Subject:

Required Reporting of Effluents per 10 CFR 70.69 _

As required by 10 CFR 70 59, Framatome is reporting discharges of radioactive materials in the effluents from its nuclear fuels fabrication plant on Hom Rapids Road in Richland, Washington for the period from .July 1 through December 31, 2020.

The total exposure from all stacks Is 1.64E-05 _mrem Doses were detennined using CAP88 Version 4.

If there are any questions, please contact me at (509) 375-8355.

- The average concentration of insoluble uranium for the 6-month period was 23.5 ppb.

These constituents are analyzed chemically via Inductively Coupled Plasma/Mass Spectroscopy (ICP/MS) as opposed to radiation counting. Laboratory _detection limits for uranium and Tc-99 are generally 1 ppb and 5 ppt, respectively.
