The headline: Wind and solar were the EU’s top electricity source in 2022 for first time ever

The reality: Wind and solar were the the EU's 4th and 6th biggest sources of electricity, respectively, in 2022 The data:

Nuclear: 21.93%
Gas: 19.17%
Coal: 14.55%
Wind: 13.42%
Hydro: 12.60%
Solar: 7.29%
Bioenergy: 5.88%
Other fossil: 3.55%
Other renewable: 0.24%

The situation at #Ukraine's #Zaporizhzhia nuclear power plant has gotten more volatile in recent days, with both sides in the conflict pushing the envelope of what they do at the site and even some shelling. I'm catching up, but here's what I know about it: Since its occupation on 3 March the site has been in a very uneasy mode of operation with Russian forces controlling the site while Ukrainian technicians conduct operation under constant close scrutiny. It wasn't pretty but it was stable.

In March, Ukraine's electricity grid was synchonised with the main European grid, ENSTSO-E, so that other countries could help Ukraine keep the lights on during the war.

Electricity will flow from today, but it will go THE OTHER WAY with Ukraine alleviating shortages in the EU. Ukrainian energy minister Herman Halushchenko said exports would start at 100 MW as ENTSO-E assesses the grid stability impact of that. But Ukraine could supply 1690 MW and, with technical upgrades, as much as 5000 MW. Herman Halushchenko sitting at a desk with files

Oh dear, oh dear, oh dear...

Some evidence that Russians were indeed dumb enough to dig trenches near #Chernobyl. See here some previous tweets on why I (and others) think Acute Radiation Syndrome is unlikely, but that doing this is definitely 'not good' and could have health effects in the long term.

Some collected thoughts on what's going on with Russian troops in the #Chernobyl Exclusion Zone and whether they have gotten themselves sick 🧵

(Spoiler: No) Earlier today the idea that Russian troops around #Chernobyl had developed Acute Radiation Sickness was going viral. I did this thread to explain why that struck me as highly unlikely.

There have been a lot of questions about nuclear issues in Ukraine since the war began. Here's a thread of my explanations if anyone wants to catch up.

A run-down of nuclear power plant construction and essential safety systems in the context of troops approaching Zaporizhzhia nuclear power plant

This story is going round, but I think it is unlikely that Russian soldiers developed Acute Radiation Syndrome while messing around in the #Chernobyl Exclusion Zone. I'll explain my thinking in a short 🧵 Acute Radiation Syndrome is a very rare thing caused by a super-intense dose of radiation to the whole body.

It happened to some plant operators and firefighters during the #Chernobyl accident in 1986, but I'm doubtful it happened to Russian troops in 2022 for three reasons:

China's Hongyanhe nuclear power plant is to heat 20,000 people's homes in a project that will begin by cut coal use by over 12,000 tonnes.

Here is a little 🧵 on this growing trend cutting China's coal pollution, saving lives and $$$ billions.
world-nuclear-news.org/Articles/Distr… Hongyanhe is a big nuclear power plant in northwestern China. It has five reactors that have been built since 2009, while the sixth will start up in the next few months.

UK opposition party Labour is just as solidly behind nuclear to cut fossil fuels as the Conservatives in power. No timidity from either party in saying the word any more. ImageImage In fairness both have long been pro-nuclear. Conservatives naturally so, while Labour actually launched the original UK nuclear R&D push and its first power plants back in the day. Labour did go a bit soft on it under Jeremy Corbyn, however, and shied away from saying the word.

There are reports that #Kharkiv Institute of Physics in #Ukraine has been hit by rockets. It contains a small #nuclear research facility. I'll tell you what I understand about it and what's going on in this thread: #Kharkiv has a 'sub-critical assembly'. That means that by design it does not have an ongoing chain reaction. Reactions only occur when triggered by an external source. This whole setup has been switched off since the invasion began.

There was an update this morning on #Zaporizhzhia and other nuclear power plants in #Ukraine from the plant owner, Energoatom.

Importantly, the situation is calm and nuclear operation is normal.

Details below: Energoatom said that as of 9.30am its nuclear plants were all stably generating power for Ukraine. That includes #Zaporizhzhia. It notes that the country's power needs are being met.

I have woken up to reports of fighting at the #Zaporizhzhia nuclear power plant. In this thread I will summarise what I understand about the situation. First, a quick rundown of the most important safety aspects of a nuclear power plant's design:

'Engineering supremacy' is a major reason the nuclear industry can't have nice things. A rant by me. In the last few days I encountered a troll who tried to undermine me by saying I have no value because I work in communication and not engineering.

The entire city of Haiyang in China is now heated by its nearby #nuclearenergy plant, making it the country's first city to transition away from fossil-fired district heating.

The Haiyang plant has two Westinghouse AP1000s that started up in 2018 and 2019. By providing heat as well as power to Haiyang's 2 million people the nuclear plant has replaced 1️⃣2️⃣ coal boilers, saving:
🔥 10 million tons of coal each heating season
🌏 18 million tons of CO2
😷 691 tons of soot
😷 1123 tons of nitrogen oxide
😷 1188 tons of sulphur dioxide

I'm so busy following #nuclearenergy developments at #COP26 I've been too busy to tweet. (I know right?) I'm going to catch up through today with a thread of quotes I've picked up and stories I've filed. 👇 'Evolution' in EU nuclear debate
European industry body Foratom is hopeful that a new conversation around nuclear energy will bring the policy framework needed for it to make a major contribution to 2030 energy targets, a Moody's webinar heard.

For the first time ever my wife @_TheFG_ has complained that I'm not tweeting, so let's put tat right with a little 'Postcard from #COP26'. Image The reason I hadn't tweeted is that I was too busy taking it in and talking to people. COP is huge, because this is a huge problem. It needs to be solved for everybody, and that can't happen unless everybody is included.

We had some discussion recently about how to talk about safety of #nuclearenergy. In my opinion you shouldn't talk about it unless somebody asks, but of course not everyone agrees because some people are wrong. 😉

Here's a thread with some slides I use to make my argument.👇 Great research from @AmyCuddy identified two characteristics that are super important when we form opinions of others: Warmth and Competence. Testing here with Star Wars characters it's clearly a useful way to think about our own appearance to others.
