Journal ArticleDOI
Analysis of Transient Events Without Scram in a Research Reactor Using the RELAP5/MOD3.2 Computer Code
TL;DR: In this article, simulations of two different events without scramming were conducted for a hypothetical research reactor, based on the High-Flux Australian Reactor (HIFAR) moderated and cooled by heavy water circulating under atmospheric pressure.
Journal ArticleDOI
Synchronized chaotic targeting and acceleration of surface chemistry in prebiotic hydrothermal microenvironments
TL;DR: 3D chaotic thermal convection—flows that naturally permeate hydrothermal pore networks—supplies a robust mechanism for focused accumulation at discrete targeted surface sites, yielding two distinct processes that are seemingly opposed yet synergistically combine to accelerate surface reaction kinetics by several orders of magnitude.
Journal ArticleDOI
Effects of Nozzle Pressure Ratio and Nozzle-to-Plate Distance to Flowfield Characteristics of an Under-Expanded Jet Impinging on a Flat Surface
TL;DR: In this paper, the authors investigated the flow characteristics of an underexpanded turbulent jet impinging on a solid surface for various nozzle-to-plate distances 2.46 D j, 1.64 D j, and 0.82 D j (D j is the jet hydraulic diameter), and nozzle pressure ratios (NPRs) ranging from 2 to 2.77.
Journal ArticleDOI
Source terms modeling for spacer grids with mixing vanes for CFD simulations in nuclear reactors
TL;DR: A numerical method was developed to simulate the presence of spacer grids with mixing vanes in nuclear reactors fuel assemblies based on anisotropic second order closure models that applies also to one and two equation turbulence models, without lack of generality.
Journal ArticleDOI
Reactor cavity cooling system (Rccs) experimental characterization
TL;DR: The development of a new concept for a high temperature gas cooled reactor is strictly correlated to the Reactor Cavity Cooling System (RCCS) design as discussed by the authors, which is the latest heat sink designed to ensure the cooling down of the vessel and other structural materials during an accident scenario.
