Dear Mr. Guild:

During the deposition of Mr. Lou DelGeorge, which was taken on November 7, 1985, you requested at several points that information or documentation be provided to you. This letter details responses to your requests as well as enclosing relevant documentation when it exists. At pages 59-60 and again at pages 108-109 of the deposition transcript you requested that NCR's generated at Braidwood concerning problems with the steam generator bolts be provided. As explained by Mr. Michael Miller during the deposition (transcript pages 110-111), all but one of those NCR's had been made available to you. In particular, NCR 332 and 612 were referenced in the Applicant's response to Intervenor's Specific Interrogatory 58 under subcontention item 8.A. NCR 334 was also referenced in Applicant's reponse to Specific Interrogatory 58, under subcontention Item ll.A. One NCR was inadvertently ommitted from the response to Specific Interrogatory 58. That NCR, NCR 649, was provided to you during the deposition. At page 111 of the transcript, you imply that all documents relating to steam generator bolting should be contained on the reference list for subcontention item 1.A. contained in applicant's reponse to Interrogatories 58 and 59. First, your contention raises the issue concerning steam generator bolting in at least seven different subcon-tention items. Applicant cannot be responsible for the fact that you have raised the same issue in different parts of your contention. Secondly, the reference lists for each subcontention item in interrogatory 58 and 59 was never intended to be an exhaustive list of documents which relate 8601220229 860117 ADOCK 0 % y 6 PDR G T)S03

Robert Guild January 17, 1986 Page Two to the issue. The reference list consists of only those documents referenced in Applicant's response. The index provided with Applicant's response to interrogatory 58 and 59 identifies all the documents which relate to those interrogatories. At pages 82-84 of the deposition transcript, you requested the evaluation which led to the slotting of the steam generator bolt holes at Braidwood. Applicant's response to Intervenor's Specific Interrogatory 4 of the Second Set of Interrogatories identifies this document as CECO NCR 413 and it was made available to you at that time. For your convenience, this document is enclosed with this letter as well as the Field Change Request which is referenced in the NCR. At pages 103-105 of the deposition transcript you ask Mr. DelGeorge for a history of the steam generator bolting problems at Braidwood. Mr. DelGeorge stated that in preparation for the Enforcement Conference in August of 1982 he had requested a history from someone at the site. That history was made available to you along with all the other documents which were made available in response to your first document request. That document was identified as being responsive to Specific Interrogatory 58. For your convenience, the document is enclosed with this letter. At pages 120-123 of the deposition transcript you request documentation concerning an alleged complaint by a Phillips-Getschow employee about the use of a six foot cheater bar to install the steam generator bolts. The only documentation known to exist which would indicate a complaint by a Phillips-Getschow employee is contained in NCR 612 (See page G0000521 attached) and a memo from Mr. Merwin to Mr. DelGeorge (See page G0000524 attached). Both'of these documents were made available to you and were included on the index for Specific Interrogatory 58. The memo concerns the installation of belts without heicoils. The NCR concerned damage to helicoils during installation. Again for your convenience, these documents are cnclosed with this letter. At pages 136-137 of the deposition transcript, you requested that the Applicant determine whether any NCR's were issued during the dispc ' tion of CECO NCR 332. The disposition called for NCR*. ) be issued only if a damaged part was repaired. Based on a review by contractor personnel, it has been determined that no NCR's were issued because all damaged parts found were replaced rather than repaired.

Robert Guild January 17, 1986 Page Three At page 144 of the deposition transcript, you request legible copies of two pages of a Braidwood Priority Item Report for October 31, 1985. The best copies available of those two pages are enclosed with this letter. At pages 159-162 of the deposition transcript you requested copies of the National Boiler Board Report on the MTV Program and the Taussig Report concerning the corroded pipe issue. Both of these reports were issued subsequent to Applicant's response to Intervenor's First Set of Interrogatories and Request to Produce. As provided in 10 C.F.R. 2.740(e), there is no continuing obligation to supplement a response to a discovery request unless the Applicant becomes aware of information which shows the response was incorrect when made or now makes the response incorrect. Neither exception applies to the Taussig Report or the National Boiler Board Report. However, again for your convenience the Taussig Report is enclosed with this letter. The National Boiler Board Report was provided to intervenors as Attachment A to the MTV Report which was the subject of a Board Notification on November 15, 1985. At pages 231-232 of the deposition transcript you questioned Mr. DelGeorge about a program description for the QCIRP program. The Applicant's reponse to Specific Interrogatory 7 of Intervenor's Second Set of Interrogatories and Request to Produce provides a description of the program as well as identifying the program's implementing documents.

Beck i 1 l ? 1 l ANS.BY L DATE l o f SUBJECT l Metallurgical Testing of Pipe Sampics l Per Consultant Specification No. 121, i i 1 'J0001402 j l

BACKGROUND: A total of 67 pipe samples were submitted to our laboratory for metallurgical testing in accordance with Sargent & Lundy Consultant Specification No. 121. These pipes were received from Commonwealth i Edison Company at the Braidwood Station on pipe sample transmittals from M.A. Gorski and represented various sizes from 1/2" to 2" o diameter. -Most of the submitted pipes had been pickled and reportedly displayed indications of corrosion and rusting. Twenty of the pipe samples were identified as new. The purpose of the testing was to determine if the corrosion or pickling had caused a significant degradation of the pipe properties. Consultant Specification 121 required nine tensile and chemical tests on pipes of various sizes to determine if it conformed to the rec uirements of ASTM A106-73a. Burst tests were to be performed on both new and corroded pipe in 1/2" and 2" diameters. Bend tests were requested on various size pipes to evaluate its ductility. Samples of good and corroded pipe in 1/2" and 2" diameters were also to be subjected to fatigue tests. Metallurgical and corrosion tests were requested to evaluate the severity of corrosion and the composition of the corrosion residue. The sample identification, size and heat numbers, as marked by Commonwealth Edison, are shown in Table 1. Photograph 1 is an illustration of the visual appearance of new and corroded pipe. TEST RESULTS: Tension Testing: The pipe samples identified as TS-1 through TS-9 were first subjected to tensile tests. Flat reduced section tensile test specimens were cut and machined from pipes TS-1 through TS-4 which represented 1-1/2" and 2" diameter pipes. This machining was per::ormed in accordance with ASTM A370. The remaining five specimens were of diameters 1" and under and were tested in full cross section. All nine specimens were tested with no preparation on the inside or outside diameters. All of the tests were performed in accordance with ASTM E8. The test of TS-4 failed to meet the elongation requirements. A retest was performed in full section on TS-53 which is of the same heat number and size. This retest is allowed by ASTM A106, Section 17. Insufficient material from TS4 did not allow its testing in full section. A full section retest was also performed on TS-2 of the same 1-1/2" diameter as a comparison between reduced and full section specimens in 1-1/2" diameters. The results of these tests are shown in Table II. 'J0001403

i d Report No. 60493-2 Page 2 Sargent & Lundy Except for TS-4 the test results shown in Table II meet the requirements specified by ASTM A106-75a for both full section and reduced section specimens, including the retest for Heat //JD1571 using specimen TS-53 in lieu of TS-4. The Grade B material requires a minimum tensile strength of 60,000 psi. and a minimum yield strength of 35,000 psi. The elongation minima are shown in Table II. All nine specimens exceeded the minimum elongation requirements. Chemical Analysis: The nine pipe sections subjected to tensile testing were also subjected to chemical analysis. All of the samples were analyzed for 15 elements to verify conformance to A106 and to identify any possible contaminants or unusual alloying additions. ASTM A106 specifies analysis of only 5 elements;

carbon, manganese, phosphorus, sulfur and silicon.

These tests were performed in accordance with ASTM A751. The results of this testing suggested that several specimens might contain silicon contents below specification limits. To investigate and verify this condition, a round robin retest program was established at our laboratory and at Chicago Spectro Services Laboratory. The results are shown in Table III. The results of these tests conform to the chemical requirements of ASTM A106-75a with no evidence of significant amounts of contaminants or unusual alloying clements. Burst Testing: Four tube samples, TS-10, TS-20, TS-30, and TS-40, were subjected to burst testing at Pittsburgh Testing Laboratories facilities in Pittsburgh, Pennsylvania. The ends of the 4' lengths of pipe were closed by welding or threading and plugging. A nipple was attached to one end to permit pressurizing the pipe with water. Each of the four pipes were pressurized with water until rupture of the pipe occurred. The water pressures required to rupture the pipes are shown in Table IV. Illustrations of the appearance of these fractures are shown as Photographs 2 through 4. 'J0001404

Report No. 60493-2 Page 3 Sargent & Lundy The burst test results revealed a slight decrease in the pressure sustained by the corroded pipe as compared to the new pipe. These variations may be expected due to differences in wall thickness between different pipes. ASTM allows for variations in wall thickness of 12.5%. All four of the test pressures exceed the minimum hydrostatic pressure specified in ASTM A530, Section 5 (3900 psi. for 2" diameter and 7400 psi. for 1/2" diameter). The visual appearance of the fracture of Sample TS-30 was slightly different from that observed in the other three pipes. Three pipes displayed a single linear fracture while TS-30 displayed a linear f ailure with fractures continuing at approximately 45 at each end. This condition is most likely due to minor residual stresses incurred during normal manufacture of the pipe and would not be expected to have any relation to the pitting or corrosion on TS-30. All of the tested pipe exceeded the minimum hydrostatic pressure specified by ASTM A530. Bend Testing: Nine pipe samples, TS-36 and TS-60 through TS-67, were subjected to bend testing. Each pipe was bent over a die with a diameter equal to or less than five times the nominal pipe diameter. (It should be noted that Section 11 of A106 normally requires pipe to be bent over a die of 42 times the nominal pipe diameter; specially ordered close coiling pipe is required to be bent over a die of 8 times the pipe diameter. The testing of the submitted pipe was more severe than either of these requirements.) This testing was performed at Wallace Machines facilities at 1800 W.

Cornelia, Chicago.

The bending was continued through an arc of 90 or more. No preparation was performed on any parts of the pipes prior to bending. No internal mandrel was used during any of the tests. A summary of the test results are shown in Table V. The visual appearance of the convex surfaces of the nine pipe samples are shown as Photographs 5 and 6. Examinations of the bent pipes were performed by a qualified Level III Visual Examiner. The visual examination of all bend tests revealed no indications of any cracks or other open defects on the nine pipe samples. These test results meet the bend requirements of ASTM A106. 'J0001405

Report No. 60493-2 Page 4 Sargent & Lundy ~ Fatigue Testing: Twenty pipe samples were subjected to fatigue testing at Materials Research Laboratory in Glenwood, Illinois. The 1/2" and 2" diameter pipes represented both the new and corroded conditions. No surface treatments or preparations were performed prior to testing. The load controlled fatigue tests were performed in 4 point bending (R= -1). With the 2" setup shown in Photograph 7, L=24 and A=8. For the 1/2" diameter pipe L=12 and A=4. L is the distance between the two outside loading points and A is the distance between adjacent loading points. All tests were performed at room temperature with results as shown in Table VI. The test results are tabulated in Figures 1 and 2 with comparison to results reported by A.R.C. Markl, " Fatigue Testing of Piping Components", Trans. ASME, April

1952, Page 289.

All of the failures occurred at one of the two center span loading points with the exception of the 1/2" corroded pipe. Five of the six specimens of 1/2" corroded pipe failed approximately midway between the loading points in the area of constant moment. The method of four point bending exposes greater areas of the pipe to the fatigue stresses than other methods of fatigue testing,. In four point bending fracturing may occur at almost any location between or at the loading points. j The graph of the test results shown in Figure 1 reveals the 2" samples to be within the results expected by Markl. The results of the 1/2" diameter pipe shown in Figure 2 is generally above the results expected by Mark 1. A copy of the Materials Research Laboratory report is attached as an appendix to this report. Macro-etch Testing: Macro-etch testing was to be performed on the nine pipe samples used for bend testing. Due to a delay in the shipment of these samples from Braidwood it was agreed between Taussig Associates and Commonwealth Edison Company that the ten pipes specified for corrosion evaluation, TS-50 to TS-59 would be used. A full section of each pipe was cut to a length of approximately 1/2". The cut face of each section was sanded to a suitable fineness for macro-etch testing. These specimens were placed in hot hydrochloric acid solutions as required by ASTM E381. After a suitable exposure time, the specimens were removed, rinsed, and i dried. Illustrations of the visual appearance of these macro sections are shown as Photographs 8 through 13. j0001406

Report No. 60493-2 Page 5 ~ Sargent & Lundy Visual examination of the macro-etch sections revealed all ten samples to display uniform structures with no evidence of inherent defects or weld seams. Several samples displayed evidence of some wall thickness variations. (Such variations are allowed by ASTM A106, however measurements of these wall thicknesses are outside the scope of Sargent & Lundy Consultant Specification 121.) None of the sections displayed indications of laps, cracks, laminations, segregation, or other irregularities. Though no requirements are specified by A106 for macro-etch testing, these results are typical of expected macro-etch samples for ASTM A106 type materials. E_DX Analysis: The surfaces of pipes TS-50 through TS-59 were all subjected to EDX analysis. Analyses were performed in the pitted areas on both the outside and inside diameters of all ten pipes. Using an ISI-40 scanning electron nicroscope, a 15 key electron beam was used to cause emission of characteristic x-rays. Energy dispersion x-ray (EDX) techniques were used to obtain semi-quantitative chemical analyses of the examined surfaces. The results of these tests are shown in Table IX. Illustrations of the EDX spectra obtained from the examined samples are shown as Photographs 24 through 30. 'The results of these analyses revealed iron to be the primary constituent in the pitted areas. Numerous other elements were identified in trace amounts. The most common trace elements were found to be aluminum, sulfur, and silicon. It may be estimated that each of these elements are in concentrations of less than 5%. The limit of detection is estimated to be approximately .1 to.5% for most elements. The results had good correlation with the results of the deposit analysis. It should be noted that EDX analysis is insensitive to elements of atomic numbers less than 10 including hydrogen, oxygen, and carbon. Only sample TS-57 displayed significant amounts of a secondary element. Phosphorus was found in greater than normally expected amounts on both the O.D. and I.D. of this sample. The phosphorus may be remnants of iron phosphate or zine phosphate used as a lubricant during drawing operations. These materials may also inhibit corrosion during pickling operations and may explain the limited corrosion observed on this sample during metallographic examination. 'J00 1407 3

Report No. 60493-2 Page e Sargent & Lundy pH Testing: A drop of deionized water was placed on the outside surfaces of pipes TS-52, TS-54, and TS-58. The water was spread to form a film. After approximately 5 minutes, a piece of pH paper was used to evaluate the acidity of the water. The deionized water was found to have a pH of 6.0. The water on the pipe surfaces exhibited the exact same color indicative of 6.0 pH. The pH paper used positively identifies changes of 0.4 pH and should be capable of distinguishing changes of 0.2 pH. This testing indicates that the sulfur and chlorine on the pipe. surface are not in sufficient quantity or are not adequately chemically active to cause significant amounts of sulfuric or hydrochloric acids to be formed when exposed to water and would therefore not be expected to cause any significant reduction in the life of the tubing. Meta 11ographic Examination: Meta 11ographic cross sections were cut from the ten pipe samples used for macro-etch testing. These sections represented the full wall thickness of each pipe from the outside diameter to the inside diameter. All ten sections were mounted in bakelite molds to facilitate grinding and polishing to a.05 micron finish. A metallurgical microscope was used to examine the cross sections at magnifications of up to 1000X. A solution of Il Nital was applied to the specimens to provide clear definition of their microstructures. All ten of the examined sections displayed microstructures typical of low carbon pipe products such as ASTM A106. The 2" and 1-1/2" diameter samples displayed microstructures of pearlite and accicular ferrite. This may indicate these pipes were hot worked. The smaller diameter pipes generally displayed more equiaxed ferrite and pearlite indicative of a cold worked and annealed product. Both methods are acceptable means of forming per ASTM A106. Some partial decarburization was detected on the outside surfaces of several of the tubes extending to depths of up to .006". The inside diameter of sample TS-52 exhibited a layer of total decarburi-zation approximately.0025" thick. A small lap was observed on the inside circumference of TS-53 which is acceptable per Paragraph 20.3.1. These decarburized layers may not be considered unusual or excessive for this type of product. No evidence of inherent metallurgical defects were observed in any of the examined secJions such as excessive inclusions, cracks, laps, laminations, or seams. Illustrations of the microstructures and surf ace appearances of these metallographic sections are shown as Photographs 14 through 23. 'J00 1408 3

Report No. 60493-2 Page 7 Sargent & Lundy Some pitting was observed on the surfaces of most of the metallo-graphic cross sections. These corrosion pits were relatively broad and shallow. The maximum depth of these pits was measured and are shown in Table VII. The most severe corrosion was observed on the outside diameter of sample TS-58. Most of the outside surface had corroded and only isolated areas of the original outside diameter of the as-manufactured pipe were identified. In general the nine sections displayed only isolated areas of pitting. Sample TS-57 exhibited the least pitting and it may have been due to normal processing and production techniques rather than the pickling treatment. None of the examined sections displayed evidence of other surface conditions such as intergranular or grain boundary attack, stress corrosion cracking, or indications of embrittlement. The results of the metallographic examinations revealed microstructures typical of ASTM A106 material though no specific requirements are stated in the specification. Deposit Analysis: Sections from the tubes identified as TS-50 through TS-59 were submitted to

Dearborn Chemical in Lake Zurich,

Illinois. Samples of loose scale on the outside diameter of these samples were obtained by using scotch tape. Because of the relatively small amount of sample obtained by this method, only semi-quantitative chemical analyses wefe performed on the individual samples. To obtain a quantitative analysis, all of the scale obtained from the ten tubes was combined for a composite analysis. The results of this x-ray fluorescence testing is shown in Table VIII. In general, the scale samples were found to have iron as the primary constituent with trace amounts of manganese, calcium, chlorine, and silicon. The most unusual sample would be TS-57 which displayed minor amounts of zinc, manganese, calcium, sulfur, silicon, phosphorus and lead. A composite sample was obtained by combining all the scale removed from the ten pipes. It was found to be 83% iron. No measurable amounts of chlorine were identified. The elements which were identified by these analyses may be con-sidered relatively inert and would not be expected to cause additional corrosion. 300:1409

a 1 e _ _ _. + 3. a -a Report No. 60493-2 Page 8 Sargent & Lundy 1 i 1 CONCLUSIONS: The tensile and chemical results from corroded pipes TS-1 through TS-9 all conformed to the requirements of ASTM A106-75a, grade B. The outside surfaces of the tensile specimens were not machined or otherwise prepared which indicates the effects of the corrosion in tension may be negligible. The burst tests resulted in slightly lower values for the corroded pipes but all values exceeded the minimum hydrostatic test pressure specified by A530. The corroded pipes TS-36 and TS-60 through TS-67 were subjected to bend tests and exhibited no defects af ter bending over a more severe diameter than required for specially ordered close coiling material. 4 The fatigue tests were peformed in four point bending on 2" and 1/2" diameters in both the new and corroded conditions. The results were compared to those expected by Mark 1 and good correlation i 4 was found. The corroded pipes displayed slightly lower test j results but were within the range expected by Mark 1 for the 2" and above the expected range for the 1/2" pipes. The corrosion may have caused a small degradation of fatigue properties but has l not brought it below the values expected by Markl. The decrease may be due to differences in the actual wall thicknesses rather l than any effect of corrosion or pitting. 1 The macro-etch testing revealed corroded pipes TS-50 through TS-59 to have structures typical of A106 with no indications of significant i defects. The metallographic cross sections of these same pipes l exhibited broad shallow pits apparently due to corrosion. No other effects of corrosion were observed including stress corrosion cracking, intergranular corrosion or embrittlement. The microstruc-tures were typical of low carbon steels with no evidence of microscopic defects. Analyses of corrosion deposits of samples TS-50 through TS-59 indicated iron as the primary constituent. The other elements of the corrosion were present at relatively low concentrations. These elements included manganese, silicon, calcium, aluminum, chlorine and sulfur. No unusual differences were observed between the deposit analyses performed on debris from the pipe surface and EDX analyses performed in pitted areas. On 3 corroded pipes, exposing the pitted outside pipe surface to water caused no significant change in pH and would not be expected to cause any l 4 'J00 1410 3 1 4 ,,-,..ne- .n

Report No. 60493-2 Page 9 Sargent & Lundy significant reduction in the life of the tubing. This indicates that the sulfur and chlorine present in the pit areas may not be active or capable of producing significant amounts of hydrochloric or sulfuric acids. Based upon the above test results it appears that the corrosion of the submitted samples may have generally caused a slight decrease in properties but meet or exceed the requirements of expected values for the specified materials. In view of the acceptable test results we may expect this material to perform in a similar manner to ASTM A106 material which has not been pickled with no significant degradation of service lifetime.

Dear Mr. Hineman:

Lengths of 1/2" and 2" diameter schedule 60 pipe, supplied by you, have been tested in fatigue. It was the purpose of these tests to compare the fatigue properties of the " normal" and " corroded" surfaces Load controlled fatigue testing was on these four lots of pipe. carried out in four point bending (R = -1) in a setup as shown in Fig. 1. The 2" setup (t a 24", a - 8") is pictured and the 1/2" setup was similar except that 1 - 12" and a - 4". These room temperaturg and tegts were run at stresses expected to produce f ailures between 10 10 cycles. The results of these tests are collected in Table 1 and are These figures are plots based on plotted in Figs. 2 through 7 stresses calculated on this schedule 80 pipe using both nominal pipe dimensions and/or actuf1 dimensions. All results are also compared to the results reported in Fig. 4 of " Fatigue Tests of Piping Components", by A. R. C. Markl, Trans. ASME, APR.1952, p. 289. Failures were, in all cases except for the 1/2" corroded pipe, This was located at one of the two center span loading points. anticipated since the maximum stress occurs here and an additional gripping stress is also present. Of the six specimens of 1/2" corroded pipe run f ailure occurred in five specimens, away from the loading points into the area of constant moment (stress) in the center of the span.

Dear Mr. Westermeier:

As you requested, we have reviewed the enclosed Camonwealth Edison Capany Nonconf ormance Report L-413 f or Braidwood Station, Unit 2. This nonconf ormance concerns misalignment of the holes of the steam generator f oot and the holes in the steam generator column. This misalignment results in an interf erence in the bolt with the coltaan top. The resolution of this nonconf ormance is do-cumented in FG L-6 926. This FCR allows the hole in the column top to be slotted by grinding up to.3/32" utili zing the 1/8" thick A325 washer provided with the bolt and up to 3/16" with a 1/4" thick A325 washer.
