Nuclear Power Reality Check: A Note from Roy Innis

October 29, 2008 By admin

Abundant, reliable, affordable energy makes our jobs, health, living standards and civil rights possible. Remember that when you read about people losing their jobs or having to choose between heating, eating, paying the rent or mortgage, giving to charity, or covering healthcare, college, car or retirement costs.  Remember it when Congress makes more hydrocarbon energy off limits – or puts more obstacles in the path of nuclear power that generates a fifth of America’s electricity.

I recently visited nuclear power plants and a fuel reprocessing plant in France, which gets almost 80% of its electricity from uranium. And I’ve read some shockingly ill-informed claims about nuclear power and its supposed alternatives. Here are some essential facts.

1. Reliability.

Nuclear plants generate electricity over 90% of every year, shutting down only occasionally for maintenance, repairs and changing fuel rods. Wind turbines can be relied on just 30% of the time, on average – and just 10% of the time during hot summer days, when air conditioners are on high, but there’s barely a breeze.

2. Operational safety.

Three Mile Island was the “worst accident in US history.” But it injured no one and exposed neighboring residents to the radioactive equivalent of getting a CT scan or living in Denver for a year. It led to major improvements in nuclear plant management, operation and training.

The Chernobyl disaster was due to its shoddy design, construction, maintenance and management. According to the World Health Organization, “fewer than 50” people died as a direct result of this massive meltdown and fire, and nearly all were employees and rescue workers.

3. Storage of used nuclear fuel.

The Energy Department spent 25 years and $10 billion studying the Yucca Mountain site in Nevada, before concluding that it will meet all safety standards. In fact, the largest expected annual radiation dose for someone living near this geologically stable site would be less than 1 millirem – compared to 1,000 millirem from an abdominal CT scan.

America’s 104 nuclear plants generate enough electricity for nearly 75,000,000 homes – and produce about 2,000 tons of “spent” uranium fuel annually. So Yucca will be able to hold all the used fuel from the past 50 years, plus another 35 years of used fuel, without expanding on the original design.

Spent fuel and other wastes (high-level defense wastes, plus low-level wastes like protective clothing) are solid materials. There is no liquid that can leak into rocks or groundwater. Liquid wastes, like water used in reactors, are treated and reused.

4. Transportation safety.

Shipping containers are constructed from layers of steel and lead, nearly a foot thick, and carried on trucks or rail cars. (The 25 to 125-ton containers are too heavy to go in airplanes.) They’ve been slammed into concrete walls at 85 mph, dropped 30 feet, burned 30 minutes in 1475-degree fires, and submerged in water for hours. They haven’t broken or leaked.

Over 3,000 shipments of spent fuel have traversed 1.7 million miles, with no injuries, deaths or environmental damage. Only one significant accident occurred. A semi-truck overturned while avoiding a head-on collision, and the trailer and attached container crashed into a ditch. No harmful releases of radioactivity ever occurred.

That hasn’t stopped imaginative writers from saying “catastrophic” accidents could put “millions” of Americans at risk of exposure to “deadly radiation” or even death, especially if an airplane crashed a cargo of nuclear wastes into a city. They’ve been watching too many Hollywood movies, where every car accident becomes a raging inferno.

5. Theft and terrorism.

The notion that spent (or even fresh) power plant fuel could be stolen and turned into a powerful bomb is likewise more Hollywood than reality.

Those pesky little atomic numbers and enrichment levels are confusing, but important. Weapons grade materials are plutonium, uranium 233 and highly enriched (better than 20%) U235. Power plant fuel is slightly enriched (under 4%) U235. Spent fuel is U238, which cannot cause a chain reaction.

Turning spent fuel into a bomb would require sophisticated reprocessing facilities, which terrorists are unlikely to have. Even a “dirty bomb” (radioactive materials around a non-nuclear explosive) would cause more fear than actual damage. And the US nuclear industry’s commitment to safety applies to plant design and management, shipping and storing wastes, and guarding against theft and terrorism.

The bottom line? We need the electricity that nuclear power provides, and we can get it safely. Just try to imagine life without all the things that require electricity. Remember the pain, inconvenience and financial losses you or people you know suffered when storms or blackouts knocked out the electrical power.

Consider the warnings of experts: We are dangerously close to experiencing major brownouts and blackouts in many parts of the United States, especially in our western states, because we haven’t built the power plants and transmission lines we need for a growing population that depends on electricity 24/7/365.

We need to conserve more, install more insulation and better windows, and use more efficient light bulbs, computers, servers, heaters and air-conditioners. We need more wind and solar power, where those sources make economic, practical and environmental sense. But we also need a lot more affordable, reliable electricity from nuclear power plants.

Ponder how far our heating, cooling, communication and other technologies have come in just 100 years – and where we’re likely to be 50 or 100 years from now. However, we’re not there yet.

Futuristic technologies – like solar generators orbiting above the Earth, beaming electrical power to urban receivers – for now are pure science fiction. They’ll be reality about when Scotty beams Captain Kirk back to the Enterprise. We need to work on them. But we need real energy for real people, today.

Otherwise, homes, factories, offices, schools and hospitals will go dark. Bread winners will go jobless. Energy prices will soar even higher. Families won’t have basic necessities, much less luxuries. And poor and minority citizens will see civil rights gains rolled back, because only energy and a vibrant economy can turn constitutionally protected rights into rights we actually enjoy.

Carbon tax is just tilting at windmills: Gary Johns

October 27, 2008 By admin

A carbon tax will not stop the need for climate adaption. Even under the Australian Greens’ scenario for a carbon-free economy, climate change will occur but the economy would be less able to afford to adjust.  Read more here.

On a Mission to a Low-Carbon Economy: Penny Wong

October 16, 2008 By admin

We have a “moral” duty to tackle climate change and won’t delay action because of the world economic meltdown, a defiant Australian Climate Change Minister Penny Wong told the prestigious London School of Economics last night.  [Read more…] about On a Mission to a Low-Carbon Economy: Penny Wong

Jennifer Visits the Australian Parliament

October 15, 2008 By admin

Stewart Franks, Bob Carter and I gave a presentation at Parliament House on Monday evening on Climate Change.  Professor Carter focused on global temperatures, I followed with some rainfall graphs for different parts of Australia, and then Associate Professor Franks explained why rainfall along the east coast of Australia is so variable and dominated by either El Nina or La Nina cycles back at least as far as 1660.

Our main message was that there is no climate crisis, but that climate change is a natural hazard.  

The event was organised by the office of Dennis Jensen MP.  Dr Jensen is the member for Tangney in Western Australia. 

Shadow minister, Nick Minchin, and former opposition leader, Brendan Nelson, both attended and are pictured with me at Parliament House on Monday evening.

World Food Day 2008

October 15, 2008 By admin

Tomorrow is the United Nation’s “World Food Day” and the focus is on the pressing need for the world to adapt to climate change. But even before “climate change” became a political concern, the poor have been unable to deal effectively with drought, storms and flooding.

Now government programmes in the name of climate change have already had terrible results – more than US$ 11 billion worth of subsidies were used to turn food crops into biofuels last year. This contributed substantially to the rise in food prices that helped push 75 million more people below the hunger threshold.

There is a case for government to provide flood defences and other collective goods, but most adaptation will occur at a much more local scale and as such is best left to individuals.

In a new report, world-renowned agricultural economists Professors Douglas Southgate and Brent Songhen point out that farmers will likely adapt to global warming by switching crops, and adopting new technologies and farming methods – just as they have done for centuries. 

The launch of the report, Weathering Global Warming in Agriculture and Forestry by Douglas Southgate and Brent Sohngen (November 2008, International Policy Network), coincides with World Food Day and can now be downloaded here.
