Based on the tech description, Containment Fields seems to primarily be about managing reactor operations, in the fiction. What is the reasoning behind it increasing transport trade capacity? Is it something about making it economical to have faster turnarounds on transport voyages so that a single freighter hauls more loads in a given period of time, given what Containment Fields is supposed to be doing?

The idea is that the fields can be used to stabilize volatile or perishable cargoes.
