The technical specifications of the 4S reactor are unique in the Nuclear Industry . The actual reactor would be located in sealed, cylindrical vault 30 m (98 ft) underground, while the building above ground would be 22 x 16 x 11 m (72 × 52.5 x 36 ft) in size. This power plant is designed to provide 10 Megawatt s of power. The 4S uses Neutron Reflector panels around the perimeter to maintain Neutron density. These reflector panels replace complicated control rods, yet keep the ability to Shut Down The Nuclear Reaction in case of an emergency. Additionally, the Toshiba 4S utilizes Liquid Sodium As A Coolant , allowing the reactor to operate 200 degrees hotter than if it used water. This means that the reactor is depressurized, as water at this temperature would run at thousands of pounds per square inch. The reactor is expected to provide electric energy for between 5 and 13 cents/kWh in Galena, Alaska, which factors in only operating costs. On paper, it has been determined that the reactor could run for 30 years without being refueled. The Toshiba 4S Nuclear Battery is being proposed as the power source for the Galena Nuclear Power Plant in Galena, Alaska. REFERENCES
