Because of the large gamma heat generation in the core of the Engineering Test Reactor, the thermal stresses in the KAPL ETR F-10 and the BAPD- KAPL 6 x 6 in-pile tubes result in fatigue and possible growth in the diameter of the tube. To prove the operability of these in-pile tubes, a scaled-down section of in-pile tube was installed in the KAPL HF-2 loop, a high-temperature, high- pressure, heat transfer facility. The tubular test section was alternately heated and cooled for a total of 10,020 thermal cycles and 8 pressure cycles. The maximum tangential stresses were 16,570 psi due to pressure and 98,680 psi due to intetnal heat generation The test section was inspected several times during the test, and ro evidence of growth or cracking was observed.
