[Report 427] Wednesday, May 23

We have been reporting a status of Fukushima Daiichi nuclear power station by

summarizing news aired by NHK, which is Japanese national broadcasting company.

We regard it as most credible news among many news sources and we are happy to say

that NHK’s English website has gotten enriched and now you can see movies and

English scripts at http://www3.nhk.or.jp/daily/english/society.html.

Given this situation, we decide to simply place these scripts as it is for the record in case

that it will be deleted from the website later, rather than summarizing news as we did.

●Fukushima reactor vessel may be leaking water

Japanese scientists say cooling water may be leaking from a second reactor at the

Fukushima Daiichi nuclear plant. They say the water level of the reactor's

containment vessel is much shallower than previously thought.

Researchers at the government-backed Japan Nuclear Energy Safety

Organization analyzed the internal pressure and other data from the No.1 reactor.

They say the water in the vessel is about 40 centimeters deep. The plant's

operator, Tokyo Electric Power Company, says the water should have a depth of

about 2 meters.

They say water may be leaking from a hole in a pipe 40 centimeters from the

bottom of the vessel. The pipe is connected to the suppression chamber below.

The hole is estimated to be 2 centimeters across.

The power company says that despite the low water level, the nuclear fuel in the

vessel is sufficiently cooled at about 30 degrees Celsius.

In March, the utility used an endoscope to find that the water level inside the

No.2 reactor had fallen to 60 centimeters.

The water leaks at the two reactors could make the task of decommissioning the

plant more difficult. The utility plans to fill the containment vessels with water to

remove melted fuel.
