SUMMARY
Navy nuclear reactors utilize lithium hydroxide and pure water pressurized to over 2200 PSI as coolant. Lithium hydroxide is specifically included to optimize pH levels, thereby minimizing corrosion within the core and primary cooling circuit components. At an absolute pressure of 2200 psia (15.16 MPa), the saturation temperature of the coolant is approximately 647°F (341.7°C), indicating the threshold for the onset of nucleate boiling when fuel cladding temperatures approach this level.
