8. Are overhead equipment, distribution systems, ceiling tiles and lighting, YZ NEI UE] N/AO and masonry block walls not likely to collapse onto the equipment?

Floresentbulbs overhead are unsecured and could fall out of the light fixture. Hardtarget cabinet will protect internalsfrom damage. Judged acceptable. CR IP2-2012-06120tracks installation of wires to tie florescent bulb to fixture for good seismic housekeeping.

Masonry block wall is seismically qualified by Computech Report no.

R547.01 as discussed in SQUG SEWS.

9. Do attached lines have adequate flexibility to avoid damage? YE NEI U[-] N/A[l Yes attachedlines have adequate flexibility to avoid damage.

10. Based on the above seismic interaction evaluations, is equipment free YE NE: UE1 of potentially adverse seismic interaction effects?

The side synch panel is free to swing on hinge into 21EDG control panel. Restraint bracket on bottom of side panel is broken. Operationspersonnel reattachedand repairedrestraintbracket immediately in our presence. CR IP2-2012-6207 issued for trackingpurposes.

Swing of the side synch panel will be limited because the two nuts will act as a restraint.

8. Are overhead equipment, distribution systems, ceiling tiles and lighting, YE NEI uEr N/AE]

and masonry block walls not likely to collapse onto the equipment?

Yes overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls are not likely to collapse onto the equipment.

9. Do attached lines have adequate flexibility to avoid damage? Y[ NEI uE- N/AE Yes attachedlines have adequate flexibility to avoid damage.

10. Based on the above seismic interaction evaluations, is equipment free YN NEIuEl of potentially adverse seismic interaction effects?

Yes based on the above seismic interactionevaluations, the equipment is free of potentially adverse seismic interaction effects.

Slight surface rust was observed at the top panel bolt holes.

RSLTO EOUIN . R;SAU CR Operability Review: No Degraded or Nonconforming Condition exists per EN-OP-104. Based on the below input from civil engineering, the identified conditions do not impact the structural integrity of the steel liner or the containment building.

Therefore the vapor containment system remains operable. No immediate reportability required per IP-SMM-LI-108.

During tours of the VC at the start of 2R21, Operations identified an additional area of liner insulation that is degraded on the 68' elevation of the VC behind column 7. This area has been added to WO 308669.

This condition is not an immediate operability issue as the insulation is not structural and their sole design basis function is to protect the liner from hot liquid due to possible high energy line breaks and provide a vapor barrier against possible flooding of the 46' elevation. The identified insulation degradation is minor and represents a very small percentage of the insulation coverage, and, as a result, the identified degradation will not adversely affect the design function of the steel liner.

Class 18 Equipment Description Instrument Rack 19 Location: Bldg. VC Floor El. 68' Room, Area Condition Two anchor bolts has concrete crack 2" and 3" away from the bolt. The calculation for the anchorage does not take into account of the crack reduction factor. The two bolts need to be re-revaluated for the concrete crack.

3. Linear interaction for combine tension and shear Evaluation Based on the conservative values from Calculation 42100-C-002 T = tension at bolt = 313#

S = shear at bolt = 111#

Interaction = 313/844+111/781 = 0.51 For crack size < 0.02", RCP =0.75 Pall = 844(0.75) = 633#

Accounting for crack, revised interaction ratio = 313/633 + 111/781 0.637 < 1.0. o.k.
