Conference Article: Irradiation creep performance of graphite relevant for pebble bed HTRs
Kleist, G.; O'Connor, M.F. (Kernforschungsanlage Juelich G.m.b.H. (Germany, F.R.))Abstract
Irradiation - induced creep in the core reflector component graphite of high temperature reactors is of primary importance to the core designer since it provides a mechanism for the relief of internal stresses arising from differential Wigner shrinkage and thermal expansion. The experimental determination of the extent of this creep for conditions relevant to the reactor is thus imperative.
