uranium

NileRed makes radioactive uranium glass from scratch, showing the chemistry involved and the green fluorescence under a blacklight. The video includes warnings about handling radioactive material.

Sabine Hossenfelder weighs the arguments for and against nuclear power, covering waste, fuel supply and newer reactor designs. She is skeptical that fast breeders and thorium solve the problems.

Scott Manley explains the nuclear salt water rocket, Robert Zubrin's concept of a rocket fueled by a rapid nuclear reaction in uranium salt dissolved in water. He covers its extraordinary performance and the dangers of managing it.

Sabine Hossenfelder explains how close nuclear fusion really is to break-even, and why headlines about ITER and lab milestones are misleading. She distinguishes plasma gain (Q plasma) from whole-system gain (Q total) and shows the latter is still far below one.

Kurzgesagt compares how many people nuclear accidents have killed against other energy sources. It walks through the worst nuclear accidents and puts their death tolls in context per unit of energy.

Real Engineering's Brian McManus explains Helion's approach to nuclear fusion: colliding two plasma rings, compressing them magnetically, and capturing energy directly from the changing magnetic flux rather than boiling water. It covers why this pulsed design sidesteps problems of tokamaks and laser fusion.

Jean-Marc Jancovici gives an MIT Media Lab talk on whether technology can save us from climate change. He argues from a physical view of energy that economic growth, energy use and climate impact are tightly linked.

A former fusion scientist argues why fusion power by 2040 is unrealistic, covering the physics challenges, neutron issues and optimistic company claims, with a brief note of good news.

Professor Ruzic explains modular micro-reactors: self-contained nuclear units with passive safety whose fuel lasts about 20 years. He covers their use for process and district heat and where they can compete with diesel generation.

RethinkX summarizes its report arguing that mainstream LCOE estimates are inflating a bubble in coal, gas, nuclear and hydro assets. It claims solar, wind and batteries will strand conventional energy investments.

An episode of the Well There's Your Problem podcast on the 1987 Goiania radiological accident in Brazil, based largely on the IAEA report. It goes through the event day by day.

Kyle Hill explains what nuclear waste actually is and how it is stored, arguing that the problem was effectively solved decades ago. It covers solid shielded waste and deep geological storage.

Real Engineering looks at why nuclear power plants are expensive and how their economics compare with fossil and renewable alternatives. It is based on a video from the Illinois Energy Professors.

An MIT colloquium by Dennis Whyte on power exhaust and first-wall cooling in fusion reactors, including recent innovations and the SPARC and ARC designs.

A lecture for high school seniors and college freshmen making the case for nuclear power and answering common objections. It is an overview of the channel's more detailed videos on each topic.

A roughly three-hour technical livestream Q&A on Helion Energy's fusion approach and the National Ignition Facility. It covers neutron production, shielding, energy recovery, diagnostics and why tokamaks might fare better.

Randall Munroe of xkcd answers what would happen if you swam in a spent nuclear fuel pool, and how much radiation you would receive at the surface versus at depth.

Mark Nelson of Radiant Energy Group explains how France, a leader in decarbonization through nuclear power, mismanaged its fleet, and what policy and outages threaten its future.

A short, humorous critique of Helion Energy's fusion approach, framed as a response to a Real Engineering video. It covers low reactivity, neutron production, bremsstrahlung losses and diagnostics.

Cleo Abram's explainer on whether nuclear waste is really the intractable problem it is portrayed as, looking at how spent fuel can be recycled and used. It features a collaboration with Johnny Harris.
