EC, ODCM, and/or PCP. G. The reviewer compares the proposed calibration methods (i.e., electronic and via the use of the National Institute of Standards and Technology traceable radioactive standards) and frequency of calibrations with the guidelines in Regulatory Guides 1.21, 1.33, and 4.15. The review of instrumentation calibrations considers whether instrumentation response is expected to change given that radionuclide distributions may vary with the operating status of the plant (i.e., normal operation, anticipated operational occurrences, and post- accident conditions). H. The reviewer confirms that adequate documentation exists to confirm the verification and validation of digital computer software used in radiation monitoring and sampling equipment, including software used to terminate or divert process and effluent streams. This evaluation includes software developed by the applicant, purchased through a vendor, or included with the instrumentation. I. The reviewer ensures that the design allows detectors to be replaced or decontaminated without opening the boundary of the process system or without losing the capability to isolate the system or divert effluents to tanks or standby treatment systems (as appropriate). J. The reviewer evaluates, on a case-by-case basis, the use of special system design features or reliance on applicable topical reports, as well as data referenced in the SAR that are applied as technical bases beyond the NRC guidance. 2. The reviewer evaluates programs and procedures described in the applicant’s proposed TS/SREC, ODCM, REMP, and PCP for the PERMISS. The reviewer determines that the applicant’s TS/SREC, ODCM, REMP, and PCP meet the requirements of 10 CFR 50.34a and 10 CFR 50.36a; the Appendix I to 10 CFR Part 50 dose objectives for maximally exposed offsite individual doses (Section II); Sections III and IV of Appendix I to 10 CFR Part 50 regarding the implementation of Appendix I criteria; effluent concentration limits of
