Earthquake-proof |
STRONG. Simple
low-pressure reactor-vessel
Reactor stop by the loss of fuel, which is
chemical inert, and frozen as stable-glass.
Fission-gases removed. |

WEAK dangerous.
High-pressure reactor-vessel
Core-melt by coolant-loss. Fission-gases (Kr.
Xe) release by failure |

Spent-Fuel |
EASY. Dry
processing: fluorination, electrolysis,
extraction by molten salt or liquid metal. No
fuel-rod fabri. |
◎ |
DIFFICULT &
Expensive. Very complex plant, and
Anxiety of re-criticality. Re-fabrication of
fuel-rods & assembly. |
