Many pitfalls in adopting Small Modular Nuclear Reactors – not a viable solution to climate change

‘Many issues’ with modular nuclear reactors says environmental lawyer, https://www.cbc.ca/news/canada/new-brunswick/many-issues-modular-nuclear-1.5381804

Three premiers have agreed to work together to develop the technology, Jordan Gill · CBC News   Dec 03, 2019  Modular nuclear reactors may not be a cure for the nation’s carbon woes, an environmental lawyer said in reaction to an idea floated by three premiers.

Theresa McClenaghan, executive director of the Canadian Environmental Law Association, said the technology surrounding small reactors has numerous pitfalls, especially when compared with other renewable energy technology.

This comes after New Brunswick Premier Blaine Higgs, Saskatchewan Premier Scott Moe and Ontario Premier Doug Ford agreed to work together to develop the technology.

Small modular reactors are easy to construct, are safer than large reactors and are regarded as cleaner energy than coal, the premiers say. They can be small enough to fit in a school gym.  Designs have been submitted to Canada’s nuclear regulator for review as part of a pre-licensing process.

The premiers say the smaller reactors would help Canada reach its carbon reduction targets but McClenaghan, legal counsel for the environmental group, disagrees.

“I don’t think it is the answer,” said McClenaghan. “I don’t think it’s a viable solution to climate change.”

McClenaghan said the technology behind modular reactors is still in the development stage and needs years of work before it can be used on a wide scale.

“There are many issues still with the technology,” said McClenaghan. “And for climate change, the risks are so pervasive and the time scale is so short that we need to deploy the solutions we already know about like renewables and conservation.”

Waste, security concerns: lawyer

While nuclear power is considered a low-carbon method of producing electricity, McClenaghan said the waste that it creates brings its own environmental concerns.

“You’re still creating radioactive waste,” said McClenaghan.

“We don’t even have a solution to nuclear fuel waste yet in Canada and the existing plans are not taking into account these possibilities.”

McClenanghan believes there are national security risks with the plan as well.  She said having more reactors, especially if they’re in rural areas, means there’s a greater chance that waste or fuel from the reactors could be stolen for nefarious purposes.

“You’d be scattering radioactive materials, potentially attractive to diversion, much further across the country,” said the environmental lawyer.

COP25: youth ‘leadership’ contrasts with government inaction, says UN chief

COP25: youth ‘leadership’ contrasts with government inaction, says UN chief,  Ahead of Madrid climate change conference António Guterres says political will missing, Guardian,  Fiona Harvey Environment correspondent, 2 Dec 19, António Guterres, the United Nations secretary general, contrasted the “leadership” and “mobilisation” shown by the world’s youth on the climate emergency with the lack of action by governments, which were failing to keep up with the urgency of the problem despite increasing signs that the climate was reaching breakdown.

Before the start of a critical conference on the climate crisis on Monday, he said the world had the technical and economic means to halt climate chaos, but what was missing was political will.

“The technologies that are necessary to make this possible are already available. Signals of hope are multiplying. Public opinion is waking up everywhere. Young people are showing remarkable leadership and mobilisation. [But we need] political will to put a price on carbon, political will to stop subsidies on fossil fuels [and start] taxing pollution instead of people.”

Guterres called for further investment from rich countries and support for poor nations to make the changes needed to reduce greenhouse gas emissions and cope with the impacts of global heating. Amid rising temperatures, wildfires, heatwaves, droughts and floods, the danger signals were clear and must be acted on without further delay, he said…..

The countries most at risk of deluge from climate chaos have issued an impassioned plea to the industrialised world ahead of crucial negotiations on the Paris agreement that start on Monday in Madrid.

“We see [these talks] as the last opportunity to take decisive action,” Janine Felson, deputy chair of the Alliance of Small Island States (AOSIS) told the Guardian.

“Anything short of vastly greater commitment to emission reduction, a new climate finance goal and tangible support for disaster risk reduction will signal a willingness to accept catastrophe.” https://www.theguardian.com/science/2019/dec/01/island-states-want-decisive-action-to-prevent-inundation

On climate policy – “To err on the side of danger is a stupid thing to do.” 

One website tracking climate emergency declarations says 1,195 jurisdictions in 25 countries, representing 454 million people, have already voted on the [climate] emergency.

This week the European parliament joined them, as did Ballina shire council in northern New South Wales, the 76th local government authority in Australia to make the declaration.

In the Nature article, the scientists highlight nine “tipping points” that, if crossed, become almost impossible to stop. At least five are already “active”.

“To err on the side of danger is a stupid thing to do.”

Formula for climate emergency shows if ‘reaction time is longer than intervention time left’ then ‘we have lost control’ Graham Readfearn

When is an emergency really an emergency?

If you’re the captain of the Titanic, approaching a giant iceberg with the potential to sink your ship becomes an emergency only when you realise you might not have enough time to steer a safe course.

And so it is, says Prof Hans Joachim Schellnhuber, when it comes to the climate emergency.

Rather than being something abstract and open to interpretation, Schellnhuber says the climate emergency is something with clear and calculable risks that you could put into a formula. And so he wrote one. Continue reading

Prominent Americans to wage ‘World War Zero’ against climate change

John Kerry Launches Star-Studded Climate Coalition, NYT, By Lisa Friedman, Nov. 30, 2019 WASHINGTON — John Kerry, the former senator and secretary of state, has formed a new bipartisan coalition of world leaders, military brass and Hollywood celebrities to push for public action to combat climate change.

The name, World War Zero, is supposed to evoke both the national security threat posed by the earth’s warming and the type of wartime mobilization that Mr. Kerry argued would be needed to stop the rise in carbon emissions before 2050.

The star-studded group is supposed to win over those skeptical of the policies that would be needed to accomplish that.

Former presidents Bill Clinton and Jimmy Carter are part of the effort. Moderate Republican lawmakers like Arnold Schwarzenegger, the former governor of California, and John Kasich, the former governor of Ohio, are on the list. Stars like Leonardo DiCaprio, Sting and Ashton Kutcher round out the roster of more than 60 founding members.

“We’re going to try to reach millions of people, Americans and people in other parts of the world, in order to mobilize an army of people who are going to demand action now on climate change sufficient to meet the challenge,” Mr. Kerry said in an interview.

The launch of the new group on Sunday comes as diplomats gather in Madrid on Monday for global climate negotiations aimed at strengthening the 2015 Paris Agreement, from which President Trump has vowed to withdraw next year. Earlier this week the United Nations found that the world’s richest countries, responsible for emitting more than three-fourths of planet-warming pollution, are not doing enough to keep Earth’s temperature from rising to dangerously high levels.

U.S. Government effectively boycotting COP25 climate conference

US will ‘protect its interests’ at COP25 climate conference No senior members of Donald Trump’s administration will attend COP25.  https://www.sbs.com.au/news/us-will-protect-its-interests-at-cop25-climate-conference   2 Dec 19, The US will send a diplomatic team but no senior members of Donald Trump’s administration to a global climate change conference starting in Spain on Monday, according to a statement.However, in an effort to raise the US profile in Madrid, House speaker Nancy Pelosi will led a 15-member congressional delegation to “reaffirm the commitment of the American people to combating the climate crisis”.

The US, at Mr Trump’s direction, is withdrawing from the Paris climate accord, which set a goal of limiting global temperature rises to well within two degrees Celsius from pre-industrial levels.

Spain stepped in to host the COP25 meeting, which seeks to boost commitments to fight climate change, after Chile pulled out due to civil unrest.

“The United States will continue to participate in ongoing climate change negotiations and meetings – such as COP25 – to ensure a level playing field that protects US interests,” the US State Department said Saturday.

The US team will be headed by ambassador Marcia Bernicat, principal deputy assistant secretary of state for oceans and international environmental and scientific affairs.

Ms Pelosi, calling climate change “the existential threat of our time,” announced a delegation of Democrats drawn from both the House and the Senate, with no members of Mr Trump’s Republican party.

The president has cast the Paris climate accord as elitist and unfair to the US, saying when announcing his decision to withdraw that he was “elected to represent the citizens of Pittsburgh, not Paris”.

But scientists say the accord is vital to check the worst damage from global warming, such as increasing droughts, rising floods and intensifying storms.

The US is the world’s second biggest emitter of greenhouse gases after China, and is the only country to pull out of the Paris agreement.

The final US withdrawal from the landmark accord is scheduled for 4 November, 2020, a day after the next presidential election.

Several Democratic presidential aspirants have said that, if elected, they would immediately return to the agreement.

Short term fixes for staggeringly long lasting nuclear wastes

The Staggering Timescales Of Nuclear Waste Disposal,  Christine Ro  https://www.forbes.com/sites/christinero/2019/11/26/the-staggering-timescales-of-nuclear-waste-disposal/#621facec29cf

High-level nuclear waste consists largely of spent fuel from nuclear reactors. Though it makes up a small proportion of overall waste volumes, it accounts for the majority of radioactivity. This most potent form of nuclear waste, according to some, needs to be safely stored for up to a million years. Yes, 1 million years – in other words, a far longer stretch of time than the period since Neanderthals cropped up. This is an estimate of the length of time needed to ensure radioactive decay.

Yet existing and planned nuclear waste sites operate on much shorter timeframes: often 10,000 or 100,000 years. These are still such unimaginably vast lengths of time that regulatory authorities decide on them, in part, based on how long ice ages are expected to last. To some extent all of these figures are little better than educated guesses.

They’re also such mind-bogglingly long periods that in 1981, the US Department of Energy established the Human Interference Task Force to devise ways to warn future generations of the dangerous contents of nuclear repositories. This was a challenging task then, and nuclear semiotics remains the stuff of science fiction. Written language has only existed for about 5,500 years, so there’s no guarantee that Earth’s inhabitants, tens of thousands of years from now, would understand any of the writing systems currently in use. The meanings of visual signs also drift over time. The more whimsical “ray cat solution,” of genetically engineering cats to glow in the presence of radioactive material, is even less reliable.

Even stopping nuclear power operations is a necessarily drawn-out process. Decommissioning a single nuclear reactor typically takes about 20 years. Most countries grappling with nuclear waste are planning for at least 40 to 60 years just to implement their repository programs.

After brief flirtations with amusingly bad ideas including shooting nuclear waste into space, the consensus among nuclear scientists is that the best option for dealing with high-level nuclear waste is deep geological disposal. One of the International Atomic Energy Agency’s conditions for such a geological site is low groundwater content, which has been stable for at least tens of thousands of years, and geological stability, over millions of years. Thus, Japan, with its seismic instability, is unlikely to have any suitable candidates for deep geological disposal.

Like many countries, Japan is relying on interim storage of high-level waste while hoping that longer-term solutions will present themselves eventually. In fact, no country even has an operational deep geological repository for spent nuclear fuel. (The US has a deep disposal site in New Mexico for “transuranic” waste from nuclear weapons, which is long-lived and intermediate-level waste whose elements have higher numbers than uranium in the periodic table.)

It’s challenging to find a site that ticks all of the geological boxes (including relatively impermeable material with little risk of water infiltration), and that isn’t politically controversial. To take two notable examples, communities in Nevada, US and Bure, France have hotly opposed plans to establish repositories. Given the history of environmental justice globally, it’s likely that any future locations approved for nuclear waste dumps will be found in poor areas.

Only one country, Finland, is even building a permanent spent-fuel repository. Even in Finland, however, it’s estimated that a license won’t be issued until 2024. Similar licenses for other European countries scouting out possible locations likely wouldn’t be available until 2050 in Germany and 2065 in the Czech Republic. And these countries are outnumbered by those that don’t even have an estimated timeframe for licensing, as they’re so far back in the process of searching for a site.

Strategies remain worryingly short-term, on a nuclear timescale. Chernobyl’s destroyed reactor no. 4, for instance, was moved in July 2019 into a massive steel and concrete “sarcophagus” that will only last 100 years. Not only will containers like this one fall short of the timescales needed for sufficient storage, but no country has allotted enough funds to cover nuclear waste disposal. In France and the US, according to the recently published World Nuclear Waste Report, the funding allocation only covers a third of the estimated costs. And the cost estimates that do exist rarely extend beyond several decades.

Essentially, we’re hoping that things will work out once future generations develop better technologies and find more funds to manage nuclear waste. It’s one of the most striking examples of the dangers of short-term thinking.Check out my website.

WHAT TO EXPECT FROM THE UN’S COP 25 CLIMATE CHANGE CONFERENCE

WHAT TO EXPECT FROM THE UN’S COP 25 CLIMATE CHANGE CONFERENCE,  https://ensia.com/notable/cop-25-un-climate-talks/    Andrew Urevig @aurevig   November 26, 2019 — In 2015, 195 countries adopted an international treaty aiming to limit global warming to less than 2 °C (3.6 °F) above average preindustrial temperatures in order to avert the worst of Earth’s climate emergency.

How exactly will these countries implement that treaty, the Paris agreement? That’s a key question for the thousands of people set to attend the COP 25 negotiations, the 25th annual Conference of Parties to the United Nations Framework Convention on Climate Change. Despite a last-minute change of location from Chile to Spain, the talks are still slated for December 2–13.

Representatives of countries around the world are preparing to negotiate rules for international carbon markets, finalize details on climate finance and ready the world for the crucial next decade of action on the climate crisis. Chilean environmental minister Carolina Schmidt will preside over the negotiations.

Double Counting Strikes Back

According to Schmidt, “COP 25 will be the COP of implementation.” The main goal is to fill in the legal and technical details of the Paris agreement. That work began at COP 24, which was held last year in Poland.

Left unresolved last year were the rules for voluntary carbon emissions markets, which would let nations meet their pledged emissions cuts by trading reductions with other countries. In a June interview, Schmidt said that these rules, covered under Article 6 of the Paris treaty, would be a major focus of COP25.

Finishing the work of COP 24, this year’s negotiations should finalize the details of the Paris agreement. But consensus could be difficult to reach. During the last climate talks, according to Carbon Brief, draft rules for the carbon markets would have prohibited double counting of emissions, a scenario in which reductions would be counted by both the country that achieved them and the country purchasing those reductions as emissions offsets. But the delegation from Brazil rejected that prohibition, pushing the conversation off to this year.

Other Issues

Other issues will be on the table, too. Countries at COP 25 will discuss details for climate finance to support countries designated as developing as they adapt to climate change and mitigate their carbon emissions.

Outside the halls of power, COP 25 could see street demonstrations and other protests. Last year’s talks coincided with protests worldwide, including 3,000 who marched in Katowice, Poland, where the talks were held.

U.S. diplomats will be among the negotiators — but potentially for the last time. President Donald Trump notified the U.N. Framework Convention on Climate Change (UNFCCC) on Nov. 4, 2019, that the U.S. would withdraw from the Paris agreement. The U.S. is scheduled be officially out of the deal by Nov. 4, 2020, less than a week before COP 26 will begin in Glasgow, Scotland. A U.S. delegation will still be invited to attend the conference — but not to negotiate, in an official capacity, the future of the Paris accord.

Pope Francis, in Japan, Warns of ‘Selfish Decisions’ on Nuclear Energy

November 28, 2019 Posted by | General News | Leave a comment

Catholic doctrine; the use and even the possession of nuclear is immoral

Pope Francis: not using or possessing nuclear arms will be added to the Catechism, Catholic Outlook,27 November 2019 During the in-flight press conference aboard the plane bringing him back to Rome from Japan, Pope Francis answers journalists’ questions on a variety of issues: from the immoral use and possession of atomic weapons, to the financial investigation inside the Vatican.

“The use of nuclear weapons is immoral, which is why it must be added to the Catechism of the Catholic Church. Not only their use, but also possessing them: because an accident or the madness of some government leader, one person’s madness can destroy humanity.”

In addition to repeating this strong message pronounced at Hiroshima, Pope Francis responded to many questions posed to him by the journalists during the flight bringing them back to Rome from Japan.

Now follows an unofficial translation of the in-flight press conference……….

Hiroshima was a real human catechesis on cruelty. I could not visit the Hiroshima museum because time did not permit, because it was a difficult day. But they say it’s terrible. There are letters from Heads of State, Generals explaining how a greater disaster could be produced. The experience was much more touching for me. And there I reiterated that the use of nuclear weapons is immoral, that is why it must be added to the Catechism of the Catholic Church. Not only their use, but also possessing them: because an accident or the madness of some government leader, one person’s madness can destroy humanity. The words of Einstein come to mind: ‘The Fourth World War will be fought with sticks and stones.’ ” …….

The ugly hypocrisy of the ‘arms trade’. Christian countries, European countries that talk about peace and live off weapons. This is hypocrisy, a word from the Gospels: Jesus said it in Matthew, Chapter 23. We have to stop this hypocrisy. It takes courage to say: “I can’t talk about peace, because my economy earns so much through arms sales’”. These are all things we need to say, without insulting and vilifying any country, but speaking as brothers and sisters, for the sake of human fraternity: we must stop because this is a terrible thing. “………… https://catholicoutlook.org/pope-francis-not-using-or-possessing-nuclear-arms-will-be-added-to-the-catechism/
