I’ve heard that there are plans to build a large repository for nuclear waste in Yucca Mountain in Nevada, but that plans have been slow and are very controversial. Where is our nuclear waste kept now and what dangers does it pose? — Miriam Clark, Reno, NV
Plans to store the majority of our nation’s spent nuclear fuel and other highly radioactive waste at a central repository underneath Yucca Mountain in the Nevada desert 80 miles from Las Vegas were first hatched in the mid-1980s. But the project has languished primarily due to opposition from Nevadans who don’t want to import such dangerous materials into their backyard. Critics of the plan also point out that various natural forces such as erosion and earthquakes could render the site unstable and thus unsuitable to store nuclear isotopes that can remain hazardous to humans for hundreds of thousands of years to come.
But the Bush administration is keen to jump-start the project and recently submitted a construction license application to develop the facility—which when completed could hold up to 300 million pounds of nuclear waste—with the federal Nuclear Regulatory Commission (NRC). In announcing the filing, Secretary of Energy Samuel Bodman said that the facility being proposed can “stand up to any challenge anywhere,” adding that issues of health safety have been a primary concern during the planning process.
But the administration has still not submitted a crucial document declaring how protective the facility will be with regard to radiation leakage. Bush’s Environmental Protection Agency concluded that the facility needs to prevent radiation leakage for up to 10,000 years. But a federal judge ruled that to be inadequate and ordered the administration to require protection for up to one million years. The White House argues that the NRC should press on with its review process and that the standard can be settled on later.
Currently, without any central repository, nuclear waste generated in the U.S. is stored at or near one of the 121 facilities across the country where it is generated. Nevadans like Democratic Senator Harry Reid, who has doggedly opposed the Yucca Mountain repository, say it makes more sense to leave such waste where it is than to risk transporting it across the nation’s public highways and rail system, during which accidents or even terrorist attacks could expose untold numbers of Americans to radioactivity.
But others say that the current system, or lack thereof, leaves Americans at great risk of radioactive exposure. The non-profit Nuclear Information and Resource Service concluded in a 2007 report that tons of radioactive waste were ending up in landfills and in some cases in consumer products, thanks to loopholes in a 2000 federal ban on recycling metal that had been exposed to radioactivity.
As with all issues surrounding nuclear technology, where and how to dispose of the wastes is complicated. While some environmental leaders now cautiously support development of more nuclear reactors (which are free of fossil fuels) to help stave off climate change, others remain concerned that the risks to human health and the environment are still too high to go down that road. Whether or not the NRC approves plans for Yucca Mountain won’t resolve the larger debate, of course, but perhaps the greenlighting of other promising alternative energy sources could ultimately make nuclear power unnecessary altogether.

Summer’s going to be a scorcher this year, and I’d like to know how I can keep cool indoors without just running my energy-hogging air conditioners all the time. Any tips?
— John McGovern, Cohasset, MA
According to Harvey Sachs of the non-profit American Council for an Energy-Efficient Economy, the movement of air over the skin is what’s key to keeping the body cool. So instead of turning on that A.C., see which direction the breeze is blowing outside (no matter how minimal it may be), and then open a few windows strategically to try to get it flowing through the house from end-to-end or side-to-side.
If the breeze alone isn’t enough, apply some fan power. Even small tabletop fans, which can be had for $30 or so at Target and similar stores, can really whip the air around. Placing one facing in by the window where air is coming in, and one at an opposite window positioned to blow warm air out, can create a nice “wind tunnel” effect in pulling air through the house.
This strategy can be especially effective at night when it is cooler. But then it’s important to shut the windows when you leave for the day in the morning to keep the cooler air in and the warmth of the new day out. Keep blinds shut and curtains drawn, too, as sunlight pouring into the house only creates more heat. And remember that lights left on are not only wasting electricity—they’re creating heat, as well.
Ceiling fans also do a nice job of circulating air in the rooms you occupy most, and though they do require some up-front costs for installation they use only about 1/30th the electricity of a room air conditioner.
Beyond moving the air around to keep cool, the website WikiHow.com lists several tips for using water to keep cool sans AC. One tried and true method is to wet your wrists and other pulse points with cold water, and then keep those spots cool by holding an ice cube wrapped in a face cloth against them. The relief is immediate, and this method will cool down the entire body—by as much as three degrees Fahrenheit—for upwards of an hour. Another WikiHow suggestion: Wear a short-sleeved shirt and keep the sleeves wet with cold water (from a squirt bottle, faucet or hose). Keeping the pant legs of long pants wet is also a good way to keep your legs cool. Add in a breeze or a fan, and you can actually get cold.
Of course, if you just can’t live without air conditioning, there are greener options out there. For starters, a single window unit that keeps one room cool is far less energy intensive and polluting than central air conditioning that keeps all the rooms in the house (including those you’re not using) cool. Look for new models sporting the federal Energy Star label, which marks units as energy efficient.
Another option for those in hot, dry climates is an evaporative cooler, which cools outdoor air through evaporation and blows it inside the house. These units make for a nice alternative to traditional central air conditioning, as they cost about half as much to install and use only one quarter of the energy overall.
