Next-gen nuclear reactors use solar salts to tackle extreme heat like never before

SMRTR summary

Researchers at MIT and NANO Nuclear are investigating if "solar salts" used in solar thermal plants can withstand the extreme conditions inside advanced nuclear reactors. The $500,000 study will subject molten nitrate salts to gamma radiation, aiming to determine their viability for thermal energy storage and cooling in next-generation nuclear systems. Success could accelerate development of safer, more efficient reactors and impact other clean energy applications.
