In this project we are developing a new Offshore Floating Nuclear Plant (OFNP) concept that achieves unprecedented levels of safety. This is a plant that can be entirely built on a floating rig in a shipyard, towed to the site, where it can be anchored a few miles off the coast in relatively deep water, and connected to the grid via an underwater transmission line.
The floating plant has the following features:
- Shipyard construction enhances quality, reduces construction time and provides a reliable modularization approach;
- The plant site can be returned to “green field” conditions after the plant is towed away from the site;
- Plant decommissioning is done quickly and cost-effectively in a centralized shipyard (like the U.S. Navy nuclear submarine and carrier fleets);
- Coastal land usage is reduced to essentially zero, substantially increasing the number of potential sites;
- Safety concerns from earthquakes and tsunamis are eliminated;
- The ocean heat sink can be used to ensure decay heat removal indefinitely, without the need for external power or intervention.
The likelihood of accidents with fuel damage and radionuclide release is drastically reduced, and the need for land evacuation is eliminated. Both features are responsive to the new safety imperatives of a post-Fukushima world. Furthermore, the offshore floating plant concept can transform the economic paradigm of nuclear energy through radical innovations in the way nuclear plants are built, operated and decommissioned.
Suitable sites are selected according to the presence of relatively deep water near shore (this ensures that tsunamis waves are small), cost of other modes of electricity generation (e.g. natural gas, coal), proximity to major load centres (e.g., coastal cities, industrial installations), low frequency and intensity of storms, and distance from major shipping lanes. Many such sites have been identified in established markets such as East and Southeast Asia and the Persian Gulf, but also growing markets like South America and Africa, as well as small island countries, large mining operations, and Department of Defense bases.
