Fast Monte Carlo codes for occupational dosimetry in interventional radiology
(2021-05)
Article
Restricted access - publisher's policyInterventional radiology techniques cause radiation exposure both to patient and personnel. The radiation dose to the operator is usually measured with dosimeters located at specific points above or below the lead aprons. ... -
On the use of CFD to obtain head loss coefficients in hydraulic systems and its application to liquid metal MHD flows in nuclear fusion reactor blankets
(2021-12-01)
Article
Restricted access - publisher's policyWhen an incompressible fluid flows through a contraction in a conduit, the increase in the kinetic energy of the fluid is accompanied by a pressure drop. This pressure drop is not to be assimilated with head loss. If ... -
Liquid metal MHD flow influence on heat transfer phenomena in fusion reactor blankets
(2021-09-01)
Article
Restricted access - publisher's policyDEMO reactor is projected as a technological demonstrator and a component test reactor for several key systems such as the breeding blanket. The dual coolant lithium lead (DCLL) is one promising breeding blanket candidate ... -
New metrology for radon at the environmental level
(2021-09-23)
Article
Open AccessRadon gas is the largest source of public exposure to naturally occurring radioactivity. However, radon is also a useful tracer for understanding atmospheric processes, assessing the accuracy of chemical transport models, ... -
Dynamic simulation tools for isotopic separation system modeling and design
(2021-08-01)
Article
Restricted access - publisher's policyCryogenic distillation is the best candidate for hydrogen isotopic separation in fusion power plants. The design of the ITER's Isotope Separation System can still undergo major changes due to its close contact with the ... -
Application of a BEPU-based code assessment to the ATLAS upper head SB-LOCA test
(2021-12-15)
Article
Open AccessThe prevailing state of knowledge of two-phase flow in complex systems, as in the nuclear field, usually leads a certain degree of ad hoc calibration of computational models and the consequent inevitable subjectivity in ... -
Validation of the MC-GPU Monte Carlo code against the PENELOPE/penEasy code system and benchmarking against experimental conditions for typical radiation qualities and setups in interventional radiology and cardiology
(2021-02-01)
Article
Restricted access - publisher's policyIntroduction: Interventional procedures are associated with potentially high radiation doses to the skin. The 2013/59/EURATOM Directive establishes that the equipment used for interventional radiology must have a device ... -
Comparison of airborne radiation detectors carried by rotary-wing unmanned aerial systems
(2020)
Article
Open AccessThe Universitat Politecnica de Catalunya (UPC), the Physikalisch-Technische Bundesanstalt (PTB) and the German Federal Office of Radiation Protection (BfS) have analysed the response of a 2”x2” (diameter x height) NaI and ... -
Analysis of flow channel insert deformations influence on the liquid metal flow in DCLL blanket channels
(2020-08-01)
Article
Open AccessThe dual coolant lithium lead (DCLL) is a candidate to be an effective breeding blanket (BB) concept for nuclear fusion technologies. One critical point of this design is the magnetohydrodynamic (MHD) effects involving ... -
A first prototype of C6D6 total-energy detector with SiPM readout for neutron capture time-of-flight experiments
(2021-01-01)
Article
Open AccessLow efficiency total-energy detectors (TEDs) are one of the main tools for neutron capture cross section measurements utilizing the time-of-flight (TOF) technique. State-of-the-art TEDs are based on a CD liquid-scintillation ... -
Advanced tools for ITER Tritium Plant System Modeling & Design
(2020-01-01)
Article
Open AccessChemical plant system modeling experience based on the use of largely validated commercial modeling tools such as the Aspen HYSYS is adapted and exploited to develop numeric routines for unitary isotopic operations, including ... -
New local optics measurements and correction techniques for the LHC and its luminosity upgrade
(American Physical Society (APS), 2020-04-06)
Article
Open AccessAs the beams at the interaction points (IPs) of circular colliders are pushed toward smaller sizes, the correction of the magnetic field errors in high- ß regions become increasingly important, but also challenging. This ...
