What are the specific features? Why nuclear waste is so important? Because the number of relevant interacting phenomena is high and, therefore, the system of equations are quite complex, because so many things happen at the same time.
Again there is a very little transference in real actions, because you are looking for, not for couples of years, but then thousand of years. And therefore the final design concept that we established with a high degree of confidence.
The long design life of the disposal schemes in tens of thousands of years and is well beyond other projects in conventional engineering and we cannot afford to make mistakes, and therefore the simulation is quite important.
The main source of radioactive waste is the production of electrical energy in nuclear power stations.
