And of course today Russia is pressing ahead on the Advanced Nuc expansion.
As are China and India
But what do they know?
Interesting info on radiation levels

..its different technology.
Advanced Nuclear does not involve the high pressure and the possibility of the run away reactions.
It was designed to AVOID most if not all of the pitfalls of the Gen1 and 2 reactors-Light Water Reactors.
You are making a point based on 1970 design.
Are we doing that with anything else?
Redman wrote:It seems so-BUT there are different types of the new designs so I cant say with 100% certainty that there is a single answer to your Q.
But the first MSR reactor in the 60s was walk away safe-and they used to leave it running over the weekends and go home.
Most of what Ive read indicates that the various designs today have engineered the process to be that safe--The temps get too high the nuclear reaction slows....a loss of power-the ICE plug melts and the radioactive stuff is drained into a 'sump' and cools....Plane or bomb-the Molten salt cools/solidifies irrevocably bonding to the radio active stuff-containg itself almost.
All the above stops the chain of reactions and a runaway to a meltdown or a Hydrogen explosion seems impossible(again on my limited knowledge)..
The ability to refuel online means that there less Radioactive material in the reactor at all times.
So I think the tech is close to intervention free-at least in the critical stages of a problem

What's clear? There are no dates . Coal, oil, and gas have been around for much much longer, so statistically they are going to be higher. You cannot lump all together, and selectively present data.

Secretive energy startup backed by Bill Gates achieves solar breakthrough

New York (CNN Business)
A secretive startup backed by Bill Gates has achieved a solar breakthrough aimed at saving the planet.
Heliogen, a clean energy company that emerged from stealth mode on Tuesday, said it has discovered a way to use artificial intelligence and a field of mirrors to reflect so much sunlight that it generates extreme heat above 1,000 degrees Celsius.
Essentially, Heliogen created a solar oven — one capable of reaching temperatures that are roughly a quarter of what you'd find on the surface of the sun.
The breakthrough means that, for the first time, concentrated solar energy can be used to create the extreme heat required to make cement, steel, glass and other industrial processes. In other words, carbon-free sunlight can replace fossil fuels in a heavy carbon-emitting corner of the economy that has been untouched by the clean energy revolution.
While other concentrated solar companies attacked this temperature problem by adding steel to make the technology stiffer and sturdier, Heliogen and its team of scientists and engineers turned to artificial intelligence.
Heliogen uses computer vision software, automatic edge detection and other sophisticated technology to train a field of mirrors to reflect solar beams to one single spot.
"If you take a thousand mirrors and have them align exactly to a single point, you can achieve extremely, extremely high temperatures," Gross said, who added that Heliogen made its breakthrough on the first day it turned its plant on.
Heliogen said it is generating so much heat that its technology could eventually be used to create clean hydrogen at scale. That carbon-free hydrogen could then be turned into a fuel for trucks and airplanes.
"If you can make hydrogen that's green, that's a gamechanger," said Gross. "Long term, we want to be the green hydrogen company."
'No-brainer'
For now, Heliogen is squarely focused on solar. One problem with solar is that the sun doesn't always shine, yet industrial companies like cement makers have a constant need for heat. Heliogen said it would solve that issue by relying on storage systems that can hold the solar energy for rainy days.
Now that it has made this breakthrough, Heliogen will focus on demonstrating how the technology can be used in a large-scale application, such as making cement.
"We're in a race. We just want to scale as fast as possible," said Gross.
After the large-scale application, Soon-Shiong said Heliogen would likely be ready to go public.

Getting to Zero Emissions by 2050
To mitigate the most serious threats posed by climate change, we must get to net-zero carbon emissions as fast, and fairly as possible. This means using every clean energy technology we have and investing in innovation to create or improve the clean energy technologies and fuels we still need to eliminate climate pollution in every sector of the economy.
One of the most promising new technologies to help get to zero carbon is advanced nuclear power, which could be paired with renewables to generate electricity, provide heat and power for industry, or produce hydrogen. Since 2015, we have been tracking the evolution of advanced nuclear innovation projects in the United States and Canada. As new industries mature, it is natural and necessary for some projects to close while others hit their stride.
The big news: the number of private sector advanced nuclear projects grew by 19% from 54 to 64 since our 2018 report, even as the overall number of projects decreased slightly (from 75 in 2018 to 71 in 2019). This shift represents an important evolution from academic research projects toward the private sector as advanced nuclear gets closer to commercialization. Other key observations:
Five companies are already working with the Nuclear Regulatory Commission to prepare for licensing, and NuScale just completed the third phase of the first ever, small modular reactor design-certification application process.
While 14 university or government-funded projects, which contributed valuable research to the field, completed their funding cycles, the number of private sector projects grew from 54 to 64.
We identified three accelerator driven system projects, one advanced nuclear fuel company, eight high temperature gas reactors, 12 liquid metal-cooled fast reactors, one microreactor, nine molten salt reactors, five nuclear battery companies, eight small modular reactors, and two super-critical reactors.
Projects are spread across 24 different states and provinces. California and Washington are home to largest number of projects with 11 and 10, respectively.
Six new companies emerged from the ARPA-E Alpha fusion portfolio, helping to form the Fusion Industry Association, which now has 19 member companies. The number of overall fusion projects grew from 19 to 22.

In T&T we have 2 power plants, Powergen at Pt. lisas and TGU at La Brea right?
So that's 720MW + 819MW respectively for a total of 1539MW.
My next question is, we won't be needing additional power plants in a hurry right? With solar power on the rise and the energy sector with reduced operations, we should be good to go for many years to come right?

Depends on how soon we can scale up Solar to meet the demand in 20 whenever.
@teems- i thought we on take or pay with TGU and Powergen?

What about wind farms on the east coast of Trinidad?
