Exit Interview
The inspection scope and findings were summarized on May 10, 1979, with
those persons indicated in Paragraph 1 above .. The items of noncompliance
described in paragraph numbers 6(i) and 6(k) were discussed in detail. The
inspector indicated that there would be three items of noncompliance. Upon
discussion with regional office supervision, it was decided that two items
would be cited.
VEPCO was informed .via the resident inspector on May 16,
1979.

Independent Inspection Effort
a.
The inspector conducted a general inspection of the auxiliary building,
the containment, the refurbishment building and the fuel building to
observe construction progress and construction activities such as
steam generator lifting, tilting, and removal, weld joint preparation,
radiation control, washdown of new fuel, material handling and control,
housekeeping and storage.
b.
The inspector witnessed the radiographic examination, in accordance
with ASME Section III and V, 1974 Edition with Addenda through Winter
1976, of Weld No. 1 on ISO ETA 40007-3-U2B.
The inspector observed
setup and exposure activities to determine if the code requirements
were being met. Areas being reviewed included minimum source to film
distance, type and thickness of intensifying screens, use of location
markers, selection and use of penetrometers and base material and weld
surface condition.
c.
(Closed) Inspection Followup Item 50-281/79-23-01. This item concerned
a nonessential variable (contact tip to work distance) that had not
been covered in Technique Sheet 8-8-D-13 of DCC Welding Procedure 8-8
Revision 2, as required by ASME Section IX.
The inspector verified
that the above procedure Technique Sheet has been revised to include
the variable in question.
No items of noncompliance or deviations were identified.
6.
Steam Generator Replacement Observation of Welding and Associated Activities
The applicable code as required by "VEPCO' s licensee submittal (Steam
Generator Project Surry Power Station Unit Nos. 1 and 2, Revision 9)," is
ASME Section XI, 1974 Edition with Addenda through the Winter of 1976.
Based on paragraph IWA-7000 of section XI, VEPCO is ti.sing the original
construction code (USAS B31.1.0-1967) for pipe welding. Welder qualifica-
tions and procedure qualifications are being performed in accordance with
the latest edition and addenda of ASME section IX in effect at the time of
the qualification. All welding materials were purchased and certified in
accordance with Class I requirements of the ASME code.
In connection with completed Weld No. 1 on ISO ETA 40007-3-U2B prior to
final NDE the inspector observed activities and facilities in the level A
and B warehouse, and welding material control issue stations and reviewed
the Quality Control Manual, w~lding procedures, and selected procurement,
certification, inspection, qualificatlon and issue records to complete the
following inspections.
a.
The inspector verified that welding personnel were qualified by DCC in
accordance with the requirements of ASME Section IX and additional
requirements of ASME Section XI.
..
b.

-3-
The inspector verified that new base material and welding filler
materials were certified to meet code and other specification require-
ments.
c.
The inspector reviewed receiving records and certifications to assure
that consumable inserts, bare wire and coated electrodes for manual
welding met the applicable code.
d.
The inspector verified that suitable facilities were provided and
maintained for storage of electrodes, flux and other materials for DCC
and VEPCO.
e.
The inspector verified that dispensing of electrodes was controlled by
DCC so that no mixups could occur and exposure of unused electrodes to
moisture pickup is minimized.
f.
The inspector verified that unused welding filler material was returned
and properly dispositioned to either holding or drying ovens.
The
inspector further verified that damaged electrodes and stubs were
scrapped and removed in containers from the work area at the end of
each shift. The above was verified for DCC only.
g.
The inspector verified, for DCC only, that dispensing of weld filler
materials was done only by withdrawal forms, which identify the type
and quantity of material.
The inspector further verified that the
welder was identified on this form and that an authorizing signature
is required.
h.
The inspector verified the existance of an adequate DCC procedure for
the identification and resolution of defects disclosed by NDE methods.
i.
As required by Criterion V of Appendix B to 10 CFR 50 and as implemented
by VEPCO Topical Report VEP-1-A, amendment three, paragraph 17.2.5,
requires that activities affecting quality shall be prescribed by
documented procedures, and shall be accomplished in accordance with
these procedures.
Daniel Construction Company Construction Procedure
(DCC-CP) WP-502, Revision 1, "Control of Welding Filler Material",
requires that field electrode control station attendants attach a
sketch to the front of each electrode holding oven specifying the
size, class, lot and location of the covered electrodes in that oven.
Further DCC-CP WP-502 Revision 1 requires field. electrode control
stations to be securred to prevent unauthorized access.
Contrary to the above, the following examples were observed:
1.
On May 8, 1979 the sketch on the electrode holding oven in the
refurbishment building contained an incorrect lot number.
For
Lot No. 02*2-B905R, 1/8 inch diameter type E-7018 electrodes, the
first diget was erroneously entered as 9 vice 0. This error was
prepogated to eight "Field Requisition - Welding Materials" W-100
forms.

-4-
On May 10, 1979 the key to the above locked oven was in the
possession of an individual not authorized by DCC-CP-WP-502 to
possess the key.
On May 10, 1979 the electrode location and identification sketch
for the above oven reflected no electrodes on the center shelf
when in fact the center shelf contained electrodes.
This is an infraction and is identified by noncompliance number
281/79-33-01.
j.
The following corrective actions for noncompliance identified in
paragraph 6(i) above were verified by the inspector:
1.
Investigation revealed there to be only one lot of 1/8 inch
diameter type E-7018 electrodes on the site. In view of this
fact, the eight "W-100" forms and the sketch were corrected.
2.
DCC put the electrode holding oven key into the hands of a properly
authorized individual.
3.
It was determined, by printed control numbers on each electrode,
that the electrodes on the center shelf of the holding oven were
of the same lot as the lower shelf. in view of this fact, the
location sketch was corrected to reflect the true oven contents.
k.
As required by Criterion XVII of 10 CFR SO, and as implemented by
VEPCO Topical Report VEP-1-A, amendment three paragraph 17.2.17, that
requires sufficient records shall be maintained to furnish evidence of
activities affecting quality and that these records include results of
inspections.
Contrary to the above, on May 8, 1979, five "Receipt inspiction Report"
forms had the following boxes not marked:
"No Shipping Damage",
"Properly Packaged", "Cleanliness Satisfactory", and "Properly Identified".
These reports were found in the following purchase order files:
SGR-12188, SGR-12391, and SGR-12609.
This is a deficiency and is identified by noncompliance number 281/79-
33-02 .
