Aerosol behavior modeling for fast reactor safety. Quarterly progress report for July--September 1975

Progress at Battelle has been made in three general areas. A sodium oxide aerosol generator has been designed and constructed for use with a Millikan cell apparatus in studying sodium oxide agglomerate characteristics. The experimental design, rationale, and procedure are discussed in detail. Also, further improvements have been made in the HAARM-1 aerosol behavior code and a second generation code, HAARM-2, has been developed. Furthermore, a preliminary comparison between the PARKISEKO-III code and the HAA-3B model has been performed. Results for a particular case are discussed. (auth)
