Are NFS effluents above the regulatory limit for uranium-234 and other isotopes?
Nuclear Fuel Services effluents are currently below the regulatory limits for all isotopes, including uranium-234. The NRC license specifies that NFS use a combination of the public dose compliance methods described in 10 CFR 20.1302 (which are the explicit action levels listed in 10 CFR Part 20, Appendix B, or a public dose calculation based on releases). Nuclear Fuel Services calculates public dose if the measured effluent concentrations are above the concentrations listed in 10 CFR Part 20, Appendix B. The radiological constituents in the liquid effluents and air effluents were below the 10 CFR Part 20, Appendix B, levels for the first half of 2009. The concentration of uranium-234 in the liquid effluents is also below the effluent concentrations listed in 10 CFR Part 20, Appendix B, Table 2. The data is presented in the chart below.
