The safety systems are passive, Here is the comparison, Did not copy well so basically the good is SMR, and the bad is current systems, so my opinion is that fossil, wind, solar are against this, It is actually the best system. If scaled up the parts can be massed produced. Current‐generation safety‐related systems SMR safety systems
High‐pressure injection system.
Low‐pressure injection system. No active safety injection system required. Core cooling is maintained using passive systems.
Emergency sump and associated net positive suction head (NPSH) requirements for safety‐related pumps. No safety‐related pumps for accident mitigation; therefore, no need for sumps and protection of their suction supply.
Emergency diesel generators. Passive design does not require emergency alternating‐current (AC) power to maintain core cooling. Core heat removed by heat transfer through vessel.
Active containment heat systems. None required because of passive heat rejection out of containment.
Containment spray system. Spray systems are not required to reduce steam pressure or to remove radioiodine from containment.
Emergency core cooling system (ECCS) initiation, instrumentation and control (I&C) systems. Complex systems require significant amount of online testing that contributes to plant unreliability and challenges of safety systems with inadvertent initiations. Simpler and/or passive safety systems require less testing and are not as prone to inadvertent initiation.
Emergency feedwater system, condensate storage tanks, and associated emergency cooling water supplies. Ability to remove core heat without an emergency feedwater system is a significant safety enhancement.
