There is clearly a lot of fear about the #Zaporizhzya Nuclear Power Plant at present. The Russians are making threats, but how seriously should we take them?

What are the real likelihood AND severity of of these threats?

A thread 🧵/1
I work as a Clinical Psychologist and have a background in Physics. Last night, I discussed the possible Russian threats to the ZPP with nuclear experts Mark Nelson @energybants and Eugene Shwageraus @shwageraus on the #MriyaReport Twitter Space @MriyaReport /2
When scared about the chances of something terrible happening, we need to ask ourselves:

1) What specifically do I think might happen?
2) How likely is this to happen?
3) How bad would it be if it actually happened?

With nuclear power, we really need to ask & trust experts /3

Ex-Russian president warns of ‘accidents’ at @EU nuclear sites

Former Russian President #Medvedev has warned of possible #Accidents at European nuclear sites, also accusing the Ukrainian govt of risking a new #Chernobyl as its forces continue to launch attacks near a major #NPP Image
#Medvedev took to Telegram to sound alarms about the #Zaporozhye nuclear plant - which was captured by Russian troops in late Feb & continues to be operated by local personnel - claiming that Ukrainian bombs were gradually inching closer to the facility.

1/23: Energy makes the world go around. Many are questioning our dependence on non-domestic energy. What about #nuclear?

Starting my deep dive with Gwyneth Cravens book: Power to Save the World.

A 🧵 with excerpts from first 3 chapters: Image
2/23: Chapter 1: Survival

"Look at the big picture. If you got all of your electricity for your lifetime from nuclear power, your total share of waste would weigh two pounds and fit into one Coke can. Of that, only a trace is long-lived."
3/23: Chapter 1: Survival (cont'd)

If an American got all of his or her electricity from coal over a lifespan of seventy-seven years, that person's mountain of solid waste would weight 68.5 tons. Picture a soda can next to that. Huge Coca Cola Can, Atacama...

Thread: 29 July 2022: Day 156 of #Russia's invasion of #Ukraine
Latest @DefenceHQ update is on the "Wagner" unit, says its "new level of integration [with the #Russian Army in eastern #Ukraine] further undermines the Russian authorities' long-standing policy of denying links between PMCs and the Russian state". Which is British understatement Image
The #Biden administration continues denying #Ukraine weapons, in this case ATACMS surface-to-surface missiles, because of its deranged fear of #Russia "escalating", as if that is an actual Thing at this point.

Alla fine di marzo, l'esercito russo ha lasciato il territorio della centrale nucleare di Chernobyl, ma anche a causa del fatto che avevano scavato trincee, i livelli di radiazioni erano aumentati nell'area. Ora, secondo il rappresentante dell'AIEA, sono tornati alla normalità.

Really important question below: why would you even design a T-72 so that the crew literally has to sit on top of hundreds of kilos of highly explosive ammunition and propellant? /1
@clmazin answered this by analogy in his brilliant script for #Chernobyl. In the (fictional) courtroom scene in the final episode, Soviet nuclear scientist Valeriy Legasov explains why Chernobyl was effectively rigged to explode: /2
"It's cheaper". That's the answer to the T-72's design flaws. It's much smaller and lighter than the US M1A1 Abrams or similar British and German tanks. But it costs a fraction of their price, at the cost of crew safety. /3

Retour sur cette partie de la série #Chernobyl, où Legasov explique que la soudaine hausse de réactivité a été causée par le fait que l'extrémité des barres de contrôle était en graphite et que c'est elle qui est entrée en 1er dans le cœur.
La vraie explication est + complexe 🔽
Dans la série, Legasov présente cette conception des barres (en bore avec extrémités en graphite) comme une négligence qui aurait été dictée par le fait que "c'est moins cher".
Le spectateur en déduit alors que normalement elles auraient du être 100% en bore...
En fait, non, cette extrémité en graphite était normale et permettait le bon fonctionnement du réacteur.
Ce n'était même pas une "extrémité", mais une section qui avait une hauteur proche de la partie absorbante en bore (4,5m contre 6,2m).

Sempre riguardo #Chernobyl, ci sono ulteriori novità. Secondo il canale Telegram "Можем объяснить" mercenari del gruppo Wagner hanno sofferto per l'esposizione alle radiazioni nella zona di esclusione di Chernobyl.…
Due mercenari, in particolare, hanno raccontato al corrispondente di "Можем объяснить" di alcuni loro compagni d'armi che si sarebbero ammalati.
Secondo il loro racconto, i mercenari di Wagner sono stati utilizzati per tenere le posizioni in direzione di Kiyv. Poco dopo la ritirata delle truppe russe, i mercenari hanno avuto bisogno di assistenza medica e sono stati evacuati di fretta e furia in Bielorussia.

Non è finita qua su #Chernobyl a quanto pare. I militari russi nella zona di Chernobyl hanno saccheggiato due laboratori di ricerca e rimosso fonti di radiazioni ionizzanti e campioni di materiali combustibili.
Lo ha riportato il media indipendente russo Mediazona, citando l'Agenzia statale ucraina per la gestione della zona di esclusione.…
I militari russi "hanno rubato e danneggiato 133 fonti di radiazioni ionizzanti con un'attività totale di circa sette milioni di becquerel", afferma il rapporto.

Petro Kotin, il direttore di Energoatom, insieme ai dipendenti della società ha visitato uno dei lotti nella zona di esclusione di #Chernobyl dove le truppe russe stavano scavando trincee e cercando di costruire strutture di fortificazione nella Foresta Rossa.
Nel sito sono stati registrati livelli di radiazioni anormalmente alti.

1️⃣ Il livello di radiazione background gamma ambientale nei luoghi misurati era di 3,2-4 µSv/anno (microsievert/anno), che è 10-15 volte più alto del normale.
2️⃣ Uno degli indicatori della contaminazione interna ricevuta dagli occupanti dal suolo (contaminazione Beta) è 90 Sr, 160 volte la norma.

Abbiamo geolocalizzato la posizione del video delle trincee 🇷🇺 a Chernobyl, in verde nella mappa delle radiazioni, ed in rosso in google maps.
Considerando il tempo per cui è stata occupata la centrale, i soldati 🇷🇺 nelle trincee sono stati esposti a quantitativi di 1/ ImageImageImage

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.
Breathing and ingesting dust, smoke, or food from the area stands to raise their statistical lifetime chance of cancer.

Probably no immediate effects, however, because ARS needs a huge radiation shower in one hit, which is unlikely 36y after the accident.

Welcome to the weekend and to Day 38 of the Kremlin war on #Ukraine.

More morale problems for Russia with irradiated troops, heavy losses amid the withdrawal from #Kyiv and still question marks over the bombing of the fuel depot on Russian soil.

All the news, all day, in this🧵
I am still gathering news and data on the Russian attacks on #Ukraine during the night.

#Kharkiv again looks to be worst hit, with endless explosions heard. Some fires burn - this one video submitted. Remember exact locations cannot be revealed, hence the blurring

British intelligence highlights the two recent incidents in #Belgorod, the Russian city close to the border with Ukraine.

Although Ukraine denied the attacks, UK wouldn't highlight this unless it believed they did it, so I bow to the military intel.

Day 37 of #Russia's war in #Ukraine and this is Friday's daily thread of news & developments.

First let's have a look at the UK govt's view of the situation today. Ukraine continues to make progress towards breaking the siege of #Chernihiv.
They also still edge towards #Kherson
Sometimes dark humour is the only way to cope when your neighbour has launches a totally unprovoked war on you...

Did they or didn't they?
#Russian border town of #Belgorod got hit again with a fire at an oil depot.

Russia blames Ukraine, which has so far refused to admit the strike.

BREAKING - The #Ukraine state enterprise EnergoAtom reports that the #Russian Army units that captured the defunct #Chernobyl nuclear power plant are leaving the plant in two convoys of about 100 vehicles to #Belarus. [Thread⬇️]
[2] On the morning of March 31, the #Russian Army commanders expressed to the #Ukrainian personnel at the #Chernobyl nuclear power plant their intentions to leave the station for Belarus. Sources: #Ukraine state enterprise EnergoAtom + State Committee of Special Communications.
[3] Yesterday's information had been confirmed by EnergoAtom that the Russian soldiers indeed dug the trenches in the highly radioactive Red Forest. After the first symptoms of Acute Radiation Syndrome (ARS) Russian soldiers began panicking, revolting, and demanding retreat.

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.
Now, looking into the story more, I find there's no real substance to it. Here's why:

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:
1. The most intense radiation comes from nuclear material with a short half-life – decaying fast and giving off all its radiation in a hurry. We're talking seconds, minutes and hours. More than 35 years after the accident, that stuff is gone.
