Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

In fusion experiments, interruption units for high DC currents are widely used for generating the loop voltage required at plasma breakdown and current start-up. Likewise, similar systems are employed for the protection of superconductive coils in case of quench (i.e. a loss of superconductivity). In such event, large resistor banks are inserted in the circuits by means of circuit breakers, so as to dissipate the energy stored in the coils.The ITER experiment, the largest fusion facility ever conceived, is currently under construction in the south of France at Cadarache site and, as in the already existing fusion experiments, it will be provided with DC interruption units for plasma initiation (the Switching Network Units - SNUs) and coil quench protection (the Fast Discharge Units - FDUs).The paper, after a survey on the interruption units installed in large fusion facilities worldwide, describes the systems designed for the ITER experiment, pointing out their peculiarities and challenging issues. Then, a comparison among different solutions implemented is given, pointing out critical performances required, issues in the design of key components and possible future developments.
