TEST PURPOSE The purpose of this test was to show that the bearing plates, which will be used in the base slab of the Russellville Reactor Unit #1, perform adequately. The test was conducted as a tendon tensile test.
The bearing plate performance is judged by deflection criteria. Tendon and anchor plate performance is included in this test, but as the only concern is to the bearing plate, these results are not discussed in this report.

ACCEPTANCE CRITERIA:
Successful completion of the following requirement will be con-sidered as proof of the adequacy,of the bearing plate.
The bearing plate should have elastic behavior after the initial set has occurred.

TEST FACILITY: vive (5) million pound testing stand (see Fig.1).
- TEST ARRANGEMENT: The test arrangement consists of the following components:
- 1. Concrete tes t blocks 48" x 48", total length 19 feet.
- 2. Anchoring block 54" x 54" x 48".
- 3. Ram base plate.
4 Stressing unit, with two (2) 625 ton rams, pull rod and stressing nut.
- 5. Pumping unit.
- 6. 186-wire (1/4" 0) test tendon with non-stressing end anchor
, on the. anchoring block and an internally threaded anchor head on the other end. (Min. Guaranteed Ultimate Strength = 2,192 K).
- 7. Dial indicators on anchor plate and bearing plate (see Fig. 7).
EQUIPMENT:
- 1. Ram: 2 two-way acting hydraulic rams.
Capacity - approximately 1250 tons at 10,000 psi hydraulic pressure.
Effective ram area -
120.0 + 129. 3 = 249.3 sq. in.
Travel - 12 inches.
- 2. Pump: High pressure hydraulic pump, maximum pressure 10,000 psi.
Dial range - 10,000 psi.
Accuracy of pressure readings - + 25 psi.

Accuracy of deformation readings - 1 0.00025".
- 4. Spale Barl Attached to the ram to measure the elongation.
Accuracy of elongation readings - f 0.005".
TENDON INSTALLATION:
The anchoring block is reinforced according to Fig. 6. The trumpet-bearing plate assembly is bolted to the formwork. The tendon is completely shop fabricated with anchors on both ends. The anchor head is pulled through the test blocks and coupled to the pull rod. The test anchor plate is bolted to the bearing plate.
The tendon and its hardware are fabricated according to Figs. 2, 3, 4, and 5.
They undergo our standard quality control.
~
TEST PROCEDURE :
Concrete cylinders were taken at N time of placing. Strength and Modulus Tests on cylinders were done by TETCO Testing Laboratories accord-ing to the enclosed report, The results are plotted in strength-time and modulus-time curves respectively.
Preceeding the test set-up, the bearing plate and the anchor plate were provided with a 2" grid on their outer surface. These two surfaces were profiled with a dial indicator on a specially designed " profiling frame",
which provides a true three-point-bearing for any profiling sample. This method provides a higher accuracy in profiling the large bearing plates.
Dial indicctors, located as shown on Fig. 7, were mounted on the bearing and anchor plate. They were set to zero prior to and after the first i

.s loading cycle. They were removed after completion of the third loading cycle.
The Loading Sequence was as follows:
First Loadino Cycle:
The tendon was stressed in stages to a pressure reading of 5,000 psi, released to 500 psi, and loaded again to 5,000 psi. A 1,500,000 lb. load cell was used to give some indication of the relationship between pressure reading and actual force.
Second Loadino Cycle:
The tendon was stressed in stages to the overstressing force of 77% of the guaranteed ultimate strength and released again. This loading was repeated twice, f '
- i. Third Loadino Cycle:
The tendon was loaded gradually up to 96% of its guaranteed ul-
- timate strength and then unloaded again. This loading was repeated three (3) times.
Fourth Loadino Cycle:
The tendon was stressed to failure. The test was concluded after nine (9) wire breaks. It was apparant that elongation was obtained without increasing the load.
The load stages were set at pressuro readings mentioned on pages 38 - 40.
For each stage, pressure, elongation, and the deflections were read care-o fully. .
After the test, the bearing and anchor plate were removed from the J'
test specimen and profiled in the same way as done prior to testing.

(, NOTE: As the tables show the deformations relative to an arbitrary level, which is not necessarily identical with the zero-level in the anchoring block, the profiles give a picture of the difference in deformation for any two points of the plate but not the true absolute deformations. However, for the anchor plate, the profiling level was adjusted to the test zero level according to the initial set readings on the dial indicators. The bearing plate profiles are recorded "as read".
