A Required Level of Enhancing Life Safety Derived from the Cost for Substituting Nuclear Energy in Japan
Bibliographic record
Abstract
Since the disastrous earthquake and tsunami on March 11, 2011, Japanese people have discussed the question of “How safe is safe enough?” The risk of spills from nuclear power plants is one of the major issues, and the government has shut down almost all nuclear power plants to re-evaluate the risk from each one. However, even after the re-evaluation, the nuclear power plants remain closed because many people do not agree with the evaluation, and they prefer to avoid as much risk as possible without fully understanding the cost of their demands. Currently, to sustain the electric demand with thermal power plants, Japan must import more fossil fuel at great cost. This study provides a comprehensible cost-benefit criterion for enhancing life safety. The criterion provides a required level of enhancing life safety which equivalents with the additional cost for substituting nuclear energy and importing other energy sources. This suggested criterion could be used as a benchmark to evaluate the actual reduced risk by prohibiting the nuclear power plants’ operation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
