At the end of Phase I, ABI will deliver a working "subscale" power module which runs on diesel fuel and has an output of approximately 25 horsepower at 3600 RPM. The overall size, exclusive of fuel pump, cooling, and 011 tank, will be approximately the size and shape of a roll of kitchen paper towels, about 15 cm diameter and less than 40 cm long, and less that 20 lbs. weight. Phase II will develo ...

Preliminary studies have demonstrated the feasibility of a novel computational scheme which will address critical errors in the present methodology of source localization. These studies will also make it feasible to obtain source location and pattern of activity based on realistic models of the head constructed from MRI or CT imaging modalities. Potential clinical applications include functional i ...

THE PURPOSE OF PHASE I OF THIS RESEARCH PROJECT IS TO CRITICALLY REVIEW THE EXISTING COMPUTERIZED EOP SYSTEMS FOR BOTH PWR AND BWR PLANTS, DEVELOPED BY VARIOUS NATIONAL AND INTERNATIONAL ORGANIZATIONS TO FULLY UNDERSTAND THEIR ADVANTAGES, DISADVANTAGES AND LIMITATIONS IN TERMS OF THEIR IMPACT ON OPERATORS PERFORMANCE AND RELIABILITY AND RECOMMEND ONE SYSTEM OR A COMPOSITE OF SEVERAL SYSTEMS, BEFOR ...

COMPUTERIZED DATA COLLECTION DEVICES EXIST AND ARE BEING USED IN VARIOUS APPLICATIONS AT SOME NPPS FOR SYSTEMS AND EQUIPMENT NOT INSTRUMENTED IN THE CONTROL ROOM. HOWEVER, CURRENT APPLICATIONS IN THE NUCLEAR POWER INDUSTRY ARE RATHER SPORADIC AND NOT EXPLOITING THE FULL POTENTIAL OF THE TECHNOLOGY. FOR EXAMPLE, SEVERAL DIFFERENT NPPS USE SUCH SYSTEMS FOR SINGLE- PURPOSES SUCH AS TRENDS IN EQUIPMEN ...

THIS PROJECT INVESTIGATES A NEW TYPE OF HIGH Q RESONANT STRUCTURE, WHICH HAS RECENTLY BEEN DEMONSTRATED, TO DEVELOP HIGH GRADIENT, SUPERCONDUCTING ACCELERATOR CAVITIES. BASED ON THE CONCEPT OF A PHOTONIC BAND GAP (PBG) RESONATOR, THESE NEW STRUCTURES ARE PHYSICALLY SIGNIFICANTLY DIFFERENT FROM THE RESONANT CAVITIES CURRENTLY USED IN NORMAL SUPERCONDUCTING DEVICES. A RESONANT MODE SUITABLE FOR ACCE ...

THE EFFECTIVENESS OF THE NEUTRAL PARTICLE BEAM (NPB) MISSILE DEFENSE SYSTEM DEPENDS ON THE SUCCESSFUL ACCELERATION OF HIGH BRIGHTNESS H ION BEAMS AT HIGH CURRENTS WITH CONTINOUS WAVE (CW) OPERATION. PRESENT BASELINE DESIGNS FOR THESE POWERFUL LINAC SYSTEMS INCLUDE ONE OR MORE STAGES OF BEAM COMBINATION (FUNNELING) INTO LATER STAGES OF THE LINAC TO OVERCOME THE CURRENT LIMITATIONS OF THE INITIAL LI ...

The primary goal of this Phase I design study is to develop the design of an accelerator-based neutron source for clinical boron neutron capture therapy (BNCT) using the compact radio-frequency quadruple (RFQ) linear accelerator. This accelerator design study will be completed in collaboration with the Brain Tumor Research Center at the University of California in San Francisco (UCSF). The acceler ...

THE USE OF THE RADIO FREQUENCY SUPERCONDUCTING ION LINACS HAS GROWN STEADILY OVER THE PAST 15 YEARS, PRIMARILY FOR APPLICATIONS IN NUCLEAR AND ATOMIC PHYSICS WHERE FLEXIBILITY N ION SPECIES AND ENERGY ARE REQUIRED. THIS TECHNOLOGY CONTINUES TO BE ACTIVELY DEVELOPED AT SEVERAL LABORATORIES WORLDWIDE. A RECENT DEVELOPMENT AT THE ARGONNE TANDEM LINAC ACCELERATOR SYSTEM (ATLAS) FOR THE NEW POSITIVE IO ...

The objective of the program is to investigate the use of parametric x-ray radiation (PXR) as a tunable, quasimonochromatic x-ray source for mammography. PXR is generated by placing natural, synthetic crystals, or multilayer structures into the path of a relativistic electron beam. The virtual photons associated with the fields of the electrons are Bragg reflected by the periodic crystal lattice a ...
