A unique process for deactivating residual sodium in Liquid Metal Fast Breeder Reactor systems which uses humidified carbon dioxide at ambient temperature and pressure to convert residual sodium into solid sodium bicarbonate. The first and second apparatuses are arranged above the engine. In another embodiment, a control system includes a stator plate configured to have a plurality of radially offset slots. When a user reaches a point of achievement, the system saves a new copy of game data over one of the previous copies. Driving the lenses by means of a cam member minimizes energy loss due to friction, and thus sufficiently improves drive efficiency. The system can be implemented in either a point-to-point modem environment or a multi-point environment, for example, but not limited to, MVL or DMT.
