New build: tackling the cost issue
Food for thought: New build: tackling the cost issue: http:// analysis.nuclearenergyinsider.c om/new-build/ new-build-tackling-cost-issue?u tm_source=http%3A%2F%2Fuk.nucl earenergyinsider.com%2Ffc_nei_ decomlz%2F&utm_medium=email&ut m_campaign=NEI+e-brief+2908&ut m_term=New+build%3A+tackling+t he+cost+issue&utm_content=1518 99
..."So when comparing a wind or solar farm to a nuclear power plant,
the immediate and long-term costs also have to be relative to the
quality of power you are getting every day and basically over the next
few decades. If nuclear plant costs are transparent throughout the
plant's economic cycle including recycling the spent fuel--while at the
same time communicating to stakeholders and the public of the benefits
received (reliable power, job creation, R&D innovation)--then the
'nuclear bill' may not be so hard to swallow. "

CAP member survey on NSERC's DG, RTI and MRS programs
The results of the CAP member survey on NSERC's DG, RTI and MRS programs are now available on the CAP's website: http://www.cap.ca/en/news/ 2012-08-27/ summary-capnserc-survey-results -and-observations ..."78% agree that it will be difficult to maintain and/or grow their research infrastructure with only the CFI program."
CAP submission to House of Commons Finance Committee
CAP submission to House of Commons Finance Committee: http://www.cap.ca/en/news/ 2012-07-29/ cap-submission-house-commons-fi nance-committee
... among recommendations is to preserve the basic research
capabilities currently housed in federal organizations: "While the
economy will benefit from industry-driven research at AECL and NRC,
which are being restructured, these organizations also support basic
research and access to large-scale research infrastructure. The basic
research capacity at other federal organizations, such as CSA and
Environment Canada, is being reduced. Transferring these functions to
other organizations may be the best way to preserve them if these
functions no longer fit their current organizational mandates." the full
pdf document is found at this link... will any one listen???
The other noteworthy
recommendation is to create a Minister of Science, Technology and
Innovation (STI): "The Jenkins report recommended creating a Minister
for Innovation. In fact, Canada needs a Minister that can give full
attention to the entire STI spectrum because of the critical importance
of STI to productivity, and because technological innovation cannot be
separated from the research that makes it possible.
Ultimately,
these improvements will translate into more research outcomes such as
technological advances that increase productivity overall."

New neutron generation: Going from tubes to chips
Sandia National Laboratories’ work on neutron generation: Going from tubes to chips: https://share.sandia.gov/news/resources/news_releases/neutron_generator/
"It was a figurative whack on the head that started Sandia National Laboratories distinguished technical staff member Juan Elizondo-Decanini thinking outside the box — which in his case was a cylinder.
He developed a new configuration for neutron generators by turning from conventional cylindrical tubes to the flat geometry of computer chips. For size comparison, small neutron generators, which are like mini accelerators, are 1 to 2 inches in diameter, he said.
“The idea of a computer chip-shaped neutron source — compact, simple and inexpensive to mass-produce — opens the door for a host of applications,” Elizondo-Decanini said.
The most practical, and the most likely to be near-term, would be a tiny medical neutron source implanted close to a tumor that would allow cancer patients to receive a low neutron dose over a long period at home instead of having to be treated at a hospital, he said."
Also worth repeating is the benefits of having national labs: "Elizondo-Decanini’s vision for the neutron generator of the future is one that uses no tritium and no vacuum, is made in a solid state package and is fabricated at Sandia’s Microsystems and Engineering Sciences Applications (MESA) complex.
“That has very dramatic technology implications and challenges,” he said. “But that’s what I tell people, that’s what the national labs are all about.”"

The Pontecorvo Affair: a Cold War Defection and Nuclear Physics
Simone Turchetti
2012 University of Chicago Press £29.00/$45.00hb 292pp
Cold War science
I was a teenager in Hungary when I first heard that the nuclear
physicist Bruno Pontecorvo had defected from the West to the Soviet
Union. The communist press praised his defection as a testament to the
superiority of Soviet science and Soviet life, but to us it was a great
puzzle, and it has remained one for more than 60 years. His action was
unique, as no other well-known scientist ever defected from the West to
the East. Defections in the opposite direction were less extraordinary.
The latest attempt at fathoming his actions is The Pontecorvo Affair.
Written by the University of Manchester historian Simone Turchetti, the
book provides an informative account of Pontecorvo's life up to his
defection. Although it does not offer an unambiguous explanation for the
event itself, it does go some way towards satisfying the historian's
curiosity about Pontecorvo's motivations. Curiosity about the second
half of the physicist's life, however, is left entirely unsatisfied, as
the book more or less avoids discussing how he adapted to life behind
the Iron Curtain.
Merkel’s Green Shift Forces Germany to Burn More Coal
Merkel’s Green Shift Forces Germany to Burn More Coal: http://www.bloomberg.com/news/2012-08-19/merkel-s-green-shift-forces-germany-to-burn-more-coal-energy.html ... too bad: "The startup of the 2,200-megawatt station near Cologne last week shows how Europe’s largest economy is relying more on the most-polluting fuel. Coal consumption has risen 4.9 percent since Merkel announced a plan to start shutting the country’s atomic reactors after last year’s Fukushima disaster in Japan.
Germany’s largest utilities RWE and EON AG (EOAN) are shunning cleaner-burning natural gas because it’s more costly, while the collapsing cost of carbon permits means there’s little penalty for burning coal. Wind and solar projects, central to Germany’s plans to reduce nuclear energy and cut the release of heat- trapping gases, can’t produce electricity around the clock.
“Angela Merkel’s policy has created an incentive structure which has the effect of partially replacing nuclear with coal, the dirtiest fuel that’s responsible for much of the growth in the world’s greenhouse-gas emissions since 1990,” Dieter Helm, an energy policy professor at the University of Oxford, said by phone Aug. 17. Building new coal stations means “locking them in for the next 30 years” as a type of generation, Helm said.
Germany’s increasing coal consumption is part of a global return to the fossil fuel that’s cheaper than most alternatives. The amount of coal burned worldwide rose 5.4 percent to account for 30 percent of total energy use last year, the highest proportion since 1969, according to BP Plc (BP/) data."
Nuclear power is the key to slowing global warming
A good read: Nuclear power is the key to slowing global warming http://www.nj.com/ times-opinion/index.ssf/2012/ 08/ opinion_nuclear_power_is_the_k. html
..."Almost half of the emissions reductions have come from power
plants, particularly the switch away from coal in electricity
generation. Coal’s share is forecast to fall below 40 percent for the
year, down from 54 percent just four years ago, and by the end of this
decade, it’s likely to be near 30 percent. The principal replacement
source has been natural gas, which has less than 50 percent of coal’s
carbon content. Had the switch been to nuclear power, which produces
zero emissions, the decline would have been far greater. And nuclear
power would be far better for public health, since it doesn’t pollute
the air.
Yet many environmental leaders, though by no means all,
oppose the use of nuclear power. Denying the vital role nuclear plants
play in the battle against climate change is crazy, given that nuclear
power accounts for 70 percent of the carbon-free energy in the United
States. New Jersey receives 50 percent of its electricity from nuclear
power plants."

irrational fears of nuclear energy to block the building of a
significant number of new nuclear plants, we will be choosing a far more
perilous option: the intensified burning of planet-warming fossil
fuels."

Nuclear power project in Canada receives site preparation license
Nuclear power project in Canada receives site preparation license: http://www.power-eng.com/ articles/2012/08/ nuclear-power-project-in-canada -receives-site-preparation-lic ense.html
..."The Joint Review Panel (JRP) of the Canadian Nuclear Safety
Commission (CNSC) on August 17 said it will issue a Nuclear Power
Reactor Site Preparation License to Ontario Power Generation Inc. (OPG)
for its new nuclear power plant project at the Darlington nuclear site
for a period of 10 years. The license will be valid from Aug. 17, 2012
to Aug. 17, 2022.
In June 2012, OPG announced it had signed
agreements with Westinghouse and SNC-Lavalin/Candu Energy Inc., to
prepare detailed construction plans, schedules and cost estimates for
two potential nuclear reactors at the Darlington Nuclear site.
During a 17-day public hearing held March 21 to April 8, 2011 in
Courtice, Ontario, the JRP received and considered submissions from OPG
and 264 interveners, as well as 14 government departments, including the
CNSC.
“This decision is an important milestone in Canada’s nuclear history,” said Alan Graham, chair of the JRP.
The JRP said it is satisfied that the licensee meets the requirements
of section 24 of the Nuclear Safety and Control Act, that OPG is
qualified to carry out the activities that will be permitted under the
license, and that the health and safety of people and the environment
will be protected."

Candu strike is leading to brain drain, union warns
Candu strike is leading to brain drain, union warns: http://www.theglobeandmail.com/report-on-business/candu-strike-is-leading-to-brain-drain-union-warns/article4483047/ ..."SNC-Lavalin Group is mired in a lengthy strike with unionized engineers and scientists at its Candu Energy unit that is raising concerns about a brain drain at the company and its ability to provide service to Canada’s nuclear-power operators.
The battle is part of the restructuring at the Candu division of former Atomic Energy of Canada Ltd., which SNC purchased from Ottawa for $15-million last year. The federal government had grown frustrated by AECL’s constant cost overruns which were backstopped by taxpayers, and SNC made it clear it intended to force more commercial discipline on the former Crown corporation." ... "The “anecdotal evidence” of the loss of senior engineers and scientists worries Candu customers like Duncan Hawthorne, chief executive officer at Bruce Power which is restarting two reactors after a lengthy and much-delayed refurbishment.“There definitely has to be some level of concern” about the labour dispute, Mr Hawthorne said in an interview Wednesday. “These people are the heart and soul of the Candu design, and to the extent some of that is lost, it could hurt the industry.”
The country’s nuclear power stations don’t depend on Candu Energy for routine operations and maintenance, but Mr. Hawthorne says its expertise can be critical for specific problems or in a major retooling. A spokesman at Ontario Power Generation – which owns nuclear stations at Pickering and Darlington – said its operations are unaffected by the strike.
SPEA vice-president Mike Ivanco, who works as a scientist at Candu Energy, said SNC-Lavalin let go about 100 people after formally taking over in October, but then had to hire most of them back. Since then, some 70 senior engineers and scientists have left, he said."

Clean energy ‘mega-trend’ sweeping globe, Canadian economy left vulnerable, Harper government told in briefings
Clean energy ‘mega-trend’ sweeping globe, Canadian economy left vulnerable, Harper government told in briefings: http://www.canada.com/ technology/ Clean+energy+mega+trend+sweepin g+globe+Canadian+economy+left+ vulnerable+Harper+government+t old/7043569/story.html
..."A dependence on fossil fuel resources is making the country
vulnerable to a planetary “mega trend” toward low-carbon energy that
“will affect the whole of Canada’s economy,” Natural Resources Minister
Joe Oliver was told in newly released internal briefing notes.
“While Canada has an enviable energy resource advantage, its future
success cannot be taken for granted,” said the briefing notes. “It must
make smart decisions now in order to get ahead of emerging challenges.
The country will need to further diversify its energy sources, ensure
that it has secure access to global markets and find ways to meet the
growing demand for energy at home in ways that are environmentally
sustainable and publicly acceptable.”
Noting that Canada was last
among G8 nations in terms of clean energy investments, the briefing
notes prepared by bureaucrats at Natural Resources Canada for Oliver
after he was appointed to cabinet in May 2011, explained that the growth
of emerging economies such as China and India was one “mega trend”
influencing the economy and demand for resources and energy.
But the
documents also suggested that other countries were getting ahead of
Canada in a new market, estimated to be worth $6.5 trillion in
2007-2008, for green products and services aimed at lowering carbon
dioxide and other greenhouse gas emissions that trap heat in the
atmosphere and contribute to global warming.
“Over the medium term,
the world is being shaped by another mega trend — the beginning of a
transition towards a lower-carbon economy,” said the briefing notes,
marked secret but declassified for release to Postmedia News under
access to information legislation. “While fossil fuels will remain a
dominant source of global energy for decades to come, leading economies,
including the US and China are making major investments to position
themselves as low-carbon leaders.”"

The Panic Over Fukushima
a must read: The Panic Over Fukushima: http://online.wsj.com/article/SB10000872396390444772404577589270444059332.html ...physicist Richard Muller (University of California, Berkeley) write in WSJ that Japan's government overreacted to the Fukushima nuclear disaster evoking the natural radiation levels in Denver, Colorado, which are high enough to trigger the immediate evacuation of the city - at least if guidelines from the International Commission on Radiological Protection are strictly applied! and in case you are wondering Denver has lower-than average cancer mortality... "The tsunami that hit Japan in March 2011 was horrendous. Over 15,000 people were killed by the giant wave itself. The economic consequences of the reactor destruction were massive. The human consequences, in terms of death and evacuation, were also large. But the radiation deaths will likely be a number so small, compared with the tsunami deaths, that they should not be a central consideration in policy decisions.
The reactor at Fukushima wasn't designed to withstand a 9.0 earthquake or a 50-foot tsunami. Surrounding land was contaminated, and it will take years to recover. But it is remarkable how small the nuclear damage is compared with that of the earthquake and tsunami. The backup systems of the nuclear reactors in Japan (and in the U.S.) should be bolstered to make sure this never happens again. We should always learn from tragedy. But should the Fukushima accident be used as a reason for putting an end to nuclear power?Nothing can be made absolutely safe. Must we design nuclear reactors to withstand everything imaginable? What about an asteroid or comet impact? Or a nuclear war? No, of course not; the damage from the asteroid or the war would far exceed the tiny added damage from the radioactivity released by a damaged nuclear power plant.
It is remarkable that so much attention has been given to the radioactive release from Fukushima, considering that the direct death and destruction from the tsunami was enormously greater. Perhaps the reason for the focus on the reactor meltdown is that it is a solvable problem; in contrast, there is no plausible way to protect Japan from 50-foot tsunamis. Do we order a permanent evacuation of the coast to 20 miles inland? Do we try to build a 50-foot-high sea wall all around the eastern coast, including Tokyo Bay?
Looking back more than a year after the event, it is clear that the Fukushima reactor complex, though nowhere close to state-of-the-art, was adequately designed to contain radiation. New reactors can be made even safer, of course, but the bottom line is that Fukushima passed the test.
The great tragedy of the Fukushima accident is that Japan shut down all its nuclear reactors. Even though officials have now turned two back on, the hardships and economic disruptions induced by this policy will be enormous and will dwarf any danger from the reactors themselves."

Latest from SPEA on Candu strike
Latest from SPEA on Candu strike: Striking Candu Energy Engineers and Scientists to Picket Bay Street: http://www.spea.ca/ strike-update/ 265-august-9-2012-press-release -striking-candu-energy-enginee rs-and-scientists-to-picket-ba y-street.html
..."The Society of Professional Engineers and Associates (SPEA) is
holding an information picket this morning in front of the Toronto Stock
Exchange (TSX) to draw attention to SNC-Lavalin's disregard for
employees and shareholders.
Financial experts agree that SNC-Lavalin
is facing a "perfect storm": Financial scandal, labour disputes and the
search for a CEO, all attributable to a corporate culture that needs
fixing from top to bottom, said White. "We agree and they can start by
settling our labour dispute so we can return to work to deliver the best
nuclear technology and return value for shareholders."
"It is
shocking how SNC-Lavalin has conducted itself since they acquired Candu
Energy from the Federal Government," said Peter White, President of
SPEA. "Candu Energy has been one of the few bright spots for
SNC-Lavalin, which has been struggling with poor performance, leadership
issues and assorted allegations of financial wrongdoing."
According
to White, "Candu Energy has a bright future but current management
doesn't appreciate the opportunities and refuses to deal with employees
in a fair manner. This is resulting in staff leaving and creating lost
opportunities. "Since the federal government announced the sale of the
commercial division of Atomic Energy of Canada Limited (AECL) to
SNC-Lavalin in June of 2011, scientific and technical staff has been
reduced by approximately 25%. "For a technology company that relies
heavily on the skills of its workers this should concern shareholders,'
said White."

..."The birthplace of Canada's nuclear industry welcomed back the
community Saturday to celebrate six decades as a crown corporation.
For the first time in 12 years, Atomic Energy of Canada Limited opened
the doors of Chalk River Laboratories to the public presenting an
opportunity for area resident to not only celebrate its storied past but
gain insight into its future.
Despite overcast skies and the
occasional rain shower, over 2,000 people attended the open house which
presented an exhibition of 50 displays and lectures by professionals in
the nuclear energy field.
Joined by dignitaries, Dr. Robert Walker,
president and chief executive officer of Atomic Energy of Canada
Limited, formally thanked residents for supporting Renfrew County's
second largest employer noting that the work they are engaged in here
matters to Canadians.
"We've had a strong and deep history in
nuclear technology in this country and this has been the birthplace,"
said Dr. Walker. "It continues. That was the past and we're building
into the future."
While Chalk River Laboratories was forged out of
necessity to develop the atomic bomb during the closing days of the
Second World War, AECL was formally established as a crown corporation
in 1952. This year marks the 40th anniversary of the Nuclear Power
Demonstration, the nation's inaugural nuclear powered reactor,
generating electricity to the provincial grid for the first time. AECL
also commemorates the CANDU reactor at Pickering going online thus
producing more electricity than any nuclear power station in the world
at that time."

Happy 110th birthday Paul Dirac
Happy
110th birthday Paul Dirac! He is one of the icons of modern physics and
is perhaps best known for developing Dirac equation, a relativistic
wave equation to describe the spin and magnetic properties of the
electron, the foundation for modern condensed matter physics... The
Nobel Prize in Physics 1933 was awarded jointly to Erwin Schrödinger and
Paul Adrien Maurice Dirac "for the discovery of new productive forms of
atomic theory" this is a great summary of Diracss legendary work and
contribution in our understanding of universe: http://likelytool.com/ paul_dirac.htm... this is the link to Nobel Prize website: http://www.nobelprize.org/ nobel_prizes/physics/laureates/ 1933/dirac-bio.html
... and this is a famous quote by Dirac: "The fundamental laws
necessary for the mathematical treatment of a large part of physics and
the whole of chemistry are thus completely known, and the difficulty
lies only in the fact that application of these laws leads to equations
that are too complex to be solved."
A great biography book (THE
STRANGEST MAN: The Hidden Life of Paul Dirac, Mystic of the Atom. Basic
Books, 2009) written by Graham Farmelo in 2009 is reviewed here: http:// www.americanscientist.org/ bookshelf/pub/dr-strange
"In The Strangest Man, Graham Farmelo offers a highly readable and
sympathetic biography of the taciturn British physicist who can be said,
with little exaggeration, to have invented modern theoretical physics.
The book is a real achievement, alternately gripping and illuminating,
and the few flaws in the biographical integration are often due to the
recalcitrance of the subject himself.
It would have been far easier
to tackle only the physics, and surely that would have been enough.
Dirac’s life spanned most of the 20th century, and he was at the core of
its decisive scientific revolution: quantum mechanics. “At the core” is
an understatement. As Farmelo sagaciously puts it,"In his heyday,
between 1925 and 1933, he brought a uniquely clear vision to the
development of a new branch of science: the book of nature often seemed
to be open in front of him.""
This is also the link to an
interview with Graham Farmelo on NPR: "In a new biography, Graham
Farmelo digs deep into the archives and personal papers of a
little-known Nobel-winning physicist. Farmelo discusses The Strangest
Man: The Hidden Life of Paul Dirac, Mystic of the Atom and his theory
that Dirac may have been autistic." http://www.npr.org/ templates/story/ story.php?storyId=113435529

Neutron scattering explains how myoglobin can perform without water
Neat,
another evidence of the unique power of neutron scattering in helping
research in diverse areas of science, this time in biology: Neutron
scattering explains how myoglobin can perform without water: http://phys.org/news/2012-08-neutron-myoglobin.html
"Proteins do not need to be surrounded by water to carry out their
vital biological functions, according to scientists from the Institut de
Biologie Structurale (IBS) in Grenoble, the University of Bristol, the
Australian National University, the Institut Laue Langevin and the
Jülich Centre for Neutron Science.
In a new paper, published in the
Journal of the American Chemical Society, the team used a
state-of-the-art neutron scattering technique to demonstrate that when
myoglobin, an oxygen-binding protein found in the muscle tissue of
vertebrates, is enclosed in a sheath of surfactant molecules, it moves
in the same way as when it is surrounded by water. These motions are
essential if a protein is to perform its biological function, and their
findings make proteins a viable material for use in new wound dressings
or even as chemical gas sensors. Water is the natural environment for
soluble proteins and an integral part of their structures which allows
them to carry out their specific function. It had been perceived for
many years that proteins required water or another solvent in order to
function. But in 2010, the Bristol team proved that by grafting polymer
chains onto the protein surface, it was possible to produce solvent- and
water-free myoglobin liquids that could still perform their biological
roles. Scientists have now demonstrated that protein dynamics is the
reason why."

increase between 44 percent and 99 percent by 2035, the International
Atomic Energy Agency and the Organization for Economic Cooperation and
Development Nuclear Energy Agency said in their joint biannual report on
uranium resources, released this week.
Japan's decision to shut
down all but two of its nuclear reactors in the wake of the nuclear
accident at Fukushima Daiichi last year played in to Germany's decision
to phase out nuclear by 2022, but has apparently not slowed plans in
other parts of Asia. Nuclear energy will see the sharpest expansion in
China, India, and South Korea, the agencies said in a release, as well
as in Russia."
