Japan Shuts Last of Nuclear Reactors
B. McPherson
In spite of assurances of safety, nuclear power stations in Japan remain vulnerable to damage from earthquakes and tsunamis.
The Tomari Nuclear Power Station shut down their reactors
for routine maintenance. There is speculation that all the nuclear power
stations may remain shut down. Japan is moving into the summer months when
demand for electricity for air conditioning soars. Nuclear power provided about
30% of that nation’s power supply before the Fukushima Daiichi disaster last
year.
Before the Fukushima disaster, the nuclear power industry
was expected to expand its production to provide 50% of the power needs over
the next 20 years. Imports of liquefied natural gas(LNG), coal and oil have
been ramped up to feed the thermal plants. Even so, there are predictions of electrical shortages throughout
the country.
"I have to say we are facing the risk of a very severe electricity shortage," said the economy, trade and industry minister, Yukio Edano, adding that the extra cost of importing fuel for use in thermal power stations could be passed on to individual consumers though higher electricity bills.

The end of nuclear power electrical production in Japan will
solve some issues – like what to do with the spent fuel, what happens in a
natural disaster – but it will create other problems. Japan was signatory to
the Copenhagen Agreement in 2009. The renewed reliance on burning fossil fuels
will increase Japan’s output of greenhouse gases, probably wrecking their
agreement with the accord. Power brownouts and blackouts may well result in the
deaths of people in their large cities due to the build up of heat in the
summer months.
Japan’s manufacturing plants may be starved of the power needed
to turn out their wide ranging goods.
As far as Japan’s dependence on “the friendly atom” for its
electrical supply, they are not in the top ten of countries relying on the
controversial generation. France leads the world with about 78% of its
electricity generated by nuclear power, nuclear waste is shipped to Russia. It
is followed by Belgium and Slovakia which get more than half their power from
nuclear and then by the Ukraine and Hungary.
The situation with the Fukushima Daiichi power station
remains precarious. Spent fuel rods have been stored in tanks 30 metres above
ground. Number four reactor contains nuclear fuel stored while that reactor was
shut down. If another earthquake hits the area, the elevated tanks may crash or
spring a leak releasing more radiation to the world than the initial discharge.
