The Decay of Neptunium-238 (open access)

The Decay of Neptunium-238

>A study was made of the energy levels of Pu/sup 238/ which are populated by Np/sup 238/ beta decay, by an examination of the Np/sup 238/ conversion electron spectrum in high-resolution beta spectrographs. The general features of the level scheme as previously given were unchanged but several new transitions were observed, with energies of 119.8, 871, 943, 989, and 1034 kev. Two new levels are postulated at 915 and 1034 kev which accommodate all but the 943-kev transition. A possible assignment of the 943-kev transition to the (0+.0) state of the beta vibrational band is discussed. In addition, the weak 885-kev transition from the 2+ state of the gamma -vibrational band to the 4+ state of the ground band was seen and its relative intensity determined. Comparisons were made of the experimental relative transition intensities of the three photons depopulating this band with those predicted from the rules of Alaga et al.; only fair agreement was noted. A discussion is given of the beta decay branchings and log ft values of Np/sup 238/ decay in terms of the postulated characters of the Pu/sup 238/ states and the measured spin of Np/sup 238/. (auth)

Design and Mass Transfer Study for New Multistage Fluidization Reactor (Thesise (open access)

Design and Mass Transfer Study for New Multistage Fluidization Reactor (Thesise

A preliminary design enabling the downward transport of solids in multistage fluidization reactors is discussed, and a program to improve the preliminary plate design is reported. A three-stage 6-in. dia. column was constructed to obtain and correlate design and mass-transfer data. The preliminary plate design was improved by incorporation of a cover screen as a part of each plate which sandwiched the large nonfluidized beads, resulting in improved stability, and the use of internal vibration which permitted control of the fluidized solids bed depth on an individual stage basis. All of the design data were correlated into a set of five equations. From the equations it is possible to calculate the amount and size of nonfluidized beads that are necessary to achieve a given throughput rate of any material under any operating conditions. The experimental work is reported in the areas of development of a design correlation using a glass bead-air system, and investigation of coluum efficiency from mass-transfer runs involving the adsorption of water vapor from air by silica gel.

Grounding of Beta Sources by an Auxiliary Alpha Source (open access)

Grounding of Beta Sources by an Auxiliary Alpha Source

A Po/sup 210/ source was used to furnish a reliab1e ground for both electron and positron sources. This was done to prevent the electron and positron sources from charging during BETA spectral studies in magnetic lens spectrometers. An approximately 20- mu c Po/sup 210/ source was placed 1.2 in. behind a 4- mu c Na/sup 2 / 2>s positron emitter backed by 20- mu g/cm/sup 2/ Formvar in the spectrometer; this arrangement resulted in a charging rate decrease of approximately 80%. When the source was placed 0.5 in. away, no charging was detectable over a period of more than one week. The discharge is attributed mainly to the loss of electrons from the source and backing caused by ionization of alpha particles since few alpha particles are stopped near the source. (B.O.G.)

HEAVY-WATER-MODERATED POWER REACTORS ENGINEERING AND ECONOMIC EVALUATIONS. VOLUME II. ENGINEERING STUDIES AND TECHNICAL DATA

The results of preliminary design and evaluation studies of various concepts of a power reactor that is moderated by heavy water and fueled with natural uranium are presented. Twenty-nine conceptal designs were developed for reactors ranging in capacity from 100 Mwe to 460 Mwe. Resigns were prepared for hot- and cold-moderator reac tors of the pressure vessel type, with liquid D/sub 2/O, boiling D/sub 2/O, E/sub 2/O steam, and helium as coolants. Also studied were cold-moderator pressure tube reactors cooled with liquid D/sub 2/O and boiling D/sub 2/O. The repont includes the results of engineering studies of the reactor systems, electrical generation facilities, and auxiliary equipment. (auth)
