Studies of Metallic Uranium Fuel and Mixed Moderator Systems in Pressurized Water Reactors

Description: This report is a summary of work performed for the U.S. Arms Control and Disarmament Agency under Contract AC7NC122. The work is directly related to the Agency effort to examine potential alternative fuel cycles that might enhance uranium resource utilization, minimize plutonium production, and reduce the need for reprocessing of spent light water reactor (LWR) fuel. Two alternative fuel cycles are examined in this report: (1) the possible use of metallic fuel in LWR fuel elements, and (2) the use of mixture of light water and heavy water as coolant/moderator in a pressurized water reactor. In both cases, calculations of survey nature were performed to determine the basic characteristics of the two cycles -- reactivity, fuel depletion isotopics, uranium resource requirements and plutonium production. Results of these calculations are presented, together with a discussion of the state-of-the-art and design considerations relative to the utilization of metallic fuel.

Fuel performance improvement program. Quarterly progress report, January--March 1978. [BWR; PWR]

Description: The Fuel Performance Improvement Program has as its objective the identification and demonstration of fuel concepts with improved power ramp performance. Improved fuels are being sought to allow reduction or elimination of fuel related operating guidelines on nuclear power plants such that the fuel may be power maneuvered within the rates allowed by the system technical specifications. The program contains a combination of out-of-reactor studies, in-reactor experiments and in-reactor demonstrations. Fuel concepts initially being considered include annular pellets, cladding internally coated with graphite and packed-particle fuels. The performance capability of each concept will be compared to a reference fuel of contemporary pellet design by irradiations in the Halden Boiling Water Reactor. Fuel design and process development is being completed and fuel rod fabrication will begin for the Halden test rods and for the first series of in-reactor experiments. The in-reactor demonstrations are being performed in the Big Rock Point reactor to show that the concepts pose no undue risk to commercial operation. Additional concepts may be considered as the result of a state-of-the-technology review of fuel-cladding interaction and assessment of fuel concepts and the out-of-reactor studies. The results of the program will be used to establish the technical bases for design of fuels with improved power ramp performance.

Gas core reactors for actinide transmutation and breeder applications. Annual report

Description: This work consists of design power plant studies for four types of reactor systems: uranium plasma core breeder, uranium plasma core actinide transmuter, UF6 breeder and UF6 actinide transmuter. The plasma core systems can be coupled to MHD generators to obtain high efficiency electrical power generation. A 1074 MWt UF6 breeder reactor was designed with a breeding ratio of 1.002 to guard against diversion of fuel. Using molten salt technology and a superheated steam cycle, an efficiency of 39.2% was obtained for the plant and the U233 inventory in the core and heat exchangers was limited to 105 Kg. It was found that the UF6 reactor can produce high fluxes (10 to the 14th power n/sq cm-sec) necessary for efficient burnup of actinide. However, the buildup of fissile isotopes posed severe heat transfer problems. Therefore, the flux in the actinide region must be decreased with time. Consequently, only beginning-of-life conditions were considered for the power plant design. A 577 MWt UF6 actinide transmutation reactor power plant was designed to operate with 39.3% efficiency and 102 Kg of U233 in the core and heat exchanger for beginning-of-life conditions.

Gamma spectroscopic examination of Peach Bottom HTGR core components

Description: During discharge of Core 2 from the Peach Bottom High-Temperature Gas-Cooled Reactor (HTGR), 55 driver elements, 21 test elements, three reflector elements, and one control rod with sleeve were axially gamma scanned with a high-resolution Ge(Li) detector. The purpose of the exercise was to determine fission product distributions for use in burnup calculations, power profile determinations, and fission product release and redistribution studies. The results showed that the predicted and measured burnups had a +-7 percent root mean square deviation on an element-to-element basis and were within +-0.7 percent (1 sigma) on a core average basis. The element-to-element variation of +-7 percent is within the generally stated +-3 percent to 8 percent accuracy for nuclear predictions.

Energy: options for the future. Curriculum development project for high school teachers. Final report. [Packet]

Description: Recent state and regional energy crises demonstrate the delicate balance between energy systems, the environment, and the economy. Indeed, the interaction between these three elements of society is very complex. This project develops curriculum materials that would better provide students with an understanding and awareness of fundamental principles of energy supply, conversion processes, and utilization now and in the future. The project had two specific objectives: to transfer knowledge of energy systems, analysis techniques, and advanced technologies from the energy analyst community to the teacher participants; and to involve teachers in the preparation of modular case studies on energy issues for use within the classroom. These curriculum modules are intended to enhance the teacher's ability to provide energy-related education to students within his or her own academic setting. The project is organized as a three-week summer program, as noted in the flyer (Appendix A). Mornings are spent in seminars with energy and environmental specialists (their handout lecture notes are included as Appendix B); afternoons are devoted to high school curriculum development based on the seminar discussions. The curriculum development is limited to five areas: conservation, electricity demand scheduling, energy in the food system, new technologies (solar, wind, biomass), and environment. Appendix C consists of one-day lession plans in these areas.

Unified connected theory of few-body reaction mechanisms in N-body scattering theory

Description: A unified treatment of different reaction mechanisms in nonrelativistic N-body scattering is presented. The theory is based on connected kernel integral equations that are expected to become compact for reasonable constraints on the potentials. These equations can be formulated for any important set of asymptotic channels. The operators T/sub +-//sup ab/(A) are approximate transition operators that describe the scattering proceeding through an arbitrary reaction mechanism A. These operators are uniquely determined by a connected kernel equation and satisfy an optical theorem consistent with the choice of reaction mechanism. Connected kernel equations relating T/sub +-//sup ab/(A) to the full T/sub +-//sup ab/ allow correction of the approximate solutions for any ignored process to any order. This theory gives a unified treatment of all few-body reaction mechanisms with the same dynamic simplicity of a model calculation, but can include complicated reaction mechanisms involving overlapping configurations where it is difficult to formulate models. 1 figure.

Empirical limitations of energy dissipation in /sup 252/Cf(sf)

Description: Limitations for the energy dissipated in the spontaneous fission of /sup 252/Cf were studied on the basis of the experimental fragment kinetic energies, neutron and ..gamma.. data and the calculated (static) potential energies of the fragments. Upper bounds for the dissipated energy are obtained by restricting the parameter space of the fissioning system to the domain which is compatible with the experimental post-scission data, and by computing the maximum energy available in this domain for dissipation. No assumptions were made about the fission dynamics or the dissipation mechanism. A numerical evaluation was performed for 19 pairs of fragments in /sup 252/Cf(sf), taking into account spheroidal fragment shapes with diffuse surface, nuclear interaction and Coulomb excitation effects. The energy available for internal excitation at scission is found to be small (< or = to 10 MeV). An analysis of the uncertainties entering into this result shows that high dissipation in /sup 252/Cf(sf) is incompatible with the existing experimental data unless peculiar fragment shapes are assumed. Upper bounds are also given for the fragment deformations. The hypothesis of scission, minimum potential energy at the influence of fragment effects, and the relevance of data from ternary fission are discussed.
