Abstract
This report describes the work performed, data obtained and visual observations made during the first examination of high burnup fuel bundles as part of a joint United States Department of Energy (DOE), General Electric Company (GE), Northern States Power company (NSP) BWR Fuel Bundle Extended Burnup Program. Four 8 x 8 reload fuel bundles which had been operating at the Monticello Nuclear Generating Plant since the beginning of cycle 3 had each attained an average burnup of 33,800 MWd/MTU. Three of the fuel bundles were examined during the reactor refueling outage at the end of cycle 7. The fourth bundle was discharged and examined after the refueling outage, including the removal of three spacers, the water rod and twelve fuel rods for subsequent hot cell examination.
