Mikiko Jahn never forgot that she was no longer human, although the casual or even careful observer would hardly notice. She was what Professor Daniel Hunt once referred to as “the happy accident” (he hadn’t realized she was listening when he said it).
The Fukushima Daiichi Nuclear Power Plant disaster was a lot more severe in certain aspects than was generally known. Three technicians, including Jahn, had been trying to shutdown Reactor One when it began to meltdown. Maki Yamamoto and Kondo Hirofumi made it out just in time, but a strong aftershock knocked Mikiko off her feet. Before she could get up, the heavy safety door slammed shut and the steel door frame bent making it impossible to open, especially during the chaos of a disaster.
Thirty-three percent of Reactor One’s core melted before it could be cooled, but even the slight breach of the wall between the reactor and the auxiliary control room allowed the searing nuclear furnace to burn her body beyond recognition.
