AbstractAbstract
[en] The attention and needs of the fuel-pin designer and licenser have focussed on the middle ground between steady-state and accident testing on fuel pins and subassemblies. In the US this middle ground has come to be known as Operational Reliability Testing (ORT). It relates to the off-normal conditions that may be anticipated to occur sometime during the operating life of a commercial reactor. At EBR-II such testing involves pins that have already failed (run-beyond-cladding-breach testing); pins that experience mild-overpower or duty-cycle transients during irradiation (operational-transient testing); and the more general areas of the thermal-hydraulic testing of naturally-distorted clusters of pins under both normal and natural-convection modes of cooling (shutdown-heat-removal testing). This paper updates the status of the preparations and capabilities described in previous publications for operational reliability testing at EBR-II up to the present time when the ORT program is about to begin.
