put some generators on roof. Generator placement in Jp was based on BWRs placement in US - underground, which is sane considering tornados and stuff. But it wasnt adapted there
Moldoteck··on Belgium stops decommissioning nuclear power plants
the cost problem is lost experience to build stuff. It's not like berlins airport is so expensive because of new whistles. Many western nations forgot to build. Japanese ABWR has a lower core damage frequency vs french EPR yet EPR took 20y and ABWR - 4

It's impossible for germany to have such a combo in any economical way.
Moldoteck··on Belgium stops decommissioning nuclear power plants
it depends if you like gas firming or not. France doesnt. Germany loves it
Moldoteck··on Belgium stops decommissioning nuclear power plants
yep. On the other hand, interestingly, most nuclear deaths are from Fukushima evacuation which wasnt necessary, due to too small dose
Moldoteck··on Belgium stops decommissioning nuclear power plants
Korea is close now. But closest was japanese abwr- cost similar to current Chinese units

Not that exorbitant. Npp operators are paying for dismantling themselves (except soviet/experimental units). Waste storage (Interim/final) was paid too through KENFO which is massive and agreed by all parties, incl greens. I guess this transport will be financed from that fund too.

Germany could recycle all that waste at la Hague, build a repository Like Onkalo and still have leftover money. If for some reason KENFO isn't enough, chiefs of BMUV and BASE should be investigated For treason and wasting public money. Germany could even deal with this cheaper by allowing storing the waste at facilities like herfa neurode. This would also solve storing waste from medical and research sectors

Moldoteck··on Belgium stops decommissioning nuclear power plants
Their insurance, cleanup is included in state mandated price. Their capex loans aren't so problematic since it costs about 2.5bn to build and is done in under 5y now

China doesn't have free market in the way we have it anyway. It wasn't valid even for solar

Moldoteck··on 1.4 GW: battery storage at former Grohnde nuclear power plant
You can store it on site for as long as the site is operational which means(if you allow extensions/relicensing) about 80-100y. Afterwards you need a repository similar to Herfa Neurode or Onkalo.

The cheapest way in Germany would be either to allow storing in Herfa Neurode or to send waste to la Hague for recycling, sell the recycled part and isolate only the leftovers.

Renewables don't isolate you from this problem. Germany still needs a repository for medical and research waste. Germany also needs repositories for toxic chemicals (arsenic, cadmium, lead- byproducts of various industries including renewables)

Even more, Germany can't get by with solar+wind+bess alone. Fraunhofer ISE recommends massive gas expansion to 80+GW to firm renewables. I'd rather see any fossils infrastructure erased from existence. France doesn't need a parallel fossils firming grid. Nor Sweden.

Moldoteck··on 1.4 GW: battery storage at former Grohnde nuclear power plant
Depends. People don't understand the idea of learning curves related to nuclear. If you don't fix your problems in second build you'll still make same mistakes. On the other hand if you do proper planning you can achieve instantly N of a kind costs, like first japanese ABWR.

Ren infra has own risks too. For example concentration in best weather areas. Most ren infra in Ukraine was in the south and was either captured or destroyed by Russia. There are similar risks in for north sea/offshore projects

Moldoteck··on 1.4 GW: battery storage at former Grohnde nuclear power plant
For me "it could absolutly be turned back on" is tied to "if refurb is done for affected components"

I'm sure Framatome will be more than happy to help with manufacturing of necessary parts. Great carenage is already undergoing in France which helped in this regard but Framatome is involved in manufacturing for other suppliers too

Moldoteck··on 1.4 GW: battery storage at former Grohnde nuclear power plant
"Dozens of above ground areas need to be secured for thousand of years." - why? Do you think for terrorists it'll be easy to dig a 500m deep hole to reach Onkalo's sealed facility? Instead of creating some chemical agents that can do vastly more damage for much cheaper? For real some of you live in a fantasy world. Nor you seem to be concerned about facilities like Herfa Neurode in this regard.
Moldoteck··on 1.4 GW: battery storage at former Grohnde nuclear power plant
at german electricity prices bess business is good
Moldoteck··on 1.4 GW: battery storage at former Grohnde nuclear power plant
how much would costs increase? German nuclear was cheapest firm power in merit order
Moldoteck··on 1.4 GW: battery storage at former Grohnde nuclear power plant
a npp benefits a lot from the batteries. Nuclear can be flexible and flexibility can be boosted with BESS buffers. Basically BESS would act similar to hydro in this case
Moldoteck··on 1.4 GW: battery storage at former Grohnde nuclear power plant
No you dont rebuild it from ground. You do refurb which is relatively cheap. Canadian Darlington refurb costed about 3bn/unit with major components replaced fully. That's dirt cheap for ±1gw of firm power. Other refurbs costed less.

Sourcing uranium is not an issue. In fact per kwh nuclear requires least amount of materials and hence, imports https://ourworldindata.org/low-carbon-technologies-need-far-... Heck Germany can even extract it from seawater in worst case. Nowadays it's not that much more expensive vs land mining. But soon Sweden will be a player too, along Canada/Australia

Npp in germany were insured by law with insuring pools. On top, operators had full asset liability, again, per law. Closest catastrophe event would be TMI. Cleanup there is merely 1bn...

Russian war shows nuclear is great regardless. Ukraine's grid still has power even though most ren infra got destroyed/captured because most was deployed in south with better weather. Germany is in similar situation with northern offshore parks

You remember chernobyl which is expected to kill at most 4k ppl or much less per UNCSEAR but you are probably fine with german car industry which kills same amount of persons in merely 2y from impacts, right? You are fine with coal still operating which killed even more? You are fine with gas being used for firming? (habeck, reiche, fraunhofer) Phaseout was a terrible decision https://link.springer.com/article/10.1007/s10640-025-01002-z

France has decentralized grid with centralized multiunit locations. This reduces heavily grid investment needs. There's a reason Germany spends 10x vs France on transmission and curtailment

Moldoteck··on 1.4 GW: battery storage at former Grohnde nuclear power plant
Terrorism and drone strikes are irrelevant. Casks can withstand train/rocket impacts.

It can be turned on by pursuing refurbs like Darlington in Canada which would be closest conceptually since a lot of stuff got replaced there. Refurbs would be cheap vs building anything new providing same TWh/year. Germany needs much more than just batteries. It needs gas firming on top (coming from Habeck, Fraunhofer and now Reiche)

Moldoteck··on 1.4 GW: battery storage at former Grohnde nuclear power plant
yes, you can do refurbs which arent that expensive.

Nuclear waste storage is politically killed centrally. Look even at formulation in the law which demands "best" location. Germany could solve this problem in a second if it allowed storing waste in facilities where toxic chemicals are stored like Herfa Neurode.

Asse was an experimental facility that didnt have a plan of what to do if experiment goes sideways. It has nothing to do with final repositories like Onkalo. Still, it killed noone. Nor will it. Most of the waste there is from medical and research sectors and is LLW.

Moldoteck··on Belgium stops decommissioning nuclear power plants
I know, full system lcoe must be considered with all bells and whistles. I'm comparing lcoe of worst nuclear project in us vs lcoe of hydrogen peakers
Moldoteck··on Belgium stops decommissioning nuclear power plants
France does not have a fully parallel nuclear power grid ready to step in when some other half isnt working. Germany has a fully parallel fossils firming grid on top of their ren deployments.

EDF isnt crying. It's just treated poorly even by looking at ARENH tax which was replaced with another one this year, while ren business gets CFD's and curtailment payments.

French nuclear fleet is extremely flexible, RTE data is public. In fact, due to ARENH law EDF was forced to subsidize competition because otherwise that competition would not exist.

Moldoteck··on Belgium stops decommissioning nuclear power plants
it's not a wrong word. Competitive - it's in the sesnse of what price can it sell to get profits, even if the price is set by govt. Even our existing fleet of npp is competitive on the market ->

But chinese nuclear is built faster and cheaper vs our units even during messmer in france. So their price guarantee is lower too. Probably similar to what distributed solar got there of 0.4y/kwh in the past. Albeit subsidies for solar were cut last year to stimulate a healthier growth

Moldoteck··on Belgium stops decommissioning nuclear power plants
it's not about ussr, what a nonsense. It's about having good supply chain. Like France had during messmer or Korea now (albeit far from china). China is building the same ap1000 copycat much faster and cheaper
Moldoteck··on Belgium stops decommissioning nuclear power plants
nobody is offsetting anything, it's accounted, please dont spread this tired russian propaganda nonsense https://www.kkg.ch/de/uns/geschaefts-nachhaltigkeitsberichte... Or search what's onkalo. Or what we do with arsenic/cadmium/lead waste
Moldoteck··on Belgium stops decommissioning nuclear power plants
the choice here was nuclear or new gas from engie
Moldoteck··on Belgium stops decommissioning nuclear power plants
considering nuclear needs least mining, i doubt effects are too big per kwh vs alternatives.
Moldoteck··on Belgium stops decommissioning nuclear power plants
asse was never intended to be final repository. It was experimental repository without a plan to extract the waste if their experiment goes sideways. Onkalo does account for such factors, hence the name- final repository

Most of the waste in asse is from medical and research sectors

Moldoteck··on Belgium stops decommissioning nuclear power plants
most of Ukraine's ren infra is destroyed or conquered by russia. Zaporozhie is in cold shutdown. Thousands died from dam collapse caused by russia.

Waste is irrelevant for bombs due to parasitic isotopes. You clearly have zero idea about the topic.

France pays no subsidies(yet, epr2 is another topic). In fact EDF was forced to pay a tax till this year called arenh to subsidize competition. This year that tax was replaced by another tax. Many read the law wrongly about 70eur. It's not that EDF will get guaranteed CFD. It's that EDF will be forced to pay EXTRA tax IF it sells above that limit. French prices dropped both in 2025 and now in 2026. French households have lower prices vs german ones per eurostat.

Basically all your statements are nonsense antinuclear rambling

Moldoteck··on Belgium stops decommissioning nuclear power plants
they havent found one bc they dont want to. Otherwise they would approve storing in say, herfa neurode
Moldoteck··on Belgium stops decommissioning nuclear power plants
germany has highest prices in eu without any nuclear. It spent on eeg double the cost of entire french fleet. and that fleet wasnt even very cheap looking at what china does now. Germany also needs gas firming per fraunhofer ise report since bess is not sufficient
Moldoteck··on Belgium stops decommissioning nuclear power plants
phaseout was adopted by redgreens in 2000 and continued by cdu in 2011. THat's a fact German solar was just not competitive - labor, electricity and coal were more expensive in germany. Solar industry was showing problems even before cfd's reduction (which applied to chinese ones too but they endured since costs were lower)
