NIAGARA M0 HAWK POWER' C0iP0 RATION NINE MILE POINT UNIT 2 DOCKET N0. 50-410 Final _ Report for a Problem
. Concerning. Pipe Material Supplied By Guyon Alloys (55(e).- 84-08)
' Description of-the: Problem'
,The problem pertains to certain items of ASME pipe material supplied by Guyon L Alloys, Incorporated, under. Field Purchase Order No. NMP2-FP0-12345.
Guyon
- Alloys had ' purchased _.this: material from Sharon Tube Company, Sharon, Pennsylvania.
Guyon ; informed Stone &; Webster. Engineering Corporation that
'during an. audit of-the.Sharon Tube quality program, it was discovered that <
under strict-interpretation of;ASME-Section III rules, certain items of SA&l05 EGrade 'B pipe were not actually manufactured by'Sharon Tube although so
-indicated-by. Certified Material' Test Reports pro.vided by Sharon Tube to~ Guyon s
Alloys, Incorporated.

iSharon Tube: furnished to Guyon Alloys certain items of hot-finished or rolled
..pipecl ' inch NPSf through ~1-1/2' inch NPS which, according to Guyon Alloys; _'were a
- manufactured by U.S. Steel at' Gary, _ Indiana, under its qualified NCA-3800' E
- quality program.to. the chemical,' finish and dimensional requirements -only of
- A-106.. Upon receipt, Sharon; Tube performed.mechinical' tests as required by :
iSA-106 '(i.e., : tensile, bend -and' hydrostatic)/trinned or faced ends and fapplied final coating'and markings but' did not affect the ' material
- properties.
Sharon-Tube: issued and supplied Certified Material Test--Reports r to; Guyon Alloys,' Incorporated which certify that the pipe was produced in accordance with its : qualified quality program. : These~ Certified Material Test-'
Reports incorporated the results of tha Sharon Tub'e mechanical tests"alo,ng s

'Upon;receiptiof the subje'dt matref al, Sharon Tube performed mechanical tests' s!
e
'as_ required bylSA-_106, trimmedlo7 faced. ends and applied final coatings and markings;but didinot. affect material properties. Sharon Tube should.have

Ycertified this9iaterial f only :inj the' capacity of _a. supplier of ASME material,
- n I
- ratheri thanlin.the capacity _ of"a manufacturer.. HoweveF, as indicaYed by Guyon
' Alloys, the. material. was manufactured by U.S. Steel un' der a qualified :NCA-3800 tquality' program and was: certified to' conform to _ ASTM A-106., Therefore, we are lof the opinion that this'is not a significant quality breakdown and that 1( "
fthis'problemtwere.to-have. remained 6ncorrected, it would not have adversely
'affected theisafe~ operation:of the: plant.-'Hence, the criteria,for
'~
ireportability under 10CFR50.55(e) have not been met.
