resulting effects on the development of the RETS/SREC and ODCM. The staff’s evaluation and conclusion of the acceptability of the augmented programmatic elements is addressed in SRP Section 13.4 and relevant requirements and guidance identified in this SRP section for the systems and components identified in the supplemental or new programmatic elements. 5. To the extent not covered in SRP Sections 11.2 and 11.3, the design of sampling components and sample tanks and their placement in buildings should include provisions to reduce leakage and facilitate operations and maintenance. The design and layout should be compared to the guidance of RG 4.21 and RG 1.143 for liquid wastes and venting of tanks and components. RG 1.143 describes design guidance acceptable to the NRC staff related to seismic, safety, and quality group classifications and QA provisions for LWMS and GWMS subsystem interfaces with PERMISS components. Compliance with RG 1.143 provides reasonable assurance that the assigned safety classifications for structures housing the LWMS and GWMS and their components comply with the requirements of GDC 2 and GDC 61. 6. For liquid and gaseous process radiation monitoring equipment not covered by the ODCM, the review should confirm that the applicant, even when referencing a DC, provides information describing methods and procedures that will be used in deriving lower limits of detection or detection sensitivities, and set-points (alarms and process termination/diversion) for process radiation monitoring equipment. The review should 11.5-36 Revision 6 – January 2016 determine whether the applicant has made specific commitments to develop a plant- specific process and radiological sampling and analysis plan for systems not covered by the ODCM, including provisions describing sampling and analytical frequencies, and radiological analyses for the expected types of liquid and gaseous samples and waste media generated by the LWMS, GWMS, and SWMS. The review should
