Geothermal well log interpretation midterm report

Description: Reservoir types are defined according to fluid phase and temperature, lithology, geologic province, pore geometry, and salinity and fluid chemistry. Improvements are needed in lithology and porosity definition, fracture detection, and thermal evaluation for more accurate interpretation. Further efforts are directed toward improving diagnostic techniques for relating rock characteristics and log response, developing petrophysical models for geothermal systems, and developing thermal evaluation techniques. The Geothermal Well Log Interpretation study and report has concentrated only on hydrothermal geothermal reservoirs. Other geothermal reservoirs (hot dry rock, geopressured, etc.) are not considered.

Geothermal well log interpretation state of the art. Final report

Description: An in-depth study of the state of the art in Geothermal Well Log Interpretation has been made encompassing case histories, technical papers, computerized literature searches, and actual processing of geothermal wells from New Mexico, Idaho, and California. A classification scheme of geothermal reservoir types was defined which distinguishes fluid phase and temperature, lithology, geologic province, pore geometry, salinity, and fluid chemistry. Major deficiencies of Geothermal Well Log Interpretation are defined and discussed with recommendations of possible solutions or research for solutions. The Geothermal Well Log Interpretation study and report has concentrated primarily on Western US reservoirs. Geopressured geothermal reservoirs are not considered.

Implementation of ANSI 13.36 - Radiation Safety Training for Workers

Description: ''Radiation Safety Training for Workers'' (ANSI 13.36) specifies a process for developing and implementing radiation safety training using performance-based concepts. In general, radiation safety training includes radiological safety policies, fundamental radiological controls, and the technical functions of specific facilities. Actual training, however, can vary significantly from one site to another, depending on the requirements and potential risks associated with the specific work involved. Performance-based training focuses on the instruction and practices required to develop job-related knowledge, skills, and abilities, rather than on simply prescribing training content and objectives. The Health Physics Society Standards Committee (HPSSC) working group recommended performance-based training, as opposed to a broad training program with prescribed performance objectives, for two main reasons: (1) the wide range of radiological workers to be trained and (2) the concern that a prescriptive program (i.e., 40 hours of training) could be misapplied. In addition, the working group preferred that the scope and depth of training be based on specific hazards and the magnitude of risk posed by those hazards. The group also proposed that passing scores be based on specified goals and the characteristics of test questions used. For instance, where passing scores are established (e.g., multiple-choice exams), they should be based on an analysis of the test questions rather than simply an arbitrary passing score. This standard is not intended to replace regulatory or contractual training requirements that establish minimum objectives, topics, class duration, or passing scores. Nor does it address radiation safety training received as part of an academic program of study. Such individuals would still require site-specific and on-the-job training for certain tasks.

Interactive, Computer-Based Training Program for Radiological Workers

Description: Lawrence Livermore National Laboratory (LLNL) is redesigning its Computer-Based Training (CBT) program for radiological workers. The redesign represents a major effort to produce a single, highly interactive and flexible CBT program that will meet the training needs of a wide range of radiological workers--from researchers and x-ray operators to individuals working in tritium, uranium, plutonium, and accelerator facilities. The new CBT program addresses the broad diversity of backgrounds found at a national laboratory. When a training audience is homogeneous in terms of education level and type of work performed, it is difficult to duplicate the effectiveness of a flexible, technically competent instructor who can tailor a course to the express needs and concerns of a course's participants. Unfortunately, such homogeneity is rare. At LLNL, they have a diverse workforce engaged in a wide range of radiological activities, from the fairly common to the quite exotic. As a result, the Laboratory must offer a wide variety of radiological worker courses. These include a general contamination-control course in addition to radioactive-material-handling courses for both low-level laboratory (i.e., bench-top) activities as well as high-level work in tritium, uranium, and plutonium facilities. They also offer training courses for employees who work with radiation-generating devices--x-ray, accelerator, and E-beam operators, for instance. However, even with the number and variety of courses the Laboratory offers, they are constrained by the diversity of backgrounds (i.e., knowledge and experience) of those to be trained. Moreover, time constraints often preclude in-depth coverage of site- and/or task-specific details. In response to this situation, several years ago LLNL began moving toward computer-based training for radiological workers. Today, that CBT effort includes a general radiological safety course developed by the Department of Energy's Hanford facility and a contamination-control program developed by LLNL. A comprehensive study guide and a post-training practical exam supplement the ...
