2 Deviations:
(1) Training - contrary to EAP 2.4 experience recorus of Structural Division personnel did not contain information on their continufag education activities (See Notice of Deviation, Enclosure Item A).
(2) Srpplier Non-conformance and Corrective Action - contrary to EAP 2.10, changes to activities specified in a PSAR were made without the required documentation and review of these changes (See Notice of Deviation, Enclosure Item B). (3) Supplier Non-conformance and Corrective Action - contrary to QS-15.1, there was no indication on N&D #0121 that it had been closed out, but the equipment had been shipped and some had been installed (See Notice of Deviation, Enclosure Item C).

In this area of the inspection, two deviations were identified (See Notice of Deviation enclosure, Items B and C). No un-resolved items were identified.
b.
Concerning Notice of Deviation Item B, partial corrective action was accomplished during the course of this inspection by Stone and Webster in that a Licensing Document Change Request was initiated on 8/23/79 "to revise PSAR section 17.1.B in its entirety to reflect the Project QA manager, Quality organization as well as the S&W Quality Standards Procedural System." This requested change has been evaluated as " Substantial" by S&W on the licensing Document Change Request Form and in-house reviews of the changes will now be conducted. Note that S&W had previously submitted a change notice to PSAR Section 17.1.B.
which was withdrawn (voided) before S&W in-house review was

Nondestructive Examination (NDE) of Flued Head Penetration Welds 1.
Objective The objective of this area of the inspection was to determine the background and current status of the problem concerning the NDE of a weld by Graver (Graver Tank and Manufacturing Company) that joins the flued head forging to the sleeve on the flued head type contain-ment penetrations.
2.
Method of Accomplishment The preceding objective was accomplished by review of the following documentc:
a.
For Job No. 12210, Specification No. 219.710 (Revision 2, August 7,1978), " Shop Fabrication and Field Erection of Reactor Containment Vessel...," including penetrations.

S&W audits of Graver dated October 20, 1978, and December 18, 1978.

16 h.
The following interoffice memos (IOM):
(1) Minutes of Task Force meeting on UT aadit findings at Graver dated March 16, 1979.
(2) UT Task Force Summaries dated May 30, 1979, and June 19, 1979.
(3) CR-50444, Report of a S&W Problem, dated May 3, 1979.
(4) Radiographic vs Ultrasonic Examination of Penetration Flued Head Forging Welds, dated April 12, 1979.
3.
Findings a.
Specification Nos. 219.710 and P283B were issued to Graver and required UT examination of the subject welds; however, Addendum 1 reissued Specification No. P283B to Chicago Bridge and Iron after Niagara Mohawk cancelled its contract with Graver.
b.
S&W audits of Graver identified numerous areas where UT of welds were not properly performed resulting in rejectable indica-tions not being identified. Some of these incorrect UT methods may have occurred as early as July 1978 according to these audits, and included %e subject welds.
c.
An S&W task force was formed to study the UT problems identified in the audits of Graver as well as any other NDE problems.
Through the task force efforts, and subsequent to a NRC site 1
inspection in March 1979, a draft Problem Report was issned, IOM CR-50444. This report was distributed to all S&W projects (past and current) with the instruction to review immediately f
and initiate corrective action where similar design or equipment /
material conditions exist concerning NDE of penetration flued head forging welds. The following interim conclusions and recommendations were made: (1) UT for the subject weld joint is not considered the code acceptable examination; (2) the applicable specifications for Job Nos.12177 and 12210 be changed from UT to RT for the subject welds; and (3) all inprocess UT should be stopped and UT already completed should be handled as unsatisfactory and re-examined by RT. The conclusions and recommendations in this draft Problem Report are considered by S&W personnel as interim and preliminary. The final S&W position on this problem in still being developed.
d.
S&W issued E&DCR Nos. P-M-(G)-144 and P10727 which revised Specification Nos. 219.710 and P283B to require RT instead of UT for the subject welds.
\\
)
17 e.
The S&W task force is continuing their study of this UT problem with further meetings with NRC site inspection per-sonnel in the near future.
f.
No deviations or unresolved items were identified in this area of the inspection.
