Next to the main building, work is ongoing for the concrete structure that will host the atmospheric cooling system. These "cooling towers" will dissipate the residual energy from the reactor. Last week, as work on the tallest part of the structure was completed, a small tree was placed on the roof and hung with garlands—a construction tradition that originates in Eastern Europe and is called "topping out."
