ANP PROJECT PROGRESS REPORT resumed. A new, 4-in.-dia cold trap was installed in this loop. This cold trap is identical to the previously used cold traps except that the copper cooling coil has been replaced by a stainless steel coil and additional thermocouple wells have been provided to determine the temperature profile inthe cold trap. Operation thus far has been devoted to cold-trap evaluation under simulated ART operating conditions. Operation of small heat exchanger test stand C was terminated after 634 hr when ORNL heat exchanger No. 2, type SHE-2, developed a high resistance to fuel flow during power operation. This heat exchanger was replaced by Struthers-We1 Is Corp. heat exchanger No. 1, type SHE-2, and test operations were resumed. When heat transfer conditions were initially established, this heat exchanger also began to develop a high resistance to fuel flow, similar to that experienced by ORNL heat exchanger No. 2. At this time, a leak developed in the resistance heater and the stand was 60 Fig. 1.4.8. York Radiator No. 7 (Revised Design). UNCLASSIFIED PHOTO u875 w shut down. The resistance heated section was removed for mete I lur gica I examina t ion. Examination of ORNL heat exchanger No. 2 disclosed extensive buildup of metal particles throughout the fuel side of the heat exchanger that s would account for the marked increase in resistance to fuel flow. It is felt that examination of Struthers-Wells heat exchanger No. 1 will reveal the same condition but to a lesser degree. Evidence of mass transfer and self-welding in certain areas of the resistance heater indicated that extreme hot . spots had occurred in the heater. This would account for the buildup of metal particles in the heat exchanger. A section of the resistance heater at which severe overheating occurred is shown in Fig. 1.4.9. The metal particles which built up on Y one of the heat exchanger tubes are shown in Fig. 1.4.10. A new heater design has been completed, and a -. heater is being fabricated. The test stand is currently being operated as a NaK loop to obtain a-

Upon receipt of a new 25-tuk small heat exchanger (type SHE-7),14 the Struthers-Wells heater exchanger No, 1 will be replaced, and the test stand will be put back into ful I operation.

J. Milich, ANP Quar. Prog. Rep. Sept. 10, 195% ORNL-1947, p 54. has been found that care must be exercised duing initial cold-trap operation to prevent oxide plugging during main system heatup. The original design specified copper cooling coils which necessitated maintaining the cold-trap temperatures below 700°F at all times to prevent excessive oxidation of the copper. This meant that at system temperatures above NOOF, with high contaminant saturation levels (800 to llOO°F), it was possible to pre- cipitate material in the economizer which tended to settle out and plug the cold-trap inlet line. One cold trap with a stainless steel cooling coil has been tested. This trap was brought up to 1200°F with the main system. The temperature of the trap was then gradually reduced by supplying maximum air cooling and reducing the cold-trap NaK flow. By using this method of startup, no indication of serious plugging was observed: No 61
