Content:
adionuclide distributions and concentrations to ensure that the highest potential radioactive material inventory is selected among the expected types of liquid and wet waste streams processed by plant systems. Conceptually, the health physics staff will confirm whether the applicant’s approach in developing the radioactive source term has considered the following: A. reactor system and thermal power consistent with the design certification, B. description of system and components assumed to fail as permanently installed process equipment, including the interface of skid-mounted mobile processing systems, as justified, BTP 11-6-8 Revision 4 – January 2016 C. process or waste streams selected, D. location of failed tank and components in plant buildings and at outdoor locations, if applicable, E. nominal volume of failed tank and components, F. failed fuel fraction applied in deriving radioactivity inventory, if different than default value of SRP guidance, G. radionuclide re-concentration factors applied in deriving radioactivity inventory, as mandated by the selected process or specific waste streams, H. assumed radionuclide distributions and concentrations and total radioactivity inventory in tanks and components of systems located indoors and outdoors, I. for systems located indoors, description of the release mechanism starting from the room or cubicle housing such systems to the underlying ground immediately below the building’s foundation boundary, J. for systems located outdoors, description of the release mechanism starting from the retention basin or diked area to the nearest point of entry into the site’s surface water runoff discharge system and location of its outfall in unrestricted areas, and groundwater if a pathway exists, K. assumed dilution, retardation factors, and travel times in instances where groundwater or surface water models were not used to describe the transport of radioactivity from the site to the point of entry in unrestricted
