Experiments have been performed in the Process Development Pile (PDP) and the Subcritical Experiment (SE) at the Savannah River Laboratory (SRL) to investigate the physics behavior of burned-up fuel in the CANDU and similar heavy-water power reactors. These experiments used specially fabricated fuel assemblies containing plutonium and uranium in approximately the isotopic compositions expected for fuel irradiated to 5000 MWD/ton. Separate sets of fuel assemblies also varied the total plutonium content and the isotopic fraction of 240Pu. An irradiation test of in-core flux monitors is being made in one of the Savannah River Plant reactors to determine the life characteristics of a selection of flux detectors and of the mineral insulation used in their construction. Self-powered flux detectors are relatively new; therefore, confidence in their use hinges to a great extent on proven performance at large integrated exposures. The chief points of interest are 1) integrity of the conductors and sheath during life, 2) life of insulation, and 3) sensitivity. The higher flux density available at SRP (vis-à-vis Chalk River) will shorten the irradiation time for a given exposure and should also show whether or not any new high Intensity effects appear. Fabrication and installation of the detector rod in the reactor has been completed and testing Is In progress. There were no special tests In October. The data being collected will be reported in a separate topical report at the conclusion of the tests.
