2 Unresolved Items: Nonconformances and Corrective Action; the Requests for Corrective Action documents were not generated by the Superintendent of Inspection based on a review of Nonconformance Reports, as described in the QA Manual.

(See Details Section, paragraph D.3.b).

3 DETAILS SECTION A.

Persons Contacted W. Barrett, Superintendent of Inspection P. Butler, NDE Engineer D. Carson, Welding Foreman

  • W. Davis, Supervisor, Welding Engineering S. Grimm, Welder L. Hayden, Vice President of Engineering E. Massey, Welder
  • J. Seay, Manager of Quality Control W.

Irent, Metallurgist

  • S. Vitatoe, Section Manager, Quality Process Engineering
  • Attended the exit meeting.

B.

Action on The Previous Inspection Findings (Closed) Deviation B (Report 78-02):

Failure to provide documented measures to calibrate the weld shielding gas flowmeters on welding machines numbers 32132, 32048, 32108 and others.

The inspector found that ASME Code Interpretation III-1-78-213, "Section III, Division 1, Calibration of Welding Machines and Gas Flow Regulators" originally issued July 21, 1978, had a clarification issued on April 20, 1979, which states, " Manual and semi-automatic welding equipment, as de-fined by Section IX, including auxil3ary 2quipment, such as gas flow regulators are not required by NCA-4134.12 to be calibrated." In consid-eration of this and other related circumstances, the above matter is no longer considered a deviation.

However, although Tube Turns' letter commitments to the NRC, dated February 27, 1979, to initiate calibration of the flow =eters no longer appears necessary, a written withdrawal of this commitment is needed.

Tube Turns' Manager of quality control indicated that he will issue the necessary letter to the NRC.

C.

Continuing Followup on Part 21 Report Dated April 12, 1979

==

Introduction:==

This Part 21 Report involved incorrect pipe fitting ma-terial included in fittings marked lot W6719 which were supplied by the Tube Turns Louisville Plant during the period of March, 1978 to March, 1979 to various distributors for use in both nuclear power generating plants and non-nuclear use.

Tube Turns reported this matter to the liRC by letter dated April 12, 1979, and an NRC followup inspection was per-formed in May, 1979.

(See Report No. 99900028/19-01)

Tube Turns imple-mented a corrective action recall program to account for all of the W6719 fittings including those for use at nuclear power generating site.

The recall program was in process during the May, 1979 NRC inspection.

1.

Objective The objective of this inspection was to review the status of the recall program relative to those W6719 fittings which were supplied for use in nuclear sites.

2.

Method of Accomplishment The preceding objective was accomplished by discussions with Tube Turns QA consultant and review of a process recall recorda.

3.

Findings The part of the recall program dealing with '.6719 fittings supplied for use in nuclear sites is nearly complete.

The list of nuclear sites to which the W6719 fittings were shipped now identifies more sites than were identified in Tube Turns letter dated May 10, 1979, to the NRC.

The NRC inspector recommended to the Manager of Quality Control that he submit an interum or final report, including a new list of affected nuclear sites, to the NRC when Tube Turns is assured that all of the W6719 fittings shipped to nuclear sites have been accounted for.

==

Introduction:==

The Tube Turns Division of Chemetron plant management located in Louisville, Kentucky, called the NRC Region II assigned in-spector on June 5, 1979, and then submitted a 10 CF" Part 21 Report, dated June 7, 1979, to NRC Region II regarding a certain sleeve to con-tainment liner insert weld in fif teen (15) subassembly sleeve penetra-tions, wherein the welds had not received a required stress relief heat treatment.

These subassembly sleeves had been shipped to Carolina Power and Light Company for use in the Shearon Harris Nuclear Generating Station.

Tube Turns initiated corrective action through the purchaser, Ebas co Services, to have all fif teen (15) subassemblies returned to the Louis-ville plant for stress relieving.

Ebasco, the Architest.-Engineer, and the Owner, Carolina Power and Light, were made aware of th< conditions.

Tube Turns also reported by letter dated June 21, 1979, to NRC Region II that their Engineering Departmen'. had reviewed all orders for nuclear power plant f abrications and der armined that, other than ene shearon Harris unit, only one assembly had bee? made that included part of tae containment liner, and they had confirmed that the subj ect weld was stress relieved.

Carolina Power and Light also reported this deficiency to NRC Region II, by letter dated August 3, 1979, with attached Final Report, as a 10 CFR 50.55(e) construction deficiency.
