(c) Sections (b)(7) is revised to read: "(7) PUBLIC LANDS.—No individual, corporation, partnership, or association, which had any part, directly or indirectly, in the development of the atomic energy program, may benefit by any location, entry, or settlement upon the public domain made after such individual, corporation, partnership, or association took part in such program, if such individual, corporation, partnership, or association, by reason of having had such part in the development of the atomic energy program, acquired confidential official information as to the existence of deposits of such uranium, thorium, or other fissionable source materials in the specific lands upon which such location, entry, or settlement is made, and subsequent to the date of the enactment of this Act made such location, entry, or settlement or cause the same to be made for his, or its, or their benefit. I n cases where any patent, conveyance, lease, permit, or other authorization has been issued, which reserved to the United States fissionable source materials and the right to enter upon the land and prospect for, mine, and remove the same, the head of the department or agency which issued the patent, conveyance, lease, permit, or other authorization shall, on application of the holder thereof, issue a new or supplemental patent, conveyance, lease, permit, or other authorization without such reservation."
