Radiation hazards in PF-1000 plasma generator Fusion Research (part 2)
Journal of Radioanalytical and Nuclear Chemistry, 2015Co-Authors: Kamil Szewczak, S. JednorogAbstract:This paper focuses on radiation exposures to Researchers and technicians involved in Fusion Research. It is the second article in the series on this topic. It discusses immediate exposures to the ionizing radiation that is generated immediately during Fusion Research performed on the PF-1000, a dense magnetized plasma generator that is the world’s largest.

Radiation hazards in PF-1000 plasma generator Fusion Research
Journal of Radioanalytical and Nuclear Chemistry, 2015Co-Authors: Kamil Szewczak, S. JednorogAbstract:Fusion Research poses significant radiation hazards, including prompt as well as delayed exposures. Prompt radiation consists of deeply penetrating neutrons and gamma rays, whereas delayed exposure derives from nuclear decays that were previously activated by neutrons. The PF-1000 plasma focus device, a dense magnetized plasma generator, is a source of all of these radiation hazards. The aim here is to assess the delayed radiation hazard of the PF-1000 device to the operational crew and Research scientists.

Atomic and molecular physics issues in current thermonuclear Fusion Research
Contemporary Physics, 2005Co-Authors: Ratko K. JanevAbstract:The crucial role of atomic and molecular collision processes in a number of outstanding issues in current magnetic Fusion Research is discussed. These issues are related to the achievement and control of thermonuclear burn conditions, thermal power and particle exhaust, and the optimization of Fusion reactor performance. The status of the present knowledge on the characteristics of collision processes (cross sections, reaction rate coefficients) involved in these Fusion Research issues is presented. Significant gaps in this knowledge that prevent a full understanding of the background physics of the above mentioned Fusion Research problems and may affect the ways of their solution are identified. One of the purposes of the present article is to provide a motivation for undertaking the necessary atomic and molecular physics studies for bridging these gaps.

Status report on Fusion Research
Nuclear Fusion, 2005Co-Authors: Werner BurkartAbstract:A major milestone on the path to Fusion energy was reached in June 2005 on the occasion of the signing of the joint declaration of all parties to the ITER negotiations, agreeing on future arrangements and on the construction site at Cadarache in France. The International Atomic Energy Agency has been promoting Fusion activities since the late 1950s; it took over the auspices of the ITER Conceptual Design Activities in 1988, and of the ITER Engineering and Design Activities in 1992. The Agency continues its support to Member States through the organization of consultancies, workshops and technical meetings, the most prominent being the series of International Fusion Energy Conferences (formerly called the International Conference on Plasma Physics and Controlled Nuclear Fusion Research). The meetings serve as a platform for experts from all Member States to have open discussions on their latest accomplishments as well as on their problems and eventual solutions. The papers presented at the meetings and conferences are routinely published, many being sent to the journal it Nuclear Fusion, co-published monthly by Institute of Physics Publishing, Bristol, UK. The journal's reputation is reflected in the fact that it is a world-renowned publication, and the International Fusion Research Council has used it for the publication of a Status Report on Controlled Thermonuclear Fusion in 1978 and 1990. This present report marks the conclusion of the preparatory phases of ITER activities. It provides background information on the progress of Fusion Research within the last 15 years. The International Fusion Research Council (IFRC), which initiated the report, was fully aware of the complexities of including all scientific results in just one paper, and so decided to provide an overview and extensive references for the interested reader who need not necessarily be a Fusion specialist. Professor Predhiman K. Kaw, Chairman, prepared the report on behalf of the IFRC, reflecting members' personal views on the latest achievements in Fusion Research, including magnetic and inertial confinement scenarios. The report describes Fusion fundamentals and progress in Fusion science and technology, with ITER as a possible partner in the realization of self-sustainable burning plasma. The importance of the socio-economic aspects of energy production using Fusion power plants is also covered. Noting that applications of plasma science are of broad interest to the Member States, the report addresses the topic of plasma physics to assist in understanding the achievements of better coatings, cheaper light sources, improved heat-resistant materials and other high-technology materials. Nuclear Fusion energy production is intrinsically safe, but for ITER the full range of hazards will need to be addressed, including minimising radiation exposure, to accomplish the goal of a sustainable and environmentally acceptable production of energy. We anticipate that the role of the Agency will in future evolve from supporting scientific projects and fostering information exchange to the preparation of safety principles and guidelines for the operation of burning Fusion plasmas with a Q > 1. Technical progress in inertial and magnetic confinement, as well as in alternative concepts, will lead to a further increase in international cooperation. New means of communication will be needed, utilizing the best resources of modern information technology to advance interest in Fusion. However, today the basis of scientific progress is still through journal publications and, with this in mind, we trust that this report will find an interested readership. We acknowledge with thanks the support of the members of the IFRC as an advisory body to the Agency. Seven chairmen have presided over the IFRC since its first meeting in 1971 in Madison, USA, ensuring that the IAEA Fusion efforts were based on the best professional advice possible, and that information on Fusion developments has been widely and expertly disseminated. We further acknowledge the efforts of the Chairman of the IFRC and of all authors and experts who contributed to this report on the present status of Fusion Research.

Summary of the 12th IAEA technical meeting on control, data acquisition and remote participation for Fusion Research
Nuclear Fusion, 2019Co-Authors: Matteo Barbarino, K. BehlerAbstract:This report summarizes the contributions presented at the 12th IAEA technical meeting on control, data acquisition and remote participation for Fusion Research, held in Daejeon, Republic of Korea, 13–17 May 2019. The meeting brought together more than 70 experts from nuclear Fusion Research sites worldwide. The main topics of the meeting were plasma control; machine control, monitoring, safety and remote manipulation; data acquisition and signal processing; database techniques for information storage and retrieval; advanced computing and massive data analysis; remote participation and virtual laboratory; and fast network technology and its application.
