LFTR-70 Standardized Marine Reactor Module
Fictional or future equipment, with real-world baseline distinguished where applicable
Industrial standard
LFTR-70 is a fictional standardized marine power package manufactured in China, internationally licensed, and certified under Mapmakers’ International Strategic Arms Authority safeguards. Its approximately 70-megawatt electrical output refers to usable net shipboard electrical power. The standardized module can supply ships with very different hull sizes, propulsors and intended operating speeds.
Fuel-cycle and servicing philosophy
The power package is sealed, serialized and designed for whole-module replacement approximately every ten years, with earlier exchange possible for substantial faults. Routine onboard support-system maintenance and safe shutdown are normal shipboard duties; nuclear-material handling, refueling, fuel processing and heavy internal servicing are restricted to qualified guarded shore facilities. The design uses access-control and servicing architecture for proliferation resistance rather than claiming thorium cannot be diverted.
Propulsion flexibility
A single LFTR-70 is the normal commercial fit. One fixed electrical budget can drive a high-capacity container carrier moderately or a smaller fine-lined vessel faster. Twin-module arrangements are technically possible in canon but commercially uncommon because they add nearly another whole power plant without adding another revenue-producing hull. Ships require independent emergency power even if the reactor is highly reliable.
Reality boundary
As of 2026, there is no commercially deployed international fleet of standardized LFTR-70 merchant reactors. The named module, maturity, certification and 2040s commercial economics are fictional hard-SF extrapolations, not verified features of current thorium or molten-salt reactor programs.
