Items from the Savannah (1960s)

The above photo shows two informational booklets given to passengers aboard the Savannah, a numbered button used by crew members, a circular red luggage sticker, a light blue luggage tag, a luggage label. 

The History of the Savannah

The N.S. Savannah (named after the first steamship to cross the Atlantic) was the world’s first nuclear powered merchant ship. It operated as both a passenger ship and a cargo ship carrying up to 60 passengers and 9,250 tons of cargo. Todd Shipyards in Galveston, Texas served as her home port.*

The Savannah was a joint effort of the Maritime Administration of the Department of Commerce and the Atomic Energy Commission. Congress approved the project in 1956, and the ship was launched July 21, 1959 . The maiden voyage, which began in August 1962, took the Savannah from Yorktown VA to Savannah, Georgia. 

A ship's "deck officers" were traditionally paid more than its "engineering officers" (the two groups were represented by different unions), but this was not the case on the Savannah.  The latter's engineering officers had BS degrees in engineering from the U.S. Merchant Marine Academy at Kings Point, NY., and had spent two years at the Babcock and Wilcox facility in Lynchburg, Virginia receiving training for their reactor and senior reactor operator licenses. The salary issue resulted in everyone walking off the ship and a shutting down of the Savannah's operations. In May of 1963, American Export Isbrandtsen Lines took over from the original contractor, States Marine Lines, and the troublesome crew was replaced.

Unfortunately, the Savannah operated at a loss and the ship never gained the full support of the Maritime Administration. The decision to mothball the Savannah came in 1967. For many years the Savannah was located in Charleston South Carolina where she operated  as a floating museum. In July of 1994, the Savannah was towed from Charleston to the James River Reserve Fleet in Norfolk Virginia, and moored alongside the  Sturgis, a floating Army Corps of Engineers nuclear power plant.

Ship Dimensions:  596 feet long and 78 feet across at the beam. 

Reactor Details: 69 MW. The pressure vessel, the heat exchanger, the pressurizer, etc, were located inside a hemispherical steel containment vessel located just forward of the bridge.  The bottom half of the vessel was encased in concrete while the top half was enclosed in steel and redwood timber. Water cooled.  Heat from the reactor produced steam which turned the turbine and the propeller shaft. 

Fuel: 682,000 enriched uranium oxide pellets, enough for 3 and one half years of normal operation..

Radiation Exposure Rates and Dosimetry

The 1962 Health Physics surveys indicated that the highest exposure rates (up to 210 mR/hr) were found in the charge pump rooms.

Passengers were not monitored. Crew members wore Oak Ridge National Laboratory film badges. During the May-December 1962 period, the highest weekly dose was 700 mrem. The average was less than 5 mrem per week with only two individuals exceeding 20 mrem in a week.

Trivia

The Savannah had its own servant  -  a barge, the “Atomic Servant” functioned as a maintenance, refueling and waste processing facility for the Savannah .

 

* Galveston at that time was a rough and tumble town where the Texas Rangers struggled to control the illegal gambling and prostitution. Technically the town was "dry," but there were plenty of private clubs (with peep holes in the door) to provide the crew with alcohol. Should they want it, that is.
