Through the multimodular scheme, the inherent safety of the MHTGR is applicable to the large-scale plants with any desired power ratings.
The control laws for the nuclear power, primary helium flowrate, feedwater flowrate, MHTGR outlet helium temperature, OTSG outlet steam temperature, and main steam pressure, which have the feedback regulation function, are all given in this subsection.
The module control laws include the feedback regulation algorithms of the nuclear power, primary helium flowrate, feedwater flowrate, MHTGR outlet helium temperature, and OTSG outlet steam temperature, which are designed based on the physics-based NSSS control method proposed in [30-36].
Due to its inherent safety feature and potential economic competitiveness, the modular high temperature gas-cooled reactor (MHTGR) has already been seen as one of the best candidates in building the next generation nuclear plants.
