Licensee Action on Previous Inspection Findings (Unit 2)
(Closed) Deficiency (370/80-08-03) Failure of Ultrasonic procedures to provide adequate instructions for performing and recording examinations.
Duke Power Company's letter dated August 7, 1980, advised Region II of corrective actions taken. The response is satisfactory and actions have been taken. The inspector reviewed the revised procedures and considers the corrective actions taken to be satisfactory.
(Closed) Unresolved Item (370/80-12-02) Potential inadequate magnetic particle examination.
The individual involved in the unsatisfactory exam-ination was disqualified and re-trained.
The welds involved were. rein-spected by qualified examiners.
In addition, several previous welds, examined by the disqualified individual, were re-examined and found to be satisfactory.
The corrective actions taken are considered to be satisfac-tory.

(Closed) Violation (370/81-02-01) Failure to establish adequate controls for storage of installed equipment. Duke Power Company's letter dated May 12, 1981, advised Region II of corrective actions taken.
The responsa is satisfactory and actions have been taken.
Construction Procedure 861 was i
issued to provide controls concerning installed equipment.
The inspector reviewed this procedure and toured the plant for evidence of enforcement.
No violations were noted. Corrective actions taken are considered to be satisfactory.
(Closed) Unresolved Item (370/81-02-03) Temperature Control of Baking Oven.
The rebaking ovens, that operate at 725 F, now have two independent thermom-eters which provide redundant measurements. All of the portable thermome-
!
ters used in the holding ovens were placed inside one oven and checked for equal measurements.
One thermometer was discarded, others were satis-factory. Corrective actions taken are considered satisfactory.
(
(Closed) Unresolved Item (370/81-02-04) Extraneous markings on safety-
related stainless steel.
The subject marking materials were tested for contaminants and found to be chemically acceptable. The licensee has also
,
l started a program which is intended to eliminate unnecessary markings.
Corrective actions taken are considered satisfactory.
(Closed) Unresolved Item (370/81-06-01) Base metal and adjacent weld defects
'
on radiographic films were not evaluated. The licensee physically sighted several of the components and found that the subject defects had been removed / repaired. Those that could not be sighted were re-evaluated on the i
films and were determined to not affect the integrity of the component.
Penetration 2M262 was evaluated, assuming cracks may exist, and determined by Design Engineering to be acceptable as is. (See memo to file, MG-81-277, dated 6/18/81).
The radiographic records, in each case, were annotated (
accordingly to address the subject defects.
The corrective actions taken are considered satisfactory.
(Closed), Unresolved Item (370/81-06-02), QA records not available for containment penetration alignment.
The inspector reviewed records 'for l
penetration E103 which verified alignment, however, no QA records could be located for access penetration C-152. ~ The licensee stated that alignment.of
!
this penetration can be established by the fact the closure functions properly. The actions taken are considered satisfactory.
l (Closed) Unresolved Item (370/80-08-02) Inadequate certification of visual l
examiners. The inspector reviewed the revised visual examination procedure (ISI-350 Rev.12) and the training program and considers the corrective actions taken to be satisfactory.
y (Closed) I.nfraction (370/80-12-01) Inadequate training / qualification of visual examiners. Part of this infraction was reviewed during a previous i
'
inspection (See report 81-06).
The inspector reviewed the test specimens used for training and qualification and also the practical examination requirements. Corrective actions taken are considered to be satisfactory.

Preservice Inspection-Observation of Liquid Penetrant Examination (Unit 2)
i No preservice inspections were performed at McGuire, Unit 2, during this inspection.
The inspector reauested the B&W baseline coordinator to schedule a liquid penetrant examination at the Catawba site on June 19, 1981, during the inspector's visit there. This was done and the inspector observed a baseline liquid penetrant examination of a 4-inch diameter safety-related pipe weld. (See Catawba report 81-13).
No violations or deviations were noted.
8.
Inspector Followup Items (Unit 2)
(Closed) Inspector Followup Item 370/81-02-05, Non-Retrievable NDE Personnel j
Records.
The licensee presented the inspector with appropriate personnel records for review. The records were satisfactory.
l (Closed) Inspector Followup Item 370/81-06-03, Records for administering and for limitations concerning visual acuity are incomplete.
The licensee
modified their reporting form which now requires annotation as to whether corrective lens are required or not. Also, all NDE personnel are being re-examined for visual acuity by a registered nurse. About one-half of the re examinations were complete during this inspection.
Corrective actions
taken are considered to be satisfactory.

Licensee Identified Items [50.55(e)] (Unit 1)
'
(Closed) Item 369/80-10-01, Socket welds do not meet applicable quality
,
standards.
On April 3, 1980, Duke notified Region II of a 50.55(e) item concerning under size socket welds.
The final Construction Deficiency i
Report was submitted on May 2, 1980. The report was reviewed by Region II in February 1981 (See report 81-02) and determined to be unsatisfactory.
The licensee has subsequently conducted a deeper investigation of Unit 1 socket welds and concluded that the small percentage (less than 2%) of under size socke ts in Unit 1 does not warrant any furthe rwork. All under size sockets were in pipe less than 2-inch diameter and were re-welded to provide sufficient weld size. The licensee also advised that the same weld proce-dure was used on all Unit I socket welds, thus supporting their position that the percentage of under size sockets not measured would be less that 2 percent, and those would only be very slightly under size based on the ones detemrined to be under size. Ths corrective actions taken are considered to be satisfactory.
