Validation of Two Monte Carlo Codes for LWR Burnup Calculations

Mathieu Hursin, Hakim Ferroukhi, Damar Canggih Wicaksono, Alexander Vasiliev

This paper presents an assessment conducted at the Paul Scherrer Institut (PSI) of two Monte Carlo-based codes, namely Monteburns and Serpent, for LWR depletion calculations. First, a validation of predicted spent fuel compositions is presented on the basi ...

Linking bacterial population dynamics and nutrient removal in the granular sludge biofilm ecosystem engineered for wastewater treatment

Christof Holliger, David Gregory Weissbrodt, Noam Shani

Intensive nutrient removal from wastewater in anaerobic–aerobic systems using granular sludge should rely on optimal balances at biofilm and microbial ecology levels. This study targets the impacts of reactor characteristics and fluctuations in operation c ...

Intrinsic momentum transport in up–down asymmetric tokamaks

Justin Richard Ball

Recent work has demonstrated that breaking the up–down symmetry of tokamak flux surfaces removes a constraint that limits intrinsic momentum transport, and hence toroidal rotation, to be small. We show, through MHD analysis, that ellipticity is most effect ...

Thermal-Hydraulic Analysis of LTS Cables for the DEMO TF Coil

Kamil Sedlák

Two preliminary design concepts for the low T-C. superconductor Toroidal Field coil system of the planned European fusion reactor DEMO were proposed in 2012 by EPFL-CRPP PSI Villigen and ENEA Frascati. The coil consists of eight double layers (DLs) wound u ...

Non-stationarity in experimental travel time measured in a lysimeter: theoretical and modeling lessons from a simplified hydrological system

Andrea Rinaldo, Enrico Bertuzzo, Pierre Claude Jean Queloz, Luca Carraro, Gianluca Botter

Experimental data have been collected over a year-long period in a large weighing lysimeter. Natural climatic forcing occurs, except for rainfall which is artificially generated as a given Poisson process at a daily timescale. A constant water table is mai ...

Structural Melting of an Amino Acid Dimer upon Intersystem Crossing

Thomas Rizzo, Ulrich Lorenz

We present a spectroscopic investigation of the excited-state dynamics of the phenylalanine (Phe)/serine (Ser) protonated dimer in the gas phase. Using an ultraviolet (UV) laser pulse, we promote individual isomers to the S1 state and probe their fate with ...

Implementation of cell-free biological networks at steady state

Sebastian Maerkl, Henrike Marie Niederholtmeyer, Viktoria Stepanova

Living cells maintain a steady state of biochemical reaction rates by exchanging energy and matter with the environment. These exchanges usually do not occur in in vitro systems, which consequently go to chemical equilibrium. This in turn has severely cons ...

Multi-injection microstructured reactor for intensification of fast exothermic reactions: proof of concept

Albert Renken, Lioubov Kiwi, Thomas Maeder, Bo Jiang, Julien Haber

Quasi-instantaneous exothermic reactions lead to the formation of unwanted hot spots even when carried out in conventional microstructured reactors (MSR) with tube diameter of 100 − 1000 μm. For this reason, alternative MSR designs are warranted to enable ...

Effect of hot spots in microstructured reactors on product distribution during quasi-instantaneous exothermic reactions

Albert Renken, John Richard Thome, Lioubov Kiwi, Thomas Maeder, Navid Borhani, Bo Jiang, Julien Haber

Background. The small characteristic sizes (in the range of 102 - 103 μm) of Microstructured reactors (MSR) lead to very high specific interfacial area which, in turn, increases heat- and mass transfer efficiency. However, for quasi instantaneous exothermi ...
