New Mexico District Court in Santa Fe has awarded United Nuclear Corp. its total claim for monetary damages of $8.26 million in a case against General Atomic Co., a partnership of Gulf Oil Corp. and the Royal Dutch/Shell Group.

Against the damages, awarded late Tuesday and announced yesterday by Falls Church-based United Nuclear, the court allowed General Atomic an "offset" of $8.03 million for money advanced to United and other adjustments.

Most of the offset involved a $6 million advance payment by General Atomic to the Northern Virginia firm.

On April 4, New Mexico Judge Edwin Felter held that contracts calling for the delivery of some 27 million pounds of uranium by United to General Atomic were void.

The decision on monetary damages ends trial proceedings in the case, although various appeals have been filed in New Mexico courts and the U.S. Supreme Court.

On Monday, the Supreme Court declined to consider two petitions filed by General Atomic, seeking review of New Mexico court decisions. The Supreme Court still has before it a General Atomic appeal, seeking a directive from the U.S. court to the state trial court to permit arbitration to the controversy.
