Content:
alarms and terminating effluent releases or isolating processes; bases for in-plant effluent dilution; and diversity of components used for normal operations, anticipated operational occurrences, and postulated accidents. B. Location of radiation instrumentation, monitors, and direct readouts, including the proposed locations and interface with skid-mounted radiation monitoring equipment. C. Location and bases of selected sampling points and sampling stations. D. Methods used to convert raw instrumentation readings into meaningful results to identify radioactivity or radionuclide concentrations monitored or sampled for normal operations, anticipated operational occurrences, and postulated accidents. E. Measurements, analyses, or determinations made, including the bases for the interpretation of sample analysis results relying on the use of surrogate radionuclides, as easy-to-detect in accounting for the presence of hard-to-detect radionuclides and gross beta-gamma concentrations or via the measurements of specific radionuclides. Instrumentation calibration procedures should consider 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). F. Types and locations of annunciations and alarms and actions initiated by each, and confirmation that once tripped by an alarm setpoint, the system properly initiates and completes the expected action, such as terminating or diverting a release or process. G. Provisions for purging sample lines and minimizing process and effluent volumes to waste collection systems, as well as the bases for the sampling and analysis program, including the frequency of sample collection and analysis. H. Expected relationships and interpretation of results between monitoring instrumentation readouts, sample analytical results, and plant operations. I. Descriptions of
