Subject:
Addition of Iodine Isotopes to the Calculated 50 Year Organ Doses at the VNC Site Boundary From 100% Release of the Isotopes in GETR Pool, Canal, and Primary Water i
Reference:
Letter, R. W. Damitzel to Robert A. Clark dated August 6,1980 De:tr Mr. Clark: Iodine isotopes were not included in the isotope inventory used in the referenced submittal. Water sampic analyses of the GETR primary and pool showing various concentrations of I-131 and I-135 during operations in mid-1977 were obtained after issuing the referenced letter. The highest l reported concentrations of these isotopes were used to calculate I-131 and I-135 activities in the total 39,000 gallons of primary, pool, and canal wate rs. The iodine isotope activities are included in the attached, revised table of total curie levels in GTR waters during normal operation. Calculations which include iodine isotopes and the revised organ doses are given in the attached Table 2. The 50 year organ doses remain within l IGP-9 dose limits to members of the public. i Very truly yours, p- ~ ~-~n nf U , vmc .C C hi;? j fJOTARY PUBLIC - CAUTCPN>A (Q(~2 R. W.
