Evaluation of LLTR series II test A-6 results. [LMFBR]
Series II test A-6 employed a DEG tube rupture located 222.9 inches above the bottom of the LLTI shroud at the periphery of the tube bundle. The test yielded a peak pressure at the leak site of 340 psia and peak measured temperatures of 2150/sup 0/F. The initial acoustic pressure spike measured upstream of the RD-1 rupture disc assembly of 295 psia was insufficient to burst the upstream rupture membrane. (The LLTV was supposed to be completely filled with sodium. However, review of test data has indicated that approx. 8 ft/sup 3/ of gas was present in the upper region of the LLTV at the time of test. The presence of this gas in the test article contributed to the reduction in the magnitude of the acoustic pressure spike.) The acoustic pressure spikes diminished and a gradual system pressure rise controlled by the compression of the cover gas in the surge tank occurred. When the system pressure increased to 340 psia about 6.5 seconds after leak initiation, the upstream rupture disc burst followed by burst of the downstream disc about 54 milliseconds later.
