The ICRP Task Group on Internal Dosimetry is developing new Occupational Intakes of Radionuclides documents, which will include revised dose coefficients for inhalation of radionuclides by workers. Application of the ICRP Human Respiratory Tract Model requires a review of the lung-to-blood absorption characteristics of inhaled materials of importance in(More)
The gas injection system (GIS) is an indispensable part of ITER fueling system. It deliveries the necessary gas species from tritium plant to vacuum vessel, pellet injection system or neutral beam for plasma operation and fusion power shutdown. In this paper, the current design status of GIS, including the previousdesign changes, is brieflydescribed. As(More)
The “Things We Do for No Reason” (TWDFNR) series reviews practices which have become common parts of hospital care but which may provide little value to our patients. Practices reviewed in the TWDFNR series do not represent “black and white” conclusions or clinical practice standards, but are meant as a starting place for research and active discussions(More)
The poloidal field (PF) coil system on ITER, which provides both feedforward and feedback control of plasma position, shape, and current, is a critical element for achieving mission performance. Analysis of PF capabilities has focused on the 15 MA Q = 10 scenario with a 300-500 s flattop burn phase. The operating space available for the 15 MA ELMy H-mode(More)
This paper focuses on unsupervised curve classification in the context of nuclear industry. At the Commissariat à l’Energie Atomique (CEA), Cadarache (France), the thermal-hydraulic computer code CATHARE is used to study the reliability of reactor vessels. The code inputs are physical parameters and the outputs are time evolution curves of a few other(More)
Experiments in Alcator C-Mod in EDA H-modes with extrinsic impurity seeding (N 2 , Ne, Ar) have demonstrated a direct correlation between plasma energy confinement and edge power flow achieving values of H 98 ≥ 1 for edge power flows only marginally exceeding the scaled power for access to H-mode confinement in these conditions. For lower Z impurity seeding(More)
Assessment of plasma parameters is carried out for low activation phase required for commissioning the basic ITER systems including plasma control, heating and current drive, etc. Such operation is analyzed for hydrogen , helium and deuterium plasmas for full field and current as well as with magnetic field and plasma current reduced to half of their design(More)
The purpose of the work is to review interim results of the Joint Study on assessment of an Innovative Nuclear System based on a Closed Nuclear Fuel Cycle with Fast Reactors (INS CNFC-FR). This study is a part of the IAEA international project for innovative reactors and fuel cycle technologies (INPRO). Now it is being implemented by Canada, China, France,(More)
With the development of heterogeneous camera networks working at different wavelengths and frame rates and covering a large surface of vacuum vessel, the visual observation of a large variety of plasma and thermal phenomena (e.g., hot spots, ELMs, MARFE, arcs, dusts, etc.) becomes possible. In the domain of machine protection, a phenomenological diagnostic(More)
