FLORIDA POWER & LIGHT COMPANY December 17, 1984 L-84-377 Mr. J. P. O'Reilly Regional Mninistrator, Region II U. 'i. Nuclear Regulatory Commission 101 Marietta Street, N.W., Suite 2900 Atlanta, GA 30323
Dear Mr. O'Reilly:
Re:-Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-251 IE Bulletin 83-06 Our letters L-84-259, dated September 28, 1984, and L-84-318, dated November 8,1984, provided additional information to supplement our response
.to IE Bulletin 83-06 (Non-Conforming Materials Supplied by Tube-Line Corporation,etc.). The disposition of the Tube-Line material that was reported in our September 28, 1984 letter is attached.
A status report on the material reported on our November 8,1984 letter is also attached. A status report of our documentation review of Gulfalloy material and any additional Tube-Line material is still scheduled for January 4,1985.
We have also reviewed the remarks on this subject in Inspection Report 84-37/38. Because we have only recently received this request to comment on j
these remarks, we will review our reporting-responsiveness of this subject and provide comments with our status report scheduled for January 4,1985.
Should you have any questions on this infonnation, please contact us.
Ver truly yours, J. W. Williams, Jr.

ATTACHMENT Re: Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-251 IE Bulletin 83-06 Disposition of Gulfalloy supplied Tube-Line Corp materials received under Purchase Order 38497-39056C DWA 38625 1)
Item 25:
15 items - 1 1/2" C/S 150# flanges, ASTM A-105
)-
All 15 items are currently in the QC hold area in the warehouse.
As these flanges have not been utilized in any system, they do not constitute a safety concern.
DWA 38624B 1)' Item 7: 6 items - 3" x 2" C/S conc. reducer, ASTM A-234 GR. WPB Of the 6 reducers purchased, 2 are currently in the QC hold area and 4 are
. installed in the control building chilled water system per drawing 5610-M-1003F at FW Nos. 38, 71, 95, and 108.
, As all 6 reducers are members of heat H8002, supplemental testing was
' performed by a qualified laboratory on one of the 2 reducers in the QC hold area. As the chemical and physical test results of heat H8002 are consistent with the requirements of ASTM A-234 GR. WPB, the installed items are acceptable for continued use and the remaining reducer in the QC hold area may be released for.use as is.
DWA 39541 1)
Item 7: 6 items - 3".x 3" x 2" C/S tees. ASTM A-234 GR. WPB Of the 6 items ordered. 2 are currently in the QC hold area and 4 were installed in the control building chilled water systen per Drawing 5610-M-1003F at FW Nos. 37, 70, 94, and 108.
As all 6 tees are members of heat EYC, supplemental testing was performed by a qualified laboratory on one of the two tees in the QC hold area. As the chemical and physical test results are consistent with the requirements of ASTM A-234 GR. WPB, the installed items.are acceptable for continued use and the remaining tee in the QC hold area may be released for use as is.

Item 11: 8 items - 3",150# C/S flanges, ASTM A-105 Of the 8 items ordered, 7 are currently in the QC ho~1d area and I was installed in the control building chilled water system per Lrawing 5610-M-1003F at FW No. 73. As the 8 flanges were from 2 different heats, members of both heat NEZB and EBME were subjected to testing by a qualified laboratory. As both test results were consistent with the requirements of ASTM A-105, the installed flange (heat NEZB) is acceptable for continued use and the remaining flanges from both heats in the QC hold area may be released for use as is.
3)
Item 16: 4 items - 2" 150# C/S flanges, ASTM A-181 GR 11 Of the 4 items ordered, 4 are currently in the QC hold area in the warehouse. As these flanges have not been utilized in any system, they do not constitute a safety concern.
0 4)
Item 17: 24 items - 1 1/2" 150# C/S flanges, ASTM A-181 GR 11 Of the 24 items ordered, 8 are located in the QC hold area, 8 flanges were installed and subsequently scrapped due to vendor error (Backcharge No.
375.1051), and 8 are installed in the control building chilled water system.
(FSK-M-1654 FW Nos. 52, 55, 120 and 121; FSK-M-1673 FW Nos. 45 and 46; FSK-M-1664 FW Nos. 38 and 39).
As all 24 flanges are members of the same heat, supplemental testing was performed by a qualified laboratory on one of the 8 flanges in the QC hold area. Chemical testing provided parameters that are consistent with the requirements of ASTM 181-GR11.
Physical testing showed strengths of 32.6 ksi/70.3 ksi versus code minimums of 36 ksi yield and 70 ksi tensile.
Under ANSI B31.1 the bases for establishing stress values are the same as those in ASME Boiler and Pressure Vessel Code,Section I, Appendix A-150. Accordingly for this application, the allowable stess for the flange i
material may be taken as the lower of 1/4 of the tensile strength or 5/8 of the yield strength. As the tensile strength is the controlling parameter for this material and as the tensile strength exceeds the minimum :pecified strength of 70 ksi, the installed flanges are acceptable for further use.
5)
Item 18: 8 items - 1" 150# C/S flanges, ASTM A-181 GR11 Of the 8 items ordered, 5 are located in the QC hold area. Six were
. issued for use in the control building chilled water system but 3 were later returned. The 3 flanges installed in the system (FSK-M-1654) were later removed when the flange rating was changed to 300#.
As none of these flanges are utilized in this sytem, they do not constitute a safety Concern.

Status b
By inspection, FPL has determined that all of the subject fittings were i
either permanently installed in the steam supply piping of the Auxiliary 4
Feedwater System or temporarily used during system flushing and were subsequently discarded.
As a result there may not be any spare fittings N
from the subject heats that could be used for chemical analysis.

Plan for testing
-E
=
The chemical and mechanical properties, as specified in ASTM-A-234 for i.
Grade WPB Schedule 80 fittings, must be verified. At least one fitting C
from each heat must be tested.
Spare components may be used, if j
available; otherwise, samples must be obtained from the installed g
components. The samples may be obtained from the existing installation by replacing existing fittings with new, qualified fittings during a
-j scheduled outage of either unit consistent with the limiting condition of d
operation for the Auxiliary Feedwater System, as defined in Technical 9
Specification 3.8.
__q Testing will be performed by an independent party under a qualified d
program, as approved by Florida Power & Light Quality Assurance. The test 5
results will t,e submitted to Engineering for approval and final A
disposition.

Justification for Continued Operation These pipe fittings were installed under the Florida Power & Light Quality d
Assurance and Quality Control Program. The installation has been E
inspected in accordance with appropriate nandastructive examinations and 2
tested by hydrostatic pressure and initial service leak test 3 for i
integrity.
In addition, since the implemented modifications have been
]
completed the system has been subjected to saveral cycles of startup, 4
shutdown, and testing operations witbout indication of pipe integrity J
failure. Therefore there is considered tb ee substantial justification j
for the system and plant to continue opention until final disposition and g
corrective actions are implemented.
