Benchmark Experiments in Water-Moderated Fully-Reflected 6.90% Enriched UO 2 Fuel Rod Lattices with a Fuel-to-Water Volume Ratio of 0.52 [Slides]

A second set of experiments in the Seven Percent Critical Experiment (7uPCX) has been completed. Additionally, an evaluation of the experiments as criticality safety benchmark experiments has been performed. The Reviews of the benchmark evaluation have been completed. This evaluation will be published in the 2013 edition of the International Handbook of Evaluated Criticality Benchmark Experiments as LEU-COMP-THERM-078 (LCT078). This presentation is a brief tour of these experiments.

Modeling of Fission Gas Behavior in Uranium Oxide Nuclear Fuel Applied to Engineering Fuel Performance Codes

This presentation provides an update on the I-NERI project 2017-004-E between INL and JRC-Karlsruhe (European Commission). I-NERI is a collaboration initiative between the European institutions and the US DOE which favors collaborative work. INL is involved in multiple INERI projects, principally on the experimental side but also on the modeling side with this project, which focuses on fission gas modeling. This year's I-NERI meeting is in the USA (LLNL) and G. Pastore, who is the US PI for this, will provide the update. The project has led to fission gas developments that are being applied in the Bison code and strengthened collaborations of INL in this area with JRC and POLIMI.

Integral U/TRU recovery cathode system for electrorefining used nuclear fuel, method for electrorefining and harvesting metal from used nuclear fuel

The invention provides a system for collecting metal in an electrorefining process, the system having a hollow cathode; and a container defining an upwardly extending surface adapted to be received by the hollow cathode. An embodiment of the invention provides for metal reduction to occur on laterally facing and medially facing surfaces of the cathode such that electrolyte resides between surfaces of the cathode. Also provided is a metal electrorefining process having the steps of subjecting molten salt containing metal moieties to electrolysis wherein reduced metal accumulates in a cathode-cup construct in a first position; raising the construct to a second position above the molten salt while subjecting the construct to heat from the molten salt; withdrawing the cathode from the construct into a vestibule to the electrorefiner to a third position; and removing the cathode and cup from the electrorefiner to a fourth position.
