6 FAQs about [National Nuclear Energy Storage Liquid Flow]

Is a nuclear integrated liquid air energy storage system possible?

A common result of these studies is that the direct integration between the nuclear steam cycle and energy storage system can make the entire system flexible and economic while the nuclear core power is maintained. Based on these previous works, the authors propose a nuclear integrated Liquid Air Energy Storage System (LAES).

What is energy storage system in nuclear power plant?

One of the highlighted technologies is the integration of energy storage system to nuclear power plant. Energy Storage Systems are generally used for grid stabilization, arbitrage, energy security, and frequency control .

Why is a nuclear power plant integrated with LAEs?

When nuclear power plant is integrated with LAES, the capacity factor increases by 3%p which allows more flexible operation and provides better economy despite of its LAES round efficiency disadvantage. Fig. 15 shows the comparison of cycle performance with various energy storage systems.

What is LAEs mechanically integrated with nuclear steam cycle?

Based on these considerations, in this research, the new concept of LAES mechanically integrated with nuclear steam cycle is suggested. Mechanical integration means that the mechanical energy of steam (i.e. thermodynamic work) is used while thermal integration is using thermal energy of steam (i.e. heat transfer).

What is the LCOE of nuclear integrated LAEs?

In the light of integration, the LCOE of nuclear integrated LAES shows the lowest vale in U.S as $127/MWh and the highest value in Japan as $182.8/MWh. Thus, by integrating nuclear power to LAES, the LCOE is greatly reduced due to the advantages of low power generation cost of nuclear power plant.

What happens if power requirement exceeds nominal reactor electrical output?

When the power requirement is lower than the nominal reactor electrical output, the system will operate in charging mode and direct thermal energy into the TES. When the power requirement exceeds the nominal reactor electrical output, the system will operate in discharging mode and meet the power requirement by dispatching energy from the TES.
