Probe Into Fukushima No.2 Reactor Hits Snag
Nuclear & Energy Aug. 4, 2015 - Updated 22:56 UTC-4
Sources
familiar with the decommissioning process at the Fukushima Daiichi
nuclear plant say efforts to determine the state of molten fuel in the
reactors have hit another snag.
They say 2 new devices developed at a
cost of more than 4 million dollars to take X-ray-like photos inside
the No.2 reactor are too big to install.
The Japanese government and
the plant operator, Tokyo Electric Power Company, devised the machines
so that they use elementary particles called muons to see through hard
surfaces and map the spread of fuel inside.
They planned to start capturing images as early as this fall.
But
they found the 8-by-8-meter devices will not fit the No.2 reactor
building site unless they remove and decontaminate other equipment
first. They believe that would hinder the decommissioning process. It
would also cost twice as much money as they spent creating the devices.
Workers
have been using muon detectors at the No.1 reactor since February. The
devices meant for the No.2 reactor were designed to capture images with
higher resolutions.
The government and TEPCO will divert the machines
at the No.1 reactor to the No.2 reactor as early as year-end. They say
if it is a success, they may abandon the plan to use the new devices.
TEPCO
has also postponed plans to send a robot probe into the No.2 reactor in
August to investigate the molten fuel due to problems with the
preparations.
Fuel rod casings found damaged by debris
Nuclear & Energy Aug. 4, 2015 - Updated 04:02 UTC-4
Workers
at the crippled Fukushima Daiichi nuclear plant have been preparing to
remove hundreds of fuel rod assemblies from a pool of the facility's No.
3 reactor building.
The workers have found damaged fuel rod
containers after removing a device that had fallen on them during the
2011 disaster. They're now checking whether the damage will affect their
plan to remove fuel from the pool.
A 20-ton device for moving fuel
rods in and out of the pool on the building's top floor was removed on
Sunday, more than 4 years after the nuclear accident. High radioactivity
prevented workers from carrying out the removal smoothly.
The plant's operator, Tokyo Electric Power Company, checked the condition of 566 fuel rod assemblies in the pool.
Workers
found that the metal casings of 4 assemblies had been distorted and
have twisted handles. This is evident in images released by the
operator. It says the fuel rods appear undamaged, as radiation levels in
the pool have shown no irregularities.
The utility is checking for other damage and studying how to remove the distorted casings from the pool.
Removing
fuel rod assemblies from spent fuel pools is an important part of
decommissioning work at the plant. ore than 1,500 assemblies are still
in pools at 3 of the facility's reactor buildings.
