RG 4.21, “Minimization of Contamination and Radioactive Waste Generation: Life Cycle Planning,” June 2008. BTP 11-6-21 Draft Revision 4 – August 2014 APPENDIX A TO BTP 11-6 SOURCE TERM RADIONUCLIDES Table 1 below contains a list of radionuclides that should be included, at a minimum, in any assessment of an accidental release of radioactive material from liquid waste tanks. The list includes all those nongaseous radionuclides listed in ANSI/ANS 18.1-1999, “Radioactive Source Term for Normal Operation of Light Water Reactors.” This standard is the basis in developing predicted reactor coolant and steam concentrations and annual effluent releases presented in FSAR Chapter 11 and contained radioactive sources in plant systems presented in FSAR Chapter 12. In addition to those radionuclides, the table also includes I-129 and Tc-99 because they are fission products that can escape into the reactor coolant and, when they are released into the environment, they move readily with groundwater with little retardation and radiological decay.
