    Analysis: Nuclear power gaining popularity

    WASHINGTON, Aug. 25 (UPI) -- Nuclear power has become increasingly
    popular worldwide, particularly in the developing world, as a source
    of energy consumption, yet accidents involving radiation leaks
    continue in some of the world's safest nuclear plants. Amid rising
    oil prices, developing countries have little alternative but to
    depend on nuclear power.

    Developing countries are increasing their nuclear power usage.
    Armenia has one working reactor; Bulgaria has two; Ukraine three, and
    Romania one. One nuclear power plant is under construction in Iran
    and three more are planned. A total of 27 nuclear power plants are
    under construction in developing countries.

    Within the next several decades, energy consumption will at least
    double or triple in developing countries with growing populations and
    economies, according to Turkey's Hurriyet.

    Building nuclear power plants is expensive, but their operational
    costs are relatively low. It is not difficult to obtain nuclear fuels
    such as uranium or thorium. Nuclear power plants also produce
    virtually no carbon emissions.

    These power plants currently generate 16 percent of the electricity
    the world consumes, and currently account for 78 percent of
    electricity generation in France, about half of Belgium and Sweden's
    electricity, 28 percent of Germany's electricity, 20 percent in the
    United States, and 17 percent in Russia.

    But even as nuclear power becomes increasingly popular worldwide,
    some developed countries are considering shutting down their plants
    amid plant malfunctions. Belgium, the Netherlands, Germany, and
    Sweden have decided to gradually phase out their nuclear power
    plants.

    The oldest operating powerplant in Spain, the Jose Cabrera power
    station in Almonacid de Zorita, will be shut down on April 30, 2006.
    In 1994, more than 170 cracks were detected in the cover of the
    reactor vessel; the cracks were only repaired in 1997. Dismantling
    the station is expected to start in 2008 and completed in 2014 at a
    projected cost of $165 million, according to Spain's National
    Radioactive Waste Company.

    Sweden's Nuclear Power Inspectorate intends to impose stricter safety
    measures on the country's nuclear power plants, which generate about
    half of the country's electricity, to bring the country into line
    with IAEA and UN standards, according to the Svenska Dagbladet.
    Renovation work will total $809 million. Citizens voted in 1980 to
    phase out nuclear power by 2010, but the deadline was scrapped in
    1997 because the country had not worked out how to replace lost
    generating capacity.

    Nuclear power plants have seen massive leaks throughout the decades
    in some of the world's safest plants as well as the world's worst,
    and increased safety measures by the IAEA and the UN nuclear watch
    dog have not helped prevent such leaks. The third-safest power plant
    in Russia, the Volgodonsk facility in the Rostov region, had to be
    stopped twice within the past nine months due to emergencies in
    November 2003 and January 2004.

    Even Japan's Mihama plutonium-thermal plant, considered the world's
    safest power plant, saw four workers killed when steam leaked from a
    turbine reactor on August 9.

    Japan's Asahi Shimbun reported the accident as the worst ever in
    Japan's nuclear powerplants: "Trust was lost and the accident will
    have a great impact on future nuclear power development." And as
    nuclear powerplants get older and older, problems like pipe corrosion
    and equipment malfunction may increase.

    Following the Mihama accident, Greenpeace Russia has expressed
    concerns over conditions at Russian nuclear plants. "Japan's nuclear
    power plants are among the best in the world," Greenpeace said in a
    press release on Aug. 10. But in 2003, Japan failed to disclose the
    critical state of several of its reactors, which led to an immediate
    halt in operations at several nuclear plants.

    Greenpeace reported that major disasters in Russia's nuclear plants
    were similar to the accident in Japan. "There will be accidents as
    long as the nuclear power industry exists, and there could be a new
    Chernobyl at any moment," Russian Greenpeace head Ivan Blokov told
    Interfax on Aug. 8.

    Russia has a history of accidents. Three people were killed in an
    accident at the Leningrad nuclear powerplant on February 6, 1974. The
    facility was the venue for another disaster in autumn 1975, which
    involved a radiation leak that continued for more than a month.
    Fourteen people were killed in an accident at the Balakovo nuclear
    plant on June 27, 1985.

    A radiation leak also happened on U.S. soil when the 1979 Three Mile
    Island reactor leaked radioactive material.

    Despite such malfunctions, developing countries continue to construct
    nuclear plants. A newly-built reactor in Ukraine, launched at the
    Khmelnytskyy nuclear power plant, went offline due to massive
    overheating on August 13. Ukraine has had several radiation leaks
    throughout the decade, according to Washington-based Nuclear Threat
    Initiative reports.

    Equipment problems have also developed in two China-based power
    plants which Russia helped China build. Russian Federal Atomic Energy
    Agency Head Alexander Rumyantsev said that glitches arose in one
    reactor's equipment but hopes to eliminate those glitches within the
    next two months. Regarding another reactor close to Beijing,
    Rumyantsev told Interfax on Aug. 12, "Some parts of the equipment,
    however, have started to malfunction, but we know how to fix them."

    Slovenia's only nuclear power plant shut down automatically on August
    10 as a safety precaution after a mistake occurred in the system that
    regulates the amount of nuclear reaction taking place in the reactor.
    According to a statement from the Nuclear Power Plant Krsko, the
    control rods that regulate the amount of fission lost power after
    their power source broke down on the evening of Aug. 9.

    Another issue to consider is that nuclear technology can be used to
    make weapons as well as electricity. China and Pakistan signed a
    contract to supply a reactor pressure vessel for the second phase of
    the Chashma Nuclear Power Station in Pakistan. China Nuclear Energy
    Industry Corporation Deputy General Manager Huang Guojun said
    Pakistan had pledged that technology would be used solely for
    peaceful purposes with no transferal to a third parties. It is
    difficult to ignore the fact that nuclear technology has benefits in
    addition to its primary function of electricity generation.

    With no oil or gas of its own, Turkey has been debating the issue of
    construction of nuclear power plants in the country. But even if
    Turkey decides not to construct nuclear plants of its own, the
    country will be affected by any accidents that may occur in nearby
    countries -- just as in the case of the 1986 Chernobyl accident.

    Earthquake-prone countries such as Armenia may see disastrous
    radiation leaks to one of its units if an earthquake occurs. One of
    Armenia's power plant units has been shut down for repairs and
    nuclear fuel loading in late July, according to plant General
    Director Garik Markosian.

    Proper disposal of nuclear waste, meanwhile, is a growing problem in
    developing and developed countries. In short, nuclear power plants
    may be environmentally friendly and cheaper to operate generating a
    cheaper source of energy consumption -- but with the risks the plants
    pose, no one wants to live near one.

    "Until about 2 billion years ago, it was impossible to have any life
    on Earth. That is, there was so much radiation on Earth you couldn't
    have any life -- fish or anything. Gradually, about 2 billion years
    ago, the amount of radiation on this planet reduced and made it
    possible for some form of life to begin. It started in the seas, I
    understand from what I've read. And that amount of radiation has been
    gradually decreasing because all radiation has a half-life, which
    means ultimately there will be no radiation. Now, when we go back to
    using nuclear power, we are creating something that nature tried to
    destroy to make life possible," said Admiral Hyman Rickover, known as
    the father of the U.S. nuclear navy.
