In one mode of operation of an electron ring accelerator (ERA), at the end of compression rings are slowly moved through the radial integral betatron resonance Q{sub r} = 1. Although the coherent radial oscillation frequency of the ring as a whole remains below unit, the oscillation frequencies of individual electron are (incoherently) caused to pass through the resonance because of the additional focusing from ions trapped in the ring. In this paper the effect of field errors on ring major and minor radii is evaluated--theoretically--for the cases in which the spread in the square of the electron oscillation frequency ({Delta}{sup 2}) is (a) much larger and (b) much smaller than the contribution to the square of the oscillation frequency from the ions ({Lambda}{sup 2}). It is shown that for the ERA, where case (b) applies, the increase in ring minor dimensions, for given field errors and rate of resonance crossing, is less than in case (a) by a factor of ({Delta}/{Lambda}){sup 2}. Numerical examples show that the degradation of ring quality in case (b) should, with suitable attention to the design and construction of the ERA apparatus, be acceptably small.

The effects of variation in source and medium properties upon near- and far-field spectra for elastic waves are examined theoretically by considering spherical wave propagation in unbounded elastic media. This type of analysis, although idealized, provides insight into the relative effects of the various source and medium parameters on both tamped and decoupled explosions. It also provides a basis for interpreting both field and laboratory experimental data obtained during spherical wave propagation in real media. In this paper I attempt to unify the work that has been done on spherical wave propagation in elastic media. I present the results in nondimensional forms, in hopes that others may find these forms of the solutions useful and some of the conclusions, based upon my parameter studies, enlightening. Also included is a discussion of some of the limitations of the theory and examples of applications of the spherical wave propagation theory in real media.

An annotated bibliography is presented which was compiled while searching the literature for information on fluid inclusions in salt for the Nuclear Regulatory Commission's study on the deep-geologic disposal of nuclear waste. The migration of fluid inclusions in a thermal gradient is a potential hazard to the safe disposal of nuclear waste in a salt repository. At the present time, a prediction as to whether this hazard precludes the use of salt for waste disposal can not be made. Limited data from the Salt-Vault in situ heater experiments in the early 1960's (Bradshaw and McClain, 1971) leave little doubt that fluid inclusions can migrate towards a heat source. In addition to the bibliography, there is a brief summary of the physical and chemical characteristics that together with the temperature of the waste will determine the chemical composition of the brine in contact with the waste canister, the rate of fluid migration, and the brine-canister-waste interactions.

During normal operation the quantity of radionuclides present in K reactor effluent, when diluted in the river, produce concentrations of radioactivity that are, on the average, a few percent of the limiting values of present government standards (I0CFR20). The radioactive concentrations in the effluent prior to dilution in the river are a few times the upper limit of the present government standards (10CFR20). This paper will address itself to the assessment of the radiological implications of the production, disposal, and future release of radioactive material attendant with the ground disposal of the K reactor effluent. Particular emphasis will be placed on the future release, to uncontrolled areas, and of stored radioactive material as a result of a ``once in a century`` accident.

The objective of the effort reported herein is to develop a controls design for teh NERVA engine in the cooldown phase of operation which meets te performance requirements of References 1 and 6. This memorandum documents the preliminary cooldown controls functional design and shows the status of the design effort to date rather than the completion of this effort. The completion of this effort as outlined in the work statements will culminate in a first cut design which may not be optimized and which will not include any malfunction analysis.

This study identifies codes, standards, and regulatory requirements for developing design criteria for high-level waste (HLW) canisters for commercial operation. It has been determined that the canister should be designed as a pressure vessel without provision for any overpressure protection type devices. It is recommended that the HLW canister be designed and fabricated to the requirements of the ASME Section III Code, Division 1 rules, for Code Class 3 components. Identification of other applicable industry and regulatory guides and standards are provided in this report. Requirements for the Design Specification are found in the ASME Section III Code. It is recommended that design verification be conducted principally with prototype testing which will encompass normal and accident service conditions during all phases of the canister life. Adequacy of existing quality assurance and licensing standards for the canister was investigated. One of the recommendations derived from this study is a requirement that the canister be N stamped. In addition, acceptance standards for the HLW waste should be established and the waste qualified to those standards before the canister is sealed. A preliminary investigation of use of an overpack for the canister has been made, and it is concluded that the use of …
