The Current Status on DUPIC Fuel Technology Development
Bibliographic record
Abstract
The Direct Use of Spent Pressurized Water Reactor (PWR) Fuel in Canada Deuterium Uranium (CANDU) Reactors (DUPIC) fuel technology has been developed by Korea, Canada and the United States (U.S.) since 1991 in order to utilize the PWR spent fuel in the CANDU reactor. The optimum fuel fabrication process was determined as the Oxidation and Reduction of Oxide Fuel (OREOX), based on the results of a feasibility study performed until 1993. Because the OREOX process uses only the thermal/mechanical process, the spent fuel standards are maintained throughout the process and the process is recognized as the most proliferation-resistant technology. In addition, because the amount of residual fissile isotopes in the PWR spent fuel is twice that of the natural uranium, the fuel burnup of the DUPIC fuel is twice that of the natural uranium fuel in the CANDU reactor. Therefore, as shown a direct disposal of the PWR spent fuel is no longer necessary, the natural uranium resources are preserved, and the amount of spent fuel from the CANDU reactor can be halved in the DUPIC fuel cycle. This paper summarizes the technical feasibility of the DUPIC fuel based on the research results obtained until now.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
