Content:
such as those listed in Attachment B of this appendix, include, but are not limited to, radioactive waste systems, building sumps and drains, spent fuel storage pools and other systems where, based on operational experience, the likelihood of such releases could occur. Typical systems and operational experience instances are included in Attachment C of this appendix. II. General SSC Screening If the general screening indicates review is warranted, review the FSAR description provided to determine if the applicant has included design or operational features to address compliance with 10 CFR 20.1406. Request additional information or discuss with the Radiation Protection Branch responsible for reviewing SRP Section 12.3, if additional information is needed. 1. Systems/Components: a. Does the system contain or potentially contain radioactive materials? (See RG 4.21, Appendix A for examples) AND; b. Is the system separated from the environment by a single barrier?  Tank/Sump with an exterior wall or floor  Single walled pipe located in an area not accessible for inspection (buried pipe trench, pipe drains, etc.) OR; Are portions of the system located outside of a structure designed to contain a release of radioactive materials? OR; A-5 Revision 5 – September 2013 c. Has operational experience demonstrated that the system or components has previously resulted in a release of radioactive materials? 2. Structures: a. Does the structure envelope a system or components that contain or potentially contain radioactive materials? AND; b. Are there any below grade penetrations (e.g., piping, conduit) to the environment? OR; c. Are there any below grade concrete joints (e.g., floor to floor, walls to floor) that connect to the environment? OR; d. Does the structure contain radioactive materials that are separated from the environment by a single barrier? (retention pond with liner, or radioactive waste pipe running between buildings) A-6 - Attachment B Revision 5 –
