Russia withdraws from 25-year-old weapons-grade plutonium agreement
Russia’s lower house of Parliament, the State Duma, approved a measure to withdraw from a 25-year-old agreement with the United States to cut back on the leftover plutonium from Cold War–era nuclear weapons.

Fusion facility safety and reliability/availability analyses require accurate component failure rate information to provide meaningful results. While fission reactor operating experience data may be adequate for some types of components, there are some data needs that are fusion-specific, such as tritium fueling and handling system information. This paper summarizes the results of a failure data analysis task on several components at Los Alamos National Laboratory's Tritium Systems Test Assembly (TSTA). We took the failure reports and component operating information from the TSTA Failure/Maintenance Data Base. Calculated failure rates are on the same order of magnitude as screening fusion failure rate data, although a few failure rates were slightly higher. These new data should be of interest to fusion safety analysts and tritium systems designers.
