Tepco’s
Typhoon measures to prevent contaminated water overflowing entirely
messed up
23
October, 2013
Two
more Typhoons are coming to hit Japan from this weekend.
Having
11 tank area dams overflow on 10/20/2013 even in the normal rain,
Tepco is trying to prevent the mixture of rainwater and contaminated
water from overflowing due to the next Typhoons.
However
the back-up tanks of 4,000 m3 capacity is nearly full already. Tepco
has to rely on the underground reservoirs that leaked contaminated
water this April.
On
10/23/2013, they released the map of water transferring between the
tank area dams and the back-up reservoirs, but it looks shockingly
unorganized (The image below).
They
are going to introduce additional tankers and fire-engine but it is
not known if they can control the water sufficiently.

eyes fuel removal from Fukushima reactor 4 pool in early November
The
process, to continue until the end of next year, will mark a new
stage in the decommissioning of the reactors 1 to 4, which were
severely damaged in the nuclear crisis triggered by the March 11,
2011, mega-quake and tsunami.

Reactor
4 unit was the only one of the four not to experience a meltdown
because its fuel had been in the spent-fuel pool during maintenance
work. But there is concern over the continued storage of the more
than 1,000 fuel assemblies in the pool, which is located inside a
reactor building that suffered a hydrogen explosion.
Tepco
had planned to begin the process from mid-November, but it has nearly
completed preparations, including the installation of a crane to
remove the fuel.
If
the safety of the equipment is confirmed by the Nuclear Regulation
Authority, Tepco will start taking out the fuel.
The
fuel will be placed in containers and taken to what has been called a
common pool in a different building about 100 meters away that is
expected to provide more stable conditions for keeping the fuel cool.
The
reactor 4 spent-fuel tank currently contains 1,331 spent fuel
assemblies and 202 unused ones. Tepco succeeded in taking out two
unused fuel assemblies in a trial last year.
The
challenging task will be carried out along with the ongoing fight to
contain the spillage of massive amounts of highly radioactive water
accumulating at the plant as a result of continuing water injections
into the crippled reactors 1, 2 and 3.
Tepco
said Wednesday that it detected 59,000 becquerels per liter of beta
radiation, emitted by radioactive substances including strontium, in
water taken from a drainage channel near a storage tank that was
found to have leaked 300 tons of highly toxic water in August.
The
water sample, extracted the previous day, showed a record-high
figure. To prevent the radioactive water inside the channel from
flowing into the Pacific, Tepco has placed sandbags at a downstream
section.
Tokyo
Electric Power Co. plans to start removing nuclear fuel from the
spent-fuel pool at the top of the reactor 4 building at the crippled
Fukushima No. 1 plant as early as Nov. 8, about a week earlier than
scheduled, sources close to Tepco said Wednesday.
