t 1.0 ULTRASONIC EXAMINATIOh CRITERIA 1.1' Scope Vermont Yankee intends to include 46 welds of the Recirculation and Residual Heat Removal Systems in the initial sample selected for examination during the 1984 refueling outage. The sample size has been determined based upon the following table: Available. Percent in Number of Resultant Condition populaticn Initial Sample Examin4tions Overlays of repaired welds with IGSCC greater than or equal to 10% of circumference 17 70* 12 Unrepaired welds with known IGSCC 12 100 12 Previously inspected welds with no indication of 26 20 7 IGSCC Previously uninspected welds 60 20 16 Repaired welds with IGSCC less than 10% of the 5 0 0 circumference Total 47 4 'Further distribution of'the sample set will include assurance that the different pipe sizes are represented in the sample. If additional IGSCC is detected in the samples representing the welds not previously inspected or the previously inspected welds-not found to contain IGSCC, the sample size will IMt increased in accordance with the rules of IWB 2430'of Section II as defined in I&E Bulletin 83-02.

  • Ten overlayed joints are identical (sweepolet to riser). The overlay thickness is greater ~than 75% Tmin at each joint, greatly exceeding well thickness required for design loads. The inspection approach here is to UT'fivg of these joints (most

.affected by ICSCC) for weld metal integrity:and bond to base-metal. If no indications are found. the remaining:five will not be re-inspected. ~ al_

1.2 personnel All examination personnel shall be qualified to basic levels, I, II, and III of SNT-TC-1A as applicable. Additionally, all examination personnel will be demonstrated to be qualified to a level of competence commensurate with their functions. Examiners involved in equipment setup or scanning operations will be trained and demonstrated proficient to assure both their technical ability and their ability to perform activities consistent with the rules { of ALARA, i l-The process for qualification of all personnel who will perform evaluations, either of manual examinations or examinations i, utilizing. advanced data acquisition and processing shall be that process presently in effect.at the EPRI NDE Center. l - Limited numbers of personnel are qualified through the NDE Center for all systems, methods, and techniques currently under l consideration. Additional personnel, if required,-shall receive i the same level of qualification and examination. Due to the complexity of the equipment, methods, and techniques involved no plant-specific training and qualifications i requirements have been developed. When decisions as to exactly what equipment will be used are made, a program will be i established to assure proper training of those individuals involved in the examinations. 4 I 1.3 Equipment A number of vendors and their equipment are being reviewed for F their abilities with regard to detection, discrimination, and i sizing. No decision has been made with respect to the equipment [ to be used in order that Vermont Yankee may take full advantage of l developments in this technology. ] Three separate systems for automatic and semi-automatic data acquisition, storage, and display are presently under consideration. Each of'these systems is presently undergoing l extensive evaluatior.. Automated and semi-automated scanning employing the Ultra Image III system as developed by General Dynamics and utilized by [ General Electric Company is being reviewed. -This system, as demonstrated,Lre11es heavily on spatial information for l discrimination of IGSCC. A-scan signals are displayed in order that signal characteristic evaluation can be employed in } discriminating IGSCC reflectors from geometric reflectors.-"This i cystem is being evaluated considering this limitation and an effort to provide additional information with regard to other paremeters of the ultrasonic signal may be obtained-by selective utilization of the ALN'4060. l Vermont Yankee plant-specific considerations for employing the AMAps automatic scanner now being utilized with Ultra I. mage III' J , 4 ~...

are being considered. Overall clearances, interferences, and weld crown position and conditions will be reviewed. The P-scan System as deployed by ITL is being investigated. As with Ultra Image III, this system relies heavily on spatial information for IGSCC identification. Additional investigative utilization of the ALN 4060 is again.being considered. Scanners, both automatic and semi-automatic for use with P-scan are being reviewed. The UDRPS as utilized by NES of Danbury, Connecticut is being reviewed as another possible tool for IGSCC detection and discrimination. This unit also applies spatial analysis to ICSCC discrimination. UDRPS utilizes enhanced signal processing to reduce the effects of grain boundary noise. As with Ultra Image III and P-scan some signal discrimination capability is being considered through use of ALE 4060 for those indications Which cannot be discriminated on spatial and A-scan characteristics alone. J At this time UDRPS utilizes the AMAPS scanner and is only i functional in an automatic mode. Utilization of the AMAPS scanner is already being considered. Manual examinations are at this time being considered for those welds or portions of welds not accessible to AMAPS. Qualified manual techniques as utilized for' detection and discrimination during the spring 1983 refueling outage will be available to supplement other examination methods. Key to this evaluation process is the considerations of man-rem economization. Certain systems appear efficient in that initial stay times are short, however repeated entries reduce this -apparent economy. Systems which are capable of gathering,- storing, and manipulating all available data are seen as having the advantage over those which need repeated "on pipe" evaluation. Review of these systems is ongoing with full consideration as to their advantages and'1 imitations. The results of the EPRI NDE Center _ qualifications as well as their in-process or upcoming-field performance'are.also under scrutiny. Final decision on the equipment is being reserved until all available data from the individual qualification and initial field applications can be reviewed. 1.4-.Sizina Vermont Yankee is investigating available techniques for' sizing-IGSCC flaws including ID and OD creeping wave methods and crack tip diffraction. These techniques are being investigated as applicable to the advanced ultrasonic' equipment under consideration as well as their more conventional applications included in the EPRI flaw-sizing. seminar. Flaw-sizing' techniques-at Vermont Yankee will be qualified prior'to application. - -.. ~ ~ ~

1.5 Overlay Inspection Existing weld overlays in our inspection program, as well as any necessary new overlays, will be inspected to verify the integrity of both the weld inetal and its bond to the pipe base material, in a manner consistent with ASME Code, Section V Paragraph T550, 1 4 I l 1 l l _4_-

l 2.0 CRITERIA FOR FLAW EVALUATION 1 L i 2.1 Flaws detected by non-destructive examination will be evaluated to l the rules of ASME Code Section II Article IWB-3600, supplemented by NRC SECY 83-267C, Paragraph C.2. Allowable flaw depth and length at end of fuel cycle will be limited to two-thirds (2/3) of the IWB-3640 allowable. Flawed joints which meet this criteria considering upper bound IGSCC and fatigue crack growth will be considered adequate for one operating cycle. (Approximately 12-13 months.) ) 2.2 Exceptions to Paragraph 2.1 are flaws where detected length exceeds 30% of the pipe diameter. These indications will be weld overlay repaired regardless of "UT called" depth unless the - ultrasonic inspection technique is capable of very accurate sizing i and has been so qualified. If depth measurement for a greater than 30% long flaw is utilized in a flaw evaluation, the specific UT technique and qualification will be submitted for staff review. 2.3 A Tearing Instability analysis in accordance with criteria specified in NUREC/CR-3464 and EPRI NP-2261 will also be performed. This elastic-plastic fracture mechanics analysis will demonstrate that the flawed system will not fail assuming large cracks and' loads in excess of design loads. Lower bound material properties will be utilized in this analysis. l.

a 3.0 CRITERIA FOR FUTURE WELD OVERLAY RgpAIR 3.1 Where flawed joints are repaired by weld overlay, the thickness of the overlay will be sufficient to provide full IWB-3640 margin during the next operating cycle. Flaws will be assumed to grow through the original pipe wall over the detected length. The advantageous effect of the compressive stress induced by the overlay process will not be considered in sizing the overlays. ~ 3.2 Multiple short cracks will be treated as one crack with length equal to the sum of the circumferential lengths for both flaw evaluation and overlay design if applicable. 3.3 An outage report will be submitted to the-NRC staff for review. This report will contain: a. Ultrar:onic Inspection Techniques and Qualifications, 1 b. Joints examined and results, c. Flaw evaluations if required, including re-evaluation of unrepaired flaws, and d. Weld overlay repair design and analyses techniques if required. 't - -

\\ 4.0 OPERATION FOR A SECOND CYCLE OF OPERATION WITH WELD OVERLAYS 1 1 ^ 4.1 Current Status o Twenty-two weld overlays on 12-inch diameter pipe were applied at the 1983 refueling outags, o These are structural overlays with a typical thickness of (0.5) (TMIN). Overlays are generally 0.25 to 0.45 inches. l Overlay data sheets are included in Enclosure II, 4.2 Desian Criteria and Inspection 4.2.1 These overlays satisfy the' criteria of ASME Code, Section III, Subsection NB and Section XI, Article IWB 3640. The design analysis included secondary stress and fatigue evaluation for a period of about five years. This 0 includes 25 startup-shutdown cycles (100 F/hr) and 25 0 emergency cycles (456 F/hr). In the current operating period, only 4 startup cycles and no emergencies.have occurred. Thus, cyclic loading on the recirculation system is minimal and if the current excellent plant operation continues, structural integrity of the overlays is assured for well in excess of five years. 4.2.2 At the time of installation, the overlays were inspected to verify the integrity of both the weld metal and its bond to the pipe base material, in a manner consistent with ASME Code, Section V, Paragraph T550. No indications were found. 4.3 IGSCC Crack Growth Into A Weld overlay j 4.3.1 Weld Metal l Vermont Yankee specified Type 308L weld metal with carbon-i content less than or equal to 0.03% and delta ferrite ~ Readings of controlled to a level of between 8 and 15 FN. as-deposited weld metal were taken of the first layer Where practical, and the final layer.for each overlay. The initial layer results were all in excess of 8 FN. ~The final layer results were between 12 and 15 FN. Weld metal with these properties provides outstanding l resistance to IGSCC. This has been demonstrated by both

test and theory. 4.3.2 Survey of Types 308 and 308L IGSCC Test Results Pertinent results to illustrate the effects of_ carbon i content and ferrite on weld metal resistance to IGSCC are presented in the following subsections. _y. 1

. =,. i Constant Extension Rate Tests (CERTs) i Test results from CERTs (References 1 and 2) for low carbon Types 308 and 308L are shown in Table 1. The CERT is simi)ar to a tensile test, performed at slow strain rates (constant extension rate) in an aggressive 0 environment (550 F, 8 ppm oxygen water) to force fracture. The fracture is then examined for.IGSCC characteristics. No IGSCC was shown for the Types 308 and 308L tests in Table 1, even for cases where the wcld metal was given a severe furnace sensitizing treatment. Constant Load Tests constant load tensile test results (Reference 3) at 5500F in 0.2 to 100 ppm oxygen content water are shown in Figure 1. Types 308 and 308L were tested, both as-deposited and given furnace sensitizing treatments. Loads are as high as 125% of the yield strength at 0 550 F. No failures resulted for Type 308L specimens, regardless of ferrite content; no failures resulted for Type 308 specimens with % ferrite greater than or equal to 8%. Other constant load tests were also performed (Reference

3) for 308L in chloride environments. Type 30SL weld overlays on Type 304 stainless steel were tested at 125%

of the 750r yield strength in an aqueous environment of 0 100 ppm Cl at 200 F. No cracking or attack was found after test times of 178 and 138 hr., even for a specimen given the sensitizing treatment of 10 hr. at 11500F. Ferrite Effect - Sensitization Immunity In References 1 and 2, the beneficial effects of ferrite content in Types 308 and 308L are discussed with regard to IGSCC susceptibility and sensitization inununity. Whereas, chroutium carbide precipitation occurs intergranularly. during' aging of austenitic Type 308 stainless 9 teel, no such precipitation occurs along austenite-austenite grain boundaries in duplex Type 308 containing suitable amounts and distributions of ferrite. 'Instead, the precipitation j occurs exclusively along austenite-ferrite phase boundaries. Since chromium diffusivity is approximately 1003 times greater in ferrite than in austenite at 1100 F, the 0 chromium for this precipitation is supplied principally from the chromium-rich ferrite phase. A small-zone of -chromium depletion in the austenite is subsequently: replenished by chromium diffusing from the interior of the austenite.' After-this " healing". the material is immune to'intergranular corrosion in ASTil A262 Practice E and-IGSCC in air-saturated water at 5500F., -,.~.-

a Models hava been developed (Refe: ences 1 and 2) based on the above mechanism to describe IGSCC as a function of carbon content and the amount of ferrite-austenite (d-Y) boundary area. The critical distribution of boundary area l for rapid healing is that amount which is sufficient to l ' tie up all of the available carbon as chromium carbide ( exclusively along ferrite-austenite boundaries. Both the amount and distribution of ferrite-austenite boundary area can be expressed as a function of the metallographic M. This is a measure of the number of parameter, NL intercepts a random test line makes with d-Y boundaries Per unit length of test line. Figure 2 shows the model predictions of NL , as functions of %C, to maintain a critical amount of d V boundary area (lino S ) and a critical distribution of y ac-V boundary area (curve Y). The'value of Ng' I for rapid healing is the higher of the two curves. ASTM A262 Practice E results shown in Figure 2 verify the model predictions. At 0.03%C, the maximum of-Type 308L, En - Y = 200 cm-1 is required for rapid healing and immu d nity to intergranular corrosion. At 0.015%C, or less, essen tially no ferrite is required. Figure 3 P ots data from Reference 1 to relate Un -Y d l to volume % ferrite. For as-deposited Type 308L, as in an overlay repair, about 3% ferrite is adequate to achieve B

  • T = 200 cm-1 and intergranular corrosion immunity.

L Even for the solution treated material, 8% ferrite achieves the 200 value. Thus, the whole range of heating possibilities is covered by the Type 308L weld overlay repair requirements of-8% ferrite minimum, and the overlays should be immune to IGSCC. Crack Arrest l l Figure 4 (Reference 4) shows'an IGSCC in Type 304 t essentially arresting at.the base metal / weld interface " annealed" zone. This annealed zone is caused by. temperatures at this location during welding that ace in the solution heat treatment range. Thus, this interface acts as a further protection against the propagation'of-l IGSCC into weld overlay repairs. 4.3.3 g her Information l A large number of General' Electric Co.' pipe tests have l been performed to qualify nuclear' grade Type 316 (less l than or. equal to 0.02%C) for piping replacement'(Reference [ 5). Thesa materials were welded by Type:308L filler-zmetal, which was successfully qualified along with the base metal for resistance to ICSCC. -g_ _a, =

( NUREG-0531 (Reference 6) indicates that Type 301.L with a ferrite content of at least 8% after welding appears to be a good corrosion resistant cladding material on BWR piping inside surfaces for resistance to IGSCC. NUREG-0313, Revision 1 (Reference 7) gives guidance that Type 308L ( with at least 5% ferrite be used to minimize crack susceptibility. As a final point, no field leakage has ever been observed in any BWR welds growing through the weld metal. This includes the higher carbon content Type 308. This demonstrates the weld metal ability to arrest cracks, even though the weld residual stresses are highest at this location in a butt weld. i l l l l

5.0 CONCLUSION

S 1. A large amount of test data shows that Type 308L weld metal is not susceptible to ICSCC. Ferrite contents of 8% or greater provide additional mergin against 10 SCC. o 2. Theoretical predictions support the test data and show that Type 308L with at least 8% ferrite is virtually immune to ICSCC. 3. IGSCC cracks should not propagate into the 303L weld overlays applied at Vermont Yankee. 4. Since the overlays at each weld joint provide structural adequacy, and the overlays are essentially immune to further crack growth, operation for one additienal operating cycle will not reduce Safety Margins below those intended by the ASME Code, Section III. .e'- l ,e "-w9 .\\ .1 n j l l. +, -..y - (. s i. -
