An award made to a claimant under this section shall be payable out of any moneys made available to the Commission. The acceptance by the claimant of the award shall be final and conclusive on the claimant, and shall constitute a complete release by the claimant of his claim against the United States and against any employee of the United States acting in the course of his employment who is involved in the matter giving rise to the claim.
Except as provided in section 3776 of this title, no action for damages on claims cognizable under this part shall lie against the United States or the Commission, and no such action shall lie against any officer or employee of the United States. Neither this section nor section 3776 of this title shall preclude actions against officers or employees of the United States for injuries resulting from their acts outside the scope of their employment or not in the line of their duties, or from their acts committed with the intent to injure the person or property of another.
The provisions of section 1346(b) of title 28 and the provisions of chapter 171 of such title shall not apply to claims cognizable under this part.
