Content:
.2.1-3 NUREG-1555 ` descriptions of the physical characteristics of the surface-water bodies and groundwater aquifers (from ESRP 2.3.1) ` quantitative descriptions of proposed water sources, including groundwater sustained yield, 7-day once-in-10-years low flow, flows (including reverse and regulated) and yields during the drought of record, and low lake levels; estimates of frequency and duration of water-supply shortages (from ESRP 2.3.1 and the environmental report [ER]) ` withdrawals and returns of surface water and groundwater used for plant operation, including rates and sources of water. This should include the different operational modes of the plant (e.g., maxi- mum water intake and consumption, minimum water availability, average plant water use by month, and during shutdown). The information should also include plant effluent quantity and physical characteristics as a function of the different operational modes (from ESRP 3.3.1 and the ER). ` a quantitative description of present and known future surface-water uses (diversions, consumptions, and returns) that are within the hydrological system in which the plant is located and that may affect plant water availability or be affected by plant water use. The following should be included for each use (from ESRP 2.3.2 and the ER): - locations of diversions and returns with respect to the plant intake system - identification of water bodies - average monthly withdrawal and consumption rate. ` a quantitative description of present and known future groundwater withdrawals on the site and for distances great enough to cover aquifers that may affect plant water availability or be affected by plant water use. The following should be included for each use (from ESRP 2.3.2 and the ER): - location, depth, and elevation of wells (total and cased) and water levels with respect to the plant - identification of aquifers - average monthly withdrawal rates. ` operational activities expected to result in hydrologic
