Radioactive
waste from nuclear power plants can be in solid, liquid, or
gaseous forms. Some of the types and quantities of possible
nuclear waste are noted below.
"Depleted
Uranium (DU) is, according to the to the Military Toxins Project,
the radioactive byproduct of the uranium enrichment process,
is "roughly 60% as radioactive as naturally occurring
uranium and has a half-life of 4.5 billion years."
The United States has in excess of 1.1 billion pounds
of DU waste material."
"Low
Level Radioactive Waste (LLW) is any radioactive waste not
classified as high-level waste, transuranic waste, or uranium
mill tailings. LLW often contains small amounts of radioactivity
dispersed in large amounts of material. It is generated by
uranium enrichment processes, reactor operations, isotope
production, medical procedures, and research and development
activities. LLW is usually made up of rags, papers, filters,
tools, equipment, discarded protective clothing, dirt, and
construction rubble contaminated with radionuclides."
"Sewage
sludge is what is left over after raw sewage has been treated
at the wastewater treatment plants. Water and many of the
contaminants are removed from the raw sewage; Bacteria are
then left to do the job of reducing human waste, leaving a
concentrated semisolid sludge cake. In the past, wastewater
treatment plants paid to for disposal of sludge in landfills
or through incineration. Over one third of the 5.3 million
metric tons of sewage sludge produced each year in the US
is now dumped on farmland and forestland. Sludge isn't just
"fertilizer." Heavy metals, parasites (and other
pathogens), chemicals such as chlorine can all be contained
in sewage sludge. But the 503 regs don't include testing or
treatment for radioactivity in sludge, which can originate
from industry, the medical profession and labs."

from Sierra Club web site, Nuclear
Waste
Few people
dispute that nuclear power plants do produce nuclear waste.
What is in dispute is how dangerous this waste is, whether
it can be safely disposed of, and how does this waste compare
with the air pollution from other fossil fuel power plants.
