Requirments ASME Section IX for procedure and performance qualifications was reviewed for the essential variables applicable to E-309
& E-308.
These variables include:
QW-404.4:"A change from one F-number in QW 432 to any other F-number or any other filler not listed in QW-432" I :
(ie E308 & E309 are ASME SFAS.4, FS, A8.)

XX-85-013-001 DETAILS, continued QW-404.5:"For the ferrous materials in QW 422 a change in the chemical composition of the weld deposit from one A-number to any other A-number in QW-422."
(ie-E308 & E309 are ASME SFA 5.4,F5,A8) i Either filler material is acceptable.
1 ASME Section II,Part C-Filler Metal states:
l "SFA 5.4 "E309,
- E309cb, E309mo, all have a
tensile strength min. PSI of 80,000".
l SFA-5.4's Identical with the requirements of AWS AS.4 69 ASME Section II Part A-Material Specifications states for SA-312 TP316L min. tensile strength shall be 70,000 psi.
Therefore the filler metal is 2:
70,000 i
PSI required for the base material.
[
(ffj SA-312 TP316 L is designated P-8 material.
FINDINGS:
?
Based on the review of the ASME code requirements and the
][
applicable documentation and procedures, the following is determined:
s L
E309 filler metal (electrode) is compatable to the A&F
(
number designations for E308 and E309.
1 s
For the base material, there is no essential variable violation to the code and is allowed per applicable Weld Procedure Specification / Procedure /Preformance f
Qualification Record.

]
Based on the findings in this investigation a change from E308 to E309 (same A&F designation) is not a violation of the code or procedure.
The concern as stated may be true.
d
- However, the change from 308 to 309 filler metal has no 4
impact on weld quality.
This concern is closed.

This package cummarizec the actions taken by the Welding Project (WP) to evaluate and dinposition the subject. SON-specific employee concern which was Lj previously evaluated by NSRS/DTC/ERT and summarized in Wo Phase I and Phase II f.
reports.
j ild h
The Welding Project analy:ed each SON-specific employee concern (Attachment 2) to determine the statement (s) being voiced by these individuals.
i b
These statement were then evaluated both individually and collectively to J
develop issues.
1 i l 4
Each issue was then incorportated into the WP review activities of Phase I, 1
"P ocedural Assessment" and Phase II, " Procedural Implementation."
During Phase I, each issue was analy:ed against requirements of the applicable l
OA program, policies, NSRS/OTC/ERT Investigation Reports, and other relevant 1
l i
information to determine if program elements were deficient when evaluated y$
j, against upper tier requirements.
Phase II consisted of a sample reinspection of hardware and independent 2
4 k' ;i program audit by Bechtel.
J f..
In each area analy:ed by Bechtel, the auditors found no objective evidence to I
I
{.
substantiate the employee concerns considered. The following areas directly 9
a l[
related to employee concern were investigated by the audit team:
O Vp 07I Page 1 of 3 w., =4 I e 1 l t I h
1. Welder qualification and attendant records \\ 2. Welder qualification and attendant on-the-job-training 3. Welding inspections 4. Welding inspectors training programs 5. Weld material traceability 6. Welding inspections by craft personnel 7. Weld material control Each of these areas was investigated by the auditors for both construction and operations phases. In all cases, there was no objective evidence to substantiate the employee concerns. The audit report concludes that both construction and operations phases have had and now have a functioning Welding Quality Assurance Program which meets code, standard, and regulatory requirements and that the employee concerns considered were found to be unsubstantiated and without technical merit. Pago 2 of 3 03371
(( The results of the reinspection program at SQN also give another, additional verification of the Welding Quality Assurance Program for both construction and operations phases and serve to establish additional confidence in the accuracy and implementation of these programs through hardware inspections and attendant document reviews. In all cases, the components and items were found to be acceptable upon initial reinspection or found to be acceptable after engincoring analysis. The WP analysis of SQN Specific Employee Concerns supplemented by the independent Bechtel Audit, reinspection of installed components and systems, and independent (NSRS) overview and investigations has not revealed any significant or generic inadequacies in the welding programs for either the construction or operations phase at SQN which have been directly identified [j!; through the Employee Concern Program. The Employee Concern Program has simply w reiterated problems which have been or are now being resolved through existing corrective action programs in the overall Nuclear Quality Assurance Program. A summary analysis of the WP evaluations and recommendations is included in. Page 3 of 3 337 Page 1 of 3
