Long time.

@Ashdenpaw1 shiz

like 45 days or so. that is for the big ass nuclear airborne aircraft carrier

@StockPlanesRemastered
It runs on heat exchange, look it up because I don’t want to explain it

@StockPlanesRemastered In theory they could.
Anyways, a nuclear jet still runs much longer than a hydrocarbon jet for equivalent thrust and fuel load.

@Graingy Jet Engines don't run on electricity

@CrestelAeronautics If your engine is a lil bitch, sure ;)

@Graingy
It depends on the engine’s lifespan, you’ll have to replace that before the fuel rods.

@TheUltimatePlaneLover whar

Depends.
If it blows up, you’ll fly forever on two fronts :D

Oooh I remember this project.
Please crash please crash please crash

@StockPlanesRemastered Oh, much longer. Days.
The question is "how many?"

@Graingy ok, well the jet issue is seconds away from being solved, now the jar and cheese thing.

Well not much longer than a conventional one. See jet engines they don't exactly run on electricity. Sadly.

See

@Boeing727200F It's been a month already.

Or you are crashing right now

Until the reactor blows up

@Graingy you got days left my guy. Probably a week at best then you will crash

@MIGFOXHOUND31BSM26 Perhaps.

@Graingy welp, you might be cooked

Anyways, I reckon I'd oughta be bracing for impact right about now.

@Boeing727200F Uh, unfortunately probably not. Nuke jets are a lot spicier than most other forms of reactor.

A 490 MW reactor with 50 kilograms of uranium would therefore burn 1 percent of its fuel each day. Assuming that an accumulation of neutron poisons could be avoided, the missile could fly for several days.

Our engineers have told me quite similar.

great,
quite possibly 20 years if lucky.

@Talon7192 American units I swear
