\ 1. Relationship of Parties By contract, Ucstinghouse is responsible for supplying the piping for .the primary coolant system of PGLE's Diablo Canyon Unit No. 1 nucicar plant. Westinghouac,.in turn, has contracted to purchase the fittings to be used in the

, system from Electric Steel Company (ESCO). located in Portland, Oregon. ESCO operates a foundry wherein such components are cast and fabricated.

When a particular component has been accepted by Westinghouse from ESCO, the component is tentatively assigned to a specific projcet, nowever, Westinghouse reserves the right to rea.:aign components to other projects. Therefore, it cannot be stated with certainty that a particular component 1 caving JSCO will be unconditionally appropriated to the contract existing I between PG&E and Westinghouse for the primary piping systou of Diablo Canyon Nucicar Plant No.1.

2. Purchase Order Specificatior.s The inspector reviewed the purchase order given to ESCO by Westinghouse for fittings to be used in fabricating the primary piping system for the Diablo Canyon nuclear plant.

The order 1 poses upon ESCO, conditions relative to design, materials, applicable codes, quality control, nondestructive testing and documentation to show that the conditions have been performed. The following information was obtained from the review of the purchase order-

a. Specification of Fittings The purchase order specifications for the fittings werc l consistent with the requirements prescribed in Section 4 1 of the Preliminary Safety Analysis Report fur Diablo Canyon Nuclear Plant No. 1. Specifically, the desir,n

. . . . ,~ -

... .. - 2 ntipuu.ccd tu be 2/,LJ pain aad 6Lv'i, re:,pe c t ive ly.

The urder also proscribed the dimcasions of the fitting 3 and that the fittings be cast of catorial conforming to the standards of ASTM-351-C76M with a maximum cobalt content of 0.27..

b. Quality Control acquirements l The specifications of the purchas,c order concerning quality control requirements were obscrvod to be consistent uith the requirements of the prolininary i safety analysis report for Diablo Canyon No.1 nucicar plant in that: j i

)

\ (1) The design analysis was specified to. roc; ,rc compliance with the requirements of USA d.I.

331.1 codo for preasure piping.

(2) The specified nondestructive inspection requirements included dye penetrant and radiographic testing.

(3) Conditions wer.c included which requ. : that ESCO submit the manufacturing proceduces (e.g. uciding, heat treat =cnt, cic.. Gng and inspection) to Westinghouse for ccview and approval.

(4) Provisions have been included whereby Westinghouse has the right of inspection and in cortain arcas the duty to inspect and approve recorded results of tests.

(5) Repair of defcets are required to be approved by Westinghouse.

3. Component Quality To determine whether or not ESCO is properly impicmenting the quality Control Program to assure that the pipe fittings are manufactured in accordance with the purchase order specifications, the inspector reviewed availabic documentation concerning a 900 fitting currently assigned to PG&E's nucicar plant. At the prcsont time, onc 900 and four 400.fittingc have been tentatively assigned to the Diablo Canyon project, according to Mr. Page of Westinghouse. From the review of the documentation and discussions with Messrs. Roose, Pago and Waters, the following information was' obtained. .
a. Material Identification t

All components are identified by heat numbers. A particular number is assigned a particular heat of i metal. The number is provided for in the molds and thereby cast directly into both the component and  !

corresponding test coupons when the metal is poured.

This heat number is later included on an information plate which is later welded to the component. All information concerning a particular component can only be traced through the heat number.

3 b. Design Analysis -

A stress analysis of the fitting was performed by ESCO personnel. According to Page, the analysis rep)rt contained in the data package has been reviewed and approved by competent Westir.shouse design parsonnel, c, . Casting The 900 fittings arc, cast in horisontal halves and later welded together. The casting molds are of selective sand,

d. Material specification .

Prior to pouring a particular heat Hof metal a macs spectrographic analysis is performed of the metal to ascertain whether or not the chemical cc= position conforms wich the prescribed specifications. Latet, '

after casting, additional analysis of the metal is performed to det.*rmino che chemical composicion of the material. The . red test coupons are also cosced to determine the aaaical proporties of the cetal.

For the particular fitting under review by the inspector, the information contained in ESCO's

, metallurgical report of analyses showed that the 3

material conformed to the contract specifications as to both chemical and mechanical properties.

i

e. Heat Treatment ,

i Subsequent to welding and repairs, the entire fitting is subjected to heat treatment-at temperatures of approximately 20000F for a duration of approximately

  • four hours. The specifications required heat treat-ment at a te.,perature in n:: cess of 19500F for a

.lo cat i ..: oi c . . . . tr pa r iach o i ..c e' .re.m .

Recordings oi cha haac creatments were iue..;;i' led by an appropriato stamp with provisions' included to show that the treatments had bocn reviewed and approved by Westinghouse. Mr. Page stated that the ESCO heat treatmeat procedures have been approved by Westinghouse.  ;

s i f. Welding Procedure The procedure used for welding the compone.ms is an ESCO standard proceduro. Mr. Page stated .: bat as per the contract provision, Westinghouse has . viewed and approved the procedure. Also, of note, Mr. Waters stated that ESCO manufacturcs components for the U. S.

. Navy to be used in nuc1 car systems and thac ::he procedure also conforms to the requirements of the Navy for like work.'

g. Welders Wolding personnel are qualified for certain work by

, ESCO as por Section IX of ASM3 Eoiler and Pressurc Vessel Code. The qualifications are reviewed by the Defense Contract Administrative Services Office (DCASO) located in Portland, Oregon. According to Mr. Waters, welders carry a card shouina their qualifications, ne added, however, that the wolding supervisor is respons-ible to assure that only qualified uciders work on the particular macerial in question. Wolders arc requalified quarterly, according co Mr. Waters. Mr. Page stated that the welders qualificacions are reviewed by Westinghousc. Also, welders are identified in the records as to the work perforacd.

h. Welding Rod Mr. Waters stated that due to previous probicms of controlling welding rod material, strict administrativa controls have been implemented. All rod material is stored in a separato room and only the welding super-visor may authorize withdrawal of rods from storage.

The rods are given an 2SCO identification nu:aber which is then used to identify the welding rod to be used on

, a particular job. Waters added that when a wclder completes his uork, he is required to return all unused material. -

According to Waters, instancos have occurred where the welding nutcrial has been other than stipulated when obtained from che manufacturcr of the rod. To climinate this possible gap in control, a sampic of rod material is now analyzed when roccived from the vendor to assure that the rod caccrial is properly identified. i

9

i. Nondestructive Testing The records of nondestructive testing of the primary system fittings indicated 1007, coverage by both liquid penetrants and radio;raphy.

Subsequent to repair 22 defects and heat treatment, the repaired areas were rechecked. Mr. Waters stated that the records cantain the complete history of all repairs and tests.

The radiographs are read by two individual ESCO employees and then viewed by a Wootinghouse inopcetor who signs the record indicating approval and acceptance of the product. Those radiographs are then viewed by ,

a PG&E inspector according to Forbes.

The contract specifications require that the radiographs be mado in accordance with the provisions of ASTM E94-62T and accepted in accordance with ASTM E-136-6ST, severity level 2 cxcept that cacogorics D & E are unacceptable. The radiographs are produced using type AA film with a cobalt-60 source. According to c report of PG&E's inspector, "the radiographs we-of reasonobly good quality with the 3.0 penetrar.~. .

easily readable."

The records and cortifications by ESCO and Westinghouse  !

showed thct the *above requircracnts have been complied i with before the fittings have been accepted by '

Westinghouse. Although rccords concerning the radiographs are transmitted to Westinghouse, the film itself is retained by iSCO.

k. Pickling According to both Westinghouse and ESCO perconnel pickling of the component is excluded froa cae manufacturing proccca.

,1. S t ora ge Fittings were obsenved to be stored on wooden plates in the storage yard. All fittings were wrapped in plastic.

m. Shipping Mr. Page stated that che fittings will be shipped in a closed gondola car and that the components will be appropriately secured to prevent damage in transit. Soma littings have, in the past however, been shipped via flatbed cars according to Page,
n. Documentation r 3ased on the inspector's rovit.= all of ESCO's documentation pertaining to nucicar plant fittings manufactured for Westinghouse appeared to adequately show that the component had been manufactured as prescribed by the conditions of the contract. The contract between Westinghouse and ZSCO provides that copics of all documentation concerning the fittings pass with delivery of the components to Westinghouse.

Mr. Roose stated that copics of the documents related to a particular fitting pass to PG&E when appropriate as por the conditions of the Westinghouse and PG&E ,

agreement.

o. Westinghouse Inspections Mr. Page stated that under the Westinghouse-ESCO contract, Westinghouse has the r!ght to encer ac any time to observe work in process, and that all documentation is reviewed by a representative of Westinghouse to determinc ESCO's performance of the conditions contained in the agroomant.

p. PG&E's Insocctions
  • Mr. Forbes informou the ir.spector that representativos of PG&2 have audited cocumentation and test results at ESCO on two separate occasions prior to the current visit. He added that no significant deficicacies had been identified by the 2C&O inspectors. He also showed the inspector the reports prepared by- the PC&E inspectors subsequent to the visits. No deficiencics concerning ESCO's activitics were identified in the reports.

D. Dresden II Recirculation Pe- ? ".oction Covers W. E. Vetter met with Mossrs. Grachart , Oldhaa and Zicbcli, for a review of recorda associsced with the three primary recirculation systca pu.ap suction covers which were manu-factured for the Dresdca : reactor. The significant results of the review are as follows:

1. The three covers were identified as P.O. No. V-48666 (C2 to Byron Jackson) and P.O. No. 615313 (3yron Jackson to CSCO) .
2. They were manufactured during July-Au;ust, 1966.
3. Two of the covers are identified as heat numbers 5114-1 and 2 and the third as heat number 5147-1,
4. The base material w'as cortified (mill certification) as conforming, per purchase order requirements, to ASTM-A315 and C75M. l S. Nondestructive tcst- (radiograph and dyc penetrant) reports and repair charts disclosed that one m2jor .

and one minor casting defecc (sand inclusions) were decccced and re,..ixmt. . .o. . on cach o f tuo of the C O W i.. . . . .+. o. *- *

. .. a ~ JU;.d e d s free of defecca. W.c rept. e charts and inspeccion sign-off sheets indicate that, as required, radio-graphs were used to verify proper wcld repair after the first veld pass and half way through completed repair wcld in the case of the single major defect.

6. The purchase order called for, and inspection sign-off verified, welding activitics consistent with the requirements of ASM2,Section IX. , The records i also indicated that the veld rcpair work was performed in a conner consistent with ASME,Section III.

' Although the suction covers were made of austenctic secci,

\ 7.

outside storage was not a probicm because the covers were shipped from the plant floor one day after final acceptance by GE-Byron Jackson inspection personnel.

8. Records of wcld (fillcr) material control and usage were not available for review. Mr. Groshart explained

-that such records were not ge:. orated as far back as 1966. He added, however, that current QA-QC proceduros provide for "High Perfbrc.ance Product" processing and that the subject records would have been maintained for the suction covers under the current proccdurcs.

9. The available records estab11ched that the two suction covers requiring. weld repair were subject to post-wold heat creatment according to code requircconcs.
10. Radiographs were not availabic for revicw, due to the clapsed time since manufacture of the suctioa covers, but Mr. Zeiboll stated that the quality of ESCO radio-graphs is excellent.

E. Management Interview The inspectors met with Mr. Kirby and members of his staff along with the Westinghouse and PG&E representatives at che conclusion of the visit. Subsequent to an explanation of the responsibility of the regulatory arm of the Cor.. mission in connection with PG&E's proposed nuclear plant, a bricf summary was provided of the inspectors' activitics during the visit. Mr. Kirby stated that he welcomed the visit indicating that ESCO gains from such visits in that out-siders many times see deficiencies not apparent to personnel close to the operation. He added that ESCO had been in the business of supplying products for nuclear applications for '

about 15 years and that it was che company's intention to otay in the field.
