Default Fukashima heating up again... reactor number 2

Temperature at No.2 reactor remains high

Attempts to cool the temperature in the No. 2 reactor of the disabled
Fukushima Daiichi nuclear power plant have only partially succeeded
despite the injection of more cooling water.

The temperature in the reactor has gradually risen from about 45
degrees Celsius registered on January 27th.
In the past 4 days, the temperature has climbed more than 20 degrees
to above 70 degrees.

The plant operator, Tokyo Electric Power Company began pumping more
water into the reactor at around 1:30 AM on Monday. But at 7 AM, the
temperature stood at 73.3 degrees and at 5 PM, 69.2 degrees.

The utility firm says 2 other thermometers elsewhere in the reactor
gave readings of about 44 degrees.

TEPCO says the rise in temperatures indicate that the flow of water in
the reactor may have changed direction after plumbing work, and is no
longer able to properly cool down the melted down nuclear fuel.

However, the utility says radioactive xenon has not been detected in
gases around the reactor, and that nuclear criticality is not taking
place.

The government and TEPCO announced in December that the 3 troubled
reactors at the Fukushima plant had reached a state of cold shutdown
with their temperatures below 100 degrees. But the situation inside
the reactors remains unclear.

New regulations established after the state of cold shutdown was
achieved require the utility to keep temperatures inside the reactors
below 80 degrees.
TEPCO says it will increase the amount of water being injecting into
the reactor to see if the temperature in the reactor drops.

The government's Nuclear and Industrial Safety Agency says there is a
need for a comprehensive study to determine whether the reactor is
actually in a state of cold shutdown. It says a brief reading of over
80 degrees on one of the thermometers does not necessarily mean there
is trouble in the cooling system.

Meanwhile, the Chairman of the Nuclear Safety Commission, Haruki
Madarame, says that a recurrence of nuclear criticality is unlikely.

But he criticized TEPCO and the nuclear safety agency for their
handling of the matter. He says they are failing to properly explain
the state of the reactors to the people.
