This report presents the design and evaluation criteria used
by NUTECH to address indications in 19 weldments in the
Reactor Recirculation, Shutdown cooling, and Reactor Water
Clean-up systems to receive weld overlay repairs during the
current 1990 outage (D2Rl2)-at Commonwealth Edison's Dresden
Nuclear Power Plant Unit 2. Ultrasonic (UT) examinations of
welds in these systems since 1983 have identified flaws
judged to be intergranular stress corrosion cracking
(IGSCC). The locations of these 19 weldments are shown in
Figures 1. 0-1 through 1. 0-3. ·Appendix A presents
descriptions of the IGSCC flaw indications within these
weldments. Appendix B presents the weld overlay repair·
details to be applied during the current Dresden Unit 2 1990
outage.
The following weldments with overlay repairs from the
Dresden Unit 2 1988 outage are being built-up to "standard"

2.0 REPAIR AHO RESIDUAL STBESS IMPR<>VBlmliT DESCRIPTION
At the end of the 1990 outage, all welds with overlays at Dresden Unit 2 are planned to be Category "E" weldments per the requirements of NUREG-0313 (Reference 1). "Standard", "design", _and "residual stress improvement" weld overlay repairs will be made during this outage by increasing the pipe wall thickness through the deposition of weld metal 360 degrees around and to either side of the existing weld. For the "standard" and "design" overlays, the weld-deposited band provides additional wall thickness· to restore the
original Code safety margin. In all cases where waterbacking is employed, the welding process produces a strong compressive residual stress pattern on the inside portion of the pipe wall (as discussed in the Reference 5 paper), which prevents further crack growth. The deposited weld metal is either Type 308L or Type 309L with controlled delta ferrite content so as to be resistant to the propagation of IGSCC. Design drawings for all the overlays are presented in Appendix B.
The nondestructive examination (NOE) of the weld overlay repairs to be applied during the Dresden Unit 2 1990 outage
consists of the following:
1. Surface examination by the liquid-penetrant testing · (PT) technique in accordance with ASME section XI of
either the existing pipe surf ace or a "throw-away" first layer • A "throw-away" first layer may be used
for weldments with such extensive surface indications
that ALARA (As LOW As Reasonably Achievable) radiation exposure concerns are not best served by individual welding repairs.

2. Delta ferrite content measurement of the first layer

3. Visual examination of the first weld overlay layer used
as part of the overlay design thickness for evidence of
IGSCC flaws using enhanced acceptance criteria (no
discoloration, porosity, linear indications, etc.).
4. Surface examination of the completed weld overlay by
the PT technique in accordance with ASME section XI.
5. Volumetric examination of· the completed weld overlay
. repair and part of the original pipe wall by the
ultrasonic testing (UT) technique developed by EPRI.
All UT examinations will be performed by EPRI-qualif ied
examiners.

3 • 0 BVALIJATIQlf CRITERIA
Eighteen Reactor Recirculation, Shutdown Cooling, and Reactor Water Clean-up system weld overlay repairs to be applied during the Dresden Unit 2 1990 outage were designed to meet the requirements of "standard" and "design" overlay repairs as defined in NUREG~0313, Revision 2 (Reference 1). In addition, a ·"residual stress improvement" weld overlay repair will be applied to a weldment with "'minor" flaw
indications as defined by NUREG-0313.
3 • 1 Weld Qyerlay Bepaired wel<iments
The following criteria were used by NUTECH to design the "standard" and "design" weld overlay repairs presented in Appendix A:
1. For welds with circumferential flaws, the circumferential flaw profile was assumed to have a depth equal to the greater of 100% of the original pipe wall thickness or the depth associated with the smallest
remaining ligament over a conservative 360 degree length.
2. For welds with axial flaws, the axial flaw depth was
. assumed to be 100% of the original pipe wall thickness with a length equal to the greater of 1.5 times the
pipe wall thickness or its measured length. If an axial flaw was drawn up into an existing overlay due· to
a steam blow-out, the actual flaw depth was used.
3. credit will be taken for the first layer if its delta
XCE-53-101 Revision o
ferrite content is at least 7.5 FN. If the ferrite
content is below this value, any circumferential or axial flaws will be assumed to extend through the first

layer in NUTECH's post-outage as-built reconciliation evaluation.
A bounding under-the-overlay fatigue crack growth of 0.005 inch was used in the overlay design. This was established based on analysis performed by NUTECH in References 6 through - 8 using a conservative crack growth correlation derived from data presented in Reference 9.
5. For circumferential flaws, the weld overlay repair
strength for a combination of dead weight, internal pressure, and seismic stresses was compared to the net section plastic collapse criteria of ASME Section XI,
Table IWB-3641-1 (Reference 10). Because this table has an arbitrary cut-off point at a stress ratio of 0.6, NUTECH has developed an expanded version (Table 3.0-1) based upon the Table IWB-3641-1 source equations shown in Figure 3.0-1.
6. For axial flaws, the weld overlay repair was compared
to "leak .barrier" weld overlay repair criteria presented in Table 3.0-2 from NUTECH Document COM-76-
001 (Reference 11).
Except for weld overlay repairs that tie into pumps, valves, or other components with large surface transitions, the
standard axial length from the center line of the original butt weld to the shoulder of a weld overlay repair is
approximately equal to the square root of the original pipe wall thickness times the mean pipe radius (see Figure 3.0-2;
this simple rule-of-thumb for acceptable weld overlay repair length has been demonstrated both analytically and
experimentally by NUTECH and others).

• 3.2 Unrepaired Flawed. Weldllents
Weld No. PS2A/202-1B has three widely spaced flaw
indications with a maximum through-wall depth of 20% and
maximum circumferential length of · 3. 5". Because these
indications fall within the "minor" cracking size envelope ·
recommended by Section 4.5 of NUREG-0313 for stress
improvement mitigation, this weldment will receive a two
layer "residual stress improvement" weld overlay repair
during the current Dresden Unit 2 outage. As part of
NUTECH's post-outage as-built reconciliation, a final flawed
pipe evaluation will be performed for this weldment that
will include the affect of actual weld overlay repair axial
shrinkages on the sustained stress state of this weldment.
