nd design core thermal power, the rated and design gross electrical output, and the rated and design net electrical output (in megawatts [MW]) should be stated. The rated power is defined as the power level at which each reactor would be operated if licensed, and the design power is defined as the highest power level that DG-4026, Page 56 would be permitted by the proposed plant design. The gross electrical output is the power level measured at the output terminals of the generator and expressed in MW(e). The net unit electrical output is equal to the gross electrical output minus the nominal service and auxiliary loads. The following information relating to the reactor-power-conversion system for the proposed plant should be included in the ER: • Reactor-power-conversion system, including the manufacturer and the design status (i.e., certified design or design control document revision). • The number of units and description of each reactor, including (as applicable) reactor type, vendor, architect-engineer, contractor, fuel assembly description, total quantities of uranium, and percentage uranium-235 enrichment. • The planned average irradiation level of spent fuel, in megawatt days/ton. • A description of the turbines and condensers. • A simplified flow diagram for the reactor-power-conversion system. • Service or auxiliary power load. • Type of cooling system. A description of all proposed plant structures, systems, or components is needed to clarify the physical scope of the proposed project for assessing the impacts of building and operation. The description should include, but is not limited to the following: • Plant grade and major structure elevations, using a consistent vertical datum. • Stormwater drainage system (e.g., number, location, and size of temporary and permanent retention/detention ponds, diversion structures, or other hydrological alterations). • Site layout with the location and dimensions (e.g., area and height above
