A 1968 NASA film from the US National Archives explaining why the US needed a nuclear rocket and how the engine works. It also shows combined nuclear and chemical stages for a manned Mars mission.

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.

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.

A short clip showing how the Soviet Union used a nuclear explosion to extinguish a blown-out, burning gas well.

Footage of CNN reporter Omar Jimenez and his crew being arrested live on air while covering the Minneapolis protests after the killing of George Floyd. He identified himself as press and offered to move.

A Last Week Tonight segment in which John Oliver explains the US nuclear waste storage problem, including the Yucca Mountain politics. It argues the country needs a safe place to store waste.

Dave Jones of EEVblog debunks the marketing claims of the self-charging nano nuclear diamond battery from NDB Inc. He argues it is no better than existing 100uW betavoltaic batteries, with an added graphene supercapacitor.

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.

A sketch from the British sitcom Yes, Prime Minister in which Jim Hacker and the chief scientific advisor discuss the logic of the nuclear deterrent.

J. B. Rainsberger argues that large integrated tests are a scam: they are slow, fail opaquely, and give a false sense of coverage. He advocates focused collaboration and contract tests at boundaries instead.

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.

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.

The original trailer for Threads, the 1984 British TV film depicting the aftermath of a nuclear attack on Sheffield. The trailer hints at the film's bleak tone.

A Smarter Every Day episode from aboard a nuclear submarine on how the crew makes breathable air. It covers oxygen generation from seawater, oxygen candles and CO2 scrubbing with amine.

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.

Kirk Sorensen's Google Tech Talk on liquid-fluoride thorium reactors, a design that could burn nuclear waste and use thorium as fuel. It draws on Oak Ridge National Laboratory work from the 1950s and 60s.
