Subtitles in many languages, here is the long version, full introduction to the video : https://pastebin.com/17R2zuMz The accident occurred as three workers, Hisashi Ouchi, Masato Shinohara, and Yutaka Yokokawa, were preparing a small batch of fuel for the Jōyō experimental fast breeder reactor, using uranium enriched to 18.8% with the fissile radionuclide (radioisotope) U‑235 (with the remainder being the fissionable-only U‑238). It was JCO's first batch of fuel for that reactor in three years, and no proper qualification and training requirements appear to have been established to prepare those workers for the job. At around 10 35, a precipitation tank reached critical mass when its fill level, containing about 16 kilograms (35 pounds) of uranium, reached about 40 liters (11 U.S. gallons)
