The phrase "an open fuel" is correct and usable in written English.
It can be used in contexts discussing types of fuel that are accessible or unrestricted, often in relation to engines or energy sources.
Example: "The new regulations allow for the use of an open fuel, promoting innovation in alternative energy solutions."
Alternatives: "a free fuel" or "an unrestricted fuel".
The United States has a particularly acute problem due to its adherence to an open fuel cycle and its large number of reactors.
If Congress were to enact an open fuel standard that required new cars to be warranted to run on all-alcohol fuels, including methanol, natural gas could compete with oil in the liquid fuels market.
Assuming that the deployment of fast reactors occurs beyond the middle of the century, the article focuses on the comparison of an open fuel cycle strategy with a closed fuel cycle strategy where plutonium is recycled.
It demonstrates that an open fuel cycle would require about 16% more natural uranium, would have a bigger environmental footprint on the "non radioactive indicators" and would produce a higher volume of high level radioactive waste.

They carry a tool that allows them to open fuel tank flaps even when they're locked.
Current open fuel cycle reactors, however, result in low energy efficiency and produce large volumes of nuclear waste.
NEST is also Excel based and can be used to evaluate nuclear reactor systems using the open fuel cycle, MOX (mixed oxide) fuel recycling and closed cycles.
In the so-called open fuel cycle (common in the United States, Sweden and some other countries) spent fuel is generally disposed of as waste that will remain radioactive for 200,000 years.
There are several types of fission reactors operating in the world adopting generally the open fuel cycle which considers the naturally available fissile nuclide, viz., 235U.
