now just like the light beam swords or
lightsabers we see in science fiction
movies researchers here in South Korea
have found a way to cut through thick
metals using lasers however unlike the
movies the technology will be put to
rather more mundane use shall we say
helping in the dismantlement of nuclear
power plants park se-young with more
it's been eight years since the
Fukushima disaster in Japan yet most
facilities there have been left
unattended due to the remaining
radiation is difficult to dismantle the
plant but now Korean researchers have
developed fiber-optic laser technology
to come materials at nuclear power
facilities the laser technology is
advantageous for motor control and can
reduce decommissioning waste disposal
costs of secondary waste dismantling
nuclear power plants requires cutting
down large facilities removing
radioactive contamination and restoring
the plants to their original environment
however internal parts of the reactor
are made of thick metal like stainless
steel and carbon steel which are
difficult to cut and generate lots of
secondary waste the new technology can
cut up to one hundred millimeter thick
metal underwater and is four times more
efficient compared to existing
technology our technology is superior to
the global technology standards we can
apply it to the dismantlement of
domestic nuclear power plants and
compete in the global market the study
was published in six international
journals in the field of lasers Axio
