Pit problems for Cameco
19 Sept 08 MATTHEW GAUKThe Prince Albert Daily HeraldThe sand walls of the radioactive tailings pit at the largest uranium mill in the world have been tumbling down, according to a report to the Canadian Nuclear Safety Commission…………………the sloughing sand has resulted in a 19 per cent loss of capacity in the pit, leaving a serious waste management problem for Cameco.

Nuclear Denial

September 18, 2008Nuclear Denial RENEWABLE ENERGY WORLD by Michael MellishNuclear power plants have a productive life of at least forty years. Unfortunately unlike other power plants, after forty years they cannot simply be decommissioned, razed and the site redeveloped into other uses.Fuel rods used in nuclear power plants are actively exothermic (generating heat) for up to seventy-five years after removal from the reactor…………………………Today, the fuel rods have to stay in the ponds on the site because there is no other place for them to go. The U.S. doesn’t operate a fuel rod processing plant (like BNFL does for the United Kingdom) and has no current plans for such a vitrification facility (imbedding the active radio active waste within glass). Even then the glass-encased radioactive material must be actively cooled for 75 years, so it must be kept somewhere with human management of the site.
Who is going to pay for this? Consider the cost of staffing for 75 additional years when there is no revenue stream from electrical generation to cover this, and there is no easy way to pass the cost onto the electrical customers. This problem is only starting to be recognized since so few reactors have actually reached the end of life in the U.S. If you check the balance sheets of the major electrical utilities that own and operate nuclear power plants, you will not see any allowances for this future cost. It would be simpler to spin off the plant, let it go bankrupt and leave it to the taxpayers to deal with the mess……………………………The operation of existing nuclear power plants, labs and facilities has been fraught with accidents, incidents and discharges throughout the 50-year history of nuclear power. Full and open disclosure of the accidents and risks taken by operators (including the U.S. government) remains dubious at best…………………………Uranium mining and processing of uranium ore to fuel grade is hardly a “clean” activity. Vast quantities of overburden must be removed to mine the ore (with all the attendant pollution problems). The ore itself is quite difficult to process, separating the useful material U235 from its counterparts clearly produces significant quantities of radioactive waste products, dust and chemical wastes from the separation process, all of which are quite nasty.

NZ nuclear ban will remain whoever wins election – International Herald Tribune

NZ nuclear ban will remain whoever wins election
The Associated Press18 Sept 08

The conservative front-runner in the race to become New Zealand’s
next prime minister says he would make no big changes to the country’s
foreign and defense policies, and the nuclear ban that has long been a
thorn in Washington’s side would remain.

“America will never like our anti-nuclear stance but there’s a
recognition that it’s there and is going to stay,” National Party
leader John Key told The Associated Press in an interview Wednesday………………………..Famous for its “Lord of the Rings” wilderness, this South Pacific
nation of 4.3 million people, dairy and sheep farms, wineries and a
handful of cities is in general socially conservative but progressive
on issues such as protecting the environment…………..

Since 1985, U.S. warships have been denied entry into New Zealand
ports because the Pentagon refuses to declare if they are carrying
nuclear weapons. As a result, New Zealand has been effectively dropped
from a joint security treaty with the U.S. and Australia.

Relations have improved recently — U.S. Secretary of State
Condoleezza Rice paid a visit in July and praised New Zealand despite
their differences — and both Clark and Key say they are hopeful of
striking a free trade agreement with the United States.

Key said “the independent nuclear policy will remain” if he is prime minister.
