>KIEV, Ukraine (AP) - Workers at the Chernobyl nuclear plant found a

>The 8-inch fragment, found last week, emits radiation of some 200

>Chernobyl's only working reactor, No.  3, said Svetlana Linkevych,
>a spokeswoman for sarcophagus workers.

>Experts are now determining how the fuel got onto the sarcophagus

>
>The sarcophagus was hastily constructed to cover the reactor that
>exploded and caught fire in April, 26, 1986, spewing a radioactive
>cloud over parts of Europe.

>With the help of foreign aid, Ukraine is trying to make the leaky
>structure environmentally safe.  It is believed to contain tons of

>Some 180 tons of nuclear fuel were located in the reactor at the

>Ukraine has promised to close down the plant on Dec.  15 following
>pressure from Western nations, domestic and foreign environmental
>groups and ordinary Ukrainians concerned about the site's safety.
