Content:
the discharge point. – A description of controlling structures and flow patterns, residence times, rate of temperature changes, evaporation rate, and seepage rate for any cooling-water reservoirs or discharge canals. – Maintenance procedures and frequency for the intake and discharge structures (e.g., dredging or mucking, biofouling treatment, screen maintenance, and pump maintenance), including proposed waste- or debris-disposal practices. DG-4026, Page 59 – Maintenance procedures and frequency for the stormwater-management system, including proposed waste- or debris-disposal practices. • Land Interfaces – Maintenance procedures and frequency for transmission corridors and switchyards, roads, parking areas, rail lines, and other infrastructure, including proposed waste- or debris- disposal practices. • Air Interfaces – Location, including elevation, of plant vents and other exhaust vents. The number and capacity of diesel/turbine generators and other emission sources, estimated frequency of operation, and associated emissions. 3.4.2 Radioactive Waste Management Radioactive waste-management and effluent-control systems should be designed so as to control and maintain the radioactive material released annually in liquid and gaseous effluents from normal operation, including anticipated operational occurrences, to a level that is as low as is reasonably achievable in accordance with the requirement of 10 CFR 50.34a, “Design Objectives For Equipment To Control Releases of Radioactive Material in Effluents-Nuclear Power Reactors.” The information should be taken from the final safety analysis report (FSAR) and summarized in the ER. References to the FSAR sections should be made in the ER. The following information relating to the radioactive waste- management system should be included in the ER: • a summary description of the liquid and gaseous radioactive waste-management and effluent-control systems; • process and instrumentation diagrams and
