database of benchmarks containing spent fuel or materials ...
