Nuclear reactor design with refuel period of more than 20 years
It's not so simple and straightforward. One has to maintain criticality and an appropriate power distribution, which may be accomplished by burnable absorbers and/or control rods, as well as margins to technical limits. One cannot avoid the accumulation of fission products from the fission...- Astronuc
