National Academy of Sciences, Committee on Medical Isotope Production Without Highly Enriched Uranium: Advanced nuclear reactors have been used successfully to produce vital radioisotopes for nuclear medicine. Certain physicists in the United States have worked since the 1970s to stop use of these reactors. This report was produced with the encouragement of scientists who are determined to deprive the United States of incredible amounts of energy. Russia and China ignore these decisions and rightfully so. They are determined to have modern economies with plutonium producing nuclear power. The conclusions were established first and the committee produced this report to satisfy the conclusions. The mandate to change radioisotope production from Highly Enriched Uranium, HEU, (with fast reactors) to Low Enriched Uranium, LEU, (without fast reactors) requires development of unproven technologies, pg. 134. That is a lot of government wordsmithing to meet the demands of anti-breeder reactor alarmists.
