6 FAQs about [Nuclear power coupling and energy storage]

Can thermal energy storage be coupled to nuclear power sources?

Various methods of thermal energy storage (TES) can be coupled to nuclear (or renewable) power sources to help absorb grid variability caused by daily load demand changes and renewable intermittency.

Can thermal energy storage and nuclear energy be a transformative contribution?

Jan 2022, 1: 011006 (9 pages) Thermal energy storage (TES) coupled with nuclear energy could be a transformative contribution to address the mismatch in energy production and demand that occur with the expanding use of solar and wind energy. TES can generate new revenue for the nuclear plant and help decarbonize the electricity grid.

Does storage increase nuclear power plant capacity?

They estimated that storage would increase the capacity factor of a nuclear power plant by 2.5% with a renewable penetration of 60% and discharge power equal to 110% of the nominal baseload.

Can two-tank molten salts thermal energy storage be used for solar power plants?

Two-tank molten salt storage for parabolic trough solar power plants Energy, 29 ( 5–6) ( 2004), pp. 883 - 893, 10.1016/S0360-5442 (03)00193-2 Two-tank molten salts thermal energy storage system for solar power plants at pilot plant scale: Lessons learnt and recommendations for its design, start-up and operation

Can nuclear power be used as a heat source?

Integration with nuclear is limited to stored cold water employed by buildings for cooling applications using an electric chiller, or hot water that serves as a heat source by being drawn out of a low-pressure turbine. This low level of compatibility with high-quality steam leads to an FOM of 0 for the capability to discharge high quality heat.

Can a nuclear-generated heat exchanger discharge high-quality heat?

Any interface with steam produced by nuclear-generated heat would require new heat exchange methods. Thus far, experience does not indicate the possibility of high storage temperatures/pressures, so an FOM of 0 was assigned for compatibility to discharge high-quality heat.
