Nuclear is not the right alternative energy source
Arjun Makhijani: Nuclear is not the right alternative energy source
New plants are risky, costly and unnecessary, says ARJUN MAKHIJANI12:00 AM CST on Tuesday, February 26, 2008
Luminant Energy, formerly TXU, is proposing to build two Mitsubishi nuclear power reactors at its Comanche Peak site, where two reactors are already in place.
This is part of a national wave of new commercial reactor proposals after a three-decade lapse in new orders – eight in Texas alone. Having failed miserably to deliver on the 1950s promise that nuclear electricity would be "too cheap to meter," the industry now says it will save us from climate change. If you don't like coal, you have to take nuclear, goes the nuclear establishment's hopeful mantra.
That's a false choice. Replacing coal with nuclear is risky, costly and unnecessary.
Renewable energy sources are quite sufficient to provide ample, reliable electricity. For instance, Texas has greater wind energy potential than its present electricity generation from all sources; it is greater also than the output from all U.S. nuclear power plants combined. And it has barely captured a whisper of its potential.
Wind energy is competitive with or more economical than nuclear energy – about 8 cents per kilowatt-hour in good areas. A recent independent assessment by the Keystone Center, which included industry representatives, estimated nuclear costs at 8 to 11 cents.
Intermittency is not a significant issue until very high levels of penetration. For instance, a 2006 study prepared for the Minnesota Public Utilities Commission found that an increase of just over 2 percent in operating reserves would be sufficient to underpin a 25 percent renewable energy standard supplied by wind.
Meanwhile, Solar energy is somewhat more expensive today, but costs are coming down rapidly. Last December, Nanosolar produced the first solar panels costing less than a dollar a watt at its factory in Silicon Valley.
In January, MidAmerican Energy Holdings, which is owned by Warren Buffet's Berkshire Hathaway, dropped plans to build a nuclear power plant in Idaho, on the grounds that it could not provide reasonably priced energy to its customers.
New nuclear plants would add to the country's problem of nuclear waste. The federal government has long been in default of its obligations to existing nuclear plant operators to take the waste away from their sites. Nuclear utilities have had to take the government to court to recover added storage expenses, which will cost the taxpayers billions or possibly even tens of billions of dollars over time.
To imagine that the federal government will take charge of waste from new plants where it does not even have contracts is wishful thinking. Much more likely, Texas will be stuck with it.
And then there is the problem of cooling water. The two proposed reactors would consume about 40 million gallons of water per day. Even assuming that the water is available, Texas is risking a less reliable power system, given that droughts are estimated to become more extreme in a warming world.
For instance, last September, a nuclear unit at Browns Ferry belonging to the Tennessee Valley Authority had to be shut down for lack of water. In contrast, solar photovoltaics and wind-generated electricity do not need water.
Luminant's two reactors are already discharging significant amounts of tritium-contaminated radioactive water into the Squaw Creek reservoir. New reactors would only add to those discharges.
Before proceeding with new reactor proposals, Luminant should at least investigate how it might reduce existing tritium discharges. Tritium is radioactive hydrogen, which displaces ordinary hydrogen in water to form tritiated water, which becomes radioactive as a result.
The notion that renewable energy cannot supply the electricity requirements of the United States has been widely put forward without careful technical evaluation.
On the contrary, it is nuclear that is the risky course. Texas can remain an energy leader in the twenty-first century – but only if it steps out ahead of the coming renewable energy revolution.

State might end nuclear plant ban
Bills would ease waste restrictions
By James Bruggers

The Courier-Journal
FRANKFORT, Ky. – Three state legislators are trying to overturn a nearly-quarter-century ban on nuclear power in Kentucky, as the nuclear industry vies for a comeback.
Two companion bills -- one in the Senate, the other in the House -- would remove a requirement stipulating that before any nuclear plant is built, there must be a permanent disposal facility to handle its radioactive waste.
The existing law effectively puts a moratorium on nuclear power in Kentucky, since there is no permanent disposal facility in the United States. The federal government has been studying locating one at Yucca Mountain in Nevada for more than two decades.
But the legislation by Sens. Bob Leeper, I-Paducah, and Charlie Borders, R-Russell, and Rep. Steven Rudy, R-West Paducah, would allow nuclear power plants in Kentucky as long as they have a waste-disposal plan that complies with federal law, such as securing the waste at the plants. The waste remains dangerous for thousands of years.
Leeper and Borders both acknowledged that the bill could help constituents involved in the nuclear fuel industry, but they also said they are looking to help the nation and Kentucky diversify their energy supplies.
Both said they know of no plan by any utility to propose a nuclear power plant in Kentucky.
Leeper's Western Kentucky district includes the Paducah Gaseous Diffusion Plant, the nation's only source of fuel for nuclear power plants. Some residents of Borders' northeastern Kentucky district work at the Paducah plant's sister facility in Piketon, Ohio, where a replacement to the aging Paducah plant is under construction.
"Given the national discussion on energy … there is some recognition that a certain portion of our (energy) production is going to be nuclear," Leeper said. "This bill is an attempt to relax that moratorium so rather than be a state that's marked off, anybody looking into this could keep us on a list."
A spokeswoman for USEC Inc., which operates the Paducah and Piketon facilities, welcomed introduction of the bills but said the company did not request them.
"We are pleased to see any activity that provides for the advancement of additional deployment of nuclear power in the United States," said USEC's Georgann Lookofsky. "While this legislation has no near-term impact on any activity or project involving USEC, we applaud the intent of Sens. Leeper and Borders to remove barriers to the expansion of Kentucky's role in nuclear power as an important part of the nation's energy mix."
One of the state's biggest utilities -- Louisville-based E.On U.S., which owns LG&E and Kentucky Utilities -- is neutral on the bill, said spokeswoman Chris Whelan, but she acknowledged that E.On advocates for more nuclear power in Europe.
Gov. Steve Beshear's press office would not say what the governor thinks of the two bills.
"All we can say right now is we will monitor the legislation's progress," said Beshear's spokesman, Dick Brown.
The Senate bill was assigned to the Agriculture and Natural Resources Committee on Wednesday.
The bills were opposed last week by Tom FitzGerald and his Kentucky Resources Council, an environmental advocacy group.
FitzGerald said he welcomes a policy discussion concerning "what role if any" nuclear power should play in the state. But he said the council cannot support a revision of state law that would allow indefinite on-site storage of nuclear waste.
Moratorium established in 1984The General Assembly passed its moratorium in 1984. News reports in The Courier-Journal at the time said the legislation reflected growing anti-nuclear sentiment, in part because of controversies involving the recently canceled Marble Hill nuclear power plant near Madison, Ind., which was abandoned by the former Public Service Indiana after $2.8 billion was spent.
By taking that action, the legislature also was reflecting Kentucky's abundance of coal, said Bill Caylor, president of the Kentucky Coal Association.
The state is the third-largest producer of coal in the nation and gets more than 90 percent of its electricity from it.
But many scientists now identify coal as a major source of the pollution that's heating up the atmosphere. Congress is getting closer to mandating greenhouse gas cuts. All three leading presidential candidates are promising to do the same.
Some national environmental organizations now are bucking a long-held opposition to nuclear power and are willing to consider it as part of a solution to global warming. That's because nuclear plants don't emit carbon dioxide, one of the leading greenhouse gases.
"The scope of the problem requires us to look at all of the options," said Tony Kreindler, spokesman for the group Environmental Defense.
To prevent the worst anticipated problems of global warming, many scientists say the world will have to cut greenhouse gas emissions by 80 percent by mid-century, he said.
Other environmentalists remain vehemently opposed to new nuclear power plants.
"We reject the false choice between nukes and dirty coal," said Sarah Lynn Cunningham, a steering committee member of the Louisville Climate Action Network. "The cheapest, cleanest and most available energy source is energy efficiency. Who do we think we are to impose the risks and expense of radioactive waste on future generations because we're too lazy to use electricity more efficiently?"
Caylor said that the coal industry won't oppose the two bills and that the nation needs both coal-fired and nuclear power plants.The nuclear power industry supplies the nation with about 20 percent of its electricity; several plants came online in the 1990s.
Interest in new nuclear plantsNo licenses for a new nuclear plant have been secured since the late 1970s, but several companies filed for new licenses last year, and others plan to do so in the next few years, said Mitch Singer, a spokesman for the Nuclear Energy Institute.
The federal government has streamlined its licensing process and is moving toward standardized designs of nuclear reactors that should make them easier to build, operate and inspect, he said.
The nation's demand for electricity will increase 30 percent by 2030, he said, adding that the industry has proved it can safely manage the waste on-site while long-term options such as recycling and permanent storage are developed.
"We are going to need more coal, we are going to need more nuclear, we are going to need more renewables and we are going to need a healthy growth of conservation," Singer said.

Washington (Platts)--12Feb2008 UniStar officially told NRC that Nine Mile Point will be the site for a
potential new reactor in a combined construction permit-operating license, or
COL, application that the Constellation Energy-EDF Group joint venture plans
to submit in the fourth quarter of this year.
In the February 8 letter and a February 12 press release, UniStar Nuclear
Energy reaffirmed that the reactor, if built, would be a US Evolutionary Power
Reactor. The "reference" plant for that Areva design is Calvert Cliffs-3;
UniStar submitted part of the Calvert Cliffs COL application last year and
plans to turn in the rest next month, the press release said.
'Renewable'label wrong for nuclear
'Renewable'label wrong for nuclear
Last year, our state Senate approved a bill that would classify a host of energies -- solar, wind, geothermal, biogas, hydrogen -- as "renewable." But the bill was amended to also include nuclear power, which does not make sense because uranium fuel comes from a finite source just like oil and coal does.
The House this week voted 114-0 to remove nuclear energy from the list of renewable resources and returned the bill to its original intent.
The classification of nuclear as "renewable" is more than just senseless. It diverts attention from the original intent of the Energy Efficiency Act, which was to promote South Carolina's emerging, homegrown energy economy. Furthermore, allowing power companies to boost their "renewable" power ratings with nuclear-generated power creates loopholes for future energy production standards and discourages serious investments in real energy conservation.
South Carolina already has a significant investment in nuclear and more than 50 percent of the power produced here comes from nuclear plants. Last year's Base Load Review Act eliminates virtually all financial risks for utilities associated with building nuclear power plants in South Carolina.
It guarantees that utilities may collect from rate-payers all costs, plus a profit margin, incurred in studying the need for new nuclear power plants, as well as all costs incurred for actually constructing the multibillion-dollar nuclear plants. S360 need not be a referendum on nuclear energy because the General Assembly has already provided a major subsidy to utilities.
The sad irony is that South Carolina has vast potential for energy conservation. South Carolina is one of the least energy-efficient states in the country, consuming per capita more electricity than all but a few states and twice the amount of California. If efficiency is low hanging fruit elsewhere in the country, it is a freshly baked apple pie sitting on the kitchen countertop in South Carolina. Are we going to let it rot?
Despite the diversionary tactics of the big utilities, efficiency and renewable programs work. Vermont and California, for example, have tax rebate programs that have saved consumers millions and reduced power consumption dramatically. With newly passed net metering laws, North Carolina, Georgia and Virginia all have the jump on South Carolina. Indeed, North Carolina has a renewable portfolio standard requiring that its utilities obtain a modest percentage of their electricity from renewables.
State government can be the catalyst for attracting new investments in wind, solar and other renewables. It can create programs for financing and incentives for increasing efficiency.
But the good news is that the private sector will provide the delivery system and the jobs.
Most conservationists are like most South Carolinians: They are waiting for a comprehensive national energy plan that weighs the true costs, both environmental and economic, of different energy options. Our position is that efficiency and renewables are not only the cleanest and cheapest means of meeting immediate demand, they buy us the time we need to develop technologies that will make our country energy independent and secure.
Any rush for South Carolina to nuclear, or especially to coal, is premature because literally billions of dollars of energy are leaking out of our windows and through our ceilings and floors every day.
Instead of letting big power companies run roughshod over strategies to boost energy efficiency and promote renewables, legislators should focus on the real point of the Energy Efficiency Act -- creating ways to meet demand, and save money for consumers, by being more efficient.
Radioactive substances found in veggies

Radioactive levels three times higher than permitted have been found in vegetables grown in wetlands in the Wonderfontein spruit area between Randfontein and Potchefstroom, Beeld newspaper reported today. It cited what it described as "shocking revelations" yesterday in a report by the South African Nuclear Energy Corporation (Necsa) drawn up at the request of the National Nuclear Regulator some time back, but only released now. The newspaper said tests on asparagus, oats and onions produced in the Gerhard Minne wetlands showed that the level of radioactive substances was three times higher than the safe permissible level for human consumption. Pointing out that intensive gold mining takes place in the area - and that uranium as a by-product is found in mine dumps there - the news report said large tracts of land in the area of the Wonderfonteinspruit were 150 times more radioactive than the permitted level. It quoted an unidentified spokesman for the National Nuclear Regulator as saying yesterday that the test results in the report were worrying. Other vegetables grown in the area, such as cabbage, beetroot and spinach would now also be tested for traces of lead, cadmium, arsenic, zinc and cobalt. Higher than permitted radioactive substances in food get into humans’ bloodstream. It can lead to fatal kidney failure and various forms of cancer. The NNR spokesman was further indirectly quoted to the effect that tests may be carried out on people who ate the vegetables and that larger scale tests would be carried out on cattle and milk produced in the area. | ||
