Air Diffusion in the Air Operating Water Flask. Section I. Test Results DL-S-205 (T-641110)

Description: The purpose of the test was to determine the effect of continuous air pressurization of the Valve Operating System water flask on the the oxygen concentration of the water in the flask. Oxygen concentration in the Valve Operating System water flask increased during the testing period of seventeen days. It cannot be determined from the data obtained if equilibrium oxygen concentration was reached. The distribution of oxygen in the flask at the end of 17 days varied from approximately 12 ppm in t… more

Fuel Handling, Service and Waste Disposal Buildings Drain Test. Section I. Test Results DL-S-230 (T-641115)

Description: The purpose of the test was to prove the integrity of the non-active drains, the special drains, the sanitary drains, the chemical waster drains and the storm water drains by means of a water flow test and visual inspection. The two roof boxes and the one floor drain of 1B Auxiliary Equipment Room did not drain properly. The lab sink in the west end of the Radiochemistry Lab drained to the Special Monitored West Transfer Tank instead of the Monitored Waster Transfer Tank. All other drains funct… more

Nuclear-Conventional Power Plant Cost Study. Conventional Coal Fired Power Plants : 25,000 KW to 325,000 KW for Argonne National Laboratory, Lemont, Illinois

Description: In order to establish a basis for comparing the estimated cost of nuclear power plant designs, a set of general and detailed design considerations for conventional coal-fired power plants was established. Five preliminary designs of conventional coal-fired power plants ranging in size from 25to 325 mw were selected, and cost estimates were prepared. ( A.C.)

Fast Neutron Scattering from Thick, Plane Slabs of Concrete, Aluminum, and Water

Description: The purpose of the experiment was to obtain scattering data for fast neutrons. Evidence is south as to the validity of the albedo approach in predicting the back-scattered neutrons does from large, thick plane media. If a neutron energy flux corresponding to a dose rate of J+ passes from one medium containing a source into a moderating medium a quantity of energy will pass back into the medium containing the source. The quantity measured was the dose rate.

Iodine Monitoring at the National Reactor Testing Station

Description: Operations at the National Reactor Testing Station generally involve new types of fuel elements or reactors or the chemical processing of spent fuel elements. Because the isotopes of iodine are produced in high yield during fission and their short half lives permit equilibrium concentrations to be built up rapidly considerable inventories of these isotopes will be present after a reactor has operated for a relatively short length of time. The gaseous nature of the element allows its escape afte… more

Periodic Radiation Survey. Section III. Second Performance. Test Results DL-S-184, T-612076

Description: The purpose of the test was to determine the rate of radioactive decay of the hairpin loops after isolation and to determine the changes in radiation level resulting from continued operation of the reactor at power. The results indicate that the radiation decayed very rapidly after isolation of the hairpin loop. After one minute, the level had decayed to nearly its lowest point. Discrepancies which appear in the data can be attributed to two factors: (1) changing the survey meter part way thro… more

Reactor Plant Container Air Cooling System. Section III. Second Performance. Test Results DL-S-136 (T-550090)

Description: The purpose of this test was to determine the performance of the Reactor Plant Container Air Cooling System with four reactor coolant loops at operating temperature. Due to the fact that the test was performed with the chamber door open, no significant conclusion can be arrived at concerning the efficiency of the Air Cool System. The 1B supply fan circulated approximately 20 per cent less air than the 1A fan during the test. Later investigation revealed that the turning vanes above the 1B dampe… more
