The Emergency Dose Calculation Model for Three Mile Island-Unit 1 (TMI-1) was recently revised to take into account the guidance of NUREG/CR-3354: Potentially Buoyant Releases at Boiling and Pressurized Water Reactors. This guidance was applied to the modeling of radioactive steam releases from the main steam relief valves and atmospheric dump valves at TMI-1. This paper presents an overview of the modeling of the steam release, starting with the calculation of steam flow rate at the valve inlet and ending with the ejection of the steam into the atmosphere.
