It's really weak not to raise this if the board is no flush with no realistic straight possibility - and Im guilty of weak tight river calls. You are only worried about a set - which is not out of the realm of possibility, but also not the most likely of villain's holdings.

The point of calling with AK TPTK on the river is because such a wide range of hands that would give action to the river can beat you. The most likely of these hands is two pair. Since the river eliminates any risk from these hands, I think a value bet/raise is in order. Aces up will give you action and so will two pair hands that hit the King. Im willing to play a larger pot once the King hits. Of course a reraise allin will make you puke, but against most opponents at SSNLHE (at least up through 200NL) you will be ahead with AK much more than you would be behind.
