Content:
id, wet, and solid wastes are processed and stored (e.g., use of HEPA and charcoal filters) is conducted using the guidance in SRP Section 9.4 and SRP Section 11.5 for instrumentation used to monitor, control, and sample radioactive effluent releases. The review also addresses design features of ventilation systems used to vent tanks and process equipment (e.g., via the use of high efficiency particulate air and activated charcoal filters). 9. The review of radiation monitoring instrumentation and controls used by the SWMS, including provisions for automatic control features and interdependence with parameters other than radioactivity (e.g., fluid level, valve position, and system pressure, flow rate, and temperature), is performed using the guidance in SRP Sections 11.5 and 9.3.2, “Process and Post-accident Sampling Systems.” The review addresses the types and placement of such sensors in plant systems, basis of operational ranges and 11.4-9 Revision 4 – January 2016 qualification of sensing elements in supporting the functions of radiation monitoring systems. The review considers functional interdependence and logic in alarming, terminating and/or diverting process or effluent streams to comply with doses and effluent concentration limits under 10 CFR Part 20 and design objectives of Appendix I to 10 CFR Part 50. The review also addresses design features to prevent radioactive contamination of otherwise nonradioactive plant systems in avoiding unmonitored and uncontrolled releases of radioactive materials to the environment using the guidance in RGs 1.143 and 4.21 and IE Bulletin 80-10, “Contamination of Nonradioactive System and Resulting Potential for Unmonitored, Uncontrolled Release of Radioactivity to Environment.” 10. Review of technical specifications (TSs) is performed using the guidance in SRP Chapter 16, and Section 11.5, as they relate to administrative controls and programs on radioactive effluent controls and monitoring and implementation of
