Determination of the activity inventory and associated uncertainty quantification for the CROCUS zero power research reactor

Andreas Pautz, Vincent Pierre Lamirand, Mathieu Hursin, DongHyuk Lee, Pavel Frajtag

The paper describes the source term estimation of CROCUS, the zero power research reactor of EPFL, to be used for dispersion analysis under accidental conditions. To fulfil regulatory requirements, the source term of the CROCUS fuel is estimated through Mo ...

Intercomparison of neutron noise measurement systems in the CROCUS reactor

Andreas Pautz, Vincent Pierre Lamirand, Oskari Ville Pakari, Mathieu Hursin

In the framework of an international collaboration, the critical decay constant (α0 = β/Λ), and delayed neutron fraction (β) of the CROCUS reactor were measured by teams of EPFL/PSI, CEA and SCK•CEN research institutes using the Rossi-α and Power Spectral ...

Anthropogenic- and natural sources of dust in peatland during the Anthropocene

Alexandre Buttler, Vincent Eric Jules Jassey, Mariusz Lamentowicz

As human impact have been increasing strongly over the last decades, it is crucial to distinguish human-induced dust sources from natural ones in order to define the boundary of a newly proposed epoch -the Anthropocene. Here, we track anthropogenic signatu ...

Products of in situ corrosion of depleted uranium ammunition in Bosnia and Herzegovina soils

Rizlan Bernier-Latmani, Barbora Bártová, Yuheng Wang, Konstantin von Gunten

Hundreds of tons of depleted uranium (DU) ammunition were used in previous armed conflicts in Iraq, Bosnia and Herzegovina, and Serbia/Kosovo. The majority (>90%) of DU penetrators miss their target and, if left in the environment, corrode in these postcon ...

Sampling-Based Nuclear Data Uncertainty Quantification for Continuous Energy Monte Carlo Codes

Ting Zhu

The goal of the present PhD research is to establish a methodology of nuclear data uncertainty quantification (NDUQ) for MCNPX, the continuous-energy Monte-Carlo (M-C) code. The high fidelity (continuous-energy treatment and flexible geometry modelling) of ...

Cyclic demand at the shell-bottom connection of unanchored steel tanks

Alain Nussbaumer, Gary Scott Prinz, Gustavo Cortes

Gasoline and other oil byproducts are commonly stored in steel tanks that rest on ground without any anchorage. Under strong motion, the impulsive mass of the contained liquid generates a moment about the base of the tank capable of causing partial uplift ...

On the low-cycle fatigue capacity of unanchored steel liquid storage tank shell-to-base connections

Alain Nussbaumer, Gary Scott Prinz

Under strong earthquake motions, the liquid stored within large unanchored steel tanks can cause rocking and uplift of the tank base from the supporting foundation. Repeated rocking can lead to low-cycle fatigue fractures in the tank base-plate, and ultima ...

Experimental Determination of the Capacity of Wall-to-Base Connections in Storage Tanks

Alain Nussbaumer, Gustavo Cortes, Eric Lattion

Earthquakes around the world have affected many unanchored tanks used for storage of gasoline. When these unanchored tanks are subjected to strong motion, the moment generated at the base, by the mass of liquid contained in the tank, will cause partial upl ...
