Eliminating the hot water surrounding the plant, security of the Nuclear site is greater since infrared sighting is prevented with shielding just the reactor. Reactor byproducts can be separated and isolated to protect the environment and provide radioactive reagents for research. Liquid Nitrogen availability also provides the fixed fire and crises control for the entire facility eliminating water damage and electrical arcing keeping the computer and control system functional through crises situations.
