SUBJECT:

THREE MILE ISLAND NUCLEAR STATION UNIT 1 (1MI-1) OPERATING LICENSE NO. DPR-50 DOCKET 50-289 IGSCC INVESTIGATION

Background

References B and C provide status of inspection results at the time to IE Bulletin No. 79-17 dated July 26, 1979. Attached herein (Attachment 1) is an updated status report of the now completed phase I and II ultrasonic inspection. Met-Ed feels confident that through our screening procedure, we have identified all welds which have significant IGSCC. In fact, and as we have pointed out on several occasions, there is a high probability that the 42 reported indications include several " heat affect areas" without evidence of IGSCC. The latter would result from indications emanating from the actual weldments. Also included in Attachment 2 is a mapping of the reported indications. Discussion The purpose of this letter is to request NRC approval for the metallurgical repair proceaure and selection of materials specification used for the replacement. It is requested that a response be provided to the above no later than November 15, 1979 as the replacement materials ordered will by then be in-house.

Director of Nuclear Reactor Regulation U. S. Nuclear Regulatory Commission Page Attachment 3 - Gas Tungsten Arc - Shielded Metal Arc Welding of Stainless Steel in Borated Water Systems - Catalytic Welding Procedure Specification No. SP-4200-55(N) 102A - Evaluation of I.D. Buttering Techniqueto Minimize Weld RAZ Cracking, Lab No. 56052 It is our intention to perform repairs to IGSCC affected areas using the methodology as described in Attachment 3 in conjunction with Attachment 4 Welding Procedure Specification SP-4200-55(N)102A. The I.D. buttering process will be utilized in situations where an existing 304 SS is to be connected to a 304L stainless steel replacement section, and used only on the 304 SS side. In cases where the weld joint will be 304L to 304L, the buttering process will not be employed. As we have discussed with your staff on October 3, 1979, we anticipate providing you in the near future, our anticipated surveillance program for moniterlag IGSCC in the future. A final report on this subject will be issued by November 30, 1979. Very truly yours, d s r',\\ ,( p wCh6[? J. G. Herbein Vice President Nuclear-0perations JGH:NCK:ks Attachments ^~0 299

Scope This welding procedure shall be utilized when making welds and weld repairs on the 304 SS and 304L SS piping in the following systems: A. Spent Fuel B. Decay Heat C. Building Spray D. Make-Up E. Core Flood Included in this procedure are the requirements specifically related to producing a corrosion resistant I.D. weld overlay (I.D. But tering) on the ends of existing 304 SS pipes as recommended in NUTEG-0313. Also, as recermended in this document, aherever possible, replacement stainless steel piping material will contain.035% Carbon max. 2. Welding Procedure Soecification (WPS) The basic WPS defining the essential variables to be utilized for this repair are contained in Catalytic WPS No. SP-4200-SS(N)-102A. Non-essential variables specifically tailored for this repair are defined herein. The basic weld procedure specification shall have been qualified in accordance with the requirements of ASME:Section IX and Regulatory Guide 1.31. 3. I.D. Wo.ld Clad (Butterine) When butt weld joints are to be made between replacement 304L SS piping and the original 304 SS piping in the system. the 304SS pipe ends shall be prepared in the following manner:

_. ~.. - 3. I.D. Weld Clad (Buttering) (Continued) A. If the pipe end has been thermally cut, a minimum of 1/8" of metal must be removed from the cut and to eliminate the heat-affected-zone (HAZ) from the cutting operation. B. Clean the pipe end per WPS 4200-SS(N)-102A. C. Weld clad the I.D. surface of the pip. end to a width of 3/8" + 1/8" - 0 with a single layer of SFA-5.9 Class ER 308L filler metal with 5 FN minimum ferrite, using the GTAW process. (See sketch I). D. Maximum joulian heat input as established during the I.D. weld clad qualification (GPU Lab No. 56052 rev.1) shall be 17,100 joules / inch utilizing the following electrical characteristics: Arc Voltage 8 - 12 volts Current 80 - 95 amps Travel Speed - 4 in./ min. E. Maximum interpass temperature shall be 100* F. F. After the I.D. weld cladding is complete the pipe end shall be ground backel/8" to assure the weld clad becomes integral with the weld root. The butu weld joint geometry shall then be prepared by maching or grinding. Joint geometry shall be a 37-1/2* t 2-1/2* single bevel with a 3/32" + 1/32' land. NOTE: Grinding shall not be performed on the weld clad or pipe internal surfaces except in the immediate vicinity of the weld root to facilitate joint fit up and then only light grinding is permitted to remove high spots. i Maximum I.D. mismatch on fit up shall be 1/16". 4. Butt Weld Procedure A. Butt welding shall be in accordance with Catalytic WPS 4200-SS(N)- 102A.

4. Butt Weld Procedure (Continued) B. The root and first pass shall be deposited by the GTAM process utilizing SEA-5. 3 Class ER 308L filler metal with a minimum of 5 FN ferrite. Argon gas backing shall be utilized during the first two passes. C. The weld shall be completed utilizing the SMAW process with SFA-5.4 Class E308L-16 electrodes with a minimum of 5 FN ferrite. D. Maximum heat input during the welding shall be 35,000 joules /in, with a 300*F max. interpass temperature. E. Electrical characteristics shall be as follows: GTAW SMAW Voltage 10 - 12 volts 20 - 23 volts Current 75 - 95 amps 80 - 100 amps Travel Speed 2 - 4 in./ min. 4 - 6 in./ min. 5. Quality control A. The quality control inspector shall verify the following:

1) Correct materials, including filler metals, are being utilized.

2) I.D. weld clad and joint geometry dimensions are correct.

3) Joint fit up has correct dimensions and aligmment.

B. Quality Control shall also perform spot checks to assure proper electrical characteristics and interpass temperatures are being utilized during welding. C. Quality Control shall perform final visual inspection per the applicable quality control procedures. ~'0 307 9/2f/79

Buttering Technique to Minimize Weld HAZ Cracking, Lab No. 56052 (REVISION #1) To N. C. KAZANAS Location-Reading In order to qualify a field welding procedure for joining 304L SS to 30** SS which would minimize the potential for intergranular stress corrosion cracking (IGSCC) in the 304 SS weld heat-affected-zone (HaZ), a sample was prepared for evaluation utilizing a proposed I.D. buttering technique. This sample consisted of two sections of 8" schedule 40 piping; one section 304 SS (HT.334165), the other section 304L SS (HT.83602000). To one-half of the I.D. circumference of the 304 SS pipe a layer of ER308L SS (HT.760133) approximately 1/8" thick was deposited by the GTAW process to a width of approximately 1/2" (Figures 1 & 21 This deposit was applied at 8-10 volts, 80-95 amps. Af ter this weld deposit had been applied, the joint geometry was then machined at this clad end. This section of pipe was then butt welded to the 304L SS pipe. The root pass was made by the GTAW process at 90 amps with argon gas backing. This pass was allowed to cool to ambient temperature at which time a second pass was made at 95 amps. When the interpass cemperature had reached 120*F (this was the actual reading -- the spec required 300*F max. interpass temp.) a final cover pass was made by the SMAW process at 85-90 amps. Half this circumferential weld deposit was made with a weave bead and half with stringer beads (see sketch). This was done to assess the cover pass weld technique's effect on sensitization. Metallurgical Evaluation To evaluate the suitability of this welding procedure to minimize the propensity for ICSCC it was decided that the HAZ structures would be evaluated by the oxalic acid etch test (A262 prac. A) for the degree of sensitization. Metallographic specimens were prepared transverse to the butt veld from the four quadrants of the pipe. These specimens included the weld and both RAZ's. After the specimens were etched, the RAZ areas showing the highest degree of sensitization on the I.D. were photocicrographed. Conclusion The degree of sensitization in the RAZ adjacent to the I.D. weld clad is significantly less than that which has been observed to be associated with the current pipe cracking. Based on tnis observation, it appears that I.D. weld clad, deposited with good control on heat input, will be beneficial in , minimizing the potential for IGSCC and therefore should be utilized when joining new spools of 304L SS to existing 304 SS pipe ends. No difference in degree of sensitization at the I.D. was observed between the weave or stringer bead cover pass. ~~0 334 3 mn,2...e......-- - - -.. ~ ~ ~ ~. - * *.. " " ~

I? ? N. C. KAZANAS Se p tember 27, 1979 As would be expected, the 304L SS (.016% C) heat-af fected-zones showed no evidence of sensitization, further supporting this material's use in the borated water environment. / W, ' / } N SCOTT G BBE FSG:brk cc: T.
