ANP PROJECT PROGRESS REPORT Auxiliary NaK Pump Development Tests H. C. Young J. G. Teague M. E. Lackey Water tests were conducted on the auxiliary NaK pump (model PK-A). The volute used for these tests consisted of two brass volute halves bolted together. The volute flow passage was accurately milled in each volute half. The test impeller was fabricated of brass, with vanes silver-soldered to the hub and soft-soldered to the inlet shroud. The pump assembly was tested in the test loop used for the water tests of the primary NaK pump.9 A 60-hp d-c drive motor was used. No changes were necessary in the instrumentation, except that a new orifice was installed to measure the lower flow rates. Performance and cavitation data were obtained for as wide a flow range as possible within the practical limits of volute hydraulic unbalance, and the final head vs flow curves are presented in Fig. 1.4.5. A plot of pump shaft horsepower versus flow for some head and flow conditions is shown in Fig. 1.486. The volute hydraulic unbalanceoverthe design range was found to be quite satisfactory, - 450 400 350 300 E 250 0 a y 200 450 400 50 a - ORNL-LR-OW644957 0 400 200 300 400 500 600 700 000 FLOW (gpml Fig. 1.4.5. ART Auxiliary NaK Pump (Model PK-A) Performance Curves of Head vs Flow Show- ing Efficiency and Volute Pressure Balance Lines. 54 and therefore this pump will be satisfactory for use as the special NaK pump for cooling the ART fuel fill-and-drain tank. This pump requires 300-gpm flow at a 275-ft head. The impeller diameter, the dynamic seal vanes, and the top labyrinth seal are the same as those for the primary NaK pump, and the speed ranges of both pumps are the same. Therefore the radial and axial clearances determined by the primary pump tests were used for the auxiliary pump. The pump showed satisfactory degassing characteristics with these clearances. After the initial performance tests were com- pleted, a 0.023-in. spacer was installed between the volute halves, and tests were conducted to determine whether the addition of the spacer would change the volute hydraulic unbalance. The pur- pose of these tests was to ascertain the allowable tolerances for use in welding the Inconel volute halves together. The volute hydraulic unbalance was measured during these tests by eight static pressure taps equally spaced in the volute near the periphery of the impeller. The static pressure readings at any of the eight taps, for a given discharge head and a set flow rate, did not change over 1 psi from the measurements taken without the spacer. In general, the water tests indicate that the pump will meet the head and flow conditions required for use in the ART, both for the auxiliary and the special NaK pumps, The design conditions are in the range of minimum volute hydraulic unbalance. Cavitation characteristics of the pump, based on extrapolations from water to NaK, indicate that a pump tank gas pressure of 14.4 psia, or -0.3 psig, should be sufficient to suppress cavitation at design flow for a NaK temperature of 1282OF, as compared with a required pressure of 6 psig for the primary NaK pump at the same NaK temperature. Primary and Auxiliary NaK Pump lest Stands H. C. Young J. G. Teague Fabrication of all parts for two primary and two auxiliary NaK pump high-temperature test loops is under way. At present, the pump volutes are the most critical delivery item. A method of profile- machining the volute halves from a pattern is being used. Several primary pump volute halves have been received, and the vendor is now setting up for profile-machining of the first auxiliary pump volute halves. A series of welding tests were conducted to determine the joint preparation and the welding w c - -. * . . c-,
