28th IAEA Fusion Energy Conference, Nice, France, 10-15th May 2021

Understanding the effects of neutron irradiation of materials is one of the outstanding issues in the development of fusion technologies. The impact of this work derives from the opportunity, for the first time in a tokamak operating with a D-T plasma, to deliver experimental results which directly link to the nuclear characteristics of real sample…

The pedestal plays an important role in determining the confinement in tokamak H-mode plasmas. However, the steep pressure gradients in this transport barrier also lead to edge localized modes (ELMs) [1]. There is good understanding of the pedestal in type I ELM regimes [2], however, type I ELMs are known to damage plasma facing components and futu…

47th EPS Plasma Physics Virtual Conference, 21-25 June 2021

The disruption mitigation system at ITER will include four shattered pellet injectors (SPI), which will be dedicated to the mitigation of electro-magnetic loads (EML), thermal loads and the avoidance and suppression of runaway electrons. Recently the JETILW was equipped with an SPI with a wide capability. Specifically: pellet diameter d = [4.57, 8.…

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…

2021 IEEE International Conference on Robotics and Automation (ICRA),Xi’an China, 30 May - 5 June 2021

Driving energy consumption plays a major role in mobile robots navigating challenging environments, especially if they are left to operate unattended under limited on-board power. This paper reports on first results of an energy-aware path planner, which can provide estimates of the driving energy consumption and energy recovery of a robot traversi…

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

Sensor technologies will play a key role in the success of Remote Maintenance (RM) systems for future fusion reactors such as ITER and DEMO. Understanding their limitations and suitability for use in a fusion context is crucial to the operation and maintenance of these reactors. In this paper, we evaluate three key types of sensor which are of p…

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…
