Migrants' Smuggling is Knocking at the Danube's Door. Threats at the Romanian State Border

It is undeniable the devastating effect that the increase of the illegal migration has on the population, both in terms of access to the legal labor market and in socio-economic terms. This is the argument which supports our choice to analyze, through this scientific approach, the offenses of trafficking in migrants, an offense under art. 263 of the Criminal Code. We believe that the importance of the theme is special, especially because it represents one of the most acute manifestations of cross-border crime with consequences visible to victims and with side effects difficult to assess in the long term. The component of human trafficking, the illegal migration is a scourge increasingly widespread and difficult to contain due to the involved criminal networks, and the ingenuity of the offenders. Beyond the fact that this offense is committed, most often in the context of the organized crime (drug trafficking, arms smuggling, terrorism), the smuggling of migrants is a real danger to the socio-economic stability of states and even for peace and their security by disturbing the ethnic, cultural, demographic balance, by the inability of social protection mechanisms or public health, by exceeding the absorptive capacity of the market of legal work and implicitly, by upsetting the balance of forces between the control structures of legality and public order and the population channeled towards the criminal activities

Post-Test Numerical Analysis of a Helium-Cooled Breeding Blanket First Wall under LOFA Conditions with the MELCOR Fusion Code

The validation of numerical tools employed in the analysis of incidental transients in a fusion reactor is a topic of main concern. KIT is taking part in this task providing both experimental data and by performing numerical analysis in support of the main codes used for the safety analyses of the Helium Cooled Pebble Bed (HCPB) blanket concept. In recent years, an experimental campaign has been performed in the KIT-HELOKA facility to investigate the behavior of a First Wall Mock-Up (FWMU) under Loss Of Flow Accident (LOFA) conditions. The aim of the experimental campaign was twofold: to check the expected DEMO thermal-hydraulics conditions during normal and off-normal conditions and to provide robust data for code validation. The present work is part of these validation efforts, and it deals with the analysis of the LOFA experimental campaign with the system code MELCOR 1.8.6 for fusion. A best-estimate methodology has been used in support of this analysis to ease the distinction between user’s assumptions and code limitations. The numerical analyses are here described together with their goals, achievements, and lesson learn

Best-Estimate for System Codes (BeSYC): A New Software to Perform Best-Estimate Plus Uncertainty Analyses with Thermal-Hydraulic and Safety System Codes for Both Fusion and Fission Scenarios

The development and the validation of old and new software in relevant DEMO reactor conditions have been exploited in the latest years within the EUROfusion Consortium. The aim was to use—if possible—the software already validated for fission reactors and to fill the gaps with new ad-hoc software. As contribution to this effort, the Karlsruhe Institute of Technology (KIT) developed and tested a novel software to apply the Best-Estimate Model Calibration and Prediction through Experimental Data Assimilation methodology to the system codes RELAP5-3D, MELCOR 1.8.6, and MELCOR 2.2. This software is called Best-estimate for SYstem Codes (BeSYC), and it is developed as a MATLAB App. The application is in charge of applying the mathematical framework of the methodology, writing and executing the code runs required by the methodology, and printing the obtained results. The main goal of BeSYC is to wrap up the methodology in a software suitable to be used by any user through a simple graphical user interface. Albeit developed in the fusion research context, BeSYC can be applied to any reactor/scenario type supported by the specific system code. The goals of BeSYC, the mathematical framework, the main characteristics, and the performed verification and validation activities are described in this paper

Experimental Investigation of a Helium-Cooled Breeding Blanket First Wall under LOFA Conditions and Pre-Test and Post-Test Numerical Analysis

The experimental investigation of a prototypical set‐up simulating a loss of flow accident in a helium‐cooled breeding blanket first wall mock‐up under typical heat load conditions is presented. The experimental campaign reproduces the expected DEMO thermal‐hydraulics conditions during normal and off‐normal situations and aims at providing some insight into the fast transients associated with the loss of flow in the blanket first wall. The experimental set‐up and the definition of the experimental matrix are discussed, including pre‐test analysis performed in support of these activities. The major experimental results are discussed, and a procedure of using the acquired data for validating and calibrating the RELAP‐3D model of the mock‐up is introduced. All these activities contributed to the creation of a relevant theoretical and practical experience that can be used in further studies concerning incidental transients in real‐plant scenarios in the framework of DEMO plant fusion safety activities

Excited states in Sm139 described with the interacting boson model plus broken pairs

The high-spin structure of Sm139 has been studied through the Pd110(34S,5n) reaction at beam energies of 150 and 165 MeV. The level scheme has been extended up to an excitation energy of 11.1 MeV and spin 61/2+. A band built on the νi13/2 [660]1/2+ intruder orbital has been established and firmly linked to the known lower-spin levels in the nucleus. The low-lying states of both parities as well as a relatively strong ΔI=1 regular structure observed above spin 27/2- are nicely reproduced by the interacting boson-fermion model with broken pairs
