- COVER STORIES, Page 44THE NEW RUSSIA: ENVIRONMENTNuclear Time Bombs

- Not only is Chernobyl still a danger. So are many similar
- reactors, sunken submarines and radioactive waste dumps.

-
- Few environmental nightmares strike a more frightening
- chord than Chernobyl. It is not merely the radioactive mess left
- by the 1986 meltdown. Six years later, 19 similar
- graphite-moderated nuclear time bombs are still ticking away,
- alarming relics of a badly designed, haplessly run nuclear-power
- program that none of the independent republics of the former
- Soviet Union can afford to shut down. The potential killers
- bring light, heat and power to parts of Russia, Ukraine and
- Lithuania, where their immediate decommissioning would create
- unacceptable economic disruption and even civil unrest.
-
- The handling of Chernobyl is hardly reassuring. When
- workers finished the huge steel-and-concrete shell that entombs
- the intensely radioactive mass of the shattered No. 4 reactor
- in late 1986, Soviet officials declared the site safe for at
- least 30 years. Yet today the sarcophagus is cracked, crumbling
- and in peril of a disastrous collapse. The melted-down fuel is
- turning to unstable dust. Contaminated objects are being
- smuggled out of the poorly guarded 1,092-sq.-mi. exclusion zone.
- Birds fly into the sarcophagus through holes as big as a garage
- door; rats breed in the ruin. The structure is so unsteady that
- a strong windstorm could smash it, sending a plume of
- radioactive dust into the atmosphere. "Nothing is being done to
- clean it up," says Alex Sich, an American engineer who has
- studied the Chernobyl site.
-
- Nor has anything been done about the threat of nuclear
- contamination in the oceans. Over the years four Soviet
- submarines, their reactors full of nuclear fuel, sank
- accidentally. The most dangerous, the world was reminded last
- week, may be the Komsomolets, which caught fire in April 1989
- and went down in more than 4,500 ft. of water 310 miles off the
- coast of Norway. The wreck is already leaking cesium-137, a
- carcinogenic isotope. So far the leakage is considered too small
- to affect marine life or human health.
-
- But the Komsomolets also carried two nuclear torpedoes
- containing 28 lbs. of plutonium with a half-life of 24,000 years
- and toxicity so high that a speck can kill. Russian experts
- warned that the plutonium could spill into the water and
- contaminate vast reaches of ocean as early as 1994.
-
- At Chernobyl the concern is even more immediate. There is
- ever-present danger in the operation of reactor No. 3 too.
- Despite a government plan to shut down the entire plant, No. 3
- was reactivated after officials pleaded that its energy was
- essential for the coming winter. Like its ruined twin, No. 3 is
- considered fundamentally unsafe by the International Atomic
- Energy Agency. It may be even more so now: many Russian
- operators have returned home, leaving a reactor run by
- Ukrainians who are ill-trained, badly paid and demoralized.
-
- Little progress has been made on cleaning up the
- surrounding region. There is no equipment to decontaminate
- topsoil, and contaminated groundwater is backing up behind a
- concrete barrier near the reservoir that supplies water to the
- 2.6 million residents of Kiev. More than 700 peasants evacuated
- in 1986 have quietly moved back to their farm plots, where they
- consume contaminated animals and produce. "They would rather die
- here than live somewhere else," says Alexander Borovoi, a
- Russian nuclear physicist in charge of the sarcophagus. Some
- returned to find their homes pillaged of religious art. Although
- contaminated with cesium 137 and strontium 90, some of the icons
- have probably entered the world art market.
-
- Hot spots abound in the buildings and equipment around
- Chernobyl. A disabled bulldozer sets off alarms on hand-held
- radiometers, showing 10 times the internationally accepted
- exposure level for nuclear-power workers. The big Mi-8
- helicopters that were used to drop sand into the blazing reactor
- in 1986 -- collecting such heavy radiation that some pilots died
- -- rest in a field along with hundreds of contaminated trucks
- and armored personnel carriers, many stripped of engines and
- electronic gear. The radiation is not enough to cause immediate
- illness, but looters are taking long-term risks. Health
- officials estimate that 10,000 deaths will result from
- fallout-induced cancers.
-
- Chernobyl is only one of many examples of nuclear
- contamination and carelessness throughout the former Soviet
- Union. A devastating 1957 nuclear-waste explosion and subsequent
- dumping of contaminants near Chelyabinsk, 900 miles east of
- Moscow, is now thought to have released pollution totaling 1.2
- billion curies, a unit measure of contamination. That compares
- with about 3 million curies from the bomb that destroyed
- Hiroshima. Says Murray Feshbach, co-author of Ecocide in the
- USSR: "The new evidence of widespread nuclear pollution is so
- incredible, it's hard to believe."
-
- For more than 30 years the Soviets intentionally dumped
- enormous quantities of radioactive rubbish into the environment.
- Russian authorities have pinpointed a series of such sites along
- the country's Arctic coast, where currents can carry
- contaminants to Alaska and the north coast of Canada.
-
- The worst of the poisoned sites is Novaya Zemlya, two
- Arctic islands used as a nuclear-weapons test range. Already
- contaminated by bomb fallout, the islands were turned into a
- nuclear garbage bin. The Russians admit they dropped as many as
- 17,000 barrels of radioactive waste into the surrounding seas
- since 1964. Sailors reportedly shot holes in some of the barrels
- when they failed to sink.
-
- At least eight marine reactors, three from the nuclear
- icebreaker Lenin and the others from decommissioned submarines,
- have been scuttled in Novaya Zemlya's shallow bays. The dead
- reactors are encased in layers of steel and may be harmless for
- many years. But inside, their cores contain dangerous isotopes.
-
- The West has been highly critical of the Soviet nuclear
- legacy but has done little to alleviate the danger. Foreigners
- come mainly to gather data on the effects -- medical,
- industrial and political -- of accidents, and then disappear.
- "Sometimes we feel like rabbits in a laboratory," says Viktor
- Ribachuk, Ukraine's deputy environment minister. Ukraine
- officials argue that they cannot do without nuclear power for
- the next five or six years, and many contend they will need it
- permanently.
-
- So no one expects to see the end of these nuclear time
- bombs anytime soon. There are plans afoot to extend the life of
- some old reactors and to lift a post-Chernobyl moratorium on
- completing others. Dangerous reactors will be running into the
- 21st century. The crumbling sarcophagus over Chernobyl's
- devastated No. 4 may still be there too -- if it has not
- collapsed by then.
