MMS 코드를 이용한 소듐냉각고속로의 출력변동운전 모의

The MMS model for KALIMER-600 plant dynamics analysis are developed. The models include NSSS, BOP, BOP controls, and the supervisory plant controls. The NSSS model is subdivided into component models, such as a CORE, IHXs, Pumps, SGs, and the rest of the NSSS loop model. The BOP model is subdivided into a steam subsystem, feedwater subsystem, and preheater subsystem. All these models have been incorporated into the Master model to simulate transients in the plant. Representative results for power ramp change from 100% to 25% with a demanded load reduction of 25% at 5% per minute in 2000 sec demonstrate the suitability of this model for study of power maneuvering without severe oscillation.
