charged during periods of liquid effluent releases. Licensees should include information describing how this value is calculated in either the ODCM or the ARERR. Because of the potentially high volume and extremely low activity of this type of waste, it is recommended the volume and dilution data be summarized separately from the higher activity waste described in the previous paragraph. Licensees should report dilution flow rates during periods of release (before effluent is discharged to the receiving water body) as described above. If calculated differently than described above, the licensee should describe the method of calculation. Licensees may choose to report near-field dilution if dilution by the receiving water body is taken into account. Licensees may report the average, minimum, and/or peak river or stream flow rates if applicable. Table A-2A, “Liquid Effluents—Batch Mode,” contains a summation of liquid effluent discharges in the batch mode of release. The table is divided into four radionuclide categories: fission and activation products, tritium, dissolved and entrained gases, and gross alpha. Licensees should report the following: 1. curies of each radionuclide and gross alpha discharged by quarter and year, and 2. total curies in each radionuclide category by quarter and year. Rev. 2 of RG 1.21, Page 37 Table A-2B, “Liquid Effluents—Continuous Mode,” contains a summation of liquid effluent discharges in the continuous mode of release. The table is divided into four radionuclide categories: fission and activation products, tritium, dissolved and entrained gases, and gross alpha. Licensees should report the following: 1. curies of each radionuclide and gross alpha discharged by quarter and year, and 2. total curies in each radionuclide category by quarter and year. 8.3 Solid Waste Storage and Shipments Appendix A, Table A-3, summarizes the solid radioactive waste (low-level waste) shipped from the site during the reporting period. It is
