Abstract

fetched live from OpenAlex

Different safety classification criteria and methods for systems, structures, and components (SSCs) of nuclear reactors, which are used among the countries exporting or importing nuclear reactor technology, could cause some difficulties in the nuclear technology trade and exchange. Thus, such different approaches of safety classification need to be harmonized to establish a global standard. The objective of this study is to propose a new practicable optimized criteria and method for safety classification of mechanical systems and components for water-moderated pool-type research reactors which have a core immersed in an open pool of water, that may be applicable for design, construction, operation, and maintenance of their systems, and components. The proposed safety classification criteria are derived from a comparative assessment study on the regulatory practices of SSCs safety classifications in various developed countries such as the Republic of Korea, United State, Canada, France, and the International Atomic Energy Agency (IAEA). The new compromised safety classification approach described in this thesis is applicable to general open pool type research reactors.

Teacher imitation

Not 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.
