 power path to reliable decarbonization distribution even across the core Extended Fuel Cycle Enhanced Reactor Behavior Better ﬂux control means reduced Less aggressive reactor operation localized burnup, enabling longer reduces wear and tear on the system, fuel cycles and fewer outages for allows ﬁner control, and reduces the refueling risk of additional maintenance P. 12/22 PATENT PENDING CORE MODEL

CONFIDENTIAL DECADES OF LICENSING HISTORY LWRs have been in commercial operation for ~70 years, providing a robust foundation of operating data and licensing framework THE ONLY NRC APPROVED REACTOR TYPE LWRs represent 100% of operating reactors in the United States due to their proven technology & established regulatory familiarity 24/7 UNINTERRUPTED POWER Having a constant power supply is indispensable for data centers, where even a brief outage can lead to costly downtime IDEAL FOR INDUSTRIAL APPLICATIONS Our MMR’s 35 MW of thermal power is perfectly suited for a range of industrial applications requiring both process heat and electricity 10 YEAR LEU+ FUELING CYCLE The 10-year low enriched uranium fueling cycle drastically reduces op- erational costs by eliminating the need for frequent refueling P. 13/22 LIGHTWATER DESIGN BENEFITS
