The half-ton of uranium, enough to make as many as 50 bombs, has been stored at a nuclear fuel fabrication at Ust-Kamenogorsk in eastern Kazakhstan, The New York Times said in its Wednesday editions.

In recent weeks, the North cut U . N . seals and impeded surveillance equipment at a nuclear reactor in Yongbyon and its spent fuel pond, a fuel fabrication plant and a reprocessing facility.

In March 1999, the U . S . Department of Energy ( DOE ) reversed its policy and signed a contract with a consortium of Duke Energy, mixed oxide ( MOX ) fuel fabrication facility.

It was an early pioneer of LPG products and building upon its base of substantial uranium ore reserves, established a role in conversion and fuel fabrication and in recovery and reprocessing for the fledgling nuclear power industry.
45.
Eight years ago at another fuel fabrication plant operated by General Electric near Wilmington, N . C ., workers struggled for several days to keep uranium in a water-filled tank from setting off a nuclear chain reaction.
46.
After preliminary tests, experts said they believed that the high enrichment indicates that the uranium could have come from a either a storage site of the Russian Navy or a fuel fabrication plant in the former Soviet Union.
47.
The New York Times said in Wednesday's editions the half-ton of enriched uranium, which experts said would be enough to make 50 bombs, had been stored at a poorly protected nuclear fuel fabrication plant at Ust-Kamenogorsk in eastern Kazakhstan.

The National Academy of Sciences panel concluded that if a MOX fuel fabrication plant could be licensed and built, and if enough reactors were modified to use the fuel, then the process could probably begin in about 10 years.
49.
First, uranium ore is converted to hexafloride gas, then it is shipped to another plant for enrichment, and then to one of seven fuel fabrication plants that turn the gaseous or liquid uranium into powder and then reactor fuel pellets.
50.
Before uranium is ready for use as nuclear fuel in reactors, it must undergo a number of intermediary processing steps which are identified as the front end of the nuclear fuel cycle : fuel fabrication to produce fuel assemblies or bundles.
