Prompt fission neutron spectra in the 235U(n,f) reaction [PDF]

EPJ Web of Conferences, 2023
Prompt fission neutron spectra (PFNS) are crucial to any neutronic simulation of critical nuclear systems. An experimental setup dedicated to the measurements of PFNS of very high accuracy was developed at the Los Alamos Neutron Science Center (LANSCE ...

Dams, Dams and More Dams: Issues in Evaluating Business Cases for Dam Expansion in Australia

Environmental Research Communications, 2023
Abstract Conventional interventions for mitigating flood risk and increasing water security often focus on large-scale engineering solutions despite evidence of significant cost overruns and negative environmental impacts. This study is an example of participatory research in water economics, motivated (and requested) by concerns from ...

The Dam of the Damned [PDF]

GeoHumanities, 2021
[EN] Over the last five decades, Italy has invested in the construction of public works as the core strategy to dynamize its less favoured regions; however, due to multiple and inherent dysfunctionalities, many of these remain half-built and abandoned today. The group of artists Alterazioni Video refer to this phenomenon as “Incompiuto” (“Incompletion”

Dam Break Analysis of Sermo Dam

Journal of the Civil Engineering Forum, 2023
Sermo Dam is located in the Special Region of Yogyakarta and serves multiple purposes including providing drinking water, supplementing irrigation systems in the Kalibawang area, and flood control. According to data published by the World Commission, 60% of mitigation measures taken to overcome the impact of dam structure failures are unsuccessful. The

Using dense seismo-acoustic network to provide timely warning of the 2019 paroxysmal Stromboli eruptions

Scientific Reports, 2021
Stromboli Volcano is well known for its persistent explosive activity. On July 3rd and August 28th 2019, two paroxysmal explosions occurred, generating an eruptive column that quickly rose up to 5 km above sea level. Both events were detected by advanced

Optimization of multipurpose reservoir system operation (Case study: Sefidrud and Shahryar reservoir dams) [PDF]

E3S Web of Conferences, 2022
Nowadays, effective water management becomes more vital all over the worlds. Due to the effect of climate change and population growth, reservoirs play a more important role in water resources management. Reservoirs can be used for multiple purposes such

Dam Safety: Use of Instrumentation in Dams

Journal of Earth Sciences and Geotechnical Engineering, 2020
Dam safety concerns do not stop at site selection, or the design and construction stages of a dam, but continue throughout its whole life. Seeing to safety issues of any dam is done by following up its behavior through visual observation supplemented and enriched by data collection from all the devices installed on or implanted in a dam to follow its ...

Production yields of micro-second isomers populated in 252Cf(SF) [PDF]

EPJ Web of Conferences, 2020
A twin Frisch grid ionization chamber loaded with an ultra-thin 252 Cf sample is used in order to detect spontaneous fission events. The chamber is surrounded by 8 HPGe detectors allowing to perform γ-spectroscopic measurements.

Accounting for speckle-scale beam bending in classical ray tracing schemes for propagating realistic pulses in indirect drive ignition conditions

Matter and Radiation at Extremes, 2023
We propose a semi-analytical modeling of smoothed laser beam deviation induced by plasma flows. Based on a Gaussian description of speckles, the model includes spatial, temporal, and polarization smoothing techniques, through fits coming from ...

Enhanced ion acceleration using the high-energy petawatt PETAL laser

Matter and Radiation at Extremes, 2021
The high-energy petawatt PETAL laser system was commissioned at CEA’s Laser Mégajoule facility during the 2017–2018 period. This paper reports in detail on the first experimental results obtained at PETAL on energetic particle and photon generation from ...
