Fission product transport analysis. Quarterly progress report, July--September 1977. Task 2. [PWR, BWR]

Technical progress during this quarter consisted of completing and checking the model for emergency core cooling system (ECCS) water scrubbing of fission products for inclusion in the TRAP code, identifying fission product source terms data and information for initial use under assumed meltdown conditions, specifying the thermal-hydraulic conditions to be considered for fission product transport in postulated meltdown accidents, and choosing a control volume framework for initial use in development of the transport model for meltdown conditions.
