Exit Interview j
The-inspector met with the licensee representatives noted in paragraph 1 L
above on January 17, 1980, at the conclusion of the inspection'of steel structure and. support welding, safety related pipe welding, and Anchor Darling Valve. _Dirposition of the NT indicationsLin the Anchor Darling
' Valve was discusse3. The inspector stated that further guidance relative to disposition of the indications would be' furnished later and the matter
[would be identifird as an -inspector' followup item (see paragraph 5.c.).

Independent Inspection Effort (Units A1, A2 and B1)
The following areas were examined by the inspector.
a.
A general site inspection was made and general construction activities
,
and conditions observed in the following areas:
Reactor building (Units Al and A2)
-
Auxiliary building (Units Al and A2)
Steam Fitters Shop No. 1
,.
b.
The inspector observed in-process safety-related pipe welding in the number 1 steam fitter shop. The welding is being accomplished In accordance with the ASME Boiler and Pressure Vessel Code,Section III, 1974 Edition includir.g the 1974 Summer addenda. Welds A1AES0020001E, A1AES0020001A and A1AES0020001B were observed during fitup, fitup
inspection, and welding of root pass. Fitup, inspection techniques, weld appearance, welder qualification, use of correct weld procedure, use of correct filler material, and filler material control were examined.
_
c.
Eased on a request from IE-RIV, relative to an inspection problem in
'
the Anchor Darling Valve Company (ADW), the inspector requested the licensee to magnetic particle (MT) inspect the body of ADW Valve
,
serial E-6318-40-8.
The valve is a Class 2, 18" diameter, 300 psi globe valve assigned to Unit 1 of plant B (MPL # E12-F-048B). The inspector witnessed the MT inspection, reviewed the certification package for the valve and made the following observations:
r l-(1) The licensee performed 100% MT inspection of the outside surface of the body using the DC-prod method. Twenty-two linear indica-tions were found scattered over the body ranging in length up to 1 1/4".
Some of the indications were checked with the AC-Yoke and were found as readily as with the DC-Prods.
.
[,
(2) Review of the certification package revealed the following relative

Steel Structures and Supports - Visual Examination of Welds (Unit A1)
r Ths inspector visually examined and reviewed quality records for completed
-
structural field welds as described below to determine if applicable code
'
and procedure requirements were being met.
See paragraph 6 above for the applicable code.
.
a.
The following welds were visually examined relative to:
location, i
length, size and shape; surface finish and appearance including grinding and surface thinning; reinforcement; removal of temporary
,
t attachments; and surface defects:
Pedestal Weld AIPED0004 I'
-
Pedestal Weld AIPED0002 i
Containment Shell Weld AICS00332 Containment Shell Weld AICS00333 b.
Quality records for the following welds were reviewed to determine whether:
(1) the records covering visual and dimensional inspections
indicated that the specified inspections were completed, (2) records reflected adequate weld quality, and (3) weld history records were
'
adequate:
Containment Weld AICS00333 Containment Weld A1CS00332
,
In addition to weld history records, the inspector reviewed the-radiographic film for the above.two welds.
Within the areas inspected, no items of. noncompliance or deviations were identified.
