Appendix: Information on Nuclear Reactors v :Ethics and Nuclear Energy Technology and Nuclear Energy :Ethics vi Ethics and Nuclear Energy Technology and Nuclear Energy Ethics PREFACE The report stems from the work of many authors and scholars. Much of this was completed under the framework of Working Group 12 established by the Regional Unit in Social and Human Sciences in Asia and the Pacific (RUSHSAP) at UNESCO Bangkok under the Ethics and Climate Change in Asia and the Pacific (ECCAP) project. The ethics of nuclear energy technology, as one of the applications of science and technology, is one of the most contentious issues facing human society globally. There are benefits and risks, and how wil leach society balance these? Some countries are adopting the technology to produce electricity, and others are rejecting it. The UN aims to encourage science and value-based discussions on environmental ethics to produce substantive cross-cultural and multidisciplinary outputs that will be relevant for long-term policy making. The aim of the ECCAP project is not to formulate universal economic or political plans of how to deal with these issues. Rather, the working groups of the project aim to increase awareness and discussion of the complex ethical dilemmas related to energy and the environment, and to identify scientific data, and available ethical frameworks of values and principles for policy options that have proven useful in facing the challenges in certain communities and countries. The report was developed by a working group with members from across the region, who participate as individuals in the highest standards of intellectual vigour and integrity, integrating engineers, philosophers, policy makers, experts, youth, and persons of many different cultural backgrounds and experiences. The reports are subject to ongoing open peer review, and the principal vii authors are listed. There is ongoing discussion of numerous reports on the yahoo group, unesco_eet@ yahoogroups.com, that are in various stages of drafting. For all reports, drafts and outlines of others, and specific requests for further case studies and analyses, please examine the working group webpages which list the members, and the overall website, http://www.unescobkk.org/rushsap/energyethics. The report writers thank Technology and Nuclear Energy :Ethics all members of the ECCAP project, and in particular WG12, and Ms. Nobuko Yasuhara for comments.

Defined as the activity of a quantity of radioactive material in which one nucleus decays per second. Btu: British thermal unit. Defined as the amount of energy needed to raise the temperature of 1pound of water by 1 degree Fahrenheit at 1 atmosphere of pressure. CANDU: Canada Deuterium Uranium Reactor uses uranium dioxide pellets with natural uranium (enriched with 0.7% 235U) CCGT: Combined Cycle Gas Turbine Power Plant.

As we consider the ethics of science and technology, nuclear power has always been dreaded as something risky, while
