Experts particularly concerned about weight of fuel in No. 4 pool in building with possible quake damage — Destruction blamed on Reactor No. 3 explosion
Title: Another Look at the Inside of Tepco’s Fukushima Daiichi Nuclear Power Plant
Date: Feb 20, 2012
Reactor No. 4 appeared badly damaged but Tepco officials blamed that on the force of the explosion at No. 3.
A dozen or so workers could be seen on the roof of that building. That’s near the location of the reactor’s spent-fuel pool – the pool of water where nuclear fuel rods are stored when they’re not active in the reactor.
Since unit 4 had been undergoing major maintenance at the time of the disaster, all the reactor’s fuel rods were in the pool for storage, making it a particular concern for experts worried about the weight of the fuel in a building that may have been damaged by the magnitude 9 earthquake last March.
