Nuclear Weapons: National Nuclear Security Administration Needs to Ensure Continued Availability of Tritium for the Weapons Stockpile

Description: A letter report issued by the Government Accountability Office with an abstract that begins "The National Nuclear Security Administration's (NNSA) Tritium Readiness Program aims to establish an assured domestic source of tritium--a key isotope used in nuclear weapons--in order to maintain the U.S. nuclear weapons stockpile. Because tritium decays at a rate of 5.5 percent annually, it must be periodically replenished in the stockpile. However, since 2003, NNSA's efforts to produce tritium have b… more

Nuclear Weapons: Status of Planning for Stockpile Life Extension

Description: Correspondence issued by the General Accounting Office with an abstract that begins "In the late 1980's, the Department of Energy's (DOE) Office of Defense Programs altered its mission. Instead of designing, testing, and building new nuclear weapons, the Office began to focus on maintaining the safety and reliability of the nation's nuclear weapons stockpile indefinitely without nuclear testing. This mission is performed by the National Nuclear Security Administration (NNSA), a semiautonomous a… more

National Certification Methodology for the Nuclear Weapons Stockpile

Description: Lawrence Livermore and Los Alamos National Laboratories have developed a common framework and key elements of a national certification methodology called Quantification of Margins and Uncertainties (QMU). A spectrum from senior managers to weapons designers has been engaged in this activity at the two laboratories for on the order of a year to codify this methodology in an overarching and integrated paper. Following is the certification paper that has evolved. In the process of writing this pap… more

Foundations for Improvements to Passive Detection Systems - Final Report

Description: This project explores the scientific foundation and approach for improving passive detection systems for plutonium and highly enriched uranium in real applications. Sources of gamma-ray radiation of interest were chosen to represent a range of national security threats, naturally occurring radioactive materials, industrial and medical radiation sources, and natural background radiation. The gamma-ray flux emerging from these sources, which include unclassified criticality experiment configurati… more

Strontium Isotopic Composition of Paleozoic Carbonate Rocks in the Nevada Test Site Vicinity, Clark, Lincoln, and Nye Counties, Nevada and Inyo County, California.

Description: Ground water moving through permeable Paleozoic carbonate rocks represents the most likely pathway for migration of radioactive contaminants from nuclear weapons testing at the Nevada Test Site, Nye County, Nevada. The strontium isotopic composition (87Sr/86Sr) of ground water offers a useful means of testing hydrochemical models of regional flow involving advection and reaction. However, reaction models require knowledge of 87Sr/86Sr data for carbonate rock in the Nevada Test Site vicinity, wh… more

R- AND P- REACTOR VESSEL IN-SITU DECOMISSIONING VISUALIZATION

Description: The R- & P- Reactor facilities were constructed in the early 1950's in response to Cold War efforts. The mission of the facilities was to produce materials for use in the nation's nuclear weapons stockpile. R-Reactor was removed from service in 1964 when President Johnson announced a slowdown of he nuclear arms race. PReactor continued operation until 1988 until the facility was taken off-line to modernize the facility with new safeguards. Efforts to restart the reactor ended in 1990 at the end… more

SECURITY MODELING FOR MARITIME PORT DEFENSE RESOURCE ALLOCATION

Description: Redeployment of existing law enforcement resources and optimal use of geographic terrain are examined for countering the threat of a maritime based small-vessel radiological or nuclear attack. The evaluation was based on modeling conducted by the Savannah River National Laboratory that involved the development of options for defensive resource allocation that can reduce the risk of a maritime based radiological or nuclear threat. A diverse range of potential attack scenarios has been assessed. … more

U.S. Nuclear Cooperation with India: Issues for Congress

Description: India, which has not signed the Nuclear Nonproliferation Treaty and does not have International Atomic Energy Agency safeguards on all of its nuclear material, exploded a “peaceful” nuclear device in 1974, convincing the world of the need for greater restrictions on nuclear trade. The United States created the Nuclear Suppliers Group (NSG) as a direct response to India's test, halted nuclear exports to India a few years later, and worked to convince other states to do the same. India tested nuc… more

The New START Treaty: Central Limits and Key Provisions

Description: This report provides an overview of the new strategic arms reduction treaty (New START), including a comparison to the original START Treaty, the belief of the Obama Administration and outside analysts that New START will enhance U.S. national security, and the criticisms of those who say that New START (and, indeed, the entire issue of U.S.-Russian arms control) is a distraction from more important items on the nonproliferation agenda.

FMDP reactor alternative summary report. Volume 1 - existing LWR alternative

Description: Significant quantities of weapons-usable fissile materials [primarily plutonium and highly enriched uranium (HEU)] are becoming surplus to national defense needs in both the United States and Russia. These stocks of fissile materials pose significant dangers to national and international security.
