the reason your airbags didn't deploy is the sensor is below the area hit. (they are located behind the bumper) looks like you hit mid headlight and hood. in order to determine if it's salvageable you'll need to remove the hood, fender lights to see how far it's been pushed in. most times a good body shop can pull the damage out.
i've fixed a few cars with similar damage. one i had used my truck to pull the radiator support out, then used the scissor jack from the trunk to push the bent AC condenser back into shape.
just from the picture, looks like you'll need a bumper, mount, foam backing, bumper cover, turn signal, corner light, headlight, grill, fender, hood, hood hinge(possibly bent) and windshield (and radiator as you stated, as well as possibly the fan, and AC condenser and what not). what you'll want to do is price those parts from a junkyard. then you can determine if the car is worth saving. if you total everything and it comes up over $1k it may not be worth saving. i've bought some parts cars for $2-400 just because the front sheetmetal was nice, and the rear was hit hard. but then again i'll take EVERYTHING i can. motor, trans etc.
this is one of the car's i fixed. blown engine. and a wall fell on it. cost me $200 for the hood, fenders and lights.
just for laughs i put on a BZ touring front headlights and grill.
