00B Reviston 00 PURPOSE:
Document the Screening Evaluation Work Sheets (SEWS) forthe DG FUEL OIL STORAGE TANK4103, EQUIPMENT NUMBER 82-43.
This SEWS has been prepared as part ofthe commitment to use the SQUG (GIP) methodology to document the seismic adequacy of SSEL components.
~
CONCLUSION: Calculation S20.6-YD-TANK01 analyzed this tank for the design basis load combination of DL+ seismic+ variable tank fill.Therefore, the DG Fuel Oil Tank is seismically adequate.
