What if Germany had invested in nuclear power? A comparison between the German energy policy the last 20 years and an alternative policy of investing in nuclear power

Germany has one of the most ambitious energy transition policies dubbed ‘Die Energiewende’ to replace nuclear- and fossil power with renewables such as wind-, solar- and biopower. The climate gas emissions are reduced by 25% in the study period of 2002 through 2022. By triangulating available information sources, the total nominal expenditures are estimated at EUR 387 bn, and the associated subsidies are some EUR 310 bn giving a total nominal expenditures of EUR 696 bn. Alternatively, Germany could have kept the existing nuclear power in 2002 and possibly invest in new nuclear capacity. The analysis of these two alternatives shows that Germany could have reached its climate gas emission target by achieving a 73% cut in emissions on top of the achievements in 2022 and simultaneously cut the spending in half compared to Energiewende. Thus, Germany should have adopted an energy policy based on keeping and expanding nuclear power.

"AI is teaming up with nuclear power. And while that may seem like a worrisome bit straight out of a science fiction movie, chemical engineering professor Matt Memmott says it's not what it sounds like; no one is giving AI the nuclear codes. It's all about speeding up the process to get more nuclear power online."

Oh, I wasn't thinking "giving AI the nuclear codes". I was thinking "hallucinated nuclear reactor design". But, let's continue.

"The typical time frame and cost to license a new nuclear reactor design in the United States is roughly 20 years and $1 billion. To then build that reactor requires an additional five years and between $5 and $30 billion. By using AI in the time-consuming computational design process, Memmott estimates a decade or more could be cut off the overall timeline, saving millions and millions of dollars in the process -- which should prove critical given the nation's looming energy needs."

"Our demand for electricity is going to skyrocket in years to come..."

"Designing and building a nuclear reactor is so complex and time consuming because it requires multi-scale efforts, according to Memmott. Engineers deal with elements from neutrons on the quantum scale all the way up to coolant flow and heat transfer on the macro scale. He also said there are multiple layers of physics that are 'tightly coupled' in that process: the movement of neutrons is tightly coupled to the heat transfer which is tightly coupled to materials which is tightly coupled to the corrosion which is coupled to the coolant flow."

"When I was at Westinghouse it took the team of neutron guys six months just to run one of their complete-core multi-physics models."

"Memmott's research proves the concept of replacing a portion of the required thermal hydraulic and neutronics simulations with a trained machine learning model to predict temperature profiles based on geometric reactor parameters that are variable, and then optimizing those parameters. The result would create an optimal nuclear reactor design at a fraction of the computational expense required by traditional design methods."

Iran is in negotiations with China to purchase a tram/bus system for Tehran worth $12-$13 billion.

It is another push by Reisi's government to cut the pollution in the city and help with the out of control congestion caused by over 12 million cars in the city, most of them over 30 years old.

Iran seem to be increasing it's sale of oil significantly and planning to reach 4M barrels per day in 2025.

There are also reports that Iran is planning to build a second nuclear power plant in Sirik city in Hormozgan province, by the Persian Gulf. The plan is to produce 5GW or energy that is significantly larger than the Bushehr plant that in theory can produce 1GW but hasn't been able to produce more than 30% of max capacity.

Nuclear site hacked. Remember how at futurist meetings 10 or 20 years ago we'd talk about "science fiction" scenarios where critical infrastructure computers got hacked? Including nuclear power sites? Except this isn't a nuclear power site. Well, it's a nuclear site, but it doesn't generate power. Well, not any more. It was a power generation site, but there was a nuclear accident. This is known as the Windscale Pile no.1 fire, October 10, 1957. Windscale is near Seascale in the northern UK. After the radioactivity from that accident was contained, it became a reprocessing site for nuclear weapons. And got a name change from "Windscale" to "Sellafield". And it became a nuclear waste storage site. Today, it's considered so radioactive the purpose of the site is, allegedly, to decommission itself, and apparently that's so expensive it puts a major strain on the UK's budget.

The article says the hacking began in 2015, and that the journalists spent a year investigating it, and yet, paradoxically, says basically nothing about the hack. Who did it? "Groups linked to Russia and China". That's all we get to know. What did the hackers do? All we get to know is they got some documents. What sort of documents? We have this one sentence:

"Among the highly sensitive documents stored at Sellafield are disaster manuals, plans that guide people through emergency nuclear protocols and what to do during a foreign attack on the UK."

Sellafield nuclear site hacked by groups linked to Russia and China

The Guardian has discovered that the authorities do not know exactly when the IT systems were first compromised. But sources said breaches were first detected as far back as 2015, when experts realised sleeper malware – software that can lurk and be used to spy or attack systems – had been embedded in Sellafield’s computer networks.
It is still not known if the malware has been eradicated. It may mean some of Sellafield’s most sensitive activities, such as moving radioactive waste, monitoring for leaks of dangerous material and checking for fires, have been compromised.

Someone said to ChatGPT, "Design a nuclear reactor." Ok, he did a little more than that, pushing it to design something cutting-edge rather than a conventional design.

It designed an Advanced High-Temperature Molten Salt Reactor (AHTMSR). With a fusion neutron source for the thorium. (!) "Fusion-inside-fission". And with supercritical CO2 instead of water to drive the turbine.

Xcel Energy Shuts Down #Minnesota Nuclear Plant After Second Leak of Radioactive Tritium

Minnesota’s largest electric utility has temporarily shut down the Monticello nuclear power plant after reporting radioactive tritium was released into the surrounding groundwater near the Mississippi River. It’s the second such spill reported by Xcel Energy since November. Minnesota’s Pollution Control Agency reports the plant’s shutdown caused a massive die-off of fish due to a change in water temperature in the #Mississippi.

"According to the survey commissioned by Der Spiegel, carried out by the online polling firm Civey, only 22 percent of those surveyed are in favor of shutting down the three nuclear plants that are still in operation in Germany -- Isar 2, Neckarwestheim 2 and Emsland -- as planned at the end of the year."

"Seventy-eight percent of those surveyed are in favor of continuing to operate the plants until the summer of 2023, a variant that is being discussed in the political sphere as a 'stretch operation' -- in other words, continuing to keep them online for a few months, but without the acquisition of new fuel rods."

"Sixty-seven percent are in favor of continuing to operate the nuclear plants for the next five years, with only 27 percent opposed to it."

"On the question of whether Germany should build new nuclear power plants because of the energy crisis, 41 percent of respondents answered 'yes,' meaning they favor an approach that isn't even up for debate in Germany."

Why are nuclear power construction costs so high? "In the 1980s several nuclear power plants in Washington were canceled after the estimated construction costs increased from $4.1 billion to over $24 billion (resulting in a $2 billion bond default from the utility provider.) More recently, two reactors in Georgia (the only current nuclear reactors under construction in the US) are projected to cost twice their initial estimates, and two reactors in South Carolina were canceled after costs rose from $9.8 billion to $25 billion."

The article compares nuclear power to other sources of power, goes through nuclear plant basics, and outlines the cost.

But to zero in on the original question, why do the nuclear power construction costs go up so dramatically, the main answer, revealed bit by bit in great detail, is that the time it has taken to build the plants has increased, and this increased a variety of costs but the regulatory risk is where the increases primarily come from. 'Estimated time to build plants increased from just over 5 years in the late 60s to 12 years in 1980.' This increases various costs such as financing and labor. But the biggest problem is that over that span of time, the actual regulations that the plant must be built to change.

When regulations change, that forces a change to the design -- while the plant is under construction. This requires existing work to be removed or new work to be done, possibly in difficult conditions. "If a pipe needs to run through a beam, it's easy to design the beam to accommodate that ahead of time. But if it's a last-minute change, and the beam has already been fabricated, you might have to field cut a hole, or add reinforcing. Or maybe the beam can't accommodate the hole at all, and you need to redesign the entire piping system. And while this expensive redesign is happening, everyone else might need to stop their work."

A nuclear plant can employ 5,000 construction workers, but the real expense isn't even the actual construction workers, it's the expensive technical professionals and managerial staff that are necessary to meet the new regulatory requirements.

@Ferdi Zebua I’m declaring comments closed on this thread.

Feel free to test.

It's just sad when someone only goes with his confirmation bias and not only ignores any word which is said against it .. but even every fact which refutes it...

Best proof "comments closed" ... after deleting some comments from me contradicting the message of the post and linked video..

Just sad..

(Luckily, here in the #FediVerse ... i'm free to voice my concerns and critic anyways.. ;))

Lasers could cut lifespan of nuclear waste from “a million years to 30 minutes,” says Nobel laureate

Bild/Foto
Gérard Mourou has already won a Nobel for his work with fast laser pulses. If he gets pulses 10,000 times faster, he says he can modify waste on an atomic level. If no solution is found, we’re already stuck with some 22,000 cubic meters of long-lasting hazardous waste.

Mourou was the co-recipient of his Nobel with Donna Strickland for their development of Chirped Pulse Amplification (CPA) at the University of Rochester. “We think that in 10 or 15 years’ time we will have something we can demonstrate. This is what really allows me to dream, thinking of all the future applications of our invention.”

It would be good news, though, as then we’d really only have the operational risk of a nuclear power station. Protecting all the waste is already a very expensive and hazardous business.
