Production. New Tennessee Valley Authority synthetic ammonia plant. An operator adjusts a gate valve in the ammonia condenser section of the TVA's new synthetic ammonia plant in the Muscle Shoals area. Ammonia is made here by the high-pressure synthesis of nitrogen and hydrogen. The ammonia thus secured is converted at Muscle Shoals into ammonium nitrate for use in the making of high explosive shells. In addition to the production of munitions, the TVA is engaged in research in many fields, seeking new sources of strategic materials and better ways to utilize them in the war effort
