Nuclear Power
Experts believe that new technology will make nuclear fuel an increasingly important source
of energy in the years ahead. More than 100 nuclear power plants in the United States
already provide about 20 percent of our electricity. Globally, that figure stands at 16 percent. Unlike coal and oil, nuclear power does not release carbon dioxide that contributes to
global warming. One form of nuclear energy, still a dream, offers the prospect of turning
the world’s oceans into a new source of fuel. That, of course, is nuclear fusion. Abundant
supplies of its fuel — deuterium — exist in the world’s oceans. Nuclear power also promises
many countries increased energy security, with reduced dependence on imported oil.
“The global utilization of nuclear energy has come a long way from its humble beginnings.
But the effective utilization of nuclear power will require continued improvement in
nuclear technology, particularly with regard to safety and efficiency. The projected growth
in nuclear power has focused increased attention on the development of advanced materials, fuels, waste forms, and separations technologies. In all of these areas, the performance of materials and chemical processes under extreme conditions is a limiting factor.”
That was Dr. James B. Roberto, deputy director for science and technology at Oak Ridge
National Laboratory in Tennessee. Dr. Roberto reported on nuclear energy at the ACS
spring 2008 national meeting in New Orleans. Scientists and engineers are responding to the
challenges that have limited use of nuclear energy in the United States. For instance, a new
generation of so-called “inherently safe” nuclear reactors are moving from design to reality.
And the United States is moving ahead in addressing thorny problems such as how to deal
with spent nuclear fuel and nuclear waste. Here is Dr. Roberto:
“Chemists are heavily involved in addressing this challenge and in the future of nuclear
energy through research on advanced fuels and waste forms. This is a scientific challenge of enormous proportions with broad implications for materials science and chemistry. Addressing this challenge provides an opportunity to revolutionize the science and
technology of advanced nuclear energy systems for a brighter, more sustainable future.”
Conclusion
Revolutionizing science and technology. Addressing great challenges. Fostering a brighter
and more sustainable future. Dr. Roberto’s words go to the very heart of this series of
podcasts. Please join us at ACS for the next chapter in this ongoing saga of chemistry for
