Sure you can. Russia has blown up multiple experimental nuclear-powered cruise missiles in the last few years [0,1]. It's a political question of tradeoffs, of how much you value technological progress.

America hasn't blown up any atmospheric nuclear reactors in this century. America is also unlikely to learn how to build aerospace nuclear reactors in this century.
