ting the requirements of GDC 61 provides assurance that releases of radioactive materials during normal operation and AOOs, including adverse vacuum conditions on system components, will not result in radioactive material concentrations and radiation exposures that exceed dose and concentration limits specified in 10 CFR Part 20. In addition, meeting this requirement will help ensure that the LWMS will continue to perform its functions under postulated accident conditions. 11.2-19 Revision 5 – January 2016 Using the guidance of RG 1.143 provides reasonable assurance that the assigned safety classifications for structures housing the LWMS and its components comply with the requirements of GDC 2 and 61 and the guidance of RG 1.143 for natural phenomena and man-induced hazards. Using the guidance of SRP Section 2.4.13 and BTP 11-6 (as referenced herein), and using the analysis of RG 1.143 in assigning the safety classifications to SSCs of the LWMS for design purposes, provide reasonable assurance that the necessary information is available to identify the amounts of radioactive materials contained in the LWMS and assess the radiological impacts during postulated accidents. 7. Radioactive materials should be processed, handled, and stored using equipment, methods, and procedures that avoid or minimize potential releases of radioactivity in the event of a fire. GDC 3 relates to fire protection features for SSCs important to safety and can be used to provide guidance for LWMS design features and operational safeguards to prevent, for example, the generation of exothermic reactions and explosive gas mixtures through the introduction and mixing of chemical additives with ion-exchange resins. Using GDC 3 to review systems important to safety provides assurance that the LWMS is protected from the effects of explosive gas mixtures and exothermic reactions and that the functions of its subsystems and components will not be compromised in meeting the effluent discharge
