Abstract

fetched live from OpenAlex

The LR-56 cask is an International Atomic Energy Agency (IAEA), type B (U) certified Medium to High Level Radioactive Liquid Waste Transport Cask. The LR-56 consists of a trailer equipped with the following component and systems: cubic meter lead shielded cask; Self-contained ventilation system including an air pressure/vacuum pump for cask loading and unloading; Waste temperature, level, leak detection, and other surveillance equipment; Control room for control of loading and unloading operations and waste surveillance; Hoist system for removing well caps on the cask; Power connection and control connections for operating the cask from a remote facility; The cask may be unloaded or loaded using either the onboard pressure/vacuum pump or by an external waste transfer pump. Rinse heads and connections allow the cask to be rinsed using supplied rinse water. The cask was designed to be vented using the LR-56 onboard ventilation system, which is connected to the cask via a hose through a penetration in the cask. Three wells located on the top of the cask, offer valved penetrations into the cask for venting, waste pumping, and rinsing. Other penetrations in the cask enable surveillance instrumentation to be used to monitor inside the cask. To date, the LR-56 cask system at the Hanford facility has not been used. Since the vessel has never received radioactive waste, the LR-56 is not yet a regulated system. It is desired to use the LR-56 cask to transport waste in calendar year 2000.

Not 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.
