Independent Inspection
a.
The inspector conducted' general inspections of the reactor and auxiliary
~
buildings to observe activities such as housekeeping, material handling, material storage and protection of installed equipment and components.
'
These inspections were conducted on at at least a daily basis during -
the time of *he inspection with additional inspections on the evening shift.
,
b.
The inspector observed the sampling and testing of concrete during.
Pour No. 4543, for wall W206A. The tests witnessed were the concrete
'
temperature, slump, and air content tests for the _ pour. The' tests
!
were conducted at the location where the concrete was being discharged
)
from the trucks to the crane bucket.
'
.
c.
The inspector conducted an inspection of the piping material storage yard and warehouse.

Reactor Coolant Pressure Boundary (RCPB) Piping The inspector observed work and work activities in the area of RCPB piping in both units. The observations included the following:
a.
(Unit 1) The inspector selected installed RCPB piping pieces No.
-
INC-44-EE and INC-46-EE to verify that they were installed in accor-dance with applicable design requirements.
The piping selected was between two primary loop hot legs and a "T" connector leading to the pressurizer spray piping connection. The installed piping was compared with the isometric drawings; design drawing Nos. CN-1491-NC017 and CN-1491-NC018; and flow diagram CN-1553-1.1 Rev.
4, Chg.
4., as well as the control valve specification No. 1205.06-03, b.
(Unit 2) The inspector observed preparations for the fit-up of the primary loop hot legs (between reactor vessel and steam generator).
Temporary support and protection of the hot leg piping pieces and the protection of the steam generator and reactor vessel nozzle weld preps were inspected.
There were no items of noncompliance or deviations in this area of the inspection.
7.
Safety Related Piping (Unit 1)
The inspector observed the weld repair activities on 8-inch diameter by
.322-inch nominal wall, containment spray piping weld joint No. CN-INS-114, repair 2.
The repair was to correct a lack-of-fusion, lack-of penetration reject requiring a grind-out completely through the weld joint and the use of the "open-butt" welding technique to complete the we]d repair.
While the inspector was observing the welder's repair activities he also observed the licensee's inspectors verifying wall thickness measurements adjacent to several containment spray piping welds using ultrasonic techniques.
There were no items of noncompliance or deviatrons in this area of the inspection.
8.
Containment Structural Steel (Unit 2)
The inspector observed welding of the following three welds in the Unit 2 containment dome:
Weld P-5-5-B (Horizontal)
Weld P-5-16-B (Horizontal)
Weld P-5-17-R (Vertical)
The fit up and preparation for welding of several other veld seams in the areas adjacent to the welds mentioned above were also observed.
There were no items of noncompliance or deviations in this area of the
' inspection.
