1-1/2-Loop Semiscale Isothermal Test Program: Program and System Description in Support of Experiment Data Reports.

Description: The isothermal test series is part of the Semiscale Blowdown and Emergency Core Cooling (ECC) Project conducted by Aerojet Nuclear Company for the U. S. Atomic Energy Commission. The test series consisted of ten blowdown tests and five hot-wall tests with emphasis on emergency core coolant delivery. The blowdown tests were conducted to investigate the effects of lower plenum geometry, heat transfer configuration, ECC injection location, downcomer gap size, and break size.

1 - FFTF-LMFBR seal test program, July-September 1974

Description: The objectives of the general seal test program are to: (1) conduct static and dynamic tests to demonstrate or determine the mechanical performance of full-size (cross-section) FFTF fuel transfer machine and reactor vessel head seals intended for use in a sodium vapor - inert gas environment, (2) demonstrate that these FFTF seals or new seal configurations provide acceptable fission product and cover gas retention capabilities at Clinch River Breeder Reactor Plant (CRBRP) operating environmenta… more

200-GeV ISA with room temperature magnets

Description: A conceptual design study of 200-GeV proton intersecting storage accclerators with room temperature magnets is presented. The key to this study was thc desire to keep the electric power consumptiom to an acceptable level (40 MW). The design has been optimized by choosing small-gap (4 cm) aluminum coil dipoles operating at about 15 kG. The luminosity of this machine is limited to about 10/sup 32/ cm-/sup -2/ sec/sup -1/ by transverse space-charg e effects. An order of magnitude higher luminositi… more

234-5 bank tank circulation studies

Description: In the Plutonium Reclamation Facility a critically-safe geometry of the processing vessels, combined with economical utilization of building space, has resulted in manifolded, vertical tanks for blending, receiving, holding, etc. The pumps attached to the bottom-outlet manifolds of the tanks are of a canned motor type. The extremely short life of these pumps (considerably below that expected even in severe abrasive and corrosive service) prompted a series of studies using glass tanks containing… more

Absolute length measurement at high pressure

Description: A length-measurement systcm is described that can make absolute length- change measurements of a meter-long specimen within a pressure vessel (to pressures of 8 kbar) with a fractional error of 3 x 10/sup -8/ even when changes in length of 4 cm occur. Possible uses of such a system for measuring the volume thermal expansivity (at pressure) and the isothermal bulk modulus (at pressure) are described. Moreover, it is noted that, when this system is combined with an ultrasonic velocity measurement… more

Action plan for promptly assessing Hanford`s nuclear material holdings

Description: The purpose of this discussion is to provide an action plan in the event of a threat in which nuclear material is declared to have been diverted or stolen. This procedure provides the framework by which the Atomic Energy Commission, Richland Operations Office (AEC-RL) will notify its contractors of a threat and direct required action and response to the AEC-RL. This procedure does not consider low-level radiological or biological threats, such as gram quantities. In general the materials to be … more

Additional Results Concerning Cross-Section Sensitivity of Tritium Breeding in a Fusion Reactor Blanket: ⁶Li, ⁷Li, and ⁹³Nb

Description: Previous work concerning cross-section sensitivity of the tritium breeding ratio showed ine effects of altering a partial cross section independently of other partial cross sections, permitting the total cross section to rise or fall. The results reported here are mostly for variations made while keeping the total cross section constant. The cases considered were for high and low values of the cross sections for ⁶Li(n,α)t, ⁷Li(n, n'α)t, and for ⁹³Nb(n, 2n) with compensatory changes in other cro… more
