1) "Stress Intensity factors for Part-through Surface cracks"; NASA TM-I 1707; July 1992.
2) Crack Growth of Alloy 600 Base Metal in PWR Environments; EPRI MRP Report MRP 55 Rev. 1, 2002 Arkansas Nuclear One Unit 2 Component: Reactor Vessel CEDM -"49" Degree Nozzle, Downhill Azimuth, Augmented Analysis 1.043" above Nozzle Bottom Calculation Basis: MRP 75 th Percentile and Flaw Face Pressurized Mean Radius -to-Thickness Ratio:- "Rm/t" -- between 1.0 and 300.0 Note: Used the Metric form of the equation from EPRI MRP 55-Rev. 1.

The correction is applied in the determination of the crack extension to obtain the value in inch/hr.

OD Surface Flaw The first Required input is a location for a point on the tube elevation to define the point of interest (e.g.

The top of the Blind Zone, or bottom of fillet weld etc.). This reference point is necessar to evaluate the stress distribution on the flow both for the initial flaw and for a growing flaw.

This is defined as the reference point. Enter a number (inch) that represnets the reference point elevation measured upward from the nozzle end.

RefPoint := 1.043 This allows a 0.25 inch freespan below bottom of weld To place the flaw with repsect to the reference point, the flaw tips and center can be located as follows:

1) The Upper "T-tip" located at the reference point (Enter 1)
2) The Center of the flow at the reference point (Enter 2)
3) The lower "C-tip " located at the reference point (Enter 3).

Val := 2 Upper Limit to be selected for stress distribution (e.g. Weld bottom).

This is the ekvation from Nozzle Bottom. Enter this value below ULStrs.Dist := 1.293 Upper Axial Extent for Stress Distribution to be used in the Analysis (Axial distance above nozzle bottom)

BZ:= 1.043 Location of Blind Zone above nozzle bottom (inch)

This allows a 0 25 inch freespan below bottom of weld The Second Input is the Upper Limit for the evaluation, which is the bottom of the fillet weld leg.

This is shown on the Excel spread sheet as weld bottom. Enter this dimension (measured from nozzle bottom) below.

The correction is applied in the determination of the crack extension to obtain the value in inch/hr.

OD Surface Flaw The first Required input is a location for a point on the tube elevation to define the point of interest (e g.

The top of the Blind Zone, or bottom of fillet weld etc.). This reference point is necessar to evaluate the stress distribution on the flow both for the initial flaw and for a growing flaw. This is defined as the reference point. Enter a number (inch) that represnets the reference point elevation measured upward from the nozzle end.

RefPoint :=l1.544 Normal blind zone To place the flow with repsect to the reference point, the flow tips and center can be located as follows:

1) The Upper "C-tip" located at the reference point (Enter 1)
2) The Center of the flaw at the reference point (Enter 2)
3) The lower "C-tip" located at the reference point (Enter 3).

Val := 2 Upper Limit to be selected for stress distribution (e.g. Weld bottom ).

This is the elevation from Nozzle Bottom. Enter this value below ULStrs.Dist := 1.8317 Upper Axial Extent for Stress Distribution to be used in the Analysis (Axial distance above nozzle bottom)

The correction is applied in the determination of the crack extension to obtain the value in inch/1hr.

Through Wall Axial Flaw The first Input is to locate the Reference line (eg. top of the Blind Zone).

The throughwall flaw "Upper Tip" is located at the Reference Line.

Enter the elevation of the Reference Line (eg. Blind Zone) above the nozzle bottom in inches.

BZ:= 1.25 Location of Blind Zone above nozzle bottom (inch)

Note :- BZ lowered; This increases the freespan length to 0.536 inch The Second Input is the Upper Limit for the evaluation, which is the bottom of the fillet weld leg.

This is shown on the Excel spread sheet as weld bottom. Enter this dimension (measured from nozzle bottom) below ULStrs.Di,,t := 1.786 Upper axial Extent for Stress Distribution to be used in the analysis (Axial distance above nozzle bottom)

The correction is applied in the determination of the crack extension to obtain the value in inch/hr.

OD Surface Flaw The first Required input is a location for a point on the tube elevation to define the point of interest (e.g.

The top of the Blind Zone, or bottom of fillet weld etc.). This reference point is necessar to evaluate the stress distribution on the flow both for the initial flow and for a growing flaw This is defined as the reference point. Enter a number (inch) that represnets the reference point elevation measured upward from the nozzle end.

RefPoint 13 This is the reduced Blind zone for augmented analysis; permits a 0.2504 inch free span & 0.09 inch Propogation Length To place the flaw with repsect to the reference point, the flaw tips and center can be located as follows:

1) The Upper "c-tip" located at the reference point (Enter 1)
2) The Center of the flaw at the reference point (Enter 2)
3) The lower "c-tip" located at the reference point (Enter 3).

Val := 2 Upper Limit to be selected for stress distribution (e.g. Weld bottom ).

This is the elevation from Nozzle Bottom. Enter this value below ULLStrs.Dist := 1.5504 Upper Axial Extent for Stress Distribution to be used in the Analysis (Axial distance above nozzle bottom)

S. Brihmadesom Verified by: B. C. Gray Refrences:

1) "Stress Intensity factors for Part-through Surface cracks"; NASA TM-11707; July 1992.
2) Crack Growth of Alloy 600 Base Metal in PWR Environments; EPRI MRP Report MRP 55 Rev. 1, 2002 Arkansas Nuclear One Unit 2 Component: Reactor Vessel CEDM -'49" Degree Nozzle, 45 degree from Downhill Azimuth, Augmented Analysis; 1.544" above Nozzle Bottom Calculation Basis: MRP 75 th Percentile and Flaw Face Pressurized Mean Radius -to-Thickness Ratio:- "Rmdt" -- between 1.0 and 300.0 Note: Used the Metric form of the equation from EPRI MRP 55-Rev. 1.

The correction is applied in the determination of the crack extension to obtain the value in inch/hr.

OD Surface Flaw The first Required input is a location for a point on the tube elevation to define the point of interest (e.g.

The top of the Blind Zone, or bottom of fillet weld etc.). This reference point is necessar to evaluate the stress distribution on the flow both for the initial flaw and for a growing flaw.

This is defined as the reference point. Enter a number (inch) that represnets the reference point elevation measured upward from the nozzk end.

RefPoint := 1.544 This is the as-biult Blind Zone To place the flaw with repsect to the reference point, the flaw tips and center can be located as follows:

1) The Upper IC-ti;p" located at the reference point (Enter 1)
2) The Center of the flaw at the reference point (Enter 2)
3) The lower "C-tip" located at the reference point (Enter 3).

Val := 2 Upper Limit to be selected for stress distribution (e.g. Weld bottom ).

This is the elevation from Nozzle Bottom. Enter this value below ULStrs.Dist := 2.1632 Upper Axial Extent for Stress Distribution to be used in the Analysis (Axial distance above nozzle bottom)

1) "Stress Intensity factors for Part-through Surface cracks"; NASA TM-i 1707; July 1992.

The correction is applied in the determination of the crack extension to obtain the value in inch/hr.

OD Surface Flaw The first Required input is a location for a point on the tube elevation to define the point of interest (e.g.

The top of the Blind Zone, or bottom of fillet weld etc.). This reference point is necessar to evaluate the stress distribution on the flaw both for the initial flaw and for a growing flow. This is defined as the reference point. Enter a number (inch) that represnets the referene point elevation measured upward from the nobzle end.

Refpoint = 1.25 This is the reduced blind zone; providing a propagation length of 0.386 inch; freespan length is 0.546 inch To place the flaw with repsect to the reference point, the flaw tips and center can be located as follows:

1) The Upper "e-tip" located at the reference point (Enter 1)
2) The Center of the flow at the reference point (Enter 2)
3) The lower "C-tip" located at the reference point (Enter 3).

Val := 2 U'pper Limit to be selected for stress distribution (e.g. Weld bottom ).

This is the elevation from Nozzle Bottom. Enter this value below ULStrs.Dist := 1.796 Upper Axial Extent for Stress Distribution to be used in the Analysis (Axial distance above nozzle bottom)
