31st Symposium on Fusion Technology (SOFT), Dubrovnik, Croatia, 20 - 25 September 2020

In order to reach commercially-relevant availability future fusion power plants must have highly efficient maintenance systems. On the other hand, as radiation levels increase so too will the number of maintenance tasks that must be performed without human access.  To meet these conflicting constraints remote maintenance systems must significantly…

2021 PVP Virtual Conference, 12-16 July 2021

The use of small specimen test techniques (SSTT) to determine mechanical properties of irradiated materials has been studied over the previous decades both in fission and fusion programs, but also to characterise and optimise new materials by nuclear and non-nuclear communities. Currently a number of activities are running that focus on the sta…

Hi Stuart, Thank you for your comments and for improving some of the text. Regarding the minor edits, I have all applied them to the paper. The larger edits, I have highlighted in the annotated document with comments below. Regarding the localisation of the various processes, I agree this is an important subject and should be addressed in mor…

30th Symposium on Fusion Technology (SOFT), Giardini Naxos, Messina, Sicily, 16-21 September 2018

Pre-conceptual design studies for a European Demonstration Fusion Power Plant (DEMO) have been in progress since 2014.  At this stage, while a range of design options are being considered, it is essential that assessments are carried out of the safety and environmental impact of these options.  This is not only to ensure that the DEMO plant is op…

14th International Symposium on Fusion Nuclear Technology (ISFNT-14) Budapest,Hungary, 22-27 September 2019

Just like most industrial or scientific installations, future fusion reactors will require more or less frequent maintenance. The expected environmental conditions, as well as the necessity of carrying out many maintenance tasks in parallel in result in remote robotic maintenance becoming a necessity in order to minimize the maintenance shutdown du…

Measurements made using flush-mounted Langmuir probes (FMPs) in tokamaks are difficult to interpret when operating at grazing angles of magnetic field incidence due to the effects of sheath expansion on the probe collection area. The super-X divertor on the upgraded Mega Ampere Spherical Tokamak (MAST-U) will have very shallow angles of magnetic fi…

31st Symposium on Fusion Technology (SOFT), Dubrovnik, Croatia, 20 - 25 September 2020

DEMO is a key part of the EU fusion roadmap, and the programme reaches the end of the pre-conceptual phase with a gate review in 2020. As part of the work to complete this phase, eight Key Design Integration Issues (KDII’s) have been identified as critical to the programme. Two of these KDII’s identified a requirement for a more detailed archit…

14th International Symposium on Fusion Nuclear Technology (ISFNT-14) Budapest,Hungary, 22-27 September 2019

The creation of 3-D CAD models is one of the key steps in the fusion reactor design cycle, and is very much a recurring process. A common division of labour sees engineers, draughtspeople, and analysts iterate ideas, requirements and constraints, 3-D CAD model(s), and analyses, respectively, to iteratively converge upon a working design. Whilst thi…

27th IAEA Fusion Energy Conference, Ahmedabad, India, 22-27 October 2018

The JET exploitation plan foresees D-T operations in 2019-2020. With respect to the first D-T campaign in 1998, when JET was equipped with a carbon wall, the experiments will be conducted in presence of a beryllium-tungsten ITER-like wall and will benefit from an extended and improved set of diagnostics and higher available additional heating power…
