THE ASSEMBLY, SODIUM BONDING AND INSPECTION OF EBR-II BLANKET RODS

Description: The Experimental Power Breeder Reactor (EBR-II) is a heterogeneous, unmoderated, Na-cooled reactor developed to provide engineering and operational information on fullscale central-station power plants. The enriched U-fissium alloy fuel is blanketed with depleted unalloyed U in type 304 stainless steel tubes. Details of fabrication and loading of these rods are given. (J.R.D.)

Chemical Problems in Advanced Gas-Cooled Reactors

Description: The chemical problems largely involve gas- and solidphase chemistry where chemical reactions and physicochemical processes occur at elevated temperatures ( approximately 4000 deg F). The high temperatures require that the fuel bodies and moderator be made of refractory materials and may preclude the use of metal cladding. Areas of concern include reactor materials and primary coolant systems, where most of the problems involve mass transfer. Reactions are discussed which can lead to carbon tran… more

A Comparison of Radiation--Induced Graft Copolymerization Utilizing Electron Accelerators and Isotope Sources as Radiation Initiators

Description: "The grafting of methacrylic acid, styrene (2: 1 mole ratio) co-monomer mixture on polypropylene film and fabric, was studied to compare electron accelerators and isotopes as sources of radiation. An aluminum block that contalns i/8-in.-deep pockets covered with Mylar film for holding sample and monomer during mutual irradiatlon was developed. A preliminary comparison was made in post grafting polypropylene film and fabric preirradiated with Cow and with an electron accelerator source. It was f… more

The Decay of Neptunium-238

Description: >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… more

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

Description: 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 w… more

Grounding of Beta Sources by an Auxiliary Alpha Source

Description: 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… more

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

Description: 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 r… more

THE HELIUM PURIFICATION SYSTEM FOR THE PROPOSED 800 MWT PEBBLE BED REACTOR

Description: A helium coolant purification system was designed for the proposed 800 Mwt Pebble Bed Reactor. The purification system will operate on a coolant side steam with a flow rate 1% of the total coolant flow, and there are provisions for radioactive and nonradioactive contamination removal. Primary equipment components are dual oxidizers, an economizer heat exchanger, a gas cooler, dual absorbers, a fission-product gas-delay trap, and dual filters. The fission- product trap is sized to provide a hold… more

Instability Studies With EBR-I, Mark III

Description: The results of instability studies suggest that the operational characteristics of the fully ribbed and rigid Mark III loading are governed by feedback processes that guarantee safe and stable operation under normal operating condiiions. No evidence of positive reactivity effects was noted for the fully-ribbed rigid core. Logical extrapolations of full-power full-flow test data indicate that the reactor could be brought into a resonant condition for power levels exceeding 1000 Mw. Strong nonlin… more

KINETIC EXPERIMENTS ON WATER BOILERS-"A" CORE REPORT. PART III-PILE OSCILLATOR RESULTS

Description: A brief review of the theoretical water-boiler reactor-power transfer function is presented as background for the experimental determination of the ratio of effective prompt neutron lifetime to the effective fraction of delayed neutrons, 1/beta. The preparation and performance ot the experiment are discussed with special emphasis on equipment procedures, and measurement errors. The results, which strongly support a seven-delay-group model of the reactor, are presented and compared with theoreti… more

A LUNAR POWER PLANT

Description: A concept of a nuclear power plant to be assembled on earth and operated on the moon is presented. The two principal design objectives are reliability and high specific power. Wherever there is an incompatibility between these two objectives, the decision favors reliability. The design is based on the premise that the power plant must be designed on the basis of current technology and with a minimum amount of research and development. The principal components consist of a fast reactor in a dire… more

Modifications for the Str Fuel Recovery Process

Description: In a program directed toward the optimization of the process chemistry of the STR hydrofluoric acid method of reprocessing zirconium-uranium alloy fuels, it was shown that the process can be modified to dissolve homogeneously fuels of higher uranium content by either hydrogen peroxide oxidation or dilution of the dissolver solution. Rate of corrosion of Monel was acceptable with both methods of dissolution. Phase and stability studies of the solvent extraction feed and waste solutions indicated… more
