RIS?ONSI TO VIOLATION Thc'rcuponse'co this violscion is addresund in two s,ups:s:e r s parts:

if .

(I 1. Radiography Before Te=pering:

The valve supplier's ande licensee's interpreta: ion of the code requirement for the timing of radiography is: The March -

1970 Addendum of the-Draft Pu=p and valve Code allows radiog-raphy to be_perfor=ed a: 'any. cine. Paragraph 615.3(b) s:stes:

" Radiographic,, ultrasonic and addy cur:en: examinations _ may be performed before or after any forming or hea trea: ment." .Also, Seccion 314 of-the 1968 Draft AS3E Code for Pu=ps and Valves'for Nuclear Power requires cha:'"non-' dest.uctive exn=inacions for ma:erials shall be performed after any heat treatments'. required

'by the Material Specificacion". The Material Specification for the MSIV's (ASTM A216-69) requires tha: the ma:erials be , _

either normalized or normalized and tempered.

Thus, the D sfc Pu=p and Valve Code is in=arp;c:od for ASTM .

A216-69 to mean: "non-destrue:ive exs=ina: ions for =a:erials s shall be performed after normalizing'or normalising and ce:pering." l

- This interpreta

ion is considered as' good engineering' practice because :empering would not cause any change or itow:h of

2. 'Pos: Weld Hos: T cacment At 1340 deg ce 7:

Weld Procedure QAP-49D, da:ed May 7, 1971 was used for-repair welds on MSIV 3227022D. However, in March of 1973, Phila-dalphis.Elce::ic Co=pany identified a noncompliance to :his procedure during a. source audit: weld repairs'in excess of the-qualified size range were made. . Corrective action to this finding was to modify,the procedure. Previous to this finding, a qualification of this procedure was performed and a'PQR:exis:ed

. for the larger velds.- The modified procedure was back dated October'26,.1971 to =atch tha date of che PQR. The October 26,

-1971 procedure was submi:ced as part of the final documentation

- package'for the valve and therefore this was the procedure used in reviewing the final records.

QAP-49D dated Occober 26, 1971-did not limit post vuld huac creatment temperatures.. In addition, the DCPV did not lisit the r/ .

emperatures as do more_ current editions of the Code. (Section

-\ ~ IIT scarced in 1973 to li=it PWMT comperneures to 1250 degroo 7 fi

%- for carbon stec1). f.ls o , Succion IX of.che Code was a=higuous-in regard to wha: change in heat treatman: temperatures cons:1:u:ed the need for procedure requalification. However,,recen: editions' of Section IX have cleared the ambiguicy. In. view cf the curren:

'+ . iacurpretaciuu..wu are in the process of qualifying the veld procedure for the post veld heat.crea: men: - compara:ures used.

1 We expect to have the qualification tes:s complaced and evalua:ed i L'y May 31, 1982.

+.

We have reviewed the docu=enta:$on of several other icens supplied g< by the sa=a foundry and samples of other. suppliers and have

! determined that the high post veld heac creat=ent temperaturer are-

!' isola:ed to the MSIV's. Also, since 1973 the Code has limi:ed I post' weld heat creatman: temperatures. Therefore, other than L' the above described actions, no additional ac: ion :o* preven:

l recurrence is needed.

Responso to Violation Eachtel Power Corpora:1on'NCR 5353 was. written reporting that the prehea: had no: boon verified on Quality Control Inspection Record C-1415-W-1. The NCR has been disposicioned by Bechtel design engineers to "use-as-is". The':stionale for this decision is : hat the prehea: . requirements for these welds are to prehea: to 70 degree F'if'the ambione compara:urauis below 32 degree F. The subject welds
