The disposal of nuclear waste is becoming a major concern. Many
nuclear power plants around the world are nearing the end of their
operating lives. This is particularly true in the United States
where most nuclear power plants are approaching the end of the
operational time period allowed in their licenses. The disposal of
radioactive waste from nuclear power plants and nuclear missiles is
as politically intense an issue as the plants and missiles
themselves. Yet the three issues have remained curiously separate
in spite of their close physical ties. Few debates on nuclear power
or nuclear weapons discuss the problems of waste disposal should
the power plant or missile be decommissioned. Few debates on
nuclear waste disposal discuss the opportunities to close nuclear
power plants or get rid of nuclear weapons a disposal site would
afford. Nuclear waste can be generally classified a either "low
level" radioactive waste or "high level" radioactive waste. Low
level nuclear waste usually includes material used to handle the
highly radioactive parts of nuclear reactors (i.e. cooling water
pipes and radiation suits) and waste from medical procedures
involving radioactive treatments or x-rays. Low level waste is
comparatively easy to dispose of. The level of radioactivity and
the half life of the radioactive isotopes in low level waste is
relatively small. Storing the waste for a period of 10 to 50 years
will allow most of the radioactive isotopes in low level waste to
decay, at which point the waste can be disposed of as normal
refuse. High level radioactive waste is generally material from the
core of the nuclear reactor or nuclear weapon. This waste includes
uranium, plutonium, and other highly radioactive elements made
during fission. Most of the radioactive isotopes in high level
waste emit large amounts of radiation and have extremely long
half-lives (some longer than 100,000 years) creating long time
periods before the waste will settle to safe levels of
radioactivity. This new book explores the issues pertaining, either
directly or indirectly, to nuclear waste disposal.
