Australia Nuclear Update

An Australian-based think tank is urging that nation to consider using thorium to power a new generation of nuclear reactors:
Australia should consider using its abundant reserves of the radioactive metal thorium to provide the nation with a vital alternative source of energy, a strategic thinktank says.

Australia's centre for strategic analysis, Future Directions International, made the recommendation in a new study on the country's future energy options released.

The study, Australia's Energy Options, says new safer and cleaner nuclear energy technologies could replace the country's reliance on oil, gas and coal for electricity.

It suggested Australia could use thorium instead of uranium to generate a new source of electricity.

"Australia holds the world's largest reserves of thorium, which could possibly fuel low-risk/low waste reactors which did not generate weapons-grade fissionable material, and which also could substantially reduce greenhouse gas emissions," Future Directions said.

The study said Australia has much to gain from looking at the nuclear issue and urged the government to carry out a review of new nuclear technologies.

IIRC, Thorium is a fertile element rather than a fissionable one. Thorium 232 absorbs a neutron and transmutes to U-233 which is fissionable. I've seen reports that claim U-233 is a better bombmaking material than U-235. According to the following link the US has tested nuclear bombs using U-233:

So much for the assertion that Thorium is not a proliferation threat. (This is no reason not to use it, let's just avoid easily refuted claims of non-proliferation.)

Can U-233 bombs be built? Yes. So could a curium-245 bomb...is it practical or advantageous? No. The gamma emissions from the U-232 contaminant make U-233 bombs a really stupid idea, even for terrorists or third-world countries.

Thorium IS the fuel of the future, and has been waiting for the reactor to use it. In my opinion, that reactor is the liquid-fluoride reactor, the safest reactor ever conceived. Learn more at:

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.

Huh?

The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.


What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…

How Nanomaterials Can Make Nuclear Reactors Safer and More Efficient

The following is a guest post from Matt Wald, senior communications advisor at NEI. Follow Matt on Twitter at @MattLWald.

From the batteries in our cell phones to the clothes on our backs, "nanomaterials" that are designed molecule by molecule are working their way into our economy and our lives. Now there’s some promising work on new materials for nuclear reactors.

Reactors are a tough environment. The sub atomic particles that sustain the chain reaction, neutrons, are great for splitting additional uranium atoms, but not all of them hit a uranium atom; some of them end up in various metal components of the reactor. The metal is usually a crystalline structure, meaning it is as orderly as a ladder or a sheet of graph paper, but the neutrons rearrange the atoms, leaving some infinitesimal voids in the structure and some areas of extra density. The components literally grow, getting longer and thicker. The phenomenon is well understood and designers compensate for it with a …

A Billion Miles Under Nuclear Energy (Updated)

And the winner is…Cassini-Huygens, in triple overtime.

The spaceship conceived in 1982 and launched fifteen years later, will crash into Saturn on September 15, after a mission of 19 years and 355 days, powered by the audacity and technical prowess of scientists and engineers from 17 different countries, and 72 pounds of plutonium.

The mission was so successful that it was extended three times; it was intended to last only until 2008.

Since April, the ship has been continuing to orbit Saturn, swinging through the 1,500-mile gap between the planet and its rings, an area not previously explored. This is a good maneuver for a spaceship nearing the end of its mission, since colliding with a rock could end things early.

Cassini will dive a little deeper and plunge toward Saturn’s surface, where it will transmit data until it burns up in the planet’s atmosphere. The radio signal will arrive here early Friday morning, Eastern time. A NASA video explains.

In the years since Cassini has launc…
