Tuesday, February 13, 1996 MINSK, Belarus (Reuter) - Belarus, the country worst hit by the Chernobyl nuclear disaster, Tuesday put a $235 billion price tag on dealing with its aftermath and Ukraine demanded faster action from the West to close the stricken power plant. Belarus's Chernobyl minister said foreign aid since the 1986 catastrophe provided a tiny fraction of what was needed to clean up huge stretches of contaminated forests, resettle thousands of people and tackle health problems. "International cooperation started here only in 1990 and although we have obtained large sums of money it is not enough," Ivan Kenik told a news conference devoted to government plans ahead of the 10th anniversary of the world's worst nuclear accident. "The new estimate for the total damages from the Chernobyl catastrophe from 1986 to 2015 is put at $235 billion -- that's 21 times the size of our 1991 national budget. And this is by no means a final estimate." But Kenik dismissed as pointless plans by some legislators to sue Russia -- as the legal successor of the Soviet Union -- for damage caused by the fire and explosion at the Chernobyl power plant just over the border in Ukraine. In Kiev, Environment Minister Yuri Kostenko said Ukraine would be unable to close the station by the year 2000 unless the West simplified procedures for extending financial aid. Western attention, he said, had faded since Ukraine and the Group of Seven rich countries signed a memorandum in December envisaging $2.3 billion in loans and grants to shut down two reactors still functioning at the station. The document sets the year 2000 as an optimal goal but is not binding. "We've signed the memorandum, but the existing procedures for issuing credits and grants are so complex that if we comply with them . . . we will be unable to close Chernobyl by the year 2000," said Kostenko, Kiev's top negotiator on Chernobyl. Ukrainian President Leonid Kuchma intended to lobby Western leaders to speed up the process at an April G7 summit on nuclear safety to be held in Moscow on the eve of the anniversary, he said. Kuchma also plans to raise the issue with President Clinton during talks in Washington next week. "We need conclusively to dot the i's and cross the t's on Chernobyl," a spokesman quoted Kuchma as telling U.S. Ambassador William Miller. The Chernobyl disaster on April 26, 1986, sent a cloud of radiation over much of Europe and thousands of people have since died. Kuchma agreed to close the station under heavy pressure from the West, which considers the facility unsafe. But Ukraine and Belarus, struggling to keep their post-Soviet economies above water, have complained that help from the international community is inadequate. Ukraine estimates the cost of closing Chernobyl at about $4 billion -- including finding sources of energy to make up for the power generated by the plant and replacing the crumbling "tomb" covering the station's ruined fourth reactor. Both countries say they spend up to 10 percent of their annual budgets on dealing with the accident's consequences.
