THE CONTINUOUS MONITORING OF BORIC ACID CONCENTRATION BY NEUTRON ABSORPTIOMETRY

Description: A neutron absorption cell was built to monttor continuously the boric actd concentration of reactor water flowing through a purtfication loop. The instrument was calibrated over the range from 0 to 2.65 g/l with a maxtmum absolute error of 0.05 g/-l. (auth)

Preparation of ultralow-friction surface films on vanadium diboride.

Description: In this paper, we present a simple annealing procedure (which we refer to as ''flash-annealing'' because of short duration) that results in the formation of an ultralow friction surface film on vanadium diboride (VB{sub 2}) surfaces. This annealing is done in a box furnace at 800 C for a period of 5 min. During annealing, the exposed surface of the VB{sub 2} undergoes oxidation and forms a layer of boron oxide (B{sub 2}O{sub 3}). In open air, the B{sub 2}O{sub 3} layer reacts spontaneously with… more

Chemical Technology Division, Unit Operations Section Monthly Progress Report, July 1960

Description: A critical review of the literature revealed no experiments on uranyl ion transfer from an aqueous to a tributyl phosphate phase which positively measured the kinetics of the chemical reaction at the interphase. Drawing isorhythmic lines on a three component diagram gives a complex correlation for the compaction of three sizes of glass beads. Neither the use of thoria sols nor high feed solution concentrations of thorium nitrate gave any significant increase in mean particle diameters over thos… more

Shaped Burnable Poison Development Program Under the Euratom Program. Quarterly Progress Report, July 1, 1963-September 30, 1963

Description: The number and size of Gd/sub 2/O/sub 3/ poison cylinders were computed for a large boiling water reactor with H/sub 2/O-toUO/sub 2/ ratio of 2.6, a U/ sup 235/ enrichment of 3.3 wt%, and Zr clad. The excess reactivity of the poisoned core was computed for the cold-clean, hot-clean non-voided, and hot full- power condition as a function of Mwd/t. For comparison, these calculations were repeated for B/sub 4/C as the burnable poison element for the same reactor. The use of Gd rather than B/sup 10… more

SPECTRAL SHIFT CONTROL REACTOR BASIC PHYSICS PROGRAM. Quarterly Technical Report No. 2, October-December 1960

Description: Basic physics parameters are being determined for lattices of slightly enriched fuel in moderators consisting of D/sub 2/O--H/sub 2/O mixtures of different concentrations. The principal effort was devoted to procurement and erection of equipment and materials needed for the critical experiments with D/ sub 2/O in the moderator, the exponential experiments, the hot exponential experiments, and the neutron age experiments. The erection of these facilities and the D/sub 2/O handling system was com… more

EXPERIMENTAL AND ANALYTICAL STUDIES OF REFLECTRO CONTROL FOR THE ADVANCED ENGINEERING TEST REACTOR. PART A. EXPERIMENTAL STUDIES WITH THE REFLECTOR CONTROL SYSTEM MODEL. PART B. ANALYTICAL STUDIES OF REFLECTOR CONTROL

Description: Studies of reflector control for the Advanced Engineering Test Reactor were made. The performance of various parts of the reflector control system model such as the safety reflector and the water jet educator, boric acid injection, and demineralizer systems is discussed. The experimental methods and results obtained are discussed. Four reflector control schemes were studied. The schemes were a single-region and three-region reflector schemes two separate reflectors, and two connected reflectors… more

PbO-free glasses for low temperature packaging

Description: Zinc polyphosphate glasses were examined as potential candidates for low temperature sealing applications. Glass-formation and properties were determined for the ZnO-P{sub 2}O{sub 5}, ZnO-B{sub 2}O{sub 3}-P{sub 2}O{sub 5} and ZnO-SnO-P{sub 2}O{sub 5} systems, and information about the short-range structures of these glasses was obtained by Raman and solid state nuclear magnetic resonance spectroscopies. In general, the most durable polyphosphate glasses have structures based on relatively short… more
