SO.OSEWS96-04 Revishn 00 PURPOSE:
Document the Screening Evaluation Work Sheets (SEWS) forthe DSA/DG¹102 START AIRTANK¹4, equipment number 96-04. The emergency diesel air start tanks, ID numbers TANK-96-04 to 08 and TANK-96-31 to 35, are the same tank having the same anchorage. This calculation evaluates the anchorage for all these similar tanks.
This SEWS has been prepared as part ofthe commitment to use the SQUG (GIP) methodology to document the seismic adequacy of SSEL components.
CONCLUSION: The TANK-96-04 anchor analysis concluded the anchorage can withstand 4.207 times greater the seismic demand. The allowable loads forthese cinch anchors are referenced in calculation SO.OSQUGANCHOR. The cinch anchors passed the tightness check for tank 96-04.
Therefore, the SQUG outlier for 96-04 is resolved.

DSA/DG ¹102 START AIR TANK¹1 Building TB Manufacturer, Model, Etc.:
Floor El.: 261.00 Room, Row/Col: DG 102 RM BASIS: External analysis
- 1. The buckling capacity of the shell of a large, flat-bottom, vertical tank is equal to or greater than the demand.
- 2. The capacity of the anchor bolts and their embedments is equal to or greater than the demand.
- 3. The capacity of connections between the anchor bolts and the tank shell is equal to or greater than the demand.
- 4. Attached piping has adequate flexibilityto accommodate the motion of a large, flat-bottom, vertical tank.
- 5. A ring-pe foundation is not used to support a large, flat-bottom, vertical tank.
Yes Yes Yes Yes N/A SRT are W. Djordjevic and C. Agosta - Outlier Evaluation In Revision 0, these air start tanks were declared outliers because they use Cinch type leaded anchors which are not covered by the GIP.
External analysis 95C2873-C-003 evaluates the anchorage using data developed by Westinghouse Savannah River (referenced in calculation) and shows a HCLPF PGA equal to 0.55g.
)au Subsequently, bolt tightness checking was conducted on~accessible Cinch anchor installations with only~
failurgto hold tightness.
Since this failure rate is Iess4haa.1%
and the HCLPF is equivalent to about a 1% failure rate, no reduction factor is applied to Cinch anchors.
Therefore, this equipment is found acceptable forAQ6 design basis purposes and the outlier is resolved.
The HCLPF remains at 0.55g PGA.
