Together Against Sizewell C

Radioactive water from Dounreay nuclear site leaked in major breach RADIOACTIVE material was accidentally released at Scotland’s Dounreay nuclear site in a major environmental breach, The National can reveal ...

"It is a telling sign that we must move away from unstable, harmful, wasteful energy sources like nuclear immediately,...Harmful waste being released into the environment, accidentally or otherwise, has a knock-on effect on our own lives and the world around us."

Zaporizhzhia "has now been without off-site power for almost two weeks, forcing it to rely on emergency diesel generators for the electricity it needs to cool its shutdown reactors and spent fuel. This is an extraordinarily challenging situation," www.iaea.org/newscenter/p...

No surprise - the North Sea continues to erode the coast in front of the Sizewell C site & now appears to be less than 20 metres from the site boundary where the temporary sea defences are being constructed. Sizewell C - a #climatechange casualty, not a solution

Excellent words from Mandy Beaumont at the Middleton Oaks protest- "None of us can bear to see the environmental devastation we are witnessing all around us here - all in the name of progress by Sizewell C’s government-backed machinery that appears to be pre-programmed with a “scorched earth policy”

Zelenskyy sounds alarm over unprecedented power outage at Zaporizhzhia nuclear plant Ukrainian president says Russian shelling is preventing work to restore links to grid and that one of the plant’s diesel generators has failed

"Zelenskyy said: “This is a threat to everyone. No terrorist in the world has ever dared to do with a nuclear power plant what Russia is doing now. And it is right that the world not remain silent.”"

I think this is why they changed the name from Area of Outstanding Natural Beauty to National Landscape. It doesn't sound as bad to build on a national landscape as that describes everywhere. AONB is very specific.

A wonderful turnout to celebrate saving these 8 precious oaks from the Sizewell C chainsaws. Huge thanks to Mandy Beaumont who ran such a successful campaign on behalf of the surrounding villages to stop the needless destruction of such valuable wildlife habitat by Sizewell C

... particularly reckless when dealing with nuclear power. And it is even more so if Britain is to take the Trump administration on its word that a particular reactor has been deemed safe by the US & therefore requires no safety scrutiny by UK regulatory authorities." 2/2

The ‘Golden Age of nuclear’ deal is all a veneer AT THIS point there is no need for any of us who are inclined toward commentary to further point out the utter dereliction of the Keir Starmer government. It is doing a perfectly fine job on its own.O...

...Also vast areas of East Suffolk's countryside are being devastated for building the roads, roundabouts, rail, car parks etc to enable Sizewell C to be constructed and operated, effectively industrialising this precious rural landscape.

Villagers to stage demonstration over felling of Suffolk oaks Villagers fighting Sizewell C plans to remove historic oaks will be staging a demonstration in Middleton on Thursday.

"The demonstration calling for work to pause on the relief road will take place tomorrow (Oct 2nd)...the villagers are not just concerned about the loss of mature trees, but also the use of the B1125 as a "rat run" for Sizewell traffic."

Sizewell C will increase bills with effect from this winter to help pay for the build & not a kw of electricity will be generated for 10-15yrs, if ever.

Ukraine war live: Nuclear plant in ‘emergency situation’ says Zelensky after shelling UN atomic watchdog has repeatedly warned of the possibility of a radiation catastrophe such as Chernobyl

"cracked graphite brick failure causes the nuclear fuel to overheat, the core is misaligned and fuel modules get stuck” threatening the City of Lancaster and the Lake District - what’s not to like?! The following is ongoing correspondence with Lizzi Collinge MP for Morecambe and Lunesdale regarding Heysham’s dodgy old nuclear reactors….

"Given the UK is far from short of electricity generating capacity & that Heysham produces a tiny fraction of the UK’s electricity it is surely not worth the high consequence risk of a catastrophe resulting from continuing to run these reactors."

13/ Prioritising nuclear raises energy justice concerns in addition to the higher cost of 2.3% of GDP. RE promotes decentralisation, equity, and participation. Nuclear reinforces centralised regimes and burdens future generations with long-term waste management.

9/ Key results show nuclear scenarios lead to 99–115% higher levelised cost of electricity (LCOE) compared to the BPS-ref in 2050 (70.1–75.8 €/MWh vs. 35.3 €/MWh). The cost-optimal RE system is dominated by wind power (54%) and solar PV (30%).

5/ SMRs are modelled for both electricity & combined heat and power. SMR technology is not yet commercially available, posing greater financial risks than renewables with continuously declining costs. SMR investment cost consider its growth, learning rate, and economies of scale.

1/ New @lut.fi study in collaboration with European partners finds prioritising nuclear power expansion over renewable energy (RE) leads to 71–84% higher annual system costs in Finland by 2050 compared to a cost-optimised RE system. doi.org/10.1016/j.en...

I don't think the best way to solve cybersecurity issues is by building NPPs. Buying inverters with OSS and good cryptography seems cheaper and more effective to me. (Or diversify where you get your inverters.)

Are you suggesting it's a good idea to hide costs by putting government on the hook.

Bottom line: nuclear has been getting away with underestimating costs for decades as far as I can see.

But the most important problem (and you often say yourself): baseload is not really needed anymore. So what is the role of nuclear? Unless you go fully nuclear.

This value of diversification... I don't see it tbh. Is that in case there's no longer sun or wind?
Regarding the cost of capital: I think it should actually include predictable cost overruns and hidden subsidies like government taking care of disasters and waste during 10s of thousands of years.

I'm glad that @christianonre.bsky.social increasingly includes nuclear in his analysis, if only to show that adding nuclear is really more expensive than a system running completely (100%) on renewables.
