Space is pretty empty, so it is not too likely to hit debris. Micrometeorite protection would be by multiple layers of the hab walls, using Kevlar much like at the ISS. The radiators need to be fault tolerant, so individual lines can be switched off to avoid coolant loss. The reactor is protected in its casing.

A forward looking Radar system will probalby scan the space ahead to detect larger sized particles, to avoid them. By the way, this vehicle has not a real 'front', it is flying sideways for most time in the cruise.
