Abstract

Series II Test A-2 employed a double-ended (DEG) tube rupture 122'' above the lower end of the LLTI shroud under typical evaporator startup conditions. The leak site was located 2'' below Spacer No. 4 at the same location as Test A-lb which employed nitrogen as the inert non-reactive injection fluid. The test yielded peak pressures of 375 psig in the leak site region and 485 psig at the upper tubesheet approximately 10 ms and 12 ms, respectively, after tube rupture. Higher peak temperatures (approx. 2200/sup 0/F) were measured in this test than during Series I sodium-water reaction testing (peak temperatures measured during Series were about 1900/sup 0/F maximum). These high peak temperatures occurred in Test A-2 long after the tube rupture (approx. 8 seconds) and did not contribute to the acoustic peak pressures produced in the first few milliseconds.

Evaluation of LLTR series II test A-6 results. [LMFBR]

Technical Report Amos, J.; Knittle, D.; Chen, K.; ...

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 regionmore »« less

Evaluation of LLTR Series II tests A-1A and A-1B test results. [Large Leak Test Rig]

Technical Report Shoopak, B; Amos, J; Norvell, T

The standard methodology, with minor modifications provides conservative yet realistic predictions of leaksite and other sodium system pressures in the LLTR Series II vessel and piping. The good agreement between predicted and measured pressures indicates that the TRANSWRAP/RELAP modeling developed from the Series I tests is applicable to larger scale units prototypical of the Clinch River steam generator design. Calculated sodium system pressures are sensitive to several modeling parameters including rupture disc modeling, acoustic velocity in the test vessel, and flow rate from the rupture tube. The acoustic velocity which produced best agreement with leaksite pressures was calculated based onmore »« less

Summary of results from velocity profile tests and wastage tests in support of LLTR series II test A-4. [Large Leak Test Rig]

Technical Report Greene, D.

The following conclusions were drawn from the experimental program conducted in support of LLTR (Large Leak Test Rig) Series II Test A-4: Fabrication technique for making precise slits was developed. Wastage boundary agrees with velocity profile boundary. Circumferential slit angles would have to be 120/sup 0/ to ensure adequate coverage of adjacent tubes. 120/sup 0/ circumferential slit weakens tubes such that maintaining desired slit dimensions for LLTI application is not considered practical. Use of intermittent slit geometry would be required. 120/sup 0/ slits, precisely machined and precisely aligned with target tubes, produced different penetration rates on adjacent tubes.

Status of prototype rupture disc testing in the large leak test rig

Technical Report Amos, J

The prototype CRBRP double membrane rupture disc assembly is being performance tested in conjunction with the LLTR Series II Large Leak Program. In May 1979, the double membrane disc assembly was inadvertently activated during sodium system pressure instrument calibration. This experience indicated that the rupture disc burst at essentially the design burst pressure when a gradually increasing state pressure was applied. The area of membrane opening was found to be about 25 to 30% of the cross-sectional area. In July 1979, the disc assembly was again tested (this time in a single membrane configuration) in conjunction with the first LLTRmore »« less

This document contains a complete set of valid and final digital and analog data plots for LLTR Series II, Test A-2. Included is an Accuracy Statement regarding this data as required by Revision 0 of the GE Test Request, Specification No. 23A2062. The Series II, Sodium-Water Reaction Test A-2 was performed in the Large Leak Test Rig (LLTR) at the Energy Technology Engineering Center (ETEC). This was the third of three planned double-edged guillotine (DEG) rupture tests of a single tube which will be followed by a number of small leak tests.
