- 1. CL INTF0 DUCTION The surveillance program for the Oconee Nuclear Station, Unit 2 , reactor building post-tensioning system was defined, and.is executed, in order to' assure the continued quality of the system. 1te program consists of periodic inspections of nine pre-selected tendons - three horizontal tendons, three vertical tendons and three dome tendons - for symptoms of material deterioration or force reduction. The program assesses the condition and functional capability of the system and, therefoce ,
verifies the adequacy of the system and provides an opportunity to take proper corrective action should adverse conditions be detected .
The requirements for the program are detailed in the Oconee Technical Specifications, Sections 4.4.2.1 and 4.4.2.2.
December 13 through December 20.
Surveillance was conducted 1974 in accordance with approved test procedure PT/0/A/150/14, Reactor Building Tendon Surveillance Program, and the results of this initial inspection are reported herein .

2.2 CONCLUSION
S Based on the tests and inspections described her i the post-tensioning system for Oconee Nuclear Ste n, it is concluded that excellent condition, ation, Unit 2, is'in that the functional capability of the~syst em has not diminished, and that the system shows no detectable e id j.
occurrence of any adverse deterioration. v ence of the 9
3.0 RESULTS 3.1 SHEATHING FILLER The sheathing filler at the ends of the nine surveillance tendons was visually examined. The filler coating on the end anchorage components, and the color and consistency of the filler, were found to be acceptable, with no evidence of water being present - see Table 1.
Samples of sheathing filler were obtained from each of three tendons from which a wire was removed. This filler was visually examined and no signs of water nor any discoloration of the sheathing filler was evident.
Laboratory analysis of the filler samples found impurities to be within acceptable limits - see Table 2.
3.2 END ANCHORAGE COMPONENTS The results of the end anchorage component inspections are given in Table
- 3. Buttonheads were inspected for acceptable shape, general appearance, l
cracks and corrosion. No buttonhead defects or missing buttonheads were observed. Stress washers,. shims and bearing plates were visually inspected for cracking and corrosion. (Some millscale and minor surface corrosion were present on the edges and faces of shims and bearing plates. However, this condition existed at the time of installation ar.d no deterioration has occurred in the interval since installation).
3.3 LIFT-OFF FORCES Lift-off forces were obtained for each surveillance tendon - see Table 4.
From these readings an average force per wire was determined. The long-term trend of these wire forces is shown graphically in Figure 1. Lift-off forces were within the range of predicted values, considering the effects i
of concrete creep and shrinkage, steel relaxation and initial structural deformation.
', i l
3.4 WiltE SURVEILLANCE AND TESTING One survefilance tendon of each directional group was relaxed -'lD28 ,
13H9 and 23V14.
One wire was removed from tendons 1D28, 23V14, and 13H9.
The wires. removed were visually checked for corrosion and pitting'-
and to determine their general condition.
The tendon wires-were found to contain minor surface scratches, resulting from insertion of the tendons into their sheaths at the time of installation, and heat treating _ i discoloration.
The general condition of the wires was determined to be equivalent to their condition at time of initial installation.
Three specimens were cut from each of the extracted wires for tensile testing.
The samples were taken from the ends and the middle of each of the wires.
The ultimate strength of each of the specimens was determined by tensile testing by the Prescon Corporation, Simpsonville, South Carolina.
These tests are summarized in Table 5 and revealed no signifi-cant changes in the ultimate strength of the wire as compared to results obtained during initial acceptance tests.
3.5 RETENSIONING AND FILLER REPLACEMENT Following wire removal the tendons were retensioned to approximately the same stress level indicated by the lift-off force data obtained during this surveillance.
The sheathing filler which was removed during the surveillance process was replaced with new filler.
