Numerical Study on Design Optimization of Sodium-cooled Fast Reactor Core Catcher

Yuanzineng kexue jishu
In the event of core disassembly accident (CDA) in a sodium-cooled fast reactor (SFR), the molten material from the core migrates and interacts with the low-temperature coolant in the lower plenum, resulting in the formation of core debris that ...

Study on application of artificial neural network to debris bed coolability calculations for sodium-cooled fast reactors

Mechanical Engineering Journal, 2020
Understanding the effect of uncertainties of Core Disruptive Accident (CDA) scenarios on debris bed coolability on a core catcher is required for decision making on design options to mitigate a CDA consequence.

A Direct-Push Freezing Core Barrel for Sampling Unconsolidated Subsurface Sediments and Adjacent Pore Fluids

Vadose Zone Journal, 2018
Contaminants passing through the unsaturated zone can undergo changes in narrow reaction zones upon reaching saturated sediments. Understanding these reactions requires sampling of sediment together with adjacent water and microbes in a manner that ...

Transient Investigation of Conceptual Twin Crucible Type Core Catcher Design with Embedded Cooling Tube Using GOTHIC 3D Model

Yuanzineng kexue jishu
In case of a severe accident, the lower head of the reactor pressure vessel will be melted when the corium cannot be effectively cooled after melting. Under the EVR (ex-vessel corium retention) strategy, the molten corium will be released into the core ...

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

FEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis

Advanced Functional Materials, EarlyView.
Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.

Inverse Design of Amorphous Materials With Targeted Properties

Advanced Materials, EarlyView.
AMDEN is a diffusion model framework for the inverse design of amorphous materials with targeted properties. By incorporating Hamiltonian Monte Carlo refinement into the denoising process, the framework overcomes the challenge of generating thermally relaxed disordered structures.

A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

Advanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.
