Solution to combat particle dispersal to be tested at Japan plant
By the CNN Wire Staff
March 30, 2011 1:03 p.m. EDT
Tokyo (CNN) -- Tokyo Electric Power Co. will begin spraying a liquid aimed at preventing the dispersal and scattering of nuclear particles in and around the Fukushima Daiichi plant, the company said Wednesday.

The spraying, on a trial basis, will begin Thursday and is dependent on acceptable radiation levels for workers, Tokyo Electric said in a statement. The liquid is said to be able to stick to nuclear particles when it dries -- and will also stick to other particles, such as dust.

One of the liquid's main components is a water-soluble synthetic resin called Kuricoat C-720G, which will be mixed with water before spraying. The resin, which envelops nuclear particles, is also used in glue, the company said. It is manufactured by a Japanese company....

On approximately 5:56 pm, March 30th 2011, TEPCO employee discovered smoke
generation from power panel (*)at the turbine building Unit 1 (Reactor cold
shoutdown). On 5:57 pm, March 30th 2011, TEPCO immediately reported this
incident to the fire department.

Subsequently the fire department consisting of TEPCO employee inspected the
area. On approximately 6:13 pm, March 30th 2011,we confirmed the smoke
generation stopped after interrupt electrical supply to the power panel.

From now, the fire department will conduct inspection around the area.

TEPCO will also conduct an investigation into a cause in detail.
This incident will not cause any effect of radiation externally.
(Previously announced on March 30th, 2011)

On 7:15 pm, March 30th 2011, the fire department made a judgmental decision
that this incident was caused fault of the power panel, they found no signs
of fire.

Press Release (Mar 31,2011)
The detection of radioactive materials in the water on 1st basement of turbine building at the site of Fukushima Daiichi Nuclear Power Station


On March 28th 2011, we received advice from Nuclear Safety Commission of
Japan to conduct sampling survey of the water on the first basement of
turbine building of Fukushima Daiichi Nuclear Power Station as well as to
reinforce the sampling survey of seawater in order to secure safety and to
monitor the leakage of the water on the basement into underground and/ or
sea.

On March 30th, 2011, we conducted nuclide analysis of radioactive
materials, the sample of which was collected from the water on 1st
basement (sub drain) of turbine building at the site of Fukushima Daiichi
Nuclear Power Station. Because radioactive materials were detected as a
result, as shown in the attachment, we reported the result to Nuclear and
Industry Safety Agency as well as to the government of Fukushima
Prefecture today.
