As Saudi Arabia builds a civilian nuclear power program, its atomic energy authority has quietly given millions of dollars to a U.S. law firm to help aid its development.

The King Abdullah City for Atomic and Renewable Energy (K.A.CARE) already has paid Pillsbury Winthrop Shaw Pittman at least $2.8 million for a range of legal services, and given that the duration of the contract could well be “indefinite,” as one Pillsbury lawyer said, millions more could be heading the firm’s way. In its contract and related documents, Pillsbury outlines a seemingly unique legal effort, including the “ongoing training programs on many aspects of the law (including nuclear topics) under the auspices of ‘Pillsbury University.’ ”
