SUMMARY
-
Inspection on January 9-11, 1979 Areas Inspected This routine unannounced inspection involved 17 inspector-hours onsite in the areas of Category I structures and supports outside the containments; containment penetrations; main steam line relief valve assembly for Unit 1; and the standby nuclear service water dam.
.
Results Of the four areas inspected, no apparent items of noncompliance or deviations were identified.

Independent Inspection Effort (a) A follow on inspection of the standby nuclear service water dam was made in company with the essigned civil engineer.
Erosion control on the downstream face of the dam was found to be adequate.
Effluent water from seepage draws was clear and appeared to be flowing at a steady rate of about 15 gallons per minute.
No settlement or realignment of the embankment had been recorded.
(b) The main steam line relief valve assembly for Unit 1, outside the containment, was examined for measures designed to resist reactive forces from steam discharge.
It was determined that adequate restraints had been installed to protect the assembl..

Safety Related Structures (Structural Steel and Supports II) - Observation of Work and Work Activities Units 1 and 2 McGuire structures in this category are limited and have been completed.
The inspector chose to inspect for both units the reinforced concrete base of the reactor refueling water storage tank, the concrete base of the reactor makeup water storage tank, and the structural steel supports for the main steam lines adjacent to the containment and those on the roof of the auxiliary building. A visual inspection was made, controlling documents were reviewed and quality records were reviewed for the completed work.
The controlling documents included:
a.
Drawing No. MC-1385-01, Revision 15, " Misc. Yard Structures, Reactor Refueling Water Storage Tank Foundation, Reactor Makeup Water Storage Tank Foundation, Concrete and Reinforcement".

Safety Related Structures (Structural Steel and Supports 1) - Review of Quality Records for Unit I and Safety Related Structures (Structural Steel and Supports II) - Review of Quality Records for Units 1 and 2 After referring to the documentation requirerents of the controlling documents listed in paragraph 6, the inspector reviewed quality records including:
a.
Prepour site inspection reports for the reactor refueling water storage tanks and the makeup water storage tank.; for Units 1 and 2, for inspections made in April, August and September of 1974.
b.
Structural Steel Erection Inspection Report Form 18A, dated March 25, 1977, for two Supports, Mark

"E",
and five supports, Mark "F", at elevation 784
'+0" on roofs of auxiliary buildings for Units 1 and 2.
The records review identified no nonconformances or deviations.

Containment (Penetrations) - Observation of Work and Work Activities (Unit 1)
Unit 1 control was transferred from Duke Construction to Duke Power Production (Operations) Control in 1976. Unit I was under systems hot fuctional test during this inspection.
Inspections of containment penetrations were made by AEC-NRC inspectors and reported in 1974 and 1976.
During this follow-on inspection the inspector made a visual inspection of the main steam line penetrations and the completed equipment hatch which was installed after the construction block out of the liner was closed.
Design and quality requirements for the liner and its penetrations were stipulated in Section 3 and 17 of the PSAR. These were supplemented by
,
requirements shown on the procurement specifications and drawings, the fabricator's detail drawings and the electrical penetration supplier's documents. These documents included:
a.

From observation of completed work and review of NRC and Duke documents the inspector cor.cluded that adequate controls had been imposed on installation of penetrations.
No noncompliances or deviations were identified during this follow on inspection.

Containment (Penetrations) - Observation of Work and Work Activities Unit 2 Two inspections of penetration installation work were made by NRC (AEC)
in 1974. Activity on this unit has been resumed after long interruption.
This follow on inspection involved observation of the work of installation of containment liner plates, with circular cut out, in the construction
