“Timeless, masterful. . .A stomach-clenching, multi-perspective, ticking-clock, geopolitical thriller. Jacobsen expertly delivers a madman’s portrait of Armageddon, one made all the more impactful by the thought that it could literally occur at any moment. Almost novel-like in its presentation, Nuclear War: A Scenario represents the equivalent of an existential gut punch, a sickening and necessary reminder of how fragile every 21st century convenience becomes in the face of a blinding flash of light and near-instantaneous shockwave. Exhaustively researched and featuring interviews with professionals who truly understand just how close we continue to creep toward thermonuclear annihilation Nuclear War: A Scenario should be required reading for everyone alive today, especially for the politicians and policymakers who literally hold the precarious fate of our species in their hands.” — Forbes

Small modular reactors (SMRs) have been the subject of endless hype in recent years but in fact, no SMRs have ever been built, none are being built now and in all likelihood none will ever be built because of the prohibitive costs. SMRs are defined as reactors with a capacity of 300 megawatts (MW) or less with serial factory production of reactor components (or ‘modules’). No SMRs have been built, but dozens of small (<300 MW) power reactors have been built in numerous countries, without factory production of reactor components.

The role of health professionals In January 2023, the science and security board of the Bulletin of the Atomic Scientists moved the hands of the doomsday clock forward to 90 seconds before midnight, reflecting the growing risk of nuclear war.1 In August 2022, the UN secretary general, António Guterres, warned that the world is now in “a time of nuclear danger not seen since the height of the Cold War.”2 The danger has been underlined by growing tensions between many nuclear armed states.13 As editors of health and medical journals worldwide, we call on health professionals to alert the public and our leaders to this major danger to public health and the essential life support systems of the planet—and urge action to prevent it. Current nuclear arms control and non-proliferation efforts are inadequate to protect the world’s population against the threat of nuclear war by design, error, or miscalculation. The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) commits each of the 190 participating nations
There has been a strong push to promote increased investments in new nuclear power as a strategy to decarbonize economies, especially in the European Union (EU) and the United States (US). The evidence base for these initiatives is poor. Investments in new nuclear power plants are bad for the climate due to high costs and long construction times. Given the urgency of climate change mitigation, which requires reducing emissions from the EU electricity grid to almost zero in the 2030s (Pietzcker et al.1), preference should be given to the cheapest technology that can be deployed fastest. On both costs and speed, renewable energy sources beat nuclear. Every euro invested in new nuclear plants thus delays decarbonization compared to investments in renewable power. In a decarbonizing world, delays increase CO2 emissions. Our thoughts focus on new nuclear power plants (not phasing out existing plants) in the US and Europe. In Europe, new nuclear power plants are planned or seriously discussed in France, Czechia, Hu

Fearful that the Able Archer 83 exercise was a cover for a NATO nuclear strike, the U.S.S.R. readied its own weapons for launch
Land-based nuclear weapons are world-ending accident waiting to happen, and completely superfluous to a reliable deterrent.
If the system can’t contact military leaders, it checks for signs of a nuclear strike. Should its computers determine that an attack occurred, it would automatically launch all remaining Soviet weapons at targets across the northern hemisphere. As in the film, the Soviet Union long kept Dead Hand completely secret, eliminating any strategic benefit, and rendering it a pointless menace to humanity. You might think the United States would have a more sensible nuclear launch policy. You’d be wrong.

On Sept. 10, 1969, six and a half miles south of Rulison, Colorado, a 40-kiloton nuclear bomb exploded in the subterranean depths of the Piceance Basin. The device, more than twice as powerful as the weapon at Hiroshima and with muscle equivalent to 40,000 tons of TNT, was an unorthodox tool in a grand experiment to free natural gas and kickstart a boom. The nuclear age wanted to give the oil and gas age a hand up.
The current energy transition is powered by the realization that avoiding the catastrophic effects of climate change requires a reduction in greenhouse gas emissions. This infographic provides historical context for the ongoing shift away from fossil fuels using data from Our World in Data and scientist Vaclav Smil.

Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth’s climate, limiting terrestrial and aquatic food production. Here, we use climate, crop and fishery models to estimate the impacts arising from six scenarios of stratospheric soot injection, predicting the total food calories available in each nation post-war after stored food is consumed. In quantifying impacts away from target areas, we demonstrate that soot injections larger than 5 Tg would lead to mass food shortages, and livestock and aquatic food production would be unable to compensate for reduced crop output, in almost all countries. Adaptation measures such as food waste reduction would have limited impact on increasing available calories. We estimate more than 2 billion people could die from nuclear war between India and Pakistan, and more than 5 billion could die from a war between the United States and Russia—underlining the importance of global cooperation in preventing nuclear war.
France’s troubled nuclear fleet a bigger problem for Europe than Russia gas Giles Parkinson 5 August 2022 44 frederic-paulussen-LWnD8U2OReU-unsplash - optimised nuclear 669 Shares Share 669 Tweet Before Peter Dutton’s Coalition charge off into yet another inquiry into the merits of nuclear power, they might want to take a closer look at what’s happening in Europe, where the failure of France’s huge nuclear power plant fleet is causing bigger problems for EU power supplies than Russia’s withheld gas supply. France has been delivering just a fraction of its energy production potential in recent months, and overnight the situation got worse when French power producer EDF announced another three power plants would curtail output because of rising temperatures. Rivers have become too hot in the latest heatwave to be used to cool the reactors. The majority of France’s 56 nuclear reactors are currently throttled down or taken offline due to a combination of scheduled maintenance, erosion damage (worryingly, mostly a
The U.N. nuclear chief warned that Europe’s largest nuclear power plant in Ukraine “is completely out of control” and issued an urgent plea to Russia and Ukraine to quickly allow experts to visit the sprawling complex to stabilize the situation and avoid a nuclear accident. Rafael Grossi, director general of the International Atomic Energy Agency, said in an interview Tuesday with The Associated Press that the situation is getting more perilous every day at the Zaporizhzhia plant in the southeastern city of Enerhodar, which Russian troops seized in early March, soon after their Feb. 24. invasion of Ukraine. “Every principle of nuclear safety has been violated” at the plant, he said. “What is at stake is extremely serious and extremely grave and dangerous.”

The cost of decommissioning the UK’s seven ageing nuclear power stations has nearly doubled to £23.5bn and is likely to rise further, the public accounts committee has said. The soaring costs of safely decommissioning the advanced gas-cooled reactors (AGRs), including Dungeness B, Hunterston B and Hinkley B, are being loaded on to the taxpayer, their report said.
It doesn’t even work yet, but nuclear fusion has encountered a shortage of tritium, the key fuel source for the most prominent experimental reactors.

Russian soldiers who seized the site of the Chernobyl nuclear disaster drove their armoured vehicles without radiation protection through a highly toxic zone called the "Red Forest", kicking up clouds of radioactive dust, workers at the site said. The two sources said soldiers in the convoy did not use any anti-radiation gear. The second Chernobyl employee said that was "suicidal" for the soldiers because the radioactive dust they inhaled was likely to cause internal radiation in their bodies.
When the lights went out at Chornobyl Nuclear Power Plant on 9 March, the Russian soldiers holding Ukrainian workers at gunpoint became the least of Anatolii Nosovskyi’s worries. More urgent was the possibility of a radiation accident at the decommissioned plant. If the plant’s emergency generators ran out of fuel, the ventilators that keep explosive hydrogen gas from building up inside a spent nuclear fuel repository would quit working, says Nosovskyi, director of the Institute for Safety Problems of Nuclear Power Plants (ISPNPP) in Kyiv. So would sensors and automated systems to suppress radioactive dust inside a concrete “sarcophagus” that holds the unsettled remains of Chornobyl’s Unit Four reactor, which melted down in the infamous 1986 accident.

A Russian former foreign minister has joined a call for all sides in the Ukrainian war to return to diplomacy and so reduce “the dramatically elevated risk” of a nuclear conflict. The appeal co-authored by Prof Igor Ivanov, now the president of the Russian International Affairs Council, may be a sign that some in the Russian foreign policy establishment believe that pursuing a purely military solution in Ukraine is a strategic mistake.
On Sunday, Vladimir Putin ordered his nuclear deterrent forces to be placed on a “special regime of combat duty”. The Russian defence minister, Sergei Shoigu, has now clarified what this meant: the increased manpower devoted to Russia’s strategic nuclear triad: land-based strategic nuclear rocket forces, sea-based nuclear deterrents in the northern and Pacific fleets and its fleet of long-range strategic bomber aircraft that can carry nuclear weapons.

Scientists are hopeful that the National Ignition Facility’s recent success will advance understanding of thermonuclear reactions.
The U.S. nuclear power regulator last month suspended the shipment of radioactive materials and a hydrogen isotope used in reactors to China's largest state-owned nuclear company, CGN, reflecting Washington's concerns about the country's buildup of atomic weapons.
How close is nuclear fusion to break-even? If you trust the headlines we're getting close and the international project ITER is going to be the first to produce energy from fusion power. But not so fast. Scientists have, accidentally or deliberately, come to use a very misleading quantity to measure their progress. Unfortunately we're much farther away from generating fusion power than the headlines suggest. "Donc, si tout va bien, l'EROEI d'ITER sera de 0,4 ou 0,5 pour 1 - encore plus minable qu'un biocarburant basé sur les algues. " - Philippe Gauthier
