Narrative:
Aircraft B737-800; secondary flight control failure: flaps will not extend: performed flap-less landing. Flap position indicator stopped between '0' and '1' and le (leading edge) transit amber annunciator light on. Overhead le lights show extended.flap fail to extend from '0' setting to '1'. This happened while on intercept for the approach ILS runway xx. Immediately asked ATC for a hold due to technical issues and needed time to work QRH checklist. ATC instructed to hold at zzzzz way point as published. We then worked the QRH checklist; including an attempt to extend flaps via alternate flap system. Then set new vref; set brakes; checked runway length; briefed crew; [advised ATC]. At this point I took control of the aircraft and became pilot flying. Proceeded to shoot approach; landed with no further issues and taxied to parking stand. Once parked; instructed the ground crew to only chock nose wheel; due to possible hot brakes and tires. Landing weight was 60T; vref 190 kts.; runway required 8100 ft. (11034 ft. Available from glide slope); touchdown speed 180 kts. (Max tire speed 195kts.); autobrake 3; max reverse thrust.
