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 ...

Closed‐Loop Radiative Cooling Mulch Upcycled From Agricultural Residues for Efficient Soil Heat–Water Stress Mitigation

Advanced Science, EarlyView.
Conventional passive radiative cooling films rely on costly feedstocks and energy‐intensive fabrication, with poor end‐of‐life compatibility in agriculture. To address this challenge, a sustainable radiative cooling mulch (SRCM) is developed from waste maize leaves via spontaneous hydrogen‐bond self‐assembly.
