Control rods effect analyses on thermo-hydraulic safety parameters in TRR [PDF]

مجله علوم و فنون هسته‌ای, 2020
In this study, the effect of control rods on TRR safety parameters was investigated in both cases of static and transient behavior. In this paper, the effect of the control rods movements (70%) on the power peaking was used in the form of the normalized ...

CFD Analysis of Passive Autocatalytic Recombiner

Science and Technology of Nuclear Installations, 2011
In water-cooled nuclear power reactors, significant quantities of hydrogen could be produced following a postulated loss-of-coolant accident (LOCA) along with nonavailability of emergency core cooling system (ECCS). Passive autocatalytic recombiners (PAR)

A Lab on a Chip Experiment for Upscaling Diffusivity of Evolving Porous Media

Energies, 2022
Reactive transport modelling is a powerful tool to assess subsurface evolution in various energy-related applications. Upscaling, i.e., accounting for pore scale heterogeneities into larger scale analyses, remains one of the biggest challenges of ...

Computational Fluid Dynamics Modeling of Steam Condensation on Nuclear Containment Wall Surfaces Based on Semiempirical Generalized Correlations

Science and Technology of Nuclear Installations, 2012
In water-cooled nuclear power reactors, significant quantities of steam and hydrogen could be produced within the primary containment following the postulated design basis accidents (DBA) or beyond design basis accidents (BDBA).

Amyloid adhesin production in activated sludge is enhanced in lab-scale sequencing batch reactors: Feeding regime impacts microbial community and amyloid distribution

Water Research X, 2022
Amyloid adhesins are β-sheet-rich extracellular proteins thought to contribute to bioflocculation. They are present in activated sludge to varying extent. However, it remains unclear which operational conditions promote their production. To this end, the

Generalized Reich-Moore R-matrix approximation

EPJ Web of Conferences, 2017
A conventional Reich-Moore approximation (RMA) of R-matrix is generalized into a manifestly unitary form by introducing a set of resonant capture channels treated explicitly in a generalized, reduced R-matrix.
