Why does Greenpeace oppose nuclear power?
Nuclear power isdirty, dangerous and expensive. With
cancer-causing emissions andradioactive waste, nuclear power is not
a clean alternative to fossilfuels. Greenpeace supports a total
phase-out of nuclear power inCanada.
How many nuclear plants are there in Canada?
There aretwenty-two nuclear power reactors in Canada - twenty in
Ontario, one inQuebec and one in New Brunswick. Eight of the
twenty reactors inOntario were shut down in 1997 due to poor
performance and safetyproblems. Since then, several reactors have
been restarted athigh-cost. After massive cost over-runs during
the restart of two ofthe reactors at the Pickering A nuclear
station, the remaining tworeactors were permanently mothballed in
August 2005.
Quebec iscurrently discussing whether it should rebuild its only
nuclearreactor, Gentilly-2. New Brunswick is pushing ahead with
plans torebuild its only reactor, the Point Lepreau nuclear station
in 2008.
How is the nuclear industry funded in Canada?
Atomic Energy ofCanada Limited (AECL) is the federal crown
corporation that designs andmarkets CANDU reactors. Since it was
founded in 1952, AECL hasreceived over $20 billion in tax-payer
subsidies. Since 2000, AECL hasbeen given over a billion dollars
in subsidies. In addition, theOntario government has indirectly
subsidized Ontario Power Generation'snuclear power plants by
relieving them of billions of dollars of debt.
What is radioactive waste?
Radioactive wasteis created at each step in production of nuclear
power - from uraniummining in Saskatchewan, to reactor operation,
and finally to theclosure and decommissioning of nuclear stations.
.
What is oftenreferred to as high-level radioactive waste is the
spent fuel fromnuclear plants. It contains over one hundred
different radioactiveisotopes that cause cancer and other health
problems. This waste islethal and must be kept isolated from the
environment for hundreds ofthousands of years.
'Low-'and'Intermediate' wastes are other non-fuel radioactive
wastes created bynuclear energy, including everything from
radioactive clothescontaminated at nuclear stations to the reactor
components that willremain a threat for thousands of years to
come.
Mining andprocessing uranium for reactor fuel produces wastes known
as tailings. There are currently over 200 million tons of uranium
tailings inOntario and Saskatchewan. These wastes remain a hazard
for thousandsof years and contain carcinogens, such as radium,
radon gas, thoriumamong others.
What happens to nuclear waste in Canada?
Nuclear wastecannot be safely disposed of or destroyed. There are
about 40,000tonnes of high-level radioactive waste (spent fuel) in
Canada with morethan 30,000 tonnes in Ontario. Currently, most of
Canada nuclear fuelwaste is stored at the nuclear plants where it
has been produced.
What is the government's long-term plan for nuclear
waste?
In 2002, theCanadian government mandated a nuclear
industry-controlled agencycalled the Nuclear Waste Management
Organization (NWMO) to propose along-term solution for the disposal
of high-level nuclear waste (spentfuel). The nuclear industry has
always advocated the burial ofhigh-level nuclear waste in the
granite formations of the CanadianShield.
The federalgovernment gave NWMO a three-year mandate to choose
between threeradioactive waste management alternatives: "deep
geological disposal inthe Canadian Shield"; "storage at nuclear
sites"; or "centralizedstorage".
In 2005, the NWMOasked the federal government for permission to
proceed with a proposalthat combined all three flawed waste
management alternatives called'Adaptive Phased Management.' The
300-year, $24 billion "phased"approach moves used nuclear fuel
wastes from storage at nuclear plants,to centralized storage, and
finally to deep rock disposal. It says thehigh-level radioactive
waste dump should be located in either Quebec,Ontario, or
Saskatchewan.
The industry-controlled NWMO refused to consider phasing
out the production of nuclear waste.
The nuclearindustry is moving forward with proposals to bury
non-fuelradioactive wastes as well. Ontario Power Generation plans
to buryso-called low and intermediate-level waste at the Bruce site
on theshore of Lake Huron. Atomic Energy of Canada Limited has
proposed tobuild deep geological repository for its radioactive
wastes at itsChalk River Laboratories on the shore of Ottawa River,
100 km north ofOttawa.
Neither NewBrunswick Power nor Hydro-Quebec has a proposal for how
they safelywill management their long-lived radioactive wastes for
thousands ofyears.
What is the Greenpeace position on radioactive
waste?
Radioactive wasteremains dangerous for hundreds of thousands of
years and deep rockburial cannot guarantee that it will remain
isolated from theenvironment. Radioactive waste should be left on
or near the earth'ssurface and closely monitored storage
facilities.
Is the Canadian nuclear industry correct when it says that a
Chernobyl-type accident is "not possible in Canada"?
No. Canada'sCANDU nuclear reactor is no safer than any other
reactor design. Human error, terrorist attack or technical failure
could cause ameltdown at any of Canada's nuclear stations.
Following theaccident at the American Three Mile Island nuclear
station in 1979, anall-party committee of the Ontario Legislature
(the Select Committee onHydro Affairs) investigated Ontario's
nuclear policies. In its 1980report to the legislature, the
committee concluded that:
"It is notright to say that a catastrophic accident (in a
CANDU reactor) isimpossible ... The worst possible accident could
involve thespread of radioactive poisons over large areas, killing
thousandsimmediately, killing others through increasing
susceptibility tocancer, risking genetic defects that could affect
future generations,and possibly contaminating, for further
habitation, large land areas...
Accidents,mistakes and malfunctions do occur in [CANDU] nuclear
plants: equipmentfails; instrumentation gives improper readings;
operators andmaintainers make errors and fail to follow
instructions; designs areinadequate; events that are considered
`incredible' happen...no matterhow careful we are, we must
anticipate the unexpected."
Is the nuclear industry confident that a nuclear accident
will never happen in Canada?
No. Despitenuclear industry claims that a Chernobyl-type accident
is "not possiblein Canada," the nuclear industry requires special
financial liabilityprotection from the federal government in case
of a major nuclearaccident. The federal Nuclear Liability Act
limits that amount offinancial liability of any nuclear reactor
operator to $75 million - aminiscule fraction of the likely actual
cost of a nuclear disaster.
Is theCanadian nuclear industry correct to say that a
Chernobyl-type accidentcould happen in Canada because of "Canada's
Candu technology"?
No. CANDU reactors also share the following similarities with the
RBMK reactors at Chernobyl:
1. Ontario'snuclear stations and Chernobyl are four-reactor
stations with sharedsafety systems. Sharing of safety systems
reduces redundancy andincreases the risk of radiation release.
2. Both reactordesigns employ fuel channels (as opposed to one
large pressurizedreactor vessel), including pressure tubes made of
the same alloy. Thesetubes incorporate hydrogen over time, causing
tubes to become brittleand breakable.
3. While mostreactors have to be shut down every year or two for
refuelling, CANDUand RBMK reactor designs allow for on-line
refuelling. This has thepotential to improve performance, but it
also can increase the lengthof time without inspection or
maintenance. Chernobyl reactor 4 had beenoperating for over two
years non-stop when it exploded on April 26 1986.
4. CANDU is theonly reactor design outside the former Soviet
Union, that like theRBMK, has a positive void effect. Steam
formation in the reactor coreincreases reactivity (more nuclear
fissions taking place), increasingpower levels, causing more steam
formation and resulting in a loss ofregulation accident.
What have other countries done to avoid a Chernobyl-type
accident?
In 2000, Germanycommitted to phasing out nuclear power and phasing
in clean, greenrenewable energy. Germany's then-Environment
Minister Jurgen Trittinsaid that phasing out nuclear power was "a
logical response toChernobyl."
In a referendumfollowing Chernobyl accident, Italy voted to abandon
nuclear powercompletely in 1987. Italy subsequently closed all of
its reactors andplaced a moratorium on the construction of new
nuclear stations.
What is Greenpeace doing?
Greenpeace isworking to end government subsidies to the nuclear
industry and tophase out nuclear power. We are lobbying to
prevent the restart andreconstruction of old reactors and against
the deep rock burial ofradioactive waste.
