BWR loss-of-coolant accident tests at ROSA-III with high temperature emergency core coolant injection. [PDF]

Journal of Nuclear Science and Technology, 1988
The effects of emergency core coolant (ECC) temperature on the performance of the emergency core cooling system (ECCS) during a loss-of-coolant accident (LOCA) of a boiling water reactor (BWR) were investigated experimentally using the Rig of Safety Assessment (ROSA)-III integral test facility.

Experimental study on burning rate and flame geometry in construction tunnel fires under high geothermal conditions

Deep Underground Science and Engineering, EarlyView.
Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

Deep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas

Deep Underground Science and Engineering, EarlyView.
This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

Effect of Spray System on Fission Product Distribution in Containment During a Severe Accident in a Two-Loop Pressurized Water Reactor

Nuclear Engineering and Technology, 2016
The containment response during the first 24 hours of a low-pressure severe accident scenario in a nuclear power plant with a two-loop Westinghouse-type pressurized water reactor was simulated with the CONTAIN 2.0 computer code.

Sprayable Polyolefin Sorbents Enabled by Bio‐Solvents for Large‐Scale Oil and Chemical Spill Recovery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sprayable POE‐based sorbent formulated with a green solvent blend of α‐pinene, D‐limonene, and p‐cymene enables rapid in situ film formation via solvent evaporation, allowing efficient pollutant capture. The system exhibits high oil uptake (37.3 g g−1) and effectively removes up to 60 mL of VLSFO under simulated marine spill conditions.

PWR LOSS-OF-COOLANT ACCIDENT CORE MELTDOWN CALCULATIONS

, 1957
Results are presented of a study made of the possible extent of zirconium-water reaction and core meltdown following a postulated loss-of-coolant accident in the PWR plant. Zirconium-water chemical reaction and core meltdown occur in the course of the core temperature excursion which could follow a loss- of-coolant if no cooling were provided after an ...

Quality of Spontaneous and Backslopped Fermented Cassava Flour From Different Cassava Landraces and Sensory Acceptability of the Cooked Dough

Food Chemistry International, EarlyView.
The cooked Oko‐iyawo spontaneously fermented cassava flour's sensory acceptability was correlated with its amylose content, pH, pasting temperature, and water absorption capability. Cassava processors may be able to create consistently high‐quality fermented cassava flour for various end users with the use of the information provided in this study ...
