Extrusion of I and E `O` size tubing to evaluate reduction in extruded O.D. and the use of pressed salt follower blocks: Experiment Number U-21

Description: The object of this experiment was to extrude normal uranium hollow billets to I and E `O` size tubing with reduced extruded O.D. and also to evaluate the use of pressed salt follower blocks. Pressed salt (NaCl) follower blocks under various conditions of pre-heat temperature were compared with the standard graphite at 800 F. Even though some yield reduction results, it was concluded that pressed salt follower blocks at 300 F represent a substantial cost reduction due to the extreme price differ… more

FLOW DISTRIBUTION ACROSS THE CORE. CORE I, SEED 2. Section 1. Test Results T-550097

Description: An investigntion was conducted to determine flow distribution characteristics within the core and determine any relative shift in flow between the seed and the four blanket regions. The highest average flow measured throngh the blanket regions, for each loop arrangement, was established, however the flow in other regions was not consistent enough to establish a pattern. (J.R.D.)

Flow Distribution Across the Core. Core I, Seed 2, Section 2. Test Results T-550097

Description: An investigntion was conducted to determine the reactor coolant mixing charactsristics of the inlet plenum chamber. It was found that mixing in the inlet plenum was slight, and flow from a given loop is corfined mainly to its quadrant of the core. There appears to be no significant change in the flow rate through the fuel assemblies monitored with the reactor coolant introduced at various temperatures and the reactor coolant pump on either fast or slow speed.

Sensitivity testing of liquid high explosives

Description: This article describes a test procedure for a liquid high explosive. The liquid to be tested is NTN, a mixture of nitromethane, tetranitomethane, and 1-nitropropane in 52, 33.3, and 14.7 weight per cent. The test is to study the sensitivity of the explosive to shock by firing it in projectiles from a M1A1 155mm howlitzer, with a charge such that it will not exceed 16,500 g`s acceleration.

THE DYNAMIC PINCH AS A HIGH-INTENSITY LIGHT SOURCE FOR OPTICAL MASER PUMPING

Description: >The optical radiation that occurs in a dynamic plasma pinch experiment depends in part on the amount and type of impurity atoms present in the system. By proper choice of these impurities, it should be possible to tailor the optical radiation from the pinch in intensity, spectrum, and duration such that the kinetic energy of motion (1OO to 1OOO joules) appears as radiation enengy in less than 10/sup -6/ sec. This should provide a good method of optical pumping for pulse optical maser operation… more

High-Temperatuer Creep Evaluation in Carbon Dioxide Atmosphere : Summary Report, October 1, 1959 to March 31, 1961

Description: This report follows an investigation made to determine creep-rupture data for three sheet materials. Fourteen of sixteen tests were made in an atmosphere of carbon dioxide within hermetically sealed capsules, analyzing the reaction of the three sheet metals: 347 stainless steel, iron-aluminum-chromium alloy designated 261C, and a zirconium-base alloy, AE1H. Minimum creep rate, per cent elongation, and rupture life were determined and reported.

Defect-tests of power generating co-extruded fuel rods

Description: The effect of the many parameters which may influence the failure behavior of coextruded fuel material are being evaluated by Reactor & Fuels Research & Development Operation. This knowledge will be helpful in the design, fabrication, and operation of fuel elements so that the hazards and time involved at failure may be minimized. Many of the various tests performed on unirradiated coextruded fuel material have been in isothermal systems. The tests reported here were performed on power generati… more

EFFECT OF TEMPERATURE ON RADIATION-INDUCED CONTRACTION OF REACTOR GRAPHITE

Description: The distortion behavior of graphite as a function of irradiation temperature is reviewed. The behavior of needlecoke and CSF graphite was examined over moderate exposures in the GETR. Results showed needle-coke to be less contracting than CSF. Details of contraction show a minimum contraction rate per 10/sup 21/ nvt at 600 to 800 deg C for both types. Limitations to be placed on the data presented are listed. (P. C.H.)
