Narrative:

While taxiing eastbound on taxiway south, after exiting the deice area, I attempted to comply with post deice procedure for B757 aircraft. En route to the active runway 27L, selected a position on taxiway south that appeared to be free of contamination, on which to accomplish post application run-up procedure. As power was applied to the right engine (60% N1) aircraft nose moved off taxiway centerline to the left. Immediately counteracted with nosewheel steering and brakes. Both of these actions had no appreciable effect. Thereafter, selected reverse thrust with both engines which stopped sideways aircraft movement. I continued to apply reverse thrust and returned aircraft to taxiway centerline. Notified ground control immediately of the extreme poor taxiway conditions. Completed engine run-up procedure on the active runway, where surface conditions were acceptable.
