Traveling-wave reactors, combat damage, and port access

Could a compact traveling-wave reactor be useful aboard civilian or military ships?

The panel doubts its suitability at the technology's then-current stage, citing possible sensitivity to battle damage and restrictions on nuclear-powered merchant ships entering ports.

A traveling-wave reactor would breed fuel inside its core and then consume that fuel. At the time of the episode, the concept is described as unbuilt, with considerably more theory than demonstrated practice. The concern about warship use is provisional: a system that appears to need tightly controlled conditions might react badly to combat damage. That concern is distinguished from the established usefulness of nuclear power for some naval roles. For commercial ships, a separate obstacle is access to ports that restrict nuclear-powered vessels, with New Zealand given as an example. The discussion does not establish an engineering verdict on a completed compact reactor.
