Stockpile Stewardship
program to maintain and certify the nuclear weapons stockpile without full-scale testing, using simulations and HEDP experiments.
01 Definition
The U.S. program to maintain and certify the nuclear weapons stockpile without full-scale testing, using simulations and HEDP experiments. Created in 1993-1994 via PDD/NSC 15 and the NDAA of 1994. The SSP provides an alternative explanation for the fusion-weapons dual-use at NNSA laboratories: NIF, Z Machine, and Atlas are primarily weapons stewardship facilities with fusion energy as a secondary benefit. ICF is explicitly designated a 'major component' of the SSP. The SSP is transparent (PDD/NSC 15, Federal Register) and its purpose is maintaining existing weapons — not developing new ones.
02 Detailed_Analysis
Overview
The Stockpile Stewardship Program (SSP) was created in 1993-1994 as a condition of the Comprehensive Test Ban Treaty (CTBT). Its purpose is to maintain the safety and reliability of the U.S. nuclear weapons stockpile without underground nuclear testing.
Key Documents
- PDD/NSC 15 (1993): Explicitly states that 'the ICF program is considered by DOE to be a major component of several of the PDD program elements.'
- National Defense Authorization Act of 1994: Congressional authorization.
- Federal Register (October 1995): DOE SSP EIS.
Major Facilities
- NIF (LLNL): Primary mission is Stockpile Stewardship. Energy is secondary.
- Z Machine (Sandia): 'Crucial to Sandia's mission to assure the reliability and safety of our nuclear stockpile.'
- Atlas (LANL → Nevada Test Site): SSP experiments, relocated to Nevada Test Site.
Alternative Explanation
The SSP provides an alternative explanation for the fusion-weapons dual-use: NNSA fusion facilities are primarily weapons facilities with fusion energy as a secondary benefit. Both the thesis (covert plasma weapons may exist) and the SSP alternative (fusion is secondary benefit of weapons stewardship) are consistent with the evidence.
