A 200 MHz 35 MW Multiple Beam Klystron for Accelerator Applications Final Report

Description: Calabazas Creek Research, Inc. (CCR) performed initial development of a compact and reliable 35 MW, multiple beam klystron (MBK) at 200 MHz with a pulse length of 0.125 ms and a 30 Hz repetition rate. The device was targeted for acceleration and ionization cooling of a muon collider, but there are several other potential applications in this frequency range. The klystron uses multiple beams propagating in individual beam tunnels to reduce space charge and allow reduction in the accelerating vol… more

The 2010 Oil Spill: Criminal Liability Under Wildlife Laws

Description: In April 2010 an explosion occurred on an oil rig in the Gulf of Mexico, reportedly killing 11 people, and, according to federal experts, causing the worst oil spill in U.S. history. Millions of barrels of oil are believed to have leaked into the Gulf of Mexico. As the oil spreads, the implications for harm to wildlife grow. The United States has many laws that protect wildlife from harm. This report discusses three: the Endangered Species Act, the Marine Mammal Protection Act, and the Migrator… more

Ab Initio Enhanced calphad Modeling of Actinide-Rich Nuclear Fuels

Description: The process of fuel recycling is central to the Advanced Fuel Cycle Initiative (AFCI), where plutonium and the minor actinides (MA) Am, Np, and Cm are extracted from spent fuel and fabricated into new fuel for a fast reactor. Metallic alloys of U-Pu-Zr-MA are leading candidates for fast reactor fuels and are the current basis for fast spectrum metal fuels in a fully recycled closed fuel cycle. Safe and optimal use of these fuels will require knowledge of their multicomponent phase stability and… more

Acoustic Telemetry Evaluation of Juvenile Salmonid Passage and Survival Proportions at John Day Dam, 2009

Description: The overall purpose of the acoustic telemetry study at JDA during 2009 was to determine the best configuration and operation for JDA prior to conducting BiOp performance standard tests. The primary objective was to determine the best operation between 30% and 40% spill treatments. Route-specific and JDA to TDA forebay survival estimates, passage distribution, and timing/behavior metrics were used for comparison of 30% to a 40% spill treatments. A secondary objective was to evaluate the performa… more

Adding a MOAB Geometry Interface to SHARP Structural Mechanics

Description: The authors briefly summarize the development of, and test experience with, an initial data interface between the structural mechanics code Diablo and the SHARP reactor simulation system data hub MOAB. That interface has been exercised both to write MOAB databases from Diablo, and then also to use such a database to read in part of a simulation definition for a subsequent Diablo execution. All enhancements are integrated into the central Diablo source repository. The SHARP software system for a… more
