Design of a hot clamp for small diameter LMFBR piping

Description: In order to evaluate the feasibility of using a strap-type clamp on breeder reactor small diameter piping, a series of analyses were conducted to determine the thermal and mechanical stresses induced in the pipe by the clamp. The effect of using a thin layer of insulation of varying thickness between the pipe and clamp was also investigated. A thermal analysis of the pipe and clamp was conducted for each thermal transient rate. Various insulation values ranging from metal-to-metal condition to perfect insulation between the pipe and clamp were analyzed to determine the effect of insulating the pipe from the clamp. An axisymmetric finite element model was used to determine the axial thermal and stress patterns.

Detection of pulsed, bremsstrahlung-induced, prompt neutron capture gamma-rays with HPGe detector

Description: The Idaho National Engineering Laboratory (INEL) is developing a novel photoneutron-based nondestructive evaluation technique which uses a pulsed, high-energy (up to 8-MeV) electron accelerator and gamma-ray spectrometry. Highly penetrating pulses of bremsstrahlung photons are produced by each pulse of electrons. Interrogating neutrons are generated by the bremsstrahlung photons interacting within a photoneutron source material. The interactions of the neutrons within a target result in the emission of elemental characteristic gamma-rays. Spectrometry is performed by analyzing the photoneutron-induced prompt gamma-rays acquired between accelerator pulses with a unique, high-purity germanium (HPGe) gamma-ray detection system using a modified transistor reset preamplifier. The detection system, the experimental configuration, and the accelerator operation used to characterize the detection system performance are described. Using a 6.5 MeV electron accelerator and a beryllium metal photoneutron source, gamma-ray spectra were successfully acquired for Al, Cu, polyethylene, NaC1, and depleted uranium targets as soon as 30 {mu}s after each bremsstrahlung (or x-ray) flash.

Improving tag/seal technologies: the vulnerability assessment component

Description: The Department of Energy (DOE), specifically the Office of Nonproliferation and National Security, has sponsored the development of numerous tag and seal technologies for high-security/high-valued applications. One important component in this technology development effort has been the continuous integration of vulnerability assessments. The Idaho National Engineering Laboratory (INEL) has been the lead laboratory for vulnerability assessments of fiber-optic-based tag/seal technologies. This paper presents a brief historical overview and the current status of the DOE high-security tag/seal development program and discusses INEL`s adversarial role and assessment philosophy. Verification testing criteria used to define ``successful`` tampering attempts/attacks are discussed. Finally, the advantages of integrating a vulnerability assessment into the development of commercial security tag/seals are presented.

CO/sub 2/ and the world energy system: The role of nuclear power

Description: The greenhouse effect, and other transnational and global environment, health and safety issues, require energy system planning on an international scale. Consideration of equity between nations and regions, particularly between the industrialized and developing countries, is an essential ingredient. For the immediate future, the next several decades at least, fossil fuels will remain the predominant energy sources. More efficient use of energy seems to be the only feasible strategy for the near to mid-term to provide growing energy services for the world economy while moderating the increasing demand for fossil fuels. In the longer term, nonfossil sources are essential for a sustainable world energy system, and nuclear power can play an important, if not dominant, role. The challenge is to design and implement a safe and economic nuclear power world enterprise which is socially acceptable and is complimentary to other nonfossil sources. The elements of such an enterprise seem clear and include: much safer reactors, preferably passively safe, which can be developed at various scales; development of economic resource extension technologies; effective and permanent waste management strategies; and strengthened safeguards against diversion of nuclear materials to weapons. All of these elements can best be developed as cooperative international efforts. In the process, institutional improvements are equally as important as technological improvements; the two must proceed hand-in-hand. 14 refs., 4 figs., 1 tab.

Lysimeters at the Hanford Site: present use and future needs

Description: Lysimeters have been built and used at the Hanford Site for a variety of reasons, including the assessment of recharge (drainage) rates, biointrusion studies, the development of shallow-land burial monitoring and measurement methods, radionuclide transport studies, evapotranspiration studies, and field-scale waste-form leaching tests. A common feature of lysimeters is that they provide a way either to directly measure or to estimate water balance parameters such as soil-water storage changes, evapotranspiration, and drainage for a given site. The number of water balance parameters and the precision with which they can be measured vary depending on the design features of the lysimeter. In this report we describe key design features of the six major lysimeters facilities at Hanford and the types of data available from them. We also address the deficiencies of the present facilities for adequately determining recharge rates and propose additional facilities to evaluate protective barrier systems and arid-land water dynamics. 44 refs., 9 figs., 4 tabs.

Evaluation of continuous oxydesulfurization processes. Final technical report, September 1979-July 1981

Description: Three processes developed by Pittsburgh Energy Technology Center (PETC), Ledgemont Laboratories, and Ames Laboratories for the oxydesulfurization of coal were evaluated in continuous processing equipment designed, built, and/or adapted for the purpose at the DOE-owned Multi-Use Fuels and Energy Processes Test Plant (MEP) located at TRW's Capistrano Test Site in California. The three processes differed primarily in the chemical additives (none, sodium carbonate, or ammonia), fed to the 20% to 40% coal/water slurries, and in the oxygen content of the feed gas stream. Temperature, pressure, residence time, flow rates, slurry concentration and stirrer speed were the other primary independent variables. The amount of organic sulfur removed, total sulfur removed and the Btu recovery were the primary dependent variables. Evaluation of the data presented was not part of the test effort.

A multigrid method for variable coefficient Maxwell's equations

Description: This paper presents a multigrid method for solving variable coefficient Maxwell's equations. The novelty in this method is the use of interpolation operators that do not produce multilevel commutativity complexes that lead to multilevel exactness. Rather, the effects of multilevel exactness are built into the level equations themselves--on the finest level using a discrete T-V formulation, and on the coarser grids through the Galerkin coarsening procedure of a T-V formulation. These built-in structures permit the levelwise use of an effective hybrid smoother on the curl-free near-nullspace components, and these structures permit the development of interpolation operators for handling the curl-free and divergence-free error components separately, with the resulting block diagonal interpolation operator not satisfying multilevel commutativity but having good approximation properties for both of these error components. Applying operator-dependent interpolation for each of these error components leads to an effective multigrid scheme for variable coefficient Maxwell's equations, where multilevel commutativity-based methods can degrade. Numerical results are presented to verify the effectiveness of this new scheme.

X-ray Computed Tomography and Stereo-Radiographic Inspection Results of the Office of Emergency Response (NA-42) Test Object

Description: This report has documented the worked performed in the x-ray computed tomographic and stereo-radiographic inspection of the NA-42 test object. We have described the method SRNL used to obtain high resolution (80 micron) images of the test object using PSL plates. The PSL plates are an excellent alternative to x-ray film and they eliminate the need for the wet chemistry processing and the disposal of the chemical wastes. The PSL plates were used to provide an overall panoramic view of the large test object. These images were useful in planning other inspection techniques. In addition, a customized digital radiography system with an 85-inch wide field-of-view was assembled to support the data collection for computed tomography. The trade-offs between resolution and data collection and CT reconstruction time were explained in detail. The CT projections and reconstructed slices of the test object were included in the report as static images and ''movies'' were also provided on the attached CD-ROM. The combination of the projections and the CT slices provide a thorough understanding of the internal structure of the device. The full projection CT results were also used as a ''bench mark'' for other techniques investigated during this work, such as the limited view CT and stereo-radiographic work. The limited view CT results were obtained by parsing the full data set into subsets with larger angular intervals and thus fewer projections. These subsets were then processed with the CT reconstruction software. The results of reconstructions from 720 down to 10 projections were compared. Based on these results, we concluded that 20 to 30 projections were adequate. These results were then used to predict the required data collection time for higher resolution systems. It was concluded that from a data collection time basis, limited view CT could provide the desired resolution (1 mm) within ...

Corrosion and Creep of Candidate Alloys in High Temperature Helium and Steam Environments for the NGNP

Description: This project aims to understand the processes by which candidate materials degrade in He and supercritical water/steam environments characteristic of the current NGNP design. We will focus on understanding the roles of temperature, and carbon and oxygen potential in the 750-850 degree C range on both uniform oxidation and selective internal oxidation along grain boundaries in alloys 617 and 800H in supercritical water in the temperature range 500-600 degree C; and examining the application of static and cyclic stresses in combination with impure He environments in the temperature rang 750-850 degree C; and examining the application of static and cyclic stresses in combination with impure He environments in the temperature range 750-850 degree C over a range of oxygen and carbon potentials in helium. Combined, these studies wil elucidate the potential high damage rate processes in environments and alloys relevant to the NGNP.

A parallel implementation of kriging with a trend

Description: This paper describes the parallelization of the GSLIB ktb3dm code. The code is parallelized using the message passing paradigm, Parallel Virtual Machine (PVM), under a Multiple Instructions, Multiple Data (MIMD) architecture. The code performance is analyzed using different grid sizes of 5x5x1, 50x50x1, 100x100x1 and 500x500x1 with 1, 2, 4, 8 and in some cases 16 processors on the Cray T3D supercomputer. The parallelization effort focused on the main kriging do loop. The results confirm that there is a substantial benefit to be derived in terms of CPU time savings (or execution speed) by using the parallel version of the code, especially when considering larger grids. Additionally, speed-up and scalability analyses show that actual speed-up is close to theoretical, while the code scales appropriately within the 1 to 16 processor range tested. The kriging of a quarter-million grid cell system fell from over 9 CPU minutes on one Cray T3D processor to about 1.25 CPU minutes on 16 processors on the same machine.
