a EV ALUATION OF THE THIRD YEAR INSERVICE TENDON SURVEILLANCE FOR THE CALLAWAY NUCLEAR PLANT l
The Callaway Plant Technical Specification 4.6.1.6.1 requires the demonstration of containment structual integrity through a surveillance of the containment post-tensioning system at the end of 1 5, 3 5, and 5.5 years following the initial structural integrity test, and every 5 years after. During the l
surveillance of the system af ter 3 5 years, which began July 6,1987, it was discovered that the net refill volume of the sheathing filler material exceedad 5%
l of the net duct volume for surveillance tendons V18, SAC,11CB, 14BA, 18BA, and l
l 35BA (see Attachment 1, Tendon Greasing Summary). This void condition failed to meet Tech. Spec. 4.6.1.6.1(e) which requires verification of operability of the sheathing filler material by assuring "(1) No voids in excess of 5% of the net
-l duct volume". Due to the fact that a void greater than 5% was discovered after filling, action statement 3 6.1.6.B was immediately satisfied. The NRC Staff concurred with this position in a meeting on the same subject for the first year surveillance on. July 19, 1985.
The Callaway containment building is a post-tensioned, reinforced concrete structure comprised of a vertical cylinder with a hemispherical dome roof and is supported by a reinforced concrete slab.
A continuous access gallery is provided beneath the foundation slab for inspection of the vertical tendons. Three concrete buttresses are provided for anchorage of the horizontal tendons.
Anchorages are designed such that tendons can be detensioned, inspected and retensioned readily during the life of the plant. The vertical cylinder wall is provided with a system of vertical and horizontal (hoop) tendons.
Vertical I
tendons are continuous to form inverted U's that extend over the dome.
The configuration of the tendons in the dome is based on a three-way system consisting
)
of two groups of vertical tendons oriented at 90 degrees with respect to each i
l other and a horizontal (hoop) group extending from the spring line to l
I approximately 45 degrees from the horizontal. Hoop tendons in both the wall and the dome are placed in a 240 degree system in which three tendons form two l
complete rings using three buttresses for anchoring the tendons. Each tendon is comprised of 170 - 1/4"O wires, terminating at each end with a cold formed i
buttonhead at the anchorage fixture.
The essential criterion for the operability of the sheathing filler material is to prevent corrosion of both the tendon wires and the anchorage components.
The material used in the Callaway Plant post-tensioning system, Visconorust 2090P-4, accomplishes this by a characteristic which gives the filler material an affinity to adhere to steel surfaces, its ability to emulsify any moisture in the system which nullifies its rusting tendency, and by its resistance to moisture, mild acids, and alkalis.
In addition, protection is afforded by each tendon wire being individually pre-coated with a grease, Amber 1601, prior to installation.
l Results from the first year tendon surveillance revealed voids in excess of 5%
for all tendons surveyed, without a loss of integrity to the system. From lab l
tests on the removed wires and grease, and from visual inspection of the tendon components, the filler material is performing its intended function of prohibiting corrosion of the tendon.
l l
The void in the tendon sheathing, as indicated by the refill volumes, which I
ranged from 6.2% to 12.4% of the net duct volume, may be attributed to a number of I
f actors :
1 1
1
r l
1
- 1) Visconorust: 2090P-4 has a coefficient of expansion which yields an i
expansion of about 1% per every 20 F.
Initial filling temperatures of the filler material averaged 160 F.
Cold weather conditions can cool'the filler material to 40 - F, giving a contraction of 6% of the net duct
]
volume. During the third year inservice surveillance of the tendons, the l
temperature of insitu filler material averaged 90 F, giving a contraction
'j of 3 to 4% from initial fill.
l l
- 2) Characteristics of the initial filling method may induce air entrapment into the filler material.
Pumping operations can introduce air into
'l filler material and may add up to as much as 2% of the net duct volume.
1 The tendons at Callaway Plant were initially greased between April and October,1981 by Inryco using current industry standard filling l
procedures.
- 3) During the initial filling operations, the tendon bundle was cold (ambient temperature of 65 F) and as the heated filler material (exit temperature of 140 F) was pumped into the sheathing void, it solidified on the surface of the tendon bundle, leaving small voids between the wires.
As the filler material gradually heated the tendon bundl'e, it is likely that the voids between the wires allowed migration of the filler material into the tendon bundle. Because this process is slow and gradual, it is l
reasonable to expect that it took place substantially after the filling
)
operation was complete and possibly during the surveillance refill 1
operation.
In addition, this type of migration could also occur at other l
l areas such as where tendons are in contact with the sheathing.
j
\\
\\
In addition, visual inspection of the exterior concrete of the containment
]
building af ter the initial greasing and during the surveillance revealed no signs I
of grease seepage from the tendon duct.
Therefore, refill volumes in excess of the lost grease during the surveillance indicate that the void existed within the j
l tendon duct boundary.
In summary, even under optimum filling conditions, voids I
ranging from 12-15% could be expected af ter the initial filling operation.
l I
The Callaway Plant tendons requiring net refill volumes of the filler material I
in excess of the 5% criteria have not shown any abnormal deterioration or l
degradation of strength. The lift-off forces for those tendons have been found to j
l fall within (or above) the predicted limits (see attachment 2, Preliminary Lift-l l
Off Force Data Sheets). Laboratory examination of the filler material has not l
been performed as of this date but the grease has shown no signs of discoloration l
or water present in the grease.
Visual inspection of the.different components of l
the anchorage system revealed proper coverage by the filler material with no signs l
of corrosion or presence of water.
l l
As indicated by the above, the function of the filler material in protecting l
the post-tensioning system is being maintained.
As long as sufficient filler l
material has been introduced into the system to completely coat the wires and I
anchorage system, corrosion protection is assured. Voids, such as those l
experienced at the Callaway Plant, can be expected due to the characteristics of I
the filler material and initial filling operations as noted above. Since each wire is individually pre-coated with Amber 1601, the degree of filling interstitial spaces, which comprise the net duct volume, is not directly related I
to the degree of coating which occurs, and therefore, is not a major indicator of the operability of the post-tensioning system. Based on the lift-off results, visual inspection and results from the first year surveillance, we have concluded that the structural integrity of the tendon and anchorage system has not been l
g adversely affected by the measured voids.
Since compliance with all remaining surveillance requirements for Tech. Spec.
4.6.1.6.1 was demonstrated, it is concluded that " voids in excess of 5% of the net
duct volume" have not resulted in any-degradation of the post-tensioning system,
' assuring the structural integrity of the containment structure.
In addition, future scheduled surveillance of the post-tensioning system and full pressure integrated leak rate tests will monitor the structural parameters of the containment to detect any potential abnormal degradation, assure continued operability of the system, and verify containment structural integrity on a continuing basis.
l As the lab tests for the 3rd year surveillance are still underway, this report l
has been filed to meet the 15 day action statement as specified in Tech. Spec.
l 3.6.1.6.B.
A supplemental report will be filed, should the laboratory tests on l
the tendon grease and wire reveal abnormal results.
