Design Features and Simulation of the New-Build HELOKA-US Facility for the Validation of the DEMO Helium-Cooled Pebble Bed Intermediate Heat Transport and Storage System

Journal of Nuclear Engineering, 2022
For the EU-DEMO Helium-Cooled Pebble Bed (HCPB) concept, an indirect coupled design (ICD) with a molten salt (MS) loop as an intermediate heat transport and storage system (IHTS) is considered for the conceptual design phase.

DERMA: A Melanoma Diagnosis Platform Based on Collaborative Multilabel Analog Reasoning

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
The number of melanoma cancer‐related death has increased over the last few years due to the new solar habits. Early diagnosis has become the best prevention method. This work presents a melanoma diagnosis architecture based on the collaboration of several multilabel case‐based reasoning subsystems called DERMA.

Use of Nuclear Data Sensitivity and Uncertainty Analysis for the Design Preparation of the HCLL Breeder Blanket Mockup Experiment for ITER

Science and Technology of Nuclear Installations, Volume 2008, Issue 1, 2008., 2008
An experiment on a mockup of the test blanket module based on helium‐cooled lithium lead (HCLL) concept will be performed in 2008 in the Frascati Neutron Generator (FNG) in order to study neutronics characteristics of the module and the accuracy of the computational tools. With the objective to prepare and optimise the design of the mockup in the sense
