Narrative: Landed 27R; exited runway C1 onto Zulu Taxiway. As we made the turn further down the taxiway the aircraft continued to go straight and the nose wheel started to shudder abruptly. Antiskid felt engaged. The aircraft continued to slide towards the left side of the taxiway. Aircraft was sideways with the nose pointed towards the center line sliding sideways. As the Captain regained control and recovered from the slide the aircraft started to slide in the opposite direction towards the right side of the taxiway. As we regained control and were back on centerline I made a PA to the passengers to let them know what happened and that everything was under control and to not be alarmed. I then made a report to ATC (North Ground) to report nil braking action in that turn. We were not Taxiing fast (10kts max 15kts) and had briefed the possibility of slick runways and taxiways. The field condition report did not indicate any issues. The taxiway appeared wet but other than that no significant contamination was noticed. There were several fresh tire makes on the pavement in at least 2-3 of the turns. I reported the braking action as poor in two more turns and Ground seemed not particularly concerned. Pulling into the gate I did a brief walk around and checked the left engine and main gear for damage and found no damage.


Second narrative: After exiting 27R; and making the first right turn on Zulu taxi way as I turned the aircraft continued to go straight and the nose wheel started to shudder. The aircraft continued to the left side of the taxiway and got sideways so that the nose was pointed towards the center line. In the deepest part of the skid the left engine crossed over the taxi line boundary. As I regained control I slowed even more and the aircraft skidded again as it returned to the center line. The FO (First Officer) made an announcement; and reported nil braking action in that turn. During the flight I had pulled up 2 apt condition reports and both showed the same report runway dry taxiway wet. I also got performance for 27R. And briefed the turn off of that we would be well slowed and under control leaving the runway. I believe I had the aircraft to below 10 knots. And the taxiway speed to be less than 15 knots. The taxiway appeared wet in the centerpiece area. The FO checked the left engine for damage at the gate and found nothing. I called the tower to see if we had hit lights; they said that they had not heard anything from the city. I also asked if they had had that area sanded and they said that the city would take care of it.


Synopsis: A320 flight crew experienced nil braking and momentary loss of control when turning on to Z Taxiway from C1 after landing Runway 27R at ORD. The runway was dry; but the taxiway was wet with no braking action problems reported.
