Subjects discussed in this file include the effects of recent scientific controversies in the U.S.S.R.; a report of a conversation with a disaffected Soviet citizen in which he claimed that there was a large atomic energy facility in the Caucasus; a debate about the reliability of this report, which some felt was either fabricated or heavily embellished; and arrangements for sharing this report with the Americans.
