AFP, Nov. 18, 2013: Hiroaki Koide, assistant professor at Kyoto University’s Research Reactor Institute, said the timing of the fuel rod removal [at Fukushima Unit 4] was crucial as “the reactor’s storage pool is in an unstable condition”.
Kyodo News, Nov. 18, 2013: [...] the condition of the spent fuel pool on the highest floor of the crumbling building was a major source of concern [...]
AFP, Nov. 18, 2013: [...] the damage to the building housing this pool [...] is a wildcard that will complicate this operation considerably
AP, Nov.18, 2013: [...] experts say keeping so many fuel rods in a storage pool in the building still poses a major safety risk. [...]
Reuters, Nov. 18, 2013: Moving them is urgent because they are being stored 18 meters (59 feet) above ground level in a building that has buckled and tilted and could collapse if another quake strikes.
Businessweek, Nov. 8, 2013: Engineers have been examining the stability of the reactor building to make sure no new vulnerabilities have developed that could lead to accidents during removal. Quarterly tests have also been conducted to ensure the building isn’t sinking because of soil subsidence, Ono said.
Radio Free Europe, Nov. 18, 2013: “The situation has degraded. They are not able to cope with the situation and to invent and develop concepts that sustainably stabilize the site” [said nuclear consultant Mycle Schneider.]
