| Research Abstract |
In order to develop a subcriticality monitor, which is necessary for safety operation of Accelerator-Driven Subcritical System (ADS), a real-time, continuous measuring system for alpha-value was developed based on Rossi-alpha method. Moreover, a new Rossi-alpha formula was derived based on detector-importance function theory. According to this new formula, a device for data-processing procedure accumulating correlation neutrons effectively is necessary to apply the measuring system proposed to ADS's that operate with low neutron multiplication and high reactor power.
