Subject:

Docket No. 50-333 Intergranular Stress Corrosion Cracking Inspection Results for the Reload 7/ Cycle 8 Refuel Outace

References:

1. NRC letter, D. B. Vassallo to J. P. Bayne, dated May 24, 1985, requested inspection plans.

2. NYPA letter, J. C. Brons to D. R. Muller, dated October 28,1986 (JIN-86-49), described the inspection plans for the 1987 refueling outage.

Dear Sirs:

In R2ference 1 the NRC staff requested the Authority's plans for piping inspections and/or modifications to be empleted during the next refueling outage. In Reference 2 the Authority detailed plans for intergranular stress corrosion cracking (IGSOC) inspections to be performed during the 1987 refueling cutage. 'Ihis letter describes the results of these IGSCC inspections.

Although there were sme changes in interpretation of the data during this inspection, no new IGSOC was found on the Recirculation System. 'Ihree indications were found in the core spray "B" locp. A total of 48 welds were inspected including all overlays and cracked welds.

All weld overlays (6 total) installed prior to the 1987 refueling outage, were surface finished to enhance inspectability, and inse~t by personnel qualified in the Electric Power Research Jmu.tute - Boiling Water Reactor Owners Group (EPRI-EHROG) program.

None of the overlays contained indications of IGSCC.

De&a'+% of IGSCC was performed by EBASCO using manual techniques and Independent Testing Imbs (ITL) using autanated P'-acan. All IGSCC indications were sized by two EPRI-qualified inspectors (EBhSCO and General Electric personnel). Pmt to inspection personnel was apprainately 24 person-rem, not including field supervisien and craft support.

Attadiment 1 sununarizes the results of the IGSCC inspection program. 'Ihis attadiment centains the inspection sn= navy, weld overlay information, piping modifications, and cre.ck growth analyses i

performed. details an inspection matrix for the five welds that have been determined to contain IGSCC, and the two welds that have i

been evaluated caneervatively as containing IGSOC. details the weld overlay design information for new overlays. naranas of IGSCC indications found this outage, three additional weld overlays were installed on the core spray "B" loop.

Surface finishing was not performed at this time resulting in a savings of radiatim exposure estimated at 8 pur cn-rem. At the present time, the Authority plans to replace this piping during the 1988 refueling cutage. Attachment 3 details the weld overlay design information.

Attadiment 4 details the crack growth analyses performed on welds with IGSCC indications that have not been repaired by the weld overlay prmaan. 'Ihe welds analyzed are, 28-48, 28-53, 28-56, 12-61, and 28-113. It is noteworthy that no crack growth has been found since induction heating stress inprovement (IHSI) was performed on these welds in 1984. Additionally, welds 12-4 and 28-112 have been analyzed even though the indications in these welds do not exhibit IGSCC-like characteristics.

A total of 27 IGSCC susceptible welds were removed. 'Ihe cost of these piping modifications is over $1.50 million. Radiation exposure to craft labor and mere, A. supervision is apprminately 134 j

person-rem.

'Ihm Authority plans to inplement hytt: ogen water dientistry in the i

Fall of 1987 to further mitigate and prw/ent the occurrence of IGSOC 1

in both piping and vessel w Am.

'Iha Authority also plans to inplement augmented leakage surveillance in accordance with the requirements of Generic Istter 84-11, Attadanent 1.

l.0 Introductim As described in Reference 2, the Authority has inplemented an Ihy 11ar Strees Otzrosiat Cracking (IGSCC) inspection program for stainless steal piping welds at the James A.

FitzPatrick (JAF) Plant. 'R11s program was designed to omform to draft Revision 2 of NUREG-0313 with exceptions as noted in Referanos 2.

Party-two welds were in the original inspection plan as detailed in Referenos 2.

Six welds were to be inspected by the MINAC (hi@t energy radiographic inspection tactinique) process. However, only 2.5 welds were inspected by the MINAC process, and the film was evaluated as ur+--f =hle for int.1.p 0stion per either Section V of the ASME code or EPRI Report NP-3828.

An additimal four NUREG-0313 Chtegory C welds were inspected as a result of a thorou$1 data review of previous IGSOC ir-5++ ion data. Data ihr.^uttien differences were noted on these four Category C and Category E welds that had been inspected in the original weld program. 'the indications had all been noted sinos 1984 and had been inspected previously by at least two impar +<we fram different firms in 1984 or 1985.

All welds in dicit ihr.^41cn differences between the firms were noted based on a past data review were inspected durity the 1987 reftaaling cutage. 'Ihm welds are listed in a matrix format in Attacfiment 2.

'!he inspection results and inspection firms frce 1984 to the present are also identified.

Due to the dotar+1r'n of IGSOC indications in the "B" core spray Piping (Qategory D welds), all Category D weldments were inspected (10 total).

Table 3 provides a summary of all welds (by NUREG-0313 M ww.y) imp-+M during this cutage.

2.0 Pereennel Qualificaticris All personnel were qualified in accordance with the (Electric t

Power Researtis Institute - noiling water Reactar Owners aroqp (EPRI-EMROG) training program. Detection of IGSOC was performed by EBASCO using ammal examinations and Independent Testing Imbs (ITL) using autamated P-ecan.

Sizing of IGSOC indications was perforseed by two independant exuainers, both qualified in sizing in the EPRI-IMROG training program. 'Ihis is in arvvwdanos with NUREG-0313 Rev. 2 (Draft). 'Iha examiners were also fran two irdepi=A.t firms (EBASCO and General Electric).

Wald overlays installed before the 1987 refuelirq outage were surface finished (field criteria of 250 Itei-Flatness of 1/32" I

per incit) to enhance inspectability. All overlays have been re-evaluated to the design requirusents of NUREG-0313 Revision 2 (Draft) " Standard Wald overlays". Inspections were performed by personnel qualified in this asthod by the EPRI-Em0G trainirq program. Althoudt there have been differences in interpretations, the irdin=&ir=1 data has been consistant.

3 Table 1 hi$14d*= the as-built data fztza the overlays after i

surface finishing had been performed. The as-built data is provided in Table 1 to this attachment. Design information is provided in Attachment 4.

Wald overlays (3 total) installed durirq the 1987 refuelirq cutage were designed in accordance with NUREG-0313 Rev. 2 i

(Draft). Two weld overlays were the " standard weld overlay" as defined in NUREG-0313. One weld overlay was the " designed type" as defined in NUREG-0313. This overlay was installed on a weld that had four axial flaus considered to be IGBOC. The as-built data is provided in Table 2 to this attachment. All overlay thickness maa-resents do not include the first dye penetrant tested clear layer.

Surfaos finishirq and inspecticrt of the wald overlays was not performed at this time due to the hi$1 estimated radiation exposure (8 person-ren). The safe and and pipirq has been puri:hemed and is schedaled for replacement daring the 1988 refueling outage. If the core spray pipirq is not replaced

&aring the 1988 refueling cutage, the core sprey weld overlays will be surface finished and inspected. A bonding inspection was performed on these three welds.

4.0 Pipite Modifications Two major pipirq modificaties were cxupleted daring the 1987 refueling cutage. The Reactor Recirculation System bypass lines were removed and capped. This removed 20 IGeoc

===+ih1e welds (NUREG-0313 Category D) frtaa the plant. The cap anterial was 304L and the 304 weld-o-let had a corrosion resistant n1= Mig (308L weld metal with IN greater than 8) installed for IGeoC resistanos. The four cap welds are considered to be category A.

Radiation exposure to field supervisors and craft labor was apprtacinately 46 person-rum to ocuplete this work.

'!he Remishal Heat Removal (14HR) suction pipirq and Reactor Water clearMy suction pipirq were also replaced. 'Ihm stainless steel pipe material was replaced with hi$1 tou$nians

{

na*wwt steel material. 'Ihm type 304 pipe was clad with 308L weld metal (FN p t.s then 8) prior to weldirq to the carbon j

steel pipe. 'Ihis removed seven category D welds. 'Ihm replacement welds are elaamified as Category A.

'Ihm radiation i

emposure to field supervisore and craft labor was e.dmately 88 parean-run to amplete this work. Installation costs of the i

above modificaties were about $1.5 million.

5.0 paia=='+4rws of taald= with Previa = Irdinatirwis Eadt of the unrupaired welds, previously dar1msd cracked, (12-4,28-112, 28-53) were reinspected this cutage.

Additionally, three welds (28-48,28-113, 12-17) that were previcumly called IGSOC in 1984, but were evaluated as not cracked during the 1985 refuel cutage, were re-inspected.

j Althou$1 the data for these indications has been consistant, 1

there have been differences in int-cr.Untion. 'Iherefore, a review of all past IGBOC data shasts (1984 and 1985 cutages) was perfbeend. As a result, four additional Cint.vay C welds were inspected (12-61, 28-56, 28-57,12-81). '!hese welds had been noted by one ir==='+i'=1 firm (EBh800) to have relevant indications dtidt were evaluntad by the agency responsible for discriminatien and sizing (Krattuurk Union-100) as tool marks, l

fusien line indiation ce mot gecaustry. Attachment 2 contains the weld mammary for all welds in Wtich indications determined i

to be IGBOC had been noted durirg this cutage or during past cutages.

{

Walds 12-57,12-81, and 12-17 hema been inspected, and no IGSCC indicatie s were noted. Wald 12-17 is included in the weld mammary (Attachment 2) because indicaties in this weld had been nelled I(BOC in 1984.

Endt of the mespaired welds were inspected by a qualified in-=r+- either mermaally by EBh800, or usirq autcmated M l

by ITL. Any indication was then sized by two qualified i

j innpactcre (EBASOD and General Electric (GE)) for final i

evaluation and discrimination of the indication. A massary of l

the inspection methodology and oceparative results are diarmand below and in Attachment 2.

1 Wald 12-4 EBhSCO first identified this indication (length of 1") in 1984 upon ocupletion of Irukaction Heating Strees Improvement Process (DEI). '!he data was turned over to the JAF Inval III vaxaminer

{

for further waluation, and 100 performed a discrimination and i

sizing assumination in the area of interest. les dotarained the indiention to be IGSOC 1.2" in length with a throu$t% mil dimensim of less then 7.54.

4

7 In 1985 EBh800 again examined the wald, 2 e data showed that the indication had a total length of 2.5"(different amplitude IGing levels fram 1984). EBASCD was unable to size this indi*im ce generate any crack tip signals. his indication was again evaluated by M and datarmined to be IGSOC with a length of 1.9" and depth of 74.

In 1987 this wald was again inspected and the indication noted in the same area at a length of 2".

EBhS00 was unable to size this irdi*im ce detect any crack tips or IGS00-lika responses. Se GE Inval III examinar then re-inspected the wald in the area of interest. Se GE Inval III examiner also noted the indication but was unable to dotaraine depth or IGSOC characteristics.

S e differences in length noted are the result of improved inspection tacimiques and Igg as a result of crack growth.

um1A 12-17 EBhS00 identified an intermittent indication during the 1984 cutage. M then inspected this wald and found it to be IGSOC with a length of 1.6" and a depth of less then 10%.

In 1985 EBh800 inspected this wald, and an intermittent indi+1m was noted, althou$1 it did not exhibit any IGBOC characteristics. M performed a sizing ammaination cut this wald and found the indi*im to be root gecuatry.

In 1987 this wald was re-inspected by ITL using inutcented P-scan. A low level suplitude signal was noted in this area, althou$1 it was not indicative of IGBOC. EBh800 and GE perfonned independent detection and sizing examinations. No throug M all dimension could be obtained, and the signals did not exhibit IGBOC characteristics.

Mald 12-41 ERhSCD and M detected this indicatica during the pre-DEI annuaination portamed in 1984. EBh800 reported a length of 3" during their emaninstion. M evaluated the indication as IGBOC with a length of 0.5" and depth of less then lot through wall.

EBASCO then perfcomed a post-IHSI eaun in 1984 and found the indication to have a len;rth of 5".

M discriminated this area and found this conditica to be counterbore. No through-wall dimension could be determined. Se JAF Imvel III examiner also examined this wald and reported a length of 5", but the signals did not exhibit IGSOC characteristics.

In 1987 EBh800 perfonamd this examination and found an IGSOC ind!*im in an area of sharp counterboro (area noted in 1984) with a length of 0.4" and a depth of less than 10%. Se GE Inval III emmainer confined this indication to be IGBOC having a length of 0.5" and a anwimaq depth of 10%.

r:

Wald 28-112 EBASCD inspected this weld in 1984 ard found an indication with a length of 0.5".

M omifimed this indication as IGSOC with a length of 0.5" and a mawi== depth of 17% through-wall.

In 1985 EBASCO irspected this wald and found IGSOC in the same area with a length of 0.5" (50% to 50% amplitude zwaing levels) and a maw 4== throu$ Mall dimension of 174. M re-inspected this wald for discrimination and sizing and found l

it to be IGBOC with a length of 4.75", and a mawi==

throug M all of 164. Differences in length between 1984 and 1985 are attributed to differencgs in amplitude swding levels (1984-50% to 504/1985-04 to 0%).

In 1987 ERASCO again detected this indication in the mass area. A sizing enemination performed by the EBASCO Isval III examiner revealed this indication to be of root crigin. Also the signal did not exhibit any IGSOC cinaracteristics. The GE Inval III eneminar also examined this weld in the area of interest and oculd not discriminata any IGSOC indications in this area.

Wald 28-48 ERASCO first identified this IGSOC indication in 1984 during a pre-IIEBI emanination as having a length of 1" (50% to 50%

recording level). The indir=+1m was evaluated by the JAF Inval III aumminar and found to have a length of 3.1" (0% to 0%

rwaing level) with a unwimm depth of 18%. M discriminated and sized the indication during a post-IIBI aummination and found it to be IGSOC with a length of 1.2" and a throu$Mell dimension of less than 10%.

In 1985 EBASCO r 6 this weld and found it to have a length of 2.37" (20% to 20% recording level) and a mawi==

depth of 20%. M inspected this weld for discrimination and l

sizing and determined the indi'=+1m to be root geconstry.

In 1987 this weld was inspected by ITL (autcusated h) and l

the indication noted in the some area. mso independent sizing

)

eneminations were parfansed by EBhS00 and GE, and an IGSOC indication was determined to meist in the w as area as noted in 1984. She length was determined to be 1.5" (0% to 0% recording level) with a navi== depth of 204. The differences in sizing length are attributable to differences in amplitude recording levels; there has been no growth of the IGSOC indication since the indication was first identified in 1984.

Wald 28-53 EBASCO first 1&mtified this indication in 1984 as having a length of 1".

Two indiaties were also noted in this name area (total length of 12"), but when plotted it was determined to be root gemstry. M inspected this weld in 1984 with par +iaq=r emphasis in the area of the three indications. M noted cna indicaticrt as IGSOC with a length of 0.5" (50% to 50%

zwding level) and a depth of 0.08".

The other indications were evaluated to ha counterbare.

In 1985 EBhSCO inspected the weld, and the same indications were noted. M perfremad a discrimination and sizing examinaticm and determined the indications to be ID and root gecastry.

In 1987 EBhSCO re-inspected this weld. An IGSOC indication was noted as 10" in length in the seen area as the three previous indications noted in 1984. The throM dimension did not examed 0.1" (Avi=nq of 10%). 3his weld was re-eannined by the GE Isval III examinar and found to be IGSOC with a length of 12" and a depth of 154. ITL also performed a detection examination of this weld after all sizing had been coupleted and noted this IGSOC indication with a length of 12.25".

Since this weld h the requirements of a circumferential flaw of greater then 10% (Reference ICREG-0313, Rev. 2, Draft, Par.

4.5) this weld will be rlammified as a NUREFe0313 Ottagory F weld.

Mald 28-56 EBMKD first identified this indir=+iewt (indication 1) in 1984 as having a length of 0.75".

A =i=ile indication (indication

2) was also noted at a distance of 20" frtan the other i

indiaticri. 1his indication exhibited the sees signal characteristics as indicatics 1.

Due to radiation exposure i

concerns, only indication 2 was evaluated by M.

1his indication was datannined to be of root =--- W.

{

This weld was inspected in 1987 due to the discrepancy noted above. EBASCO detected the IGSOC indication identified in 1984 (1) with a length of 1" and a throu$1-wall dimension of 154.

Indication 2 was not considered a m iable indication. The indiation was also sized by the GE Inval III examiner and found to have a length of 2.5" with a depth of 20%. The change in length is attributable to the difference in amplitude r h aing levels between the 1984 and 1987 examinations.

1 Wald 28-113 i

In 1984 EBASCO k-g+1=d this weld and identified three 1

indicatim s in a pre-IHSI examination. 'Iha weld was turned over to EMU for discrimination and sizing. M performed a post-IHSI examination, and cna indication was considered to be j

IGSCC and was sized at a length of 0.5" and a depth of 10%.

In 1985 EBASCO again inspected this weld, and the same threa i

areas were noted as exhibiting relevant IGSOC-lika indicaticais.

Mari== depth on one indication was 10%. EWU again re-inspected this weld for dianrimination and sizing of the indications. All indications were evaluated as root j

g.c a ar fusion line indications.

1 j

Based on the above dih imhiles, EBASCO re-avamined this weld i

in 1987. '!he above three indicaticals were again detected and i

sized as IGSOC by EBASCO. 'Ihm weld was then avamined by the 2 l

Isval III examiner, 20 concluded that the areas did exhibit IGSOC-lika signal characteristics. Additionally, after all i

sizing was cxmpleted, ITL examined this weld with P-scan t

equigunent. 'Ihey were able to verify two of the three f

indications as IGSoC with apptminately the same length. One indication could not be resolved. Attachment 2 die-the

'Iha Authority has three bi-metallic welds on each RHR loop (six 9

welds total) that contain Inconal 182 weld " butter". Until now l

it was thought these welds cx7.11d not be inspected by ultrasonic

{

methods. It was decided that the welds should be inspected by j

the MINAC method, and a vendor was contracted to perform this i

work. Due to high personnel exposure (3 person-rem total) and j

poor results, only 2.5 welds were inspected.

'Ihm weld histories have been researdied to review the weld i

detail and fabrication records. Calibration blocks will be fabricated to ivnit as-built ocnditions. Ultrasonic s

DESIGN OF WELD OVERLAY REPAIRS FOR CORE SPRAY "B" IDOP JAMES A.

FITZPATRICK NUCLEAR POWER STATION i

i During the inservice inspection of the "B"

core spray loop at i

FitzPatrick as a

part of the 1987 refueling-outage, flaws believed to be due to intergranular strees corrosion cracking j

(IGSCC) were identified at three locations.

The locations and flaw indications are summarized in Table 1-1.

The affected 4

locations are in 10" stainless steel piping with wall thickness of 0.593".

None of the locations had been treated with induction j

heating stress improvement. (IHSI) or similar process.

The applied stresses for each of the locations were taken from Reference l'and are summarized in Table 1-2.

i j

Weld overlay repairs for ther affected~ locations-~were designed' ~ ~ ~ ~ -

based upon the guidance of NUREG-0313 Revision 2 (Draft) [2].

In particular, the repairs for welds 493 and 496, which contain circumferentially oriented f$aws, were designed to meet the requirements of the "standa'rd weld overlay" as defined in i

paragraph 4.4.1 of the NUREG.

In the design process, no credit j

was taken for the remaining unflawed original pipe material.

The j

weld overlay repair for weld 495, which contains only axially l

oriented flaws, was designed as a leakage barrier or " designed weld overlay", as defined in paragraph 4.4.2 of [2].

I Weld overlays were designed in accordance with the criteria of ASME Section XI, Article IWB-3641, 1986 Edition [3].

The primary stresses listed in Table 1-2 (pressure + dead weight + ' seismic) were used.

The allowable stress from ANSI-ASME B31.1 (15.9 ksi) was used in the overlay design process rather than the Section III allowable S, (16.95 ksi), for additional conservatism.

The weld overlay design calculations for welds 493 and 496.were performed using the proprietary computer code pc-CRACK, which automates the Section XI calculations.

The pc-CRACK calculations for these welds are attached, together with design sketches for the repairs.

The design thickness for these welds does not include credit for the first weld layer which is ' acceptable by j

dye penetrant inspection.

The weld overlay repair for weld 495 is not required to restore l

structural adequacy to the weld, since the weld contains only axially oriented flaws.

This repair is required to be two I

welding layers thick, beyond the first surface to pass a dye penetrant examination.

j Weld overlay length is determined for all three repairs by two j

independent factors.

The first of these is that the repair be

]

long enough to provide adequate structural reinforcement of the flawed location.

For this purpose, the minimum full thickness l-3-1

r length of the repair is taken as:

L = 1. 54 Rt = 3. 0" for the purposes of the design.

The second consideration is that the overlay be long enough to allow adequate ultrasonic inspection through the weld overlay.

This will typically require that the overlay be somewhat longer than is required for reinforcement.

The necessary length to support inspection is determined in the field.

ATTACHMENT 4 FLAW INDICATION EVALUATION FOR RECIRCULATION SYSTEM JAMES A.

FITZPATRICK NUCLEAR POWER STATION During the inservice inspection of the recirculation system at Fit 2 Patrick, as a

part of the 1987 refueling

outage, flaw indications were conservatively indentified at seven welds, as shown in Table 4-1.

Stresses from the design stress report are also shown in Table 3-1.

These welds had all previously received IHSI treatment.

The seven welds in Table 4-1 were evaluated for possible IGSCC flaw growth (after IHSI) of the indications, and for flaw acceptance margin in accordance with ASME Section XI, IWB-3640.

The evaluations were done in accordance with NUREG-0313, Rev. 2 procedures, as shown in the Tables 4-1 and 4-2 and the attached pc-CRACK analyses.

Since the flaw indication lengths reported for welds 28-53 and 28-113 are in excess of 10% of the pipe circumference (per NUREG-0313, Rev.

2 guidance), crack growth analyses were also performed for the assumed as-welded condition for thesa LNo welds.

All weld residual stress distributions used in the crack growth analyses are in accordance with NUREG-0313, Rev. 2 and earlier flaw evaluations done for these welds at FitzPatrick (Reports SIR-84-038, Feb.

4, 1985 and SIR-85-015, Rev.

1, May 7, 1985).

A summary of the results of the above flaw evaluations is given in Table 4-2.

It can be seen that no IGSCC crack growth is predicted in any case for the post-IHSI welds.

Furthermore, there is ample margin between the current indication sizes and the section XI allowable flaw sizes, even assuming low toughness SAW welds, and flaws as much as 30% of the pipe circumference in length.

4-1

As mentioned, welds 28-53 and 28-113 were also evaluated for the as-welded case because of flaw lengths in excess of 10% of circumference.

In 40,000 hr.

(about 4.5 yr) these flaws were predicted to grow from 15% and 18% of wall in depth, to 42.8% and 42.6% of wall in depth.

These predicted flaw depths are still below the Section XI allowable flaw depths of 60% of wall, even if the flaw is assumed to be 30% of the pipe circumference in length.

Thus, the above flaw indications in the seven welds are judged acceptable at this time without further repair.
