The Topaz II Flight Safety team requires that the hardware for the Rusian-built reactor be modified to ensure that the reactor remains subcritical in the event of an inadvertent accident in which the reactor is submersed in wet sand or water. In April 1993, the American Flight safety team chose the fuel-out anticriticality device as the baseline for the hardware design. We describe the initial stages of the hardware design; show how the mechanism works; and describe its function, the functional and operational requirements, and the difficult design problems encountered. Also described, are the initial interactions between the Russian and American design teams. Because the effort is to add an American modification to a Russian flight reactor, this project has required unusual technical cooperation and consultation with the Russian design team.
