As one of the world’s largest integrated full-electric propulsion warships, there are many questions about why her grid was conventionally powered, not nuclear, with answers such as cost, maintainability, disposal, and entering nuclear free zones cited as various reasons. This paper, authored by the QE power system designer, poses the idea, why not make her nuclear? Not with a big, costly refit, or billions of pounds, but over a weekend. She has the unique flexibility with her electrical power system for that not to be a crazy notion. Small, containerised nuclear reactors are coming; many are in development and testing, with a number of companies looking to containerise them and place them in neighbourhoods around the world, of course managing the safety case around these modular reactors. If you can drop it off a truck into a neighbourhood and plug it into a grid, then why not fit it into a warship that is already electric and already has a high-power plug on her power system, waiting for such innovation? Ratings of such units are quoted as 2-20MW, ideal for a ship’s microgrid like those on the QE. This paper discusses and suggests the realistic application of small modular reactors for the QE, from a size, system integration and decarbonisation perspective. Containerised, fitted in the hangar, integrated into the power system, slashing the carbon footprint in a weekend, removable if you had a mission to a nuclear-free zone, well capable of providing a large amount of baseline and cruising power, refuellable in a weekend, developed and tested by industry with rapid insertion by a Navy. Cruise nuclear, sprint conventional, perhaps; parallel operation of conventional and nuclear prime movers are eminently possible. It opens up all sorts of possibilities, which will be explored in the paper, from using excess power on board to manufacture e-diesel for the ship to powering Portsmouth when she is in harbour, rather than the other way around. Imagine the Queen Elizabeth carbon neutral, reverse-RASing her escorts with e-diesel and telling her hometown, “When the Queen is in town, your bills go down.”}, url = {http://library.imarest.org/record/11195}, doi = {https://doi.org/10.24868/11195}, }
