2.

Please confirm that the single set of values (e.g., nozzle radii, nozzle thicknesses, etc.) used in Enclosure 2 to l3R-14, Plant Specific Applicability, are correct and applicable to both LGS Units 1 and 2. The staff notes that some of these values would be expected to be unit, or nozzle-specific.

Response

The single set of values (e.g., nozzle radii, nozzle thicknesses, etc.) used in Enclosure 2 to 13R-14, Plant Specific Applicability, are correct and applicable to both LGS, Units 1 and 2. These values are minimum design values.
