 note = {The 200 kWe uranium-nitride fueled lithium cooled fast reactor concept RAPID-L (Refueling by All Pins Integrated Design-L) to be combined with thermoelectric power conversion system for lunar base power system is demonstrated. Unique challenges in reactivity control systems design have been attempted in RAPID-L concept. The reactor involves the following innovative reactivity control systems: Lithium Expansion Modules (LEM) for inherent reactivity feedback, Lithium Injection Modules (LIM) for inherent ultimate shutdown, and Lithium Release Modules (LRM) for automated reactor startup. All these systems adopt lithium-6 as a liquid poison instead of conventional B4C rods or Be reflectors. These systems are effective independent of the magnitude and direction of the gravity force. In 2006, however, the following design amendment has been made. (1) B4C poison rods were added to ensure criticality safety in unintended positive reactivity insertion by LRMs due to fire in the launch phase accident; because LRM freeze seal melts at 800 C which result in positive reactivity insertion. (2) Lower hot standby temperature of 200 C was adopted instead of conventional 800 C to reduce the external power at the startup. In this paper, RAPID-L reactor control systems, startup sequence and its transient characteristics are presented., 資料番号: AA0063965028},
