PUREX PULSE COLUMN STUDIES-1960

Description: A series of pilot plant runs was conducted to define new cartridges for increasing the capacity in the Purex 1 Bx, 2A, lC and 2E columns and eliminate plastic cartridge failures in the HA column scrub section, the HS column and the 2A column. The most favorable designs are presented and data from the various runs are included. (J.R.D.)

Exact Semiclassical Calculations of Translational-Vibrational Energy Transfer

Description: We present "exact" calculations, by the semiclassical method, of vibrational excitation of a harmonic diatomic molecule A-B, in its ground vibrational state, upon collinear collision with an atom C. Results are compared with those of first-order quantum mechanical time dependent perturbation methods and those of purely classical methods.

Evaluation of Wire Scanner for SM-1

Description: Preliminary design concepts are presented for a wire scanner for experimentally evaluating spatial variations of neutron flux in the SM-l reactor core. Results of a literature search and determination of optimum criteria for flux mapping the core in minimum time dictated requirements for design concepts and specifications. The utility of both manually instrumented and automatically instrumented wire scanners was analyzed with respect to rapidity of measurement, selectivity of detector location,… more

NUCLEAR AEROSPACE SAFETY PROBLEMS

Description: Safety problems that have arisen in the conquest of space and are of a nuclear origin are discussed. Space radiation such as cosmic radiation, geomagnetically trapped corpuscular radiation, and solar flare radiation and radiations inherent in nuclear auxilliary power systems are considered. Problems created by the use of nuclear propulsion systems are emphasized. Launch pad problems and core disposal are discussed (M.C.G.)

Production Test IP-300-A: Irradiation of twenty inch natural uranium tube and tube elements with hot headed inner tubes

Description: The objectives of this production test detailed in this report is to evaluate the behavior during irradiation of tubular fuel elements with hot-headed end closures. With natural uranium twenty-inch tube- and-tube elements will be irradiated to a goal of 2500 MWD/T in the KER loops. The inner tubes will be closed by the hot-heading technique and the outer tubes will have normal welded closures.

Specifications for Multifunction Storage Unit Type I

Description: The Multifunction Storage Unit, Type I is a storage device capable of storing geometrical information in visual display form. The storage is accomplished by means of an electrostatic storage cathode ray tube. The Storage Unit consists of this storage tube and its associated circuitry. Associated circuitry is considered to be all circuitry required by the storage tube itself which is necessary to make the unit a self-contained storage unit. The following six external signals are all that is requ… more

Radioactivation Analysis

Description: The development of nuclear reactors and other sources of nuclear particles has provided the analyst with a new method which has been successfully applied to the determination of microgram and even submicrogram quantities of many elements. In this method, known as "radioactivation analysis," the element to be determined is "activated" through some type of nuclear reaction which produces a radioactive isotope of the element. Since the radioisotope produced decays with its own characteristic radia… more

Research and development allocations and plant assistance support, FY-1966

Description: This report discusses an allocation of $1,320,000 of 02 Reactor and Metallurgy funds which was previously made to the Pacific Northwest Laboratories. The Process Technology work order support which N-Reactor Department expected to provide during FY 1966 was estimated. The R&D allocation was based on the 189 budget proposals which were prepared early in 1965 and program identifications were provided. The integrated five year research and development program was subsequently formulated with the a… more

Stress-Dependent Interactions Between Cesium and Other Materials. Summary Report, February 15, 1962-February 15, 1963

Description: Metals and alloys germane to thermionic energy converter usage were screened for embrittlement by liquid cesium. Techniques are described for more detailed studies of ceramics and susceptible metals. Definite reductions in tensile ductility were observed for 302 stainless steel and molybdenum. Bend ductility was lowered in titanium, titanium-8 aluminum-4 vanadium alloy, niobium, tantalum, and silver-- copper eutectic solder. Some difficulty in reproducibly wetting samples was evident. Slightly … more
