Stress calculations on the reflector block of the pebble bed reactor Part II: Comparative calculations for slotted block

Automatic translation: The full-block test calculations already described in Part I of this report were supplemented by a further calculation so that the comparison with a parallel calculation by the company Hochtemperatur-Reaktorbau (HRB, Mannheim) could be made on an improved basis. In addition, two finite element calculations were carried out and described to determine the stresses in reflector blocks with slots on the front side. The two calculations refer to different heights in the reactor core (66.5 cm and 133 cm), which represent different loading cases with regard to the temperature distribution and the neutron-induced strains.
