The evaluation of the thermal behaviour of an underground repository of the spent nuclear fuel
The paper concerns the evaluation of the thermal behaviour of an underground repository of the spent nuclear fuel. The problems are solved by the in-house GEM-FEM finite element software. A parallel solution of the arising linear systems by the conju...
