Howard Cork Hayden, Emeritus Physics Professor, University of Connecticut: The most common question people bring up with respect to nuclear power is, “What do you do with the waste?” The answer requires discussion of three broad topics: the nature of uranium fission, radiation shielding, and the relationship between radiation and health. The first section is about the nature and the quantity of the high-level radioactive byproducts of uranium fission. This so-called “waste” from a nuclear reactor is different from the waste from burning coal. The second section discusses the nature of shielding and its effectiveness. The third section presents a simple mathematical proof that there is nothing inherently additive about radiation exposure.

IAEA, International Energy Agency, Jeremy Li: As the major research reactors that supply Mo-99 age and cease production, the alternative method discussed in the paper offers a simplified way to diversify production and help ensure continued supplies of Mo-99 so that nuclear medicine services are not interrupted. In 2009, reactors producing Mo-99 in Canada and the Netherlands were temporarily shut down for necessary repairs and maintenance. This caused major disruption in health care services worldwide, leading to cancelled medical scans and postponed operations, and in some cases requiring medical professionals to revert back to using old, less effective techniques.
IAEA, International Energy Agency: The Mo 99 supply chain will continue to remain fragile as long as it continues to rely on the same five aged production reactors. Given the way the supply chain has evolved --- particularly its reliance on only five multipurpose, non-commercial, government supported research reactors --- there are no clear market incentives to prompt new capacity or alternative supplies. No date on this document, but references indicate that it is 2009 or more recent.
