Prototype experiment of an irradiation facility for large HTR fuel specimens in the HFR Petten. Project E 91 - 0
Description
A prototype irradiation facility for the in-pile examination of full-size fuel compacts or other larger HTR fuel specimens by the vented operation principle has been tested in the HFR Petten during about 239 full power days, in which the in-pile as well as the out-pile equipment demonstrated a very good reliability and a safe operation. The specified irradiation conditions could be maintained throughout the testing period. Visual inspection of the rig components and also the fissile specimens after dismantling showed good conditions of all parts. The fissile specimens achieved a maximum fast neutron fluence of up to 5.86x1021cm2(E0.1MeV) and a maximum burn-up of up to 8% FIMA at a maximum fission rate of about 2.4x1014 fissions per sec. The irradiation temperature was in the range of 10500C
