Licensee Action on Previously Identified Items
,
(Closed) Unresolved Item (329/80-01-07; 330/80-01-08); Inryco had not included complete calibration records for prestressing system jacks.
Inryco has now supplied the required calibration records for Prescon Jacks #1 and #3 and Dugdeon jack #'s 8780, 8778, 8783, and 8784.
In addition, Bechtel letter LAD-1551 states that the jacks are considered
"Q" equipment and records are required to be maintained in permanent QC files.
Spec C2-146, Section 12.1 has been revised to specify the jack calibration as "Q"~and records reviewed accordingly. This item is con-sidered closed.
(Closed) Unresolved Item (330/80-09-01); Tendon H-21-234 had 2 button-headed wires that had not seated upon restressing. NCR No. 2964 was issued and required the tendon to be removed and replaced.
It was veri-
'
fied that tendon H-21-234 had been replaced. This itom is considered closed.
(Closed) Unresolved Item (329/80-04-01; 330/80-04-01); Unit 2 pre-stressing system quality control records were found to be inaccurate.in a
number of cases where incorrect anchor head identification was noted and incorrect tendon elongation calculated. A review of the completed Unit 2 stressing cards was performed and correction has been completed. This item is considered closed.

Functional or Program Areas Inspected.
.
During this inspection,'the containment prestressing system procedures, work activities-and quality records were reviewed.
In addition, the
' inspectors attended a public meeting held at Consumers Power Company
,
offices in Midland, MI.
The ceeting concerned CPCo's appeal the NRC staff's request for additional soil borings in the plant fill and cooling lake dike. The appeal was made to the Director and Assistant Director of Engineering in the office of Nuclear Reactor Regulatory (NRR).

Containment Prestressing System
a.
Prestressing System Work Activities (Unit 1)
'
The inspector observed selected work activities relative to the tendon insertion and buttonheading on the Unit I contain-ment. The following specific items were observed:
(1) ' Tendon Insertion: Tendons V-34-1, V-107-1, V-105-1, V-28-1, V-83-1 and V-85-1 were observed being installed.
,
}
The tendons were in acceptable condition with n, signs or corrosion along the tendon lengths.
(2) Tendon Buttonheading - Tendon V-14-1 was observed
,
'
being buttonheaded in the Unit I tendon access tunnel.
Bechtel'QC inspector vas_present and was performing 100%
buttonhead inspection with calibrated GO-NO-GO gauge, dial indicator, and optical'comparator.
,
Tendon stressing and greasing operations were not in progress _
during the inspection.
b.
Prestressing System Material Records (Unit 1)
Material certification records f'or Unit I vertical tendons observed being installed were reviewed and compared to the material requirements of ASTMA-421 BA wire. The following
tendon records were reviewed:
V-84-1 thru V-89 V-80-1 thru V-83-1
.
V-107-1 thru V-110-1
The material records were found to be in accordance with requirements.

Review of Nonconformance Reports (Unit 1)
The following nonconformance reports were reviewed in order to verify adequate resolution of each identified deviation:

3100 Open nonconformance reports are to be reviewed during a sub-sequent inspection. The NCR's closed were identified and resolved in an acceptable manner.
d.
Stressing Sequence - Inryco drawing C-2-170, Revision 4b was reviewed.
It was noted that the stressing sequence has been modified a number of times to accommodate field installation due to availability of tendons. FSAR Section 3.8.1.6.3.2 states, "a detailted sequence of tensioning each tendon is developed by the tendon supplier". The prestressing system supplied *
land is Inryco. FCR 241' requrested engineering to revis
.ressing sequence.
Bec letter dated May 19, 1980 requ
.ed Inryco concurrence on the c ange.
Inryco re-m sponded on July 7, 1980 with acceptance of the revised sequence.
.
In addition, Bechtel had available the supporting documentation in evaluating the revised stressing sequence with reference to the original design guide, e.
Review of Quality Records (Units 1 and 2)
The inspector reviewed the quality records relative to contain-ment prestressing system for Units 1 and 2.
The records con-taine'd completed inspection report, tendon pulling card, button-heading card, stressing records and greasing card. The following specific records were reviewed:
(1) Unit 1 - Dome tendons D-301-1 thru D-306-1, D-201-1, D-202-1, D-309-1, D-311-1 and D-312-1.

(2) Unit 2 - Tendons D-212-2, D-209-2, V-74, 75, 82, 78, 79, and 109, V-80, V-85, and V-77.
The above records were complete and in satisfactory condition.
No items of noncompliance were identified in the above areas inspected.
2.
Meeting on Soils Issue at CPCo Office A meeting was held between Consumers Power Company and NRC staff on AuFust 29, 1980 to provide CPCo the opportunity to appeal to the NRC Division Director of Engineering a staff position requiring addi-tional exploration and testing of soils at the Midland plant site.
The CPCo consultants provided a statement to the NRC staff which indicated that further soil exploration would not be necessary since the engineering properties of the fill material have been identified since the surcharge in the Diesel generator building area. The NRC staff also made a presentation indicating the reasons for requesting the additional tests. After the two presentations were completed, the NRC Division Director indicated that a final decision would be made after the licensee submitted additional information that had not yet bebeen submitted to the NRC staff for review. This informa-tion would be made available by September 15, 1980 at which time a final decision regarding the licensee request not to take any addi-tional soil borings or tests would be made.
Exit Interview The inspectors met with licensee representatives (denoted in the Persons Contacted paragraph) at various times during their inspection activities.
The scope and purpose of the inspections aere outlined along with the findings of the inspection. The licensee representatives acknowledged the indicated results.
