Eric Jelinski, past president of Environmentalists for Nuclear - Canada, farmer, environmentalist, university lecturer with degrees in mechanical, chemical and nuclear engineering: The question is really not, “Who can build nuclear?” but, “What does it take to build a nuclear plant,” and “How to build nuclear keeping within the capability of your country?” Here is a summary for pressure tube heavy water reactors, PTHW, developed in Canada and appropriate for other countries similar to Canada in the 1970s../p>
Poul Hoilund-Carlsen, Department of Nuclear Medicine Odense University Hospital, Denmark, Mohn Doss, Medical Physicist in Diagnostic Imaging: “The good rays - let them shine” appeared in European Journal of Nuclear Medicine highlighting the invalidity of the LNT model and asking for relaxation of restrictions for low doses involved in nuclear medicine. The two major journals in nuclear medicine – Journal of Nuclear Medicine (JNM) and EJNM are editorially aligned against the LNT model.
Jack Ponton, Emeritus Professor of Engineering at the University of Edinburgh, Fellow of the Royal Academy of Engineering: Most renewable energy enthusiasts now seem to understand that powering a modern society will require something else in addition to intermittent electricity generation. The currently fashionable ’something else’ is storage. This paper will discuss storage technologies, Britain’s current facilities and what might be needed to provide reliable power from wind, solar and tidal generation. There seems to be no possibility that any existing storage technology can handle the intermittency of wind generation. Solar plus battery storage is probably already cost-competitive for locations in or near the tropics, where year-round load factors are acceptable and so only overnight storage is required. In the UK, low winter load factors mean that essentially no useful generation takes place in December and January.
David Wojick, Heartland Institute, Ph.D. Philosophy of Science and Mathematical Logic, B.Sc. Civil Engineering: The brutal cold wave that just struck America provides a stark example of why 100% renewables cannot possibly work. Once the massive high pressure system was in place there was almost no wind, so no significant wind power. And the coldest temperatures by far were at night or early morning, when there was no solar power either. The first drawing shows Germany aiming for 100% wind and solar and they are using coal as backup, essentially no reduction in fossil fuel capacity. Colorado and California are mandating 100% wind and solar (with fossil fuel backup?). It is the worse possible energy plan for modern economies. Thank the politicians who planned this.
Kelvin Kemm is a nuclear physicist and Chairman of the South African Nuclear Energy Corporation and Nuclear Africa (Pty) Ltd: This is a broad brush picture of the nuclear power situation here. South Africa is the only country in Africa which has a nuclear power station. It is ‘Koeberg’ and it is situated close to Cape Town. It has been running for over 30 years and is recognised as one of the best run nuclear power stations in the world. A number of previous Koeberg senior managers and staff (about 80) are currently at the Baraka nuclear plant in the UAE, in significant positions, bringing that nuclear power station online.
