VLADIVOSTOK, Russia (Reuters) - A fire burned for
five hours on an atomic-powered submarine
undergoing repairs near Russia's eastern port of
Vladivostok on Monday, but naval and shipyard
officials said there was no risk of a radiation leak
and nobody was hurt.
Black smoke poured from the submarine Tomsk,
which is powered by two nuclear reactors, after it
caught fire at the Zvezda shipyard in Bolshoi
Kamen, about 25 km (15 miles) across a bay from
Vladivostok on the Sea of Japan, authorities said.
The fire was the second on board a Russian
nuclear-powered submarine in less than two years.
"There is no threat of radioactive contamination,"
the state-run Itar-Tass news agency cited an
unidentified official in Russia's Pacific Fleet
command as saying. Regional emergency officials
said radiation levels in the area were within the
normal range.
After the fire was extinguished, firefighters
continued to douse the area to ensure it did not flare
up again, the state-owned United Shipbuilding
Corporation, which operates the shipyard, said in a
statement.
It said there were no casualties and both reactors
had been shut off and were in "safe condition". The
firm also said there had been no weapons aboard
the ship, which normally carries up to 24 guided
missiles, when the fire broke out.
When a blaze engulfed the atomic-powered
Yekaterinburg at a shipyard in northwestern Russia
in December 2011, official statements said there
had been no nuclear missiles on board the sub, but
a respected magazine later cited several unnamed
sources as saying this was untrue.
Navy sources said on Monday that, in addition to
two firefighting vessels, a ship that monitors
radiation levels had been sent to the area, Russian
news agencies reported.
The fire started in a ballast area of the submarine
during welding works after an acetylene torch was
used to cut through a grate, setting a rubber seal,
cables and paint on fire, RIA cited an unnamed
official at the shipyard as saying.
The official said the cistern was outside the sealed
core of the submarine where the reactors are
located, according to RIA.
Russia's navy has suffered several fatal accidents
since the collapse of the Soviet Union in 1991.
The nuclear-powered submarine Kursk sank in the
Barents Sea in 2000, killing all 118 crewmen
aboard, and 20 people died aboard the submarine
Nerpa in 2008 when its fire extinguishing system
went off, flooding compartments with deadly gas.
