Mushroom cloud from the Cold War era Totsk nuclear bomb test in the Soviet Union.

Totsk nuclear exercise (codename “Snowball”) undertaken by the Soviet Army in Orenburg, Soviet Union during the Cold War. An immense mushroom cloud forms after a 40-kiloton (170 TJ) RDS-4 atomic bomb detonates 1,150 ft. (350 meters) above the Totskoye range.

Engineers and scientists working on development work during the construction of the Sodium Reactor Experiment

Atomics International engineers working on test and development work on reactor components during the construction of the Sodium Reactor Experiment nuclear power plant at the Santa Susana Field Laboratory in California, United States. A scientist studies the weight of a metal tube. Scientists study mockup fuel elements irradiated in the thermal column of a research reactor. A hydraulic loop was used to simulate sodium flow conditions on top of a tower. Scientist inserts a hydraulic loop. Sodium flowing as seen from the hydraulic loop experiment. Full scale mockup of the fuel handling system was checked mechanically. A prototype coolant pump being studied using a temperature sodium loop. A scientist pushes some buttons of a machine. Machine gauge measures temperature in Fahrenheit. A scientist in protective suit turns a wheel. Scientists lower heavy tube.

Construction of the Sodium Reactor Experiment nuclear power plant in Southern California

The Santa Susana Mountains in Southern California. Bulldozers clear trees in the Santa Susana Mountains. Explosives blasting cleared land to build the foundation of the planned Sodium Reactor Experiment nuclear power plant at the Santa Susana Field Laboratory. Construction workers build the core cavity liner of the Sodium Reactor Experiment nuclear power plant. The core cavity liner of the sodium reactor before concrete is poured to make the foundation. A man welds steel pipes in the outer surface of the core cavity. A large circular hole for the inlet and outlet piping. Workers set up basic structures after the core cavity liner and foundation are built. Some workers are digging near concrete columns. A worker pushes a wheelbarrow. Concrete poured into wheelbarrow. The wheelbarrow pours concrete into a backhoe. Workers pour wet concrete into the foundation. Animation depicts four concentric rings installed at the bottom of the cavity liner. A ladder inside a tank. Workers install blocks of thermal insulation materials. A crane carries the outer tank made from low-alloy steel. Workers carefully lower the outer tank into the core cavity. Stacked thermal shield rings at the construction site. The “Pacific” crane lowers a thermal shield ring into place. The crane brings the stainless-steel core tank. The crane lowers the core tank into the core cavity. Stainless steel bellows is put into place to seal the core tank and outer tank. Animation shows how bellows maintain the sodium vapors within the core area. Workers in white protective uniforms install the moderator and reflector units under conditions of extreme cleanliness. A worker uses a high-capacity vacuum cleaner to clean parts. The workers proceed to install the 75-ton top shield. Scientists monitor the pumps that monitor the rate of coolant flow in the sodium loops. A scientist inspects the fuel elements installed in the core. Scientists working at a control room of the Sodium Reactor Experiment nuclear power plant. They monitor the reactor stability. Timer connected to the control rod. Various meters measuring various powers such as electrical, thermal, and main primary sodium flow, steam flow rate. A Honeywell meter measuring the reactor inlet temperature. A sodium inlet temperature meter. A scientist measures shielding effectiveness during power runs. The scientist inspects shield blocks above the radioactive coolant galleries and over the reactor core.
