Callaway Plant looking to the southeast.		Callaway Plant power block. The reactor containment building is 205 feet tall and 150 feet in diameter. It is constructed of reinforced concrete and steel four feet thick.		View high above Callaway Plant’s 553’ tall cooling tower—the second tallest structure in Missouri behind the Gateway Arch. The white plume coming out of the top of the structure is clean water vapor, not smoke or steam.

Acreage surrounding Callaway Plant. AmerenUE owns 7,200 acres around the plant. The plant utilizes 900 acres and the remaining 6,300 acres are part of the Reform Conservation Area managed by the Missouri Department of Conservation.		Callaway Plant looking to the northeast. The cooling tower cools approximately 585,000 gallons of water per minute when the plant is operating at full power.		The cooling water intake structure on the Missouri River. The plant is located five miles north of the Missouri River on a plateau 300 feet above the average river level.

Plant switchyard looking due north. Nuclear plants are among the safest workplaces in the U.S. The white plume coming out of the top of the structure is clean water vapor, not smoke or steam.		Callaway Plant’s power block. Callaway Plant is one of 104 nuclear plants in the U.S. and 429 nuclear plants in the world.		345 kV transmission line leaving the power plant. Callaway Plant generates enough electricity to supply 780,000 average households every year.

345 kilovolt transmission tower. Callaway Plant’s generating capacity is 1,190 megawatts (net).		193 fuel assemblies inside the reactor vessel at Callaway Plant. Raising the control rods enables the nuclear reaction to start. Lowering the control rods shuts the reactor down.		Refueling operation, which occurs every 18 months at Callaway Plant. During a refueling, nearly half of the 193 fuel assemblies are replaced with new assemblies.

Refueling operations. Nuclear fuel is remarkably efficient and abundant. One 7-gram uranium fuel pellet provides as much energy as 17,000 cubic feet of natural gas, 149 gallons of oil or 1,780 pounds of coal.		Refueling operation with the reactor vessel head on a stand. All of the spent fuel used at Callaway Plant from nearly 25 years of operation fits in a space about the size of a tennis court.		Reactor vessel head on a stand during a refueling outage. Callaway Plant takes about 30 days to refuel. The average refueling outage across the U.S. is 40 days.
