A nuclear lightbulb ..... would be operated at such high temperature (approx. 25,000°C) that the vast majority of the electromagnetic emissions would be in the hard ultraviolet range.

[Transparent aluminum] remains solid up to 1200°C (2190°F).

Why would it? What problem does transparent aluminum potentially solve?

 

Please make some kind of connection between the two ends of your conjecture, and have them within reach of each other.

Nuclear light bulb rocket would cool the quartz reactor jackets with the propellant in much the same manner as metal rocket nozzles are cooled by propellant .https://aviation.stackexchange.com/questions/17266/how-are-rocket-engine-nozzles-able-to-survive-very-high-temperatures-without-mel

 Transparent aluminum melts at a much higher temperature than quartz which is the current material of choice would transparent aluminum be a better choice?

At ~25,000 ºC the peak wavelength of emission is at ~116 nm, and the transparent aluminum transmission cutoff is ~200 nm, so it would tend to block/absorb much of the light you want transmitted.

I think pretty nearly everything is opaque at 116 nm

Quartz transmits down to ~150 nm, so the transparent aluminum is worse

Back to the drawing board...
