Nuke Agency: Increase of Power Plants in Works

 

Jun 28 - Scripps Howard

Fifty years after the world's first nuclear-power electric-generating station went on the grid near Moscow, experts at the International Atomic Energy Agency say it's likely many more nuclear-power plants are coming _ but it's unclear how many will be built in the United States or Western Europe.

Twenty-two of the last 31 nuclear-power plants tied to the energy grid have been built in Asia, as are 18 of the 27 plants now under construction. Another eight new plants are being built in Eastern Europe.

"The more we look to the future, the more we can expect countries to be considering the potential benefits that expanding nuclear power has to offer for the global environment and for economic growth," said agency Director General Mohamed ElBaradei, as he joined an international conference of nuclear-power experts meeting to discuss the future of the industry over the next 50 years.

Population growth, power demand and shortages of other fuels have driven nuclear-plant construction in countries like Japan, South Korea and India. But concerns about safety and waste disposal have dampened enthusiasm for nuclear electricity generation in the United States, Canada and Western Europe since the accidents at Three Mile Island in Pennsylvania (1979) and Chernobyl in what is now Ukraine (1986).

The IAEA notes that four Western European nations _ Germany, Belgium, the Netherlands and Sweden _ have phase-out policies for nuclear power.

However, with oil and natural-gas prices soaring and emissions-control requirements tightening, other countries are discovering new value from nuclear power. Finland is slated to start work on a new plant next year, and France is considering replacing retiring reactors.

Agency officials note that several developing countries that don't currently operate nuclear plants have recently approached them about the possibility of bringing reactors online.

Many of the Chernobyl-type reactors have been or soon will be retired, and the rest have added safety features. The IAEA has worked with all nuclear nations on safeguards and to develop improved reactor designs, including new units that could better utilize reprocessed fuel rods.

"The decision to adopt nuclear power cannot be made on a 'one size fits all' basis," ElBaradei said. "New nuclear plants are most attractive where energy demand is growing and alternative resources are scarce, and where energy security and reduced air pollution and greenhouse gases are a priority."

In the United States, 75 percent of the 104 reactors in operation either have been approved for another 20 years of service by the Nuclear Regulatory Commission or are in the process of doing so _ a reversal from the 1980s and 1990s, when plants were shut down or running at reduced capacity more often than not.

The Department of Energy has set up a new program to aid private firms in getting combined licenses to build and operate new plants, and three consortia of energy companies, nuclear suppliers and engineering firms have started the application process, although many political, legal and economic hurdles remain.

Worldwide, the IAEA's most optimistic short-term projection is that nuclear power will generate 70 percent more electricity in 2030 than it does now. Atomic energy has made up about 16 percent of the world's juice since 1987.

But other analysis done in the context of changing energy sources to help forestall carbon emissions and global warming suggests that nuclear-power production could increase to about 27 percent of electricity production.

The long-term problem of what to do with spent fuel that will remain highly radioactive for tens of thousands of years remains. Only a few countries, including the United States and Finland, have moved toward establishing repositories, and the IAEA is increasing efforts to come up with long-term storage sites under international control.
