The report must specify the quantity of each of the principal radionuclides released to unrestricted areas in liquid and in gaseous effluents during the previous six months of operation. 1. Did the licensee submit the report within 60 days of the end of the reporting period i.e., January 1st or July 1st? (10CFR40.65(a)(1)) Yes Z No III Comments: The Semi-Annual Effluent Monitoring Report for the 1st half of 2015 for the White Mesa Mill was submitted on August 29, 2017 Page 1 of 8 2.

The concentration values given in Columns 1 and 2 of Table 2 are equivalent to the radionuclide concentrations which, i f inhaled or ingested continuously over the course of a year, would produce a total effective dose equivalent of 0.05 rem (50 millirem or 0.5 millisieverts)." Comments: Sampling results were below ECLs for all analyzed isotopes at all monitoring locations for the last four quarters, and for the year. See the attached Particulate, Radon and Gamma Screening analysis for a summary of quarterly and annual data and a calculated dose at each of the high-volume air stations. Page 2 of 8 , 4.

Subsequent readings were lower. The high reading resulted in a Rn dose as well as an aggregate radiation dose above the plant ALARA goal, and above the Rn ECL for that location, but below the 100 mrem regulatory limit.

Calculated ECLs account for partial ingrowth using methodology in EPA 520/1-88-009 p. 2-20. Calculated ECLs result in maximum exposure of 25 mrem/yr vs. 50 mrem/yr using Table 2 value. Regulatory limit is 100 mrem/yr. See the attached Particulate, Radon and Gamma Screening analysis for a summary of quarterly and annual data and a calculated dose at each of the high-volume air stations. 10.

Yes 111 No El Comments: See the attached Particulate, Radon and Gamma Screening analysis for a summary of quarterly and annual data and a calculated dose at each of the high-volume air stations. The 4th quarter 2016 reading at BAV-8 was high. During the 1st half of 2017, the radon readings dropped.
