Dear Mel:

Enclosed for your records is the information telecopied to you on March 25 (retention factors on March 26). You should find enclosed six tables giving calculated results for:

e Locational distribution of three fission product species for Surry V sequence (from Volume V, BMI-2104) e Locaticnal distribution of fission product groups for Peach Bottom AE sequence s Time dependent release for fission product groups -- Peach Bottom TC-Y '

s CORS0R predicted release from core region for Surry AB and TMLB' -- with and without control rods e Cumulative aerosol mass retained in RCS for Surry AB and TMLB' -- with and without control rods e Retention factors in RCS for AB and TMLB' with and without control rods.

I hope you found this information useful.

Sincerely, James A. Gieseke Physico-Chemical Systems Section JAG:drr cc:
