Crunching the Numbers on Nuclear Construction and CO2

For a while now we've been seeing desperate anti-nukes making the ridiculous charge that nuclear energy contributes to greenhouse gas emissions once you add in the emissions from construction, mining and processing uranium -- this despite the fact that plenty of studies from third parties have found just the opposite.

Today, U.K.-based engineer Tim Jervis decided to crunch the numbers himself when it comes to construction, and he isn't impressed with the anti-nuke claims:
Let's be harsh again and pick 3 tonnes of CO2 for a tonne of steel. So we have another 200,000 tonnes of CO2 from the steel, or 200 million kg of CO2 from the steel to make a 1 GW nuclear power station.

Sum the steel and concrete CO2 figures: 300 million kg of CO2. If we had been conservative, that would have been 100 million kg CO2.

Energy from a 1 GW nuclear power station

If the power station produces power for a conservative 40 years, and runs for a pathetic 60% of the time (thus we're allowing for maintenance periods), the plant will deliver 210,000 million kWh of electricity.

The ratio is nearly zero

The simple ratio is 300,000,000 kg CO2 / 210,000,000,000 kWh - nearly 0.001 kg CO2 / kWh. Irrelevant.
As we've mentioned before, when it comes to many of the claim made by anti-nukes, it's a lot like dealing with the Wizard of Oz. Once you get too close, there really isn't any there there at all.

You need to get together a FAQ with all of this information, so pro-nukes can access it easily.

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…
