report the following: 1. curies of each radionuclide released by quarter and year, and 2. total curies released in each radionuclide category by quarter and year. Some licensees may have surveillance requirements allowing the non-noble gas radionuclides (e.g., iodines and tritium) for some types of batch releases (e.g., containment purge) to be reported with continuous release results. In these instances, the table entries for the affected radionuclides for batch releases should include an appropriate designation (e.g., “*”) and an accompanying footnote describing this situation. Table A-1F, “Gaseous Effluents - Mixed Mode Release - Continuous Mode,” contains a summation of gaseous effluent releases from mixed-modes release points in the continuous mode of release for five radionuclide categories: fission and activation gases, iodines/halogens, particulates, tritium, and gross alpha. Licensees should report the following: 1. curies of each radionuclide released by quarter and year, and 2. total curies released in each radionuclide category by quarter and year. Rev. 2 of RG 1.21, Page 36 8.2 Liquid Effluents The quarterly and annual sums of all radionuclides released in liquid effluents (i.e., routine and abnormal discharges, continuous, and batch) should be reported in a format similar to that of the Tables A- 2A and A-2B. The data should then be further summarized and reported in the format of Appendix A, Table A-2. The following provides additional information on each of these tables. Table A-2, “Liquid Effluents - Summation of All Releases,” contains a summation of all liquid radioactive discharges from all release points and all modes of release. The data are subdivided by quarter and year for each of the radionuclide categories: (a) fission and activation products, (b) tritium, (c) dissolved and entrained noble gases, and (d) gross alpha. The total volume of “primary coolant waste” (typically batch mode releases) before dilution is also
