ONS SLRA: Breakout Questions SLRA Section 2.4 - Structural Scoping and Screening Question Number SLRA Section SLRA Page Background / Issue (As applicable/needed)

Discussion Question / Request 1

2.4.4 and SLRA DWG KSLRD-109A-1.1 2-304 SLRA drawing KSLRD-109A-1.1, related to the Keowee Hydro Station Service Water System, contains a Note 7 which states, intake screen is evaluated as a structural component.

SLRA Table 2.4.4-1 shows the structural scoping results for the Keowee Hydro Station and does not list intake screens as a structural component receiving an AMR.

The table does include an entry for trash rack filter.

Is the trash rack filter that is listed in SLRA Table 2.4.4-1 the component that is referred to by Note 7 in the drawing?

Are traveling screens or trash racks used on the intake for any other systems? If so are they in the scope of SLR?
