spent fuel contains ~97% of the radioactivity of the nuclear power sector's waste.
in the US, spent fuel sits at each reactor in cooling ponds or in large concrete & steel casks, awaiting resolution of the political impasse holding up long term storage/disposal of that waste.
spent fuel represents only about 2% of the nuclear power sector's waste (by weight) — that's not including the waste from milling uranium ore.
there's a *lot* more waste than zealots know about / will admit.
i'm *not* saying the waste is *not* well managed these days, but if you're going to say that there's no landfill waste from #nuclear power… you're going to get a thread! 😛
(there are good & bad nuclear advocates out there — bad ones mix ignorance with half-truths & zealotry.)

actual photo of @sussanley just now successfully urging the world heritage committee *not* to list the #GreatBarrierReef as “in danger”.
😞
(our gov’t made more calls to stop recognition of the reef’s perilous state than it did to secure covid vaccines.) #auspol
the committee did recognise:
• the long-term outlook has deteriorated from ‘poor’ to ‘very poor’
• progress to date has been insufficient
• climate change remains the most serious threat
…and…
…australia is required submit a report next february, to be considered at the 45th meeting of the committee in russia this time next year.
hopefully our _next_ minister for the environment will urge the world to save the reef.
for power sector:
• total renewables set to double over next decade, as they did over the last decade
• LNG to halve, back to levels not seen since ~1993
• coal down 45%, back to 1998 levels
• nuclear to recover to ~70% of pre-fukushima levels
• consumption set to fall by 9%
the new plan is expected to reduce electricity emissions by 46%.
(nb. there are plans for reducing emissions from other sectors of the economy… this is just the electricity sector.)
🧵22 june marks @hepburnwind's 10th anniversary of generating clean energy!
since the very first kWh sent into the grid ten years ago, gale & gusto, the two turbines of australia's first community-owned wind farm have generated more than 100,000,000 kWh!
here's how it happened:
in 2004 a developer proposed the clarkes hill wind farm, about 30km from #daylesford.
a number of daylesford locals went along to the dean town hall for a "community consultation", excited to hear all about it.
but when they arrived, the atmosphere was hostile, almost violent!
the developer was run out of town & the anti-wind mob — themselves largely from out of town — celebrated a "victory".
the daylesford crew left the meeting devastated that the community's first response was knee-jerk opposition.
on the way home they promised to change the story.
many eyes on reported leak at #taishan nuclear power station, close to hong kong.
doesn't help that french part-owner has warned of an "imminent radiological threat", but the fact that US is monitoring closely & hasn't raised alarm should be of comfort.
🧵nuclear zealots like @Dr_Keefer often claim that wind turbines and solar panels last only 20 years.
…and that nuclear plants are somehow "immortal".
one problem: that's 🐂💩!
it’s not unusual for solar panels to come with a 25 year warranty these days.
the manufacturer of my solar panels claims they have a *40* year useful life, and guarantee that at 25 years they’ll still be 92% as productive as they were when brand new.
#ontario solar manufacturer @SilfabSolar claims the world's longest performance warranty — at least 82.6% of their original power at the end of their 30th year.
