Showing the Head

Publicity photo from Consumers Power; accompanying caption reads: "Showing the 28-ton 'head,' or top, of Consumers Power Company's Nuclear Plant reactor itself. The reactor in Michigan's first operating nuclear power plant rests below this head, which the plant operators remove at scheduled times for certain tests and maintenance work.
"The plant is being used in a research and development program, and any of its 50,000 kilowatts of power not needed in the program is sent to Consumers Power Company's 900,000 electric customers in 61 counties throughout Michigan's Lower Peninsula."
