"METROPOLIS, Ill. — Honeywell says there's no evidence that a weekend leak of a compound used in uranium enrichment at its southern Illinois plant escaped the building.

Company spokesman Peter Dalpe says no injuries resulted from the leak of uranium hexafluoride Sunday night at Honeywell's site in Metropolis. The U.S. Nuclear Regulatory Commission has been notified, and Reuters reported Wednesday that an inspector from the NRC started an investigation Tuesday, according to NRC spokesman Roger Hannah.

"At this point we're still in a fact-finding mode," Mr. Hannah told Reuters. "We haven't come to any conclusions about whether processes weren't followed." He said the investigation could take a few days to a week. "
