Part of this does not even need a new reactor. France has recycled used fuel at La Hague for decades and burns the recovered plutonium as MOX in its existing fleet. Fast reactors are the next step, burning the long-lived actinides too

From the policy paper.
Furthermore, in order to reduce the lifetime of the minor actinides from 100,000s years to 100s years, at least three cycles of separation, refabrication and burning would be required, dependent on the specific process. Significant pause periods, likely decades, would be required after each burning step to allow heat, radiotoxicity and the presence of a number of specific problematic isotopes to reduce such that fuel manufacture is possible, even with advanced remote handling techniques.

Professor Thomas Albrecht at the Colorado School of Mines is giving his Inorganic Chemistry Division Seminar: High-Pressure Routes to Redox with Lanthanides and Actinides on Wednesday, November 4 at 11:30 AM (CT) in CHEM 2104. Join us!
Seminar flyer with ATM logo, abstract, and maroon sidebar with photo of Dr. Albrecht and biosketch. Abstract text: Elements beyond plutonium are rich testbeds for probing how relativistic effects alter electronic structure and hence molecular structure, physical properties, and reactivity. Americium, curium, berkelium, californium, and einsteinium are the final elements for which bulk properties such as X-ray diffraction, optical spectroscopy, and magnetism can be measured, albeit with great difficulty. This lecture focuses on pushing the boundaries of chemistry deeper into the periodic table especially through the application of extreme conditions to complexes and materials containing transplutonium elements. These measurements have proven to be well worth the effort and have revealed evidence for a break in the fundamental properties of actinide elements that starts in the actinide series at californium and strengthens through einsteinium, fermium, and mendelevium. The evaluation of these experimental results with relativistic quantum mechanical theory has helped to explain these unusual observations. Biosketch: Thomas Albrecht is a University Distinguished Professor and Director of the Nuclear Science and Engineering Center at the Colorado School of Mines. He is also jointly appointed as a Scientist at Idaho National Laboratory and Los Alamos National Laboratory. He is a Fellow of the Royal Society of Chemistry and the AAAS and winner of several American Chemical Society awards including the Glenn T. Seaborg Award for Nuclear Chemistry as well as the American Crystallographic Association, M. J. Buerger Award. His research interests focus on the chemistry, physics, and materials science of radioactive elements, especially heavy elements like berkelium and californium. Professor Albrecht received his Ph.D. in Chemistry from Northwestern University and was a postdoctoral fellow at the University of Illinois.

Fun fact, lui bon plus ne les connaissait pas tous !
Mais son classement était si bien pensé que ceux qu'ils ne connaissaient pas se sont bien intégrés.

Bon, faut rentrer à la truelle les actinides et les lanthanides😁

But apparently, the 1st 4 actinides can shift these 2 orbitals. Thorium isn't entirely alone in this, but it's the most extreme in breaking the Aufbau prediction by skipping the predicted shell entirely, and therefore, chemically, it acts more like a transitionmetal.

I need to review the lanthinides and actinides more I forgot that Dysprosium even existed and had to look it up

I've been getting back into my hobbies and I would love to needlepoint the periodic table of elements because I think neon being a neon color and maybe doing all of the actinides in glow in the dark thread would be fun... but I have no where to put it so it's just another idea.

New nuclear costs more, not 100×. Wind/solar LCOE is often ~2–5× cheaper per MWh. Nuclear runs ~90% of the time; solar ~20–25%. Same dollars buy less firm power once storage is counted. Spent fuel can be recycled (France does); most mass is reusable making column and long-lived actinides drop a lot

If your trivia game asks for an element and then rejects actinides, I'm probably not going to keep playing your trivia game.

The powerups being actinides is the only thing that makes sense to me.

Il explique que les déchets nucléaire ne seront plus dangereux dans quelques centaines d'années,
La réalité : demi-vie du plutonium 239, 24 100 ans, 240000 ans pour qu'il ne soit plus dangereux
certains actinides mineurs restent même actifs sur des millions d'années.
