Narrative:
Callback conversation with reporter revealed the following information. Reporter was working local at ord. TRACON released approaching base leg then the reporter released air carrier X of runway 9. He thought there would be sufficient sep between the aircraft if air carrier X made a normal climb rate, however, he didn't climb as expected and xed over the mlt aircraft by 400' and within 1 mi. WX was 400' overcast and 1 mi visibility. Reporter has 21 yrs in ATC with 12 yrs in radar. Facility filed report.
