[cdn-nucl-l] AECL annular fuel
High-Performance Fuel Design for Next Generation PWRs (Annular Fuel Project)
AECL successfully loaded two four foot lengths of annular fuel using the
VIPAC approach, achieving a maximum density of 77% of theoretical. This is
insufficient to meet the reference fuel loading requirements, which require
an effective uranium oxide density of at least 85% of theoretical UO2
Part of this task is to design the fuel irradiation experiment and develop a
fuel performance model. MIT researchers completed manufacturing and testing
of all the components for the in-core test. Two of the VIPAC annular fuel
samples manufactured by AECL were instrumented with thermocouples and
assembled into irradiation capsules.
Question: how does the water get into & out of the internal cooling
passageway ? ....at the ends only, or also at ports along the length of the
full-scale PWR fuel pins ?
