Jan Willem Storm van Leeuwen is a consultant in chemistry and energy systems. Storm van Leeuwen received his Masters in Science, physical chemistry, at the Technical University Eindhoven. He is a senior scientist at Ceedata Consultants. He also develops courses for chemistry teachers for the Open University at Heerlen. He is the secretary of the Dutch Association of the Club of Rome. His two fields of expertise are technology assessment and life cycle analyses of energy systems, focussed on sustainability aspects. He published numerous reports and articles on various topics related to energy and environment.〔(【引用サイトリンク】 title=About the authors (Jan Willem Storm van Leeuwen and Philip Bartlett Smith) )〕 ==Nuclear energy study== He is best known for the paper ''Nuclear power the energy balance'' that he wrote with Philip Smith (also named ''Stormsmith studies''), where they analyzed the energy payback from the entire nuclear power system. The energy inputs were calculated based on various assumptions and guesses about the technologies used in uranium production, rather than actually measuring them. They concluded that the major parameter determining the energy balance was the grade of the uranium ore, and ore grades lower than 180 ppm do not yield an energy gain when used in the nuclear fuel cycle.〔 The study was heavily criticized, such as a rebuttal by researchers from the Paul Scherrer Institute.〔http://gabe.web.psi.ch/pdfs/Critical%20note%20GHG%20PSI.pdf Dones, Roberto, 2007.

The paper has been used by anti-nuclear organizations to claim that nuclear power is not clean enough to be considered a part of a clean energy mix. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jan Willem Storm van Leeuwen」の詳細全文を読む スポンサード リンク
