Globally, large
reactor designs remain the predominant technology.
Not exact matches
More exotic
designs remain on the horizon, such as
reactors powered by thorium fuel, but the AP1000 and other more conventional
designs are important for one simple reason: they are being built.
Yet it
remains to be seen whether the AP1000 will herald nuclear's next generation, especially because the
reactor is on its 18th
design revision and a couple of key safety questions
remain unresolved.
While we are disappointed with DOE's decision to exclude Holtec from the award, we
remain confident that our
reactor, the SMR - 160, has the greatest potential to triumph in a global marketplace because it is
designed to meet the highest expectations of safety and is uniquely engineered to compete economically with other sources of alternative energy in the evolving era of cheap fossil fuels.
PRISM is a high energy neutron (fast)
reactor design which uses a series of proven, safe and mature technologies to provide an innovative solution to disposition plutonium stockpiles and harness the
remaining energy potential of used nuclear fuel and surplus plutonium.
Lynas goes on, of course, to explain why he
remains in support of harnessing nuclear energy, particularly through advanced
reactor designs that don't come with the waste stream and complexity of the light - water
reactor design that dominates the industry today — overgrown terrestrial versions of the power source in nuclear submarines.
And nuclear power is just as sustainable as any other power source — even if we only use conventional nuclear fast
reactor designs, there is enough uranium in the oceans and on land (recoverable at prices that allow the fuel costs of fast
reactors to
remain the same as today — which is trivial) to last for 5 billlion years, the expected time
remaining fo our sun.
It
remains to be seen if Taylor's
reactor design will succeed in the real world.
The
reactor's steel - clad metal - alloy fuel would
remain in place for the
design's 30 - year operating lifetime.
