[cdn-nucl-l] ITER : "Election delays Ottawa decision on reactor"



"a $12 billion nuclear reactor that mimics the sun to produce electricity" ?
I sure hope not -- trying to fuse protons likely wouldn't give us even a few
kilowatt-hours in a million years of operation. 
But it would certainly mimic the sun's great age :-)
(now if we were to mimic thermonuclear bombs, using deuterium and tritium,
we might have something !)

"ITER would use strong magnetic fields to squeeze ionized hydrogen gas to
reach temperatures of 100 million C, the same as on the sun."
Really ? ....that's news to me -- and an awful lot hotter than the sun's
interior, at about 15 million C.
Even Wolf-Ryet stars don't have a surface that hot -- maybe supernovae ?

Election delays Ottawa decision on reactor
PETER CALAMAI
SCIENCE REPORTER

OTTAWA-The federal cabinet is waiting until after Thursday's provincial
election to decide whether to support Ontario's bid for a $12 billion
nuclear reactor that mimics the sun to produce electricity.

The Eves government has been pressing Ottawa to match its own pledge of
$1.15 billion toward the construction and operation in Ontario of an
International Thermonuclear Experimental Reactor (ITER), an experimental
nuclear fusion reactor planned by the world's major industrialized nations.

As well, Liberal Leader Dalton McGuinty has promised to support the project
by matching any federal financial contribution. 

But the federal cabinet won't consider the ITER proposal until its regular
meeting next Tuesday at the earliest to avoid any suggestion of trying to
influence the provincial election, say sources close to the deal.

That timing would leave Canada's bid team with just one day's preparation
before a crucial Oct. 9 session of the ITER negotiating committee in Vienna.

"It's tight and we have to have a decision by then. The committee members
are already ranking the sites competing against us," said Murray Stewart,
president of the ITER Canada host team. 

Canada's ITER site is at the Darlington nuclear power station in Clarington.
Competing sites are being offered by Japan, France and Spain. 

ITER partners include the U.S., Russia, Japan, China, the European Union and
Canada. 

"Time is of the essence," agreed Toronto MP Art Eggleton (York Centre), head
of the GTA Liberal caucus.

Liberal MPs from the GTA and Ontario caucuses have been urging the cabinet
to sweeten the Canadian bid with $2.3 billion backing to be split between
Ottawa and the province.

Eggleton said the real cost amounts to $30 million for each government
annually over the 30-year life of the ITER project to "put Canada on the
leading edge of fusion research."

The industry-led team that made the initial ITER bid two years ago said then
that no federal cash was needed because of the natural advantages of the
Darlington site; electricity from the nuclear power station, tritium fuel as
a byproduct from Candu reactors and a nearby source of concrete to construct
the 13-storey ITER structure.

But competing bids from Japan and Europe upped the stakes and the Darlington
site now has no chance without $2.3 billion in government backing.

The ITER team originally hoped to get federal funds in June. But the
proposal ran into serious objections because Ottawa scrapped support for
fusion research during federal cost-cutting in the late 1990s.

"There has been some natural reluctance to get back into it," Eggleton said.

Fusion energy rests on the same atomic reaction that produces the sun's heat
and light by naturally fusing forms of hydrogen to produce helium.

fusion involves the strong nuclear force, with vastly different reaction
rates - Jaro]

ITER would use strong magnetic fields to squeeze ionized hydrogen gas to
reach temperatures of 100 million C, the same as on the sun.

ITER got a boost last week when U.S. experts said it was the most promising
and mature design for what physicists call a burning plasma experiment.

But scientists are also pursuing two other techniques for nuclear fusion and
no approach is expected to produce usable amounts of electricity for up to
40 to 50 years.
