1.0 INTRODUCTION
A leak leading to the shutdown of Consumer Power Company's Palisades
Nuclear Plant was identified in a check valve (CK-ES3166) in the auxiliary
building west engineering safeguards room on February 17,1994.
Subsequent nondestructive examinations also identified indications in
another check valve (CK-ES3181) and additional indications in valve
CK-ES3166. As shown in the Reference 1 system diagram, these valves
are part of the Engineering Safeguard System (ESS ; Safety injection,
Containment Spray, and Shutdown Cooling Systems). The general
location of these valves is shown in Figure 1.0-1. The identified
indications are located in the downstream end of the check valves which
are each welded to a 24" x 24" x 14" tee fitting.
The ESS was originally constructed in accordance with ASA B31.1-1955.
For the purposes of inservice inspection (ISI), the ESS is currently treated
as an ASME Class 2 system. This calculation package presents the design
of Code-approved weld overlay repairs for these check valves.

2.0 MATERIALS
The Reference 2 stress isometric drawings indicate that check valves
CK-ES3166 and CK-ES3181 are in a 24" piping system with an HC-3
designation. Per the Reference 3,4, and 5 piping class sheets, an HC
system has an ANSI B16.5 rating of 150# and is made of austenitic
stainless steel.
The Reference 6 and 7 spool drawings indicate that the tees welded to the
check valves are ASTM A-358, Class 1, Type 304. The Reference 8
procurement documentation indicates that the bodies of check valves CK-
ES3166 and CK-ES3181 are ASTM A-351, CF8M.

3.0 DESCRIPTION OF INDICATIONS
The Reference 9 and 10 documents present background information
detailing the discovery and investigation of the check valve indications.
Replication and etching of these valves indicate multiple weld repairs prior
to operation of the Palisades Nuclear Plant. One large repair was found
adjacent to the through-wallleak.
Appendices A and B contain indication location sketches for the check
valves based upon visual (VT), ultrasonic (UT), liquid penetrant (PT), and
radiographic (RT) examinations. Indication 8 shown in Appendix A for
valve CK-ES3166 is the flaw found leaking on February 17. Because of
their location in the cast valve body transition areas adjacent to the valve-
to-tee weldments, volumetric UT was unable to determine the depth and'
through-wall position of the indications.

The weld overlay repairs to be applied to check valves CK-ES3166 and
CK-ES3181 shall meet the requirements of American Society'of-
Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC)
Case N-So4-1 (Reference 11) and Paragraph IWB-3640 of ASME BPVC
Section XI,1983 Edition with Winter 1985 Addenda or later Editions and.
Addenda. The weld overlay repair designs presented in this calculation
package shall use the Reference 12 Edition / Addenda of Section XI. |1
|The outside circumference, L ,, of a 24" nominal outside diameter pipe is
as follows:.)~l
L , = 24" * rr = 75.4" .)
The total length of the circumferentialindications shown in Appendix A'for
check valve CK-ES3166 is clearly greater than 10% of L,.. Therefore, the
design of the weld overlay repair for valve CK-ES3166 shall be based upon
an assumed 100% through-wall by-360* long flaw. Consequently,
because the weld overlay repair to be applied to valve CK-ES3166 shall be
made using the Gas-Tungsten Arc Welding (GTAW) technique, ASME
BPVC Section XI Tables IWB 3641-1 and IWB 3641-2 shall be utilized
(Table IWB-3641-1 usually governs).!
The total length of the circumferentialindications shown in Appendix B for
check valve CK-ES3181 is clearly less than 10% of L, . Therefore, as;
permitted by Code Case N-504-1, the design of the weld overlay repair for

V/.

valve CK-ES3181 could be based upon an assumed 100% through-wall-by-,
|
actual total length flaw. However, due to the small magnitude of loads'
acting at valve CK-ES3181, the design criteria employed for valve
CK-ES3166 provides the thinner weld overlay repair while still meeting the
requirements of Code Case N-504-1 and Section XI without introducing
unnecessary additional weld overlay axial shrinkage. Therefore, the weld
overlay repair design for valve CK ES3181 shall also be based upon an
assumed 100% through-wall-by-360* fong flaw.
Table 4.0-1 presents Table IWB-3641-1 from ASME BPVC Section XI
(Reference 12). Because this table has an arbitrary cut-off point at a
stress ratio of 0.6, VECTRA has developed an expanded version of Table |
IWB-3641-1 as shown in Table 4.0-2 that has been previously presented
to the United States Nuclear Regulatory Commission. The expansion of
this table is based upon the source equations presented in Figure 4.0-1.

5.0 LOADS / STRESSES
The design criteria described in Section 4.0 requires that the following
primary axial (P ) and bending (P ) load / stress combination be determinedm e
for check valves CK-ES3166 and CK-ES3181:
P + Pe = P + N + WM or %E)m

Table 5.0-1 presents axial forces and moments provided in the
Reference 15 design information transmittal.
As discussed in Section 2.0, the check valves are in a piping system with
an HC-3 designation. Per the Reference 16 piping class summary, an HC-3
system has a design internal pressure (P,) of 60 psig.
Per the Reference 17 and 18 thickness measurement reports, the valve
side of the CK-ES3166 check valve-to-tee weld has an average as-built
thickness (T ae) of 0.61" and the valve side of the CK-ES3181 check3
valve-to-tee weld has an average as-built thickness (T ,,) of 0.58". Both3i
check valve-to-tee weldments have a nominal diameter (OD) of 24".

6.0 WELD OVERLAY DESIGN METHODS AND RESULTS
6.1 Overlav Thicknen
To utilize ASME BPVC Section XI Paragraph IWB-3640, the allowable
design stress intensity, S , must be determined in accordance with ASMEm
BPVC Section lli (Reference 19). As discussed in Section 2.0, the bodies
of check valves CK-ES3166 and CK-ES3181 are ASTM A-351, CF8M and
the tee fittings welded to these valves are ASTM A-358, Class 1,
Type 304.
Also as discussed in Section 2.0, the check valves are in a piping system
with an HC-3 designation. Per the Reference 13 piping class summary, an
HC-3 system has a design temperature of 300*F.
Therefore, the following S values are provided in ASME BPVC Section illm
for the check valves and tees at 300"F:

Therefore, taking the highest normal operating condition primary stress1
combination * (P + P, = 3,353 psi' *) provided in table 5.0-3 and 11
dividing it by the lowest design stress intensity value presented above (S.
= 16,600 psi) provides a stress ratio (SR) less than the lowest stress ratio I1
presented in Table 4.0-2 ((P. + P ) / S = 0.20 < 0.36). Therefore, per |3
Table 4.0-2, the maximum allowable flaw depth (a)-to-thickness (t) ratio is:
a/t = 0.75
a = 100% x T
T = per Section 5.0
t = combined pipe wall + overlay thickness |
= T + t,|
t, = weld overlay thickness|
|
Therefore: T / (T + t ) = 0.75o
and: t, = T / 3||
|For check valve CK-ES3166: t, = 0.61" / 3 = 0.20"
For check valve CK-ES3181: t, = 0.58" / 3 = 0.19"
|
|6.2 Overlav Axial Lonath
Code Case N-504-1 suggests an overlay axial length, Lwon., beyond each
end of any observed flaws as follows:
For load combinations involving SSE to control the design of the weld overlay*
repair, these load combinations must have a magnitude greater than 2 timesload combinations involving OBE.

where, prior to overlay application:
R = outer pipe radius

T = per Section 5.0
For check valve CK-ES3166: Lwon. = 2.0" ,
For check. valve CK-ES3181: L on- 2.0"w
The indication location sketches in Appendices A and B show that the!
check valve-to-tee butt welds are 0.85" wide and that indications extend |
as far as 2.2" (valve CK-ES3166) and 2" (valve CK-ES3181) into thei
valves from the edge of the. butt welds. Therefore, per Code Case
N-504-1, the axiallengths of the weld overlay repairs, Lwon~, measured'
from the center of the butt welds onto the valve bodies should be:
For valve CK-ES3166: Lwon.. = Lwon. + (0.85" / 2) + 2.2"l
= 4.6" !
For valve CK-ES3181: Lwon- = Lwon. + (0.85" / 2) + 2"= 4.4" i
Because no indications have been observed on the tee-side of these
weldments, the weld overlay repairs will only be extended onto the tees
per the Code Case N-504-1 suggested length from the centerline of the
butt welds.

7.0 SUMMARY AND CONCLUSIONS
This calculation package presents the design of weld overlay repairs for
containment sump check valve-to-tee we!dments at the Palisades Nuclear
Plant. These weldments are on the downstream side of check valves
CK-ES3166 and CK-ES3181 and contain indications attributed to IGC
caused by original construction, repair, and reinstallation welding heat
input sensitization as verified by metallurgical examinations.
The weld overlay repair designs presented in this calculation package are
based upon the requirements of ASME BPVC Case N-504-1 and
Section XI, Paragraph IWB-3640. Because of the small applied mechanical
and design internal pressure stresses at these weldments, the weld overlay
repair design thicknesses are the minimum 1/3 of the average as-built pipe
wall thickness prior to overlay application as defined by IWB-3640. Due to
the location of the indications in the check valve bedies as shown in
Appendices A and B, the weld overlay repairs shall extend axially a
minimum 0.75 V'(R T) distance beyond the end of the observed indications
on the valve bodies and 0.75 V(R T) from the centerline of the valve-to-tee
butt weld onto the tee.
