Lower corner of front cover has a small crease. The Dual-Axis Radiographic Hydrodynamic Test (DARHT) facility is a vital and important part of the Nation's nuclear security enterprise. The Department of Energy/National Nuclear Security Administration (DOE/ NNSA) Stockpile Stewardship Management Plan (SSMP) identifies DARHT as a weapons mission critical facility along with the need to modernize DARHT to support weapons modernization efforts. With more than two decades of operations, DARHT has a storied history. Conceived in the 1970s, constructed in the 1990s, and operational since 2000, DARHT has advanced from open-air hydrodynamic experiments to foam-confined hydros, to vessel-confined hydros, and in 2022, the 75th hydro was successfully completed. Radiography has advanced from a single-axis, single-pulse system to a dual-axis, multi-pulse capability to variable fields of view on both accelerators. What do the next two decades at DARHT look like? Evolving threats, an expanding mission, and technology changes necessitate adaptation. The 2018 Nuclear Posture Review states that the nuclear weapons infrastructure has aged no margin for further delay in recapitalizing the physical infrastructure. The aging facility, accelerators, vessels, and detector systems require improvements to ensure DARHT remains the Nation's hydrodynamic data foundation for stockpile certification, safety, surety, and global security threats. The Lab's Dual Axis Radiographic Hydrodynamic Test (DARHT) facility is used to take high-speed images of mock nuclear devices and other materials as they implode. Howard Bender, a group leader in the Lab's Integrated Weapons Experiments Division, says the facility's two massive electron accelerators are used to produce critical dataâ "in the form of radiographsâ "that help ensure the safety, security, and effectiveness of the United States' nuclear deterrent. "When it comes to nuclear weapons, scientists have constant questions regarding the safety, materials, aging, new designs, and other aspects of the various systems," Bender says. "DARHT helps us answer these questions." Currently, scientists are using DARHT to carry out hydrodynamic experiments on plutonium surrogatesâ "materials that behave similarly to plutonium but do not create a nuclear reaction. These tests provide essential experimental data to constrain computational codes for nuclear weapons, which is a critical component of maintaining the nuclear weapons stockpile. These tests also provide useful data for experiments at the Nevada National Security Site, which is the only place where subcritical experiments using actual plutonium can take place. This document details the strategy proposed to meet the National Nuclear Security Administration (NNSA) required for the The Dual-Axis Radiographic Hydrodynamic Test (DARHT) Facility Sustainment and Modernization projects identified in multiple NNSA Stockpile Stewardship and Management Plan (SSMP) reports to Congress (NNSA, 2022, 2021, 2022, 2023). DARHT has become indispensable for the certification of primaries of U.S. nuclear weapons since the current U.S> moratorium halted underground nuclear testing more than 30 years ago. However, aging facilities, evolving technology, and other issues are limiting or threatening the capability of DARHT to meet NNSA's expanding mission needs now and into the future. THIS DARHT Capability eXpansion (DCX) strategy was developed to address NNSA needs by extending DARHT's reliability and resilience, increasing the quality and quantity of DARHT data, and enabling hydrodynamic measurements in complex environments. The strategy can be implemented through integration of line-item projects, acquisition of major items of equipment,m and other actions coordinated with the execution of the SSMP. This strategy document is intended for U.S> Government officials, particularly authorizers, appropriators, and program leaders. It may also be furnished to DARHT users, customers, collaborators, stakeholders, and visitors as needed.
