About three weeks ago, I wrote an article about commercial nuclear ship propulsion. That post introduced Benjamin Haas, a student at SUNY Maritime, who has been leading a design team that is developing the conceptual design for a nuclear powered shipping system.
Ben’s team is not just focused on the ship itself, but on all of the supporting infrastructure that will be required to operate a fleet of commercial ships taking full advantage of the technical capabilities offered by atomic fission in comparison to the current alternatives of diesel engines or combustion gas turbines.
Recently, I received an email from Benjamin that he agreed to let me share with you. He will participate in the comment thread, so if you have any questions about his recent trip or about the progress that he and his team are making with their nuclear ship designs, this would be a good chance to ask.

Subject: NS Savannah Visit with Photos
On Thursday April 3, the senior Naval Architecture class from SUNY Maritime toured the NS Savannah’s Containment Vessel and Engine Room. We donned dosimeters, signed the paper work, saw the steam generators, control drive mechanism, the piping, all the while being lectured on nuclear power and PWR’s by a former senior reactor operator for Calvert Cliffs (a graduate of SUNY Maritime): Clifford Marks.
He showed us the Savannah’s emergency diesel generator and talked to us about decay heat and melt downs. He taught us basic reactor physics and PWR operation. When in the control room, he physically showed us how the controls would have been operated to run the Savannah and how the NRC trained him. It was quite a feeling following the flow of a nuclear reactor with my eyes. My goodness, those PWR operators are SHARP!!
We were lectured on the history of the Savannah, Atoms for Peace, the NRC, and decommissioning by Erhard Koehler, the Savannah’s NRC licensee and MARAD program coordinator, also a graduate of our college. He covered “myths and legends” of the design, such as passenger-cargo ships not necessarily being a design disadvantage at the time (although certainly contributing after the airliners came about), and how MARAD actually wanted a bigger, faster vessel, but only got a limited amount of funds appropriated.
Giving a presentation on the Savannah about a nuclear shipping startup and national policy is very tantalizing… Probably in a few years when I have a white paper like Leslie Dewan’s group at Trans Atomic Power.
We had lunch on the vessel, pizza, in the salon. A large container ship passed by. The Alumni (two of our professors and the two Savannah workers) sat together talking while the cadets were in their own groups.
We saw demonstrations of Geiger counters using fiesta ware, uranium glass, and an old radium dial clock. It was just like all the videos I have watched. The Radiation Safety Officer was happy I knew it was a “pancake probe”. During the briefing, he used the term “pain” to describe paper work. People did not know what that meant and the thought entered my mind of radiation workers having blood drawn to measure internal exposure, although I think they take fecal samples? It was a funny moment nevertheless.
I am planning to write an article about the visit. We did not have the chance to debrief on our impressions since we drove straight back to NY. Some of the students I talked to were so very impressed and grateful for the visit. My design team had been looking forward to this trip since I told them I would get us a visit last year. My impressions is that most everybody was tired from a full day of learning.
We literally experienced up close a nuclear reactor and nuclear-powered ship, whose license and upkeep are still relevant.
I have attached some pictures from the trip. You finally get to see a picture of me and my design team.
