That depends on how much energy that the space craft reflects. If it reflects all of it, the space craft would not gain any heat at all unless there is some weird quantum effect that would mean otherwise.

Likewise, such a spacecraft could survive the inside of the sun.

I'm not a physicist, but it seems like perfectly reflecting photons in a vacuum is different from being immune to conductive heat transfer in a plasma.

That and reflecting one wavelength vs a wide spectrum.
