Abstract

Abstract

The heat pipe-cooled reactor (HPR) has a high temperature solid core, so during the startup, it will experience large temperature rise and thermal expansion. Besides, the state of working fluid in the heat pipe will change, which would bring complex reactivity feedback. In order to study the startup characteristics of HPR under feedback mechanism, taking the megawatt HPR MegaPower designed by Los Alamos National Laboratory (LANL) as the research object, using the HPR transient analysis code HPRTRAN, the startup conditions of MegaPower are calculated with three startup modes, and the startup characteristics of each mode are studied. The results show that, relatively large power fluctuation occurs during the startup process of HPR, there may be a "temperature platform" that is not conducive to the startup, and that rotating control drum at intervals is a safer and more practical startup scheme than rotating control drum continuously.
