Sure, you could create a float image and fill it with NaN. Of course you must know yourself what to do with it...
Here is a sample plugin:

//--------------------------------------------------------------
import ij.ImagePlus;
import ij.plugin.PlugIn;
import ij.process.FloatProcessor;

public class Make_NaN_Image implements PlugIn {

        public void run(String arg0) {
                FloatProcessor fp = new FloatProcessor(100,100);
                fp.setValue(Float.NaN);
                fp.fill();
                (new ImagePlus("NaN-Image", fp)).show();
        }

}
