Navy Nuclear Aircraft Carrier (CVN) Homeporting at Mayport: Background and Issues for Congress

Description: This report provides background information and issues for Congress on the Navy's proposal to homeport a nuclear-powered aircraft carrier (CVN) at Mayport, Florida. Transferring a CVN from Norfolk, Virginia, to Mayport would also shift the local economic activity associated with homeporting a CVN, which some sources estimate as being worth hundreds of millions of dollars per year.

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

Description: This report provides background information and presents potential issues for Congress concerning the Navy's ship force-structure goals and shipbuilding plans. The planned size of the Navy, the rate of Navy ship procurement, and the prospective affordability of the Navy's shipbuilding plans have been matters of concern for the congressional defense committees for the past several years. Decisions that Congress makes on Navy shipbuilding programs can substantially affect Navy capabilities and funding requirements, and the U.S. shipbuilding industrial base.

Navy Nuclear-Powered Surface Ships: Background, Issues, and Options for Congress

Description: This report discusses the possibility of increasing the number of Navy surface ships powered by nuclear energy, including the Navy's planned CG(X) cruiser. The report explores a 2006 Navy study that discusses budget considerations, the cost of a nuclear-powered ship compared to a ship powered by crude oil, and other suggestions relating to this proposed expansion. The overall report has a specific emphasis on the planned CG(X) cruiser, and how the implementation of this cruiser may be delayed by current budget proposals.

Navy Aegis Ballistic Missile Defense (BMD) Program: Background and Issues for Congress

Description: This report discusses the Aegis ballistic missile defense (BMD) program. Under current Missile Defense Agency (MDA) and Navy plans, the number of BMD-capable Navy Aegis ships is schedule to grow from 20 at the end of FY2010 to 38 at the end of FY2015. This report discusses the concerns some have over BMD expansion, as well as BMD funding issues.

Supreme Court Nominee Elena Kagan: Defamation and the First Amendment

Description: This report discusses prior writings by Supreme Court nominee Elena Kagan on the interaction of defamation law and the First Amendment of the Constitution. It is based on two articles on defamation law written by Kagan during her academic career at the University of Chicago Law School and the Harvard Law School. The most recent of these articles is from 2000, and Kagan has not revisited this topic in any published writings since then. Thus, these two articles appear to represent her most extensive examination of the interaction between the First Amendment and defamation law.

Microstructural development in waste form alloys cast from irradiated cladding residual from the electrometallurgical treatment of EBR-II spent fuel.

Description: A metallic waste form alloy that consists primarily of stainless steel and zirconium is being developed by Argonne National Laboratory to contain metallic waste constituents that are residual from an electrometallurgical treatment process for spent nuclear fuel. Ingots have been cast in an induction furnace in a hot cell using actual, leftover, irradiated, EBR-II cladding hulls treated in an electrorefiner. The as-cast ingots have been sampled using a core-drilling and an injection-casting technique. In turn, generated samples have been characterized using chemical analysis techniques and a scanning electron microscope equipped with energy dispersive and wavelength-dispersive spectrometers. As-cast ingots contain the predicted concentration levels of the various constituents, and most of the phases that develop are analogous to those for alloys generated using non-radioactive surrogates for the various fission products.

Antiproton acceleration in the Fermilab Main Injector using 2.5 MHz (H=28) and 53 MHz (H=588) rf systems

Description: During the Run II era at Fermilab, the Recycler stores antiprotons at 8 GeV and the Main Injector accelerates the antiprotons and the protons from 8 GeV to 150 GeV for Tevatron injection. The Recycler injects antiprotons to the Main Injector in 2.5 MHz rf buckets. This report presents an acceleration scheme for the antiprotons that involves a slow ramp with initial 2.5 MHz acceleration and subsequent fast acceleration with 53 MHz rf system. Beam acceleration and rf manipulation with space charge and beam loading effects are simulated using the longitudinal simulation code ESME. Simulation suggests that one can expect about 15% emittance growth for the entire acceleration cycle with beam loading compensations. Preliminary experimental results with proton beam will also be presented.

Weldability Comparison of Tritium-Charged-and -Aged 304 and 316LN Stainless Steels

Description: Measurement of the effects of helium (from tritium decay) on the weldability of Types 304 and ITER Grade 316LN stainless steel demonstrated the inherent complexities in designing and conducting an experimental program using tritium-charged-and-aged materials to simulate the effects of irradiation-induced helium on weld behavior. Differences in microstructure, surface condition and alloy chemistry are known to play key roles in tritium absorption and distribution and thus have direct effects on the subsequent 3He production and distribution. The helium embrittlement cracking produced in 0.5 in. (12.7 mm) thick 304 and 316LN plates that were tritium-charged in the same container and subsequently welded with gas metal arc, low heat input weld overlays and gas tungsten arc stringer beads, varied markedly. For example, the porosity in the weld beads was much higher in the 304 plate than in the 316LN plate. Additionally, crack measurements from weld cross-sections revealed more extensive intergranular cracking in the heat-affected zones of welds on the 304 plate when compared to the 316LN plate. However, the differences between the two types of stainless steel may not be a result of differences in the resistance to helium embrittlement cracking, but may be due to initial tritium concentration differences developed in the as-charged plates. Further work is necessary to identify the reasons for the apparent plate to plate variation in tritium/helium content and to demonstrate the similarities (or differences) between Types 304 and ITER grade 316LN stainless steel.
