Director, Office of Nuclear Material Safety and Safeguards One White Flint North 11555 Rockville Pike Rockville, Maryland 20852-2738 License SNM-1227 Docket 70-1257
Subject:
Required Reporting of Effluents per 10 CFR 70.59 As required by 10 CFR 70.59, Framatome is reporting discharges of radioactive materials in the effluents from its nuclear fuels fabrication plant on Horn Rapids Road in Richland, Washington for the period from January 1 through June 30, 2018.
During the first six months of 2018, K46 exceeded 10 CFR 20 Appendix B Table 2 Effluent Concentrations for air. Corrective Action Report 2018-7738 was generated to address this issue. The release was less than five times the Table 2 limits and did not exceed the ALARA limit of 10 mrem. Initial dose calculations utilizing CAP88 Version 4 indicate potential TEDE to MEI of 9.13 E-5 mrem from this stack release.

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
