In addition, the grades of Plutonium (Pu) found
in residual fuel are far from ideal for the creation
of weaponry. Ideally Pu-2239 would be the
necessary ingredient for mass destruction. That
is not to say that it is completely impossible for
the most advanced weapons to use the spent fuel
found in the reactors. However, the content of Pu239 should be 88%-91% as against the reactor
grade content which is less than 81%.
Once we eliminate the threat of nuclear weapons
the main concern regarding nuclear power is
nuclear waste. Increasing interest in this alternative
power means increased volumes of radioactive
waste, difficulties in safe transportation and
containment. These difficulties lead to the debate
with regards to alternative forms of energy in
South Africa and abroad.
Renewable vs Nuclear
Considering the crisis at hand and its effect on the
economy, it’s obvious that serious consideration
towards other forms of energy is essential in
finding an adequate and sustainable solution in
South Africa. Wind and solar energy are popular
alternatives in the place of nuclear energy.

These types of energy do not deplete mineral
resources and are not a direct cause of pollution.
However, Dan Millar, Chemical Engineer at
AMEC believes that “The main reason for the
lack of considerable support for renewable
energy sources is their low efficiency and energy
production potential,” – whereas nuclear energy
is reliable and available at all times. The obvious
solution is then a combination of these types of
energy for the sake of the environment, sustainable
energy and of course, the economy.
If we are to use renewable energy alongside
nuclear energy this massive undertaking needs
to be implemented in the most efficient manner.
At the moment nuclear power seems to be our
best if not only choice. And we can all agree that
the energy crisis is undoubtedly a load worth
shedding.
