This case removes primary cooling circuits and pumps, using external fins and passive heat dissipation to improve reactor safety.
This case uses gravity-driven coolant risers and one-way diodes to maintain coast-down cooling without backup power.
A nuclear reactor design integrates phase-change material to absorb decay heat via latent heat storage within a secondary vessel.
Liquid Zamak alloys with residual sodium on spent fuel assemblies to eliminate oxide gaps and enable safe dry storage without liquid cooling.
