Ambivalent nuclear technologies use or have a potential to produce nuclear weapon relevant materials like highly enriched uranium (HEU), plutonium, tritium and U233. It is important to assess the proliferation potential and measures to strengthen the proliferation resistance of these technologies as early as possible (preventively) to find alternative more proliferation resistant designs or at least to identify sensitive parameters or even critical parts that should trigger international safeguards and export controls.

The conclusions of different case studies investigating the proliferation resistance of nuclear technologies such as spallation neutron sources, tokamak fusion reactors and plutonium fuels will be briefly presented. The main part of the talk will focus on the minimization or elimination of civil HEU usage and the role of research reactor conversion to the use of low enriched uranium, which is intrinsically more proliferation resistant. The conversion of the German high flux research reactor FRM-II will serve as an example for the complex political and technological challenges and problems one has to face, especially, if proliferation concerns are not taken seriously in the research and design phase. These case studies of relatively disparate nuclear technologies have in common that they are neutron producing technologies and some questions regarding their proliferation potential can be addressed using neutronic codes.

Finally, the talk will briefly outline the future research of the next year addressing centrifuge technology as another case study to explicate on exemplary basis general criteria for the proliferation resistant use of nuclear technologies.

Matthias Englert is a postdoctoral fellow at CISAC. Before joining CISAC in 2009, Matthias was a researcher at the Interdisciplinary Research Group Science Technology and Security (IANUS) and a PhD student at the department of physics at Darmstadt University of Technology in Germany. 

His major research interests include nonproliferation, disarmament, arms control, nuclear postures and warheads, fissile material and production technologies, the civil use of nuclear power and its role in future energy scenarios and the possibility of nuclear terrorism.  His research during his stay at CISAC focuses primarily on the technology of gas centrifuges for uranium enrichment, the implications of its use for the nonproliferation regime and on technical and political measures to manage the proliferation risks. 

Matthias has been participating in projects investigating technical aspects of the concept of proliferation resistance with topics spanning from conversion of research reactors, uranium enrichment with gas centrifuges, reducing plutonium stockpiles with reactor based options,  spallation neutron sources and fusion power plants. Further research topics included fissile material stockpiles, fuel-cycles and accelerator  driven systems. Although a substantial part of his professional work of the last years was quite technical he is equally interested in and actively studies the historical, social and political aspects of the use of nuclear technologies. Research interests include the dispute about Article IV of the NPT, the future development of the NPT regime, possibilities for a nuclear weapon free world, preventive arms control, and history and development of proliferation relevant programs. By studying contemporary theory in philosophy of the interaction of science, technology and society, Matthias acquired analytical tools to reflect on approaches describing or addressing the problem of ambivalent technology.

Matthias is a vice speaker of the working group Physics and Disarmament of the German Physical Society (DPG) and a board member of the  German Research Association for Science, Disarmament and Security (FONAS).

Abstract
Despite the promise, the majority of mobile technology solutions are only meeting the needs of a small percentage of organisations who could benefit from them. In his talk, Ken Banks will discuss how he empowers grassroots NGOs, provide the history and background to FrontlineSMS, and highlight some of the challenges in developing mobile tools which work in resource-constrained environments

Ken Banks, founder of kiwanja.net, devotes himself to the application of mobile technology for positive social and environmental change in the developing world, and has spent the last 16 years working on projects in Africa. Recently, his research resulted in the development of FrontlineSMS, an award-winning text messaging-based field communication system designed to empower grassroots non-profit organisations. Ken graduated from Sussex University with honours in Social Anthropology with Development Studies, and was awarded a Stanford University Reuters Digital Vision Fellowship in 2006, and named a Pop!Tech Social Innovation Fellow in 2008. In 2009 he was named a Laureate of the Tech Awards, an international awards program which honours innovators from around the world who are applying technology to benefit humanity. Ken's work has been supported by the MacArthur Foundation and Open Society Institute, and he is the current recipient of a grant from the Hewlett Foundation

Summary of the Seminar
Ken Banks, the founder of kiwanja.net, spoke about the importance of technology solutions that meet the needs of those working in the developing world and his own work in this area through FrontlineSMS.

While current excitement in the technology world may be focused on increasing centralization through cloud computing, this means little to people working in the developing world where internet connectivity is unavailable or unreliable.  Too little investment is going into building tools that will genuinely assist the work many non-profits are doing now.

Ken developed FrontlineSMS to tap into the potential of mobile phones, which are now widely available and used in the developing world. This is a two way communication system that can be used anywhere where there is a mobile phone signal.  FrontlineSMS is available as a free download and Ken's approach has been not to dictate implementation but rather to allow people to use this very general tool in whatever ways meet their particular needs. This has resulted in diverse applications, for example:

• Monitoring election practices in Nigeria in 2007
• Sending security alerts to humanitarian workers in conflict areas of Afghanistan
• Encouraging young people to take part in elections in Azerbaijan
• Updating local people on the location of speeches during President Obama's visit to Ghana

There is also great potential to combine FrontlineSMS with traditional media, such as radio, that is already widespread throughout Africa, to make this much more interactive.

Ken offered a number of points of guidance for those thinking about designing technology with social applications:

• Work with the equipment that people already have at their disposal
• Make equipment easy to assemble and intuitive
• Price it at a level people can afford
• Think about how use can be replicated - how will other NGOs find out about it?
• Assume a situation of no internet connectivity
• Where possible, give users an ability to connect with others - for example through a forum (this has been particularly successful at FrontlineSMS, with a third of those who download the software joining the online community)
• Don't let a social science approach dominate - it is much better to think in a multi-disciplinary way
• Use technology that is appropriate to the context - don't bring in tools that require knowledge and equipment not already held in the community
• Collaborate, don't compete. Sometimes NGOs can rush to do the same things; examples of genuine cooperation are hard to find

Looking ahead, Ken will be developing functionality for FrontlineSMS that makes use of internet connectivity where this is available. He is also working on finding additional funding to help organizations pay for text messages.
