Preparing the ports

are wire outlets. Port 1 is a pressure port which permits the box to be pressurized and depressurized by turning a ball valve on or off. We chose a low cost valve, but recommend using a better valve. 

The case walls are thin plastic, so do not stress them too much when tightening fittings. 

You can also epoxy the interface between the plastic box surface and the fittings on both the outside and inside of the box to help further ensure a leak free fitting. 

Silicone could be used instead of epoxy here since it maintains flexibility better when exposed to temperature changes and weathering. Epoxy tends to delaminate when temperatures change and will expand and contract the connections.

The use of nuclear reactors to drive ships has been promoted particularly among nautical nations. Commercial marine reactors include the Savannah in the USA, the Otto Hahn in Germany, and the Mutsu in Japan. They experienced marine operation but unfortunately the development had been cancelled after several years. Nuclear-powered ships require fi ee access to ports in the world, but unfortunately there were no sufficient number of ports to make the marine reactor s operation feasible. Some countries had accepted to prepare the ports, but doing this would still take time.
