Experts doubt TEPCO's timetable for bringing nuke plant under control
Experts have called into question the feasibility of the controversial timetable unveiled by the Tokyo Electric Power Co. (TEPCO) for bringing its crippled Fukushima No. 1 Nuclear Power Plant under control.
"I got the impression that the plan is only a nonbinding target. I fear it will be fairly difficult to achieve the plan as nuclear reactors and other equipment have not been brought under full control yet," said Hidekazu Yoshikawa, professor emeritus at Kyoto University, who specializes in nuclear reactor engineering.
Kyushu University professor Kazuhiko Kudo is also skeptical about the viability of TEPCO's plan announced on April 17, which is aimed at making the reactors stable -- a process called a "cold shutdown" -- within six to nine months, with a "step one" period eyeing a steady decline in the radiation leakage dose within the next three months.
"The 'three-month' target is a best possible scenario, and whether it can be achieved or not depends on how much water the utility can prevent from leaking from the pressure vessels and the containment vessels. It is imperative to install an external system to recycle cooling water as soon as possible," Kudo said.
