Thermoelastic tensions in the coating a coated particle after introducing a fresh one Fuel element ball into the core of the ''PR 500''

Automatic translation: When introducing fresh fuel elements into the core of the PR 500, the coated particles heat up immediately. While in A previous work [1] investigated whether during the heating process not permitted within the spheroidal graphite during heating If high thermal voltages occur, it is examined here whether unacceptably high temperatures occur in the coating of the coated particle during heating. It also became apparent here that the greatest tensions occur in the stationary state. The greatest tensile stress is around 7000 times smaller than the breaking stress.
