Abstract: The walltickness of tubes in High Temperature Plants must be limited in such a way that pressure differences can not procedure unadmissible deformations. For HTR (PNP-Plant) the postulated loss of secondary pressure is one of the considered accidents. In that case the tubes of the heat exchangers are loaded by the outer pressure of the primary coolant. So the risk of a creep collapse is given.The report is related to experimental and theoretical work for the creep collapse phenomena. HTR relevant tube geometries of the high temperature alloys NiCr22Co12Mo and XIONiCrAlTi 32 20 were tested at temperatures of 900 and 950°C and outer pressure loads in the range 40 bars. The experimental results are compared with theoretically computed values and discussed. The problem of safety margin is treated. Further, simplified procedures are developed for the estimation of the collapse time.
