The purpose of this calculation is to determine maximum allowableflaws in various WBN Refueling Water Storage Tank Vortex nozzleaustenitic shielded metal arc welds (SMAW). This evaluationutilizes conservative fracture mechanics analyses to determinethe critical flaw size of the welds.

2.0 Assumptions

This analysis utilizes the procedures contained in ASM1E SectionXI paragraph IWB-3640. Code Case N-436, and Appendix C. All ofth welis considerei are SMAW joining 304 stainless steel basematerial using E3083-16 filler, and therefore, it is assumed thata limit lcad analysis is .appropriate since austenitic stainlesssteel will plastically collapse be~fore the onset of snab1 eductile tearing. Thermal and bending stresses are cinsidered tobe zerD since concrete and ;rout will not allow bending of-~thestainless steel.

o Option A, Allowable Flaw Size Evaluation of-the Codesand Standards Evaluation Module.

0 Option J, Circumferential Crack Using the SourceEquations of the Allowable Flaw Evaluation Module.

The source equations in the pc-CRACK program are identical tothose contained in ASME Code Case N-436 and EPRI-4690-SR. Therelevant dimensions used in this computation are:

a z crack depth, 1 crack length

Streses nd afeny facotrs w4ere~ c'alculated as fo~llows.

Normal Answr

The longitudinal membrane stress was calculated to be half of the

hoop stress (581.75 psi).

Since the welds are SMAW. the inputs to the source equations werealtered to account for the load multiplier, Z. Since the sourceequation option of pc-CRACK ices not provide prompts for input ofZ; the safety factor was adjusted to produce results inaccordance with IWB-3640.

FS =2.77 x Z = 4.01, Z =1.15P1 + 0.013(OD - 4)] 1.449

There are two major resultS of this calculation.

1) The vortex nozzle can withstand a longitudinal through-wall'crack up to 48.9 inches and still meet the ASME safey margins.

2) The vortex nozz-le-to-pipe girth weld can withstand a through-wall crack up to 70% of circumference and still meet the ASMEsafety margins.
