Climate change will kill nuclear power – theme for August 18

This month the world is experiencing unprecedented heatwaves right across Northern Hemisphere countries. And this pattern is predicted to be repeated in future years.  It’s already having a detrimental effect on the nuclear power industry.  France’s nuclear reactors are cutting back production, with cooling water restrictions due to raised river temperatures. Finland’s reactors have had to cut back, due to sea water being too warm for cooling reactors, and might need to be shut down.

That’s just one aspect of the the way in which climate change is going to kill nuclear power.

Nuclear power stations must have lots of cool water. They are a liability in times of drought, and of high temperatures. Indeed, the whole industry is, with uranium mining requiring much water, too.

Wildfires pose a particular threat to all nuclear facilities.

Most nuclear reactors are located on the coast, or near rivers, where they can be vulnerable to flooding –   and this danger increases as climate change brings sea level rise, and storm surges..

Apart from the increasing costs of nuclear construction, maintenance, and final dismantling, clean-up and waste disposal, the nuclear industry is facing more costs in increasingly desperate efforts to ward off the damage that climate change will do to it.

Climate change against nuclear power theme for August 2018

Nuclear power and sea level rise – All reactors on sea coasts endangered by sea level rise Over the next hundred years there will be significant sea rises, one meter or more, and many closed nuclear reactor sites could be flooded, including the stored nuclear waste. That could contaminate much of the coast lines for decades.

As water becomes scarcer, and more expensive, nuclear power becomes a very uneconomic way to use it.

As temperatures rise, nuclear reactors will more and more often be forced to shut down – adding to the already well known diseconomics of nuclear power

Climate change ensures that there’ll be more heat waves

It’s a savage summer in the Northern Hemisphere – and climate change is slashing the odds of more heatwaves https://theconversation.com/its-a-savage-summer-in-the-northern-hemisphere-and-climate-change-is-slashing-the-odds-of-more-heatwaves-100582

In Australia we know about sweltering summer heat. We all remember the images of burned koala pawscollapsing tennis players and, far more seriously, the tragic events of Black Saturday.

Aussies may scoff at Britain’s idea of a heatwave, but this time it’s the real deal and it’s no laughing matter.

Extreme heat has hit locations throughout the Northern Hemisphere, in places as far apart as MontrealGlasgowTokyo and Lapland. In the past few weeks heat records have tumbled in a wide range of places, most notably:

Heat has not been the only problem. Much of northern Europe is experiencing a very persistent drought, with little to no measurable rainfall in months. This has caused the normally lush green fields of England and other European countries to turn brown and even reveal previously hidden archaeological monuments.
 

There have also been major wildfires in northern EnglandSweden and, most recently and devastatingly, Greece. The Greek wildfires came off the back of a very dry winter and spring.

What’s behind the widespread extreme heat?

The jet stream, a high-altitude band of air that pushes weather systems around at lower altitudes, has been weaker than normal. It has also been positioned unusually far to the north, particularly over Europe. This has kept the low-pressure systems that often drive wind and rain over northern Europe at bay.

The jet stream has remained locked in roughly the same position over the Atlantic Ocean and northern Europe for the past couple of months. This has meant that the same weather types have remained over the same locations most of the time.

Weather is typically more transient than it has been recently. Even when we do have blocking high-pressure systems associated with high temperatures in northern Europe, they don’t normally linger as long as this.

Is it driven by climate change?

Although climatologists have made great strides in recent years in the field of event attribution – identifying the human climate fingerprint on particular extreme weather events – it is hard to quantify the role of climate change in an event that is still unfolding.

Until the final numbers are in we won’t be able to tell just how much climate change has altered the likelihood or intensity of these particular heat extremes.

Having said that, we can use past analyses of extreme heat events, together with future climate change projections, to infer whether climate change is playing a role in these events.

We also know that increasing numbers of hot temperature records are being set, and that the increased probability of hot temperature records can indeed be attributed to the human influence on the climate.

In Europe especially, there is already a large body of literature that has looked at the role of human-caused climate change in heat extremes. In fact, the very first event attribution study, led by Peter Stott from the UK Met Office, found that human-caused climate change had at least doubled the likelihood of the infamous European heatwave of 2003.

For all manner of heat extremes in Europe and elsewhere, including in Japan, a clear and discernible link with climate change has been made.

Research has also shown that heat extremes similar to those witnessed over the past month or two are expected to become more common as global temperatures continue to climb. The world has so far had around 1℃ of global warming above pre-industrial levels, but at the global warming limits proposed in the Paris climate agreement, hot summers like that of 2003 in central Europe would be a common occurrence.

At 2℃ of global warming, the higher of the two Paris targets, 2003-like hot summers would very likely happen in most years.

Similarly, we know that heat exposure and heat-induced deaths in Europe will increase with global warming, even if we can limit this warming to the levels agreed in Paris.

But summers have always been hot, haven’t they?

For most parts of the world summers have got warmer, and the hottest summer on record is relatively recent – such as 2003 in parts of central Europe and 2010 in much of eastern Europe. One exception is central England, where the hottest summer remains 1976, although it may be challenged this year.

While extreme hot summers and heatwaves did happen in the past, they were less common. One big difference as far as England is concerned is that its extreme 1976 heatwave was a global outlier, whereas this year’s isn’t.

In 1976 northwestern Europe had higher temperature anomalies than almost anywhere else on the globe. In June 2018 the same region was unusually warm, but so was most of the rest of the Northern Hemisphere.

So while the persistent weather patterns are driving much of the extreme heat we’re seeing across the Northern Hemisphere, we know that human-caused climate change is nudging the temperatures up and increasing the odds of new heat extremes.

France’s nuclear power stations affected by extreme heat – causing restricted output

S&P 24th July 2018 , France’s EDF expects nuclear-fired power production at its Bugey and
Saint-Alban power stations to be curtailed “due to extreme temperature forecast,” the utility said Tuesday. On grid operator RTE’s website, EDF said environmental issues are limiting “some” nuclear production availability in the country, starting Saturday. EDF did not give details on the exact impact of the output restrictions. The two nuclear power stations have a combined capacity of over 6 GW. Environmental issues have already resulted in weekend outages at EDF’s Bugey-3 reactor on the river Rhone.

Hot weather conditions previously have led to cooling water restrictions due to raised river temperatures. According to forecaster MeteoFrance, temperatures should remain above seasonal average, or around 2 degrees Celsius above norms over the weekend.

Japan has amassed enough plutonium to make 6,000 nuclear bombs

Economist 25th July 2018 Japan has now amassed 47 tonnes of plutonium, enough to make 6,000 bombs.
What is Japan doing with so much plutonium? Plutonium is at the heart of
Japan’s tarnished dream of energy independence. Spent fuel from nuclear
reactors can be reprocessed to extract plutonium, which is then recycled
into mixed oxide, or MOX, fuel. This was intended for use in Japan’s
reactors but most of its nuclear power plants have been offline since the
2011 Fukushima disaster.

Tougher safety checks have failed to reassure the
nuclear-phobic public that the reactors can be restarted. And Japan’s
nuclear-energy fleet is ageing. Taro Kono, Japan’s foreign minister, has
admitted that this situation is “extremely unstable”.

Japan’s status as a plutonium superpower is increasingly under scrutiny. The government
says it has no intention of building a bomb. But China and other countries
question how long it can be allowed to stockpile plutonium. Analysts worry
about a competitive build-up of plutonium in Asia.

Moreover Japan’s stock, which is weapons-grade, is reprocessed and stored in France and
Britain. It is moved across the world in heavily armed convoys. America
says those shipments and the storage of plutonium in civilian sites present
a potential threat to non-proliferation goals: they could be redirected to
make weapons, or targeted by terrorists. It is nudging its ally to start
reducing the hoard.

Warming sea water affecting cooling systems in Finland’s nuclear power station

Warm sea water in Finland reduces power from Loviisa nuclear plant https://www.reuters.com/article/us-finland-nuclear-fortum-oyj/warm-sea-water-in-finland-reduces-power-from-loviisa-nuclear-plant-idUSKBN1KF2COLefteris Karagiannopoulos 26 July 18  OSLO (Reuters) – Finland’s Loviisa power plant, consisting of two reactors with a combined capacity of 1 gigawatt, had to reduce power by 170 megawatts on Wednesday as the sea water that is used to cool the reactors had become too warm, operator Fortum said.

Because of the very warm temperatures the Nordic region is currently experiencing, the sea water that is collected to cool the Loviisa reactors is warmer and the water released is also warmer, at 32 degrees Celsius on Wednesday.

Releasing hot water back to the sea after cooling the reactors could be a hazard and if it exceeds 34 degrees Fortum said the reactors must be shut down due to regulations.

“We decreased power by 170 megawatts for a bit less than two hours. The sea water that cools the reactors was at 24 degrees, which is warmer than usual,” Fortum’s chief of operations in the plant, Timo Eurasto, told Reuters.

Such a rare occurrence may happen again in the next days because of the unusually warm temperatures, he said, adding that there was no danger to people, the plant, or the environment.

“High sea water temperature may indeed reduce the efficiency of the cooling systems of the plant. This is compensated by reducing or shutting down the reactor power,” said Nina Lahtinen, nuclear safety section head at Finland’s regulator STUK.

In Germany traders warned last week that higher temperatures in August may create cooling issues for the country’s reactors, with E.ON subsidiary PreussenElektra cutting output slightly from two units.

Sweden’s nuclear energy regulator SSM, told Reuters on Tuesday that power production at the Forsmark nuclear plant has also been reduced “by a few percentage points” due to cooling issues.

Last time Fortum had to reduce power in its reactors due to warmer-than-usual cooling water was seven years ago, said Loviisa plant’s Eurasto.

Unusually warm and dry weather in the Nordics led temperatures to record highs this summer, affecting water levels at the reservoirs that feed Norway and Sweden with hydropower, causing prices to spike as a result.

South Carolina Nuclear Plant leaking radioactive uranium into ground below

Uranium Leaked Through Floor of South Carolina Westinghouse Nuclear Plant https://www.ecowatch.com/south-carolina-nuclear-plant-leak-2590122072.html 26 July 18 nuclear plant in Richmond County, South Carolina with a history of contaminating groundwater has leaked radioactive uranium into the soil below the plant, The State reported Tuesday.

South Carolina Department of Health and Environmental Control (DHEC) officials said there was no reason to believe this leak left the the site of the Westinghouse plant or posed a threat to public drinking water, but state senator Darrell Jackson is calling for a public meeting to discuss the leak and other historic issues at the plant, The State further reported Wednesday.

“This is very disturbing,” Jackson said. “This is one of the fears that those of us who grew up in that area, and lived in that area, have always talked about. I’m asking DHEC to get to Westinghouse officials and let’s have a public meeting, not just with elected officials, but we need citizens there also.”

The company informed the U.S. Nuclear Regulatory Commission (NRC) of the leak July 12, which came through a hole in a part of the plant where acid is used. The hole was three inches and extended six feet into the ground, the NRC told The State.

The NRC found uranium levels in the soil of 4,000 parts per million, more than 1,000 times higher than average for soil.

“That’s a lot, oh yeah,” U.S. Geological Survey scientist Frank Chapelle told The State.

The company has covered the hole with a metal plate and said it would not use the area until it was completely repaired.

The DHEC said they were still testing the groundwater on the site to see if it was contaminated, but said the plant itself was far enough away from public drinking water that it shouldn’t cause a problem.

“Based on existing information, there is no threat to the public from this recent release or from historical groundwater contamination at this secured site as there is no exposure risk to the general public,” DHEC spokesperson Tommy Crosby told The State.

But Jackson was not reassured.

“What we don’t know is what kind of impact that’s going to have 20 years from now on the groundwater, this drip, drip, drip,” Jackson said. “I don’t know of too many people too receptive to living in the area when they know the groundwater is contaminated.”

DHEC spokesperson Cristi Moore said the agency would consider the senator’s request for a meeting.

This isn’t the first time safety concerns have surrounded the Westinghouse plant.

Part of the plant had to shut down two years ago because of uranium found accumulating in an air pollutiondevice, The Associated Press reported. It was also cited by the federal government this year for failing to plan adequately for a potential radiation burst.

Groundwater below the plant has also been found to be contaminated with nitrate since 1984. While clean up efforts were made, the nitrate was not entirely removed, The State reported.

The leak comes as the Trump administration has promised to assist unprofitable nuclear and coal plants. Its most recent plan, reported in June, would require that grid operators buy power from struggling plants for the sake of national security.

USA Unlikely To See New Nuclear Power Anytime Soon

Study: US Unlikely To See New Nuclear Power Anytime Soon, WABE   Nuclear power doesn’t have much of a future in the U.S., according to a recent paperthat says the country is unlikely to see many new reactors in coming decades, unless there are major policy changes.

That means the only nuclear reactors under construction in the country right now, which are here in Georgia, could be the last ones built in the U.S. for years.

A fifth of the nation’s electricity comes from nuclear power, but the number of plants is shrinking. Some have already closed, and others are scheduled to. Low natural gas prices have made building new nuclear reactors less competitive, and renewable energy is getting more competitive………..The findings in the paper weren’t a surprise to Sara Barczak, regional advocacy director with the Southern Alliance for Clean Energy, a group that has been critical of the nuclear expansion at Plant Vogtle in Georgia.

She said years ago, there were more than 15 new reactors planned in the Southeast, but now there are only the two at Vogtle going forward. A similar project in South Carolina was canceled last year.

“The authors took a hard look at the realities … coming to the conclusion that it’s extremely costly, it takes quite a long time for these things to come online if they do, ever,” she said.

And the idea that nuclear power faces an uncertain future isn’t bad news to everyone.

“Nuclear energy is too expensive and too dangerous, and uses a ton of water,” said Colleen Kiernan, executive director of the group Georgia Conservation Voters.

Instead, she supports investing more in energy efficiency, renewable power and battery storage.

The two nuclear reactors under construction at Plant Vogtle, near Augusta, are years behind schedule and billions of dollars over budget. Last year, when the future of that project was up in the air, there were questions of whether it was really needed in Georgia. ….https://www.wabe.org/study-us-unlikely-to-see-new-nuclear-power-anytime-soon/

Electricite de France wants pension funds to cough up for building Sizewell nuclear project

EDF Wooing Pension Funds to Finance Sizewell U.K. Nuclear Plant, Bloomberg, By Rachel Morison 12 pension funds interested in backing plant in East Anglia  Plant would lower nuclear costs by copying design of Hinkley

The developer of Britain’s first nuclear power station in more than three decades has approached 12 pension funds about helping finance a sister plant on the other side of the country.

Electricite de France SA is working on ways to pay for its Sizewell C project in East Anglia that will make it cheaper than the Hinkley Point C nuclear plant it’s building on the coast of Southwest England. Hinkley has been a lightning rod for controversy since the government pledged to pay 92.50 pounds ($122) a megawatt-hour for its power, more than 60 percent more than the latest offshore wind farms……..

Prime Minister Theresa May’s government has estimated it needs to draw in 100 billion pounds within the next decade to upgrade power grids and replace aging generation plants as the bulk of Britain’s nuclear fleet finishes its life in service. ……..https://www.bloomberg.com/news/articles/2018-07-26/edf-wooing-pension-funds-to-finance-sizewell-u-k-nuclear-plant

British tax-payers’ liability in the event of a nuclear accident at Wylfa

Government outlines public liability at Wylfa nuclear plant https://www.newcivilengineer.com/latest/government-outlines-public-liability-at-wylfa-nuclear-plant/10033570.article 26 JULY, 2018 BY JESS CLARK  Government has outlined public liability in the event of an accident at Wylfa nuclear power station, amid concerns that taxpayers will be left to pick up the bill.

Nuclear operators must have insurance, energy and clean growth minister Claire Perry told parliament, and any costs more than €1.5bn (£1.33bn) would be “met at parliament’s discretion”.

The Westminster Hall debate followed a report in the Times  that claimed Japanese company Hitachi would not pay for any accidents at the proposed plant in Anglesey, north Wales.

Energy and clean growth minister Claire Perry said: “There were some questions about liability in the event of an accident. I am happy to say that the last significant incident was the Windscale fire in 1957, and we are light years away from that plant in terms of nuclear operating technology and the safety regime that we operate.

“The Nuclear Installations Act 1965 makes the insurance that I mentioned a requirement, without which operators cannot operate. As the hon. Member for Southampton, Test mentioned, we also have legislation based on the Paris and Brussels conventions.

If the total cost of claims ever exceeded €1.2 billion, a further €300 million would be provided by all contracting parties to the Brussels supplementary convention. Any further claims above that total would be met at Parliament’s discretion.”

Alan Brown MP said: “It marks a departure from the “polluter pays” principle. It is critical that the UK Government do not sign up to any such crazy proposals.”The government is in “commercial negotiations” with Hitachi over the plans, and will take a £5bn stake in the project.
