With the Sochi Olympics set to start on February 6th there has been an escalating concern about security threats to the Games. There are hunts for female suicide bombers (“black widows”), video threats from militant groups, etc., all of which have triggered a massive Russian security response, including statements by President Putin insuring the safety […]
By Hans M. Kristensen The former U.S. Air Force Chief of Staff, General Norton Schwartz, confirmed last week that the B61-12 nuclear bomb planned by the Obama administration will have improved military capabilities to attack targets with greater accuracy and less radioactive fallout. The confirmation comes two and a half years after an FAS publication […]
While the theft of a truck carrying radioactive cobalt made international headlines, this was unfortunately not the first time thieves or scavengers have exposed themselves or others to lethal radiation. Probably the most infamous case was on September 13, 1987 in Goiania, Brazil. Scavengers broke into an abandoned medical clinic and stole a disused teletherapy […]
As hoped, the P5+1 and Iran settled on a “first step” agreement to resolve concerns about Iran’s potential to develop nuclear weapons and its interest in doing so. We cannot predict how far this process will go or what the next step to establish a comprehensive, enduring agreement that puts the nuclear issue squarely in the […]
By Hans M. Kristensen A new Congressional Budget Office (CBO) report – Options For Reducing the Deficit: 2014-2023 – proposes reducing the Navy’s fleet of Ohio-class ballistic missile submarines from the 14 boats today to 8 in 2020. That would save $11 billion in 2015-2023, and another $30 billion during the 2030s from buying four […]
A congressional impasse on what to do with U.S. reactors’ spent nuclear fuel could last to 2017 or beyond unless a compromise can be found between the House and Senate. The House has voted to support finishing review of the site license application for the Yucca Mountain repository, but the Senate has not. Facing opposition […]
A look at the Global Threat Reduction Initiative (GTRI) and its work to reduce the amount of vulnerable nuclear and radiological material located at civilian sites worldwide and improve protection of these materials.
Formed over 6 billion years ago, uranium, a dense, silvery-white metal, was created “during the fiery lifetimes and explosive deaths in stars in the heavens around us,” stated Nobel Laureate Arno Penzias.1 With a radioactive half-life of about 4.5 billion years, uranium-238 is the most dominant of several unstable uranium isotopes in nature and has […]
The election of Hassan Rouhani as the president of Iran has breathed new life into the negotiations over Iran’s nuclear program. In recent months, a flurry of meetings has raised hopes that this program can remain peaceful and that war with Iran can be averted. But barriers still block progress. Among the major sticking points […]
Starting from literally table-top science in 1939, the development of a full-fledged nuclear weapons production system in the United States by late summer 1945 is properly regarded as a near-miraculous achievement. It’s no surprise that the Manhattan Project has long been hailed as one of the great success stories of modern science and technology. But […]
By Hans M. Kristensen China continues to upgrade bases for mobile nuclear medium-range ballistic missiles. The image above shows one of several new launch pads for DF-21 missile launchers constructed at a base near Jianshui in southern China. A new satellite image* on Apple Maps shows the latest part of a two-decade long slow replacement […]
By Hans M. Kristensen With every official statement about the B61 nuclear bomb life-extension program, the capabilities of the new version (B61-12) appear to be increasing. Previously, officials from the DOD, STRATCOM, and NNSA said the program is a consolidation of the B61-3, B61-4, B61-7, and B61-10 gravity bombs that would provide no additional military […]
