This report presents the software engineering effort under way at ANL towards a comprehensive integrated computational framework (SHARP) for high fidelity simulations of sodium cooled fast reactors. The primary objective of this framework is to provide accurate and flexible analysis tools to nuclear reactor designers by simulating multiphysics phenomena happening in complex reactor geometries. ...

With significant technological advances in metabolic engineering, there are currently available efficient recombinant yeast strains capable of fermenting lignocellulosic sugars (i.e., glucose and xylose) to bioethanol. Conventional batch fermentation, preferred in most bioprocesses, may not provide the most appropriate environments for those engineered strains to perform their best. In this art...

A study was performed to investigate the impact of turbulent heterogeneity on aggregation and breakup in a flocculation reactor. The influence of the average characteristic velocity gradient (G), particle concentration, and coagulation mechanism on the flocculation performance was also investigated. Experiments were performed in a bench-scale reactor with a low-shear axial-flow impeller using a...

We perform extensive analysis on the physics of L-mode tokamak fusion reactors to identify (1) a favorable parameter space for a large scale steady-state reactor and (2) an operating point for a minimum scale steady-state reactor. The identification of the large scale parameter space is part of the 2008 MIT Nuclear Systems Design Project, which also includes sustainability and economic optimiza...

Design of an ammonia reactor was conceived as part a series item designs for plant in Cyprus. The Chemical and Mechanical aspects the design were considered. Optimization these studied, worked on, & discussed. safety, environmental legal regulations relevant followed concerned.
