ISR Workspace: Increased Contract Volume

Show Details Jun 26, 2026 Following the implementation of revisions to the ISR eligibility logic within the Subcontracting Plan Reporting system on June 9, 2026, contractors might observe an increased volume of contracts and subcontracts in their Eligible Workspace. The inclusion of these records does not automatically necessitate an ISR submission. Contractors must evaluate the specific subcontracting plans associated with each contract and subcontract to determine their reporting obligations.

Subcontracting Plan Reporting system issues resolved

Show Details Jun 10, 2026 GSA deployed updates to SAM.gov to resolve known issues with the Subcontracting Plan Reporting system. Contractor users should review their Workspaces to ensure they can successfully create and submit their Individual Subcontracting Reports (ISR). Mid-year ISRs are due July 14, 2026. Visit sam.gov/esrs for more information.

An accelerator-driven, sub-critical molten-salt nuclear system that centrally produces large quantities of tritium for fusion energy. By pairing accelerator-driven subcritical operation with molten-salt chemistry, the system offers a controllable, safety-forward pathway to produce fusion fuel, recover useful energy and convert legacy nuclear liabilities into strategic energy assets.

Overview:

The Accelerator-Driven Sub-Critical Molten-Salt Assembly (ADS+MSA) is a centralized nuclear facility that uses a high-power particle accelerator coupled to a liquid molten-salt system to reliably produce kilogram-scale quantities of tritium. Because the system is sub-critical, nuclear reactions only occur when driven by the accelerator, providing inherent safety and operational control. By combining proven accelerator technology with modern molten-salt chemistry, the ADS+MSA removes a major bottleneck to commercial fusion energy, recovers useful energy, and strengthens U.S. energy security and national security missions under existing Department of Energy safety frameworks rather than commercial reactor licensing.

Key Advantages: Enables large-scale commercial fusion energy by providing a reliable, centralized source of tritium, eliminating the need for fusion plants to breed their own fuel and significantly reducing cost, complexity, and deployment risk. Operates in an inherently safe, sub-critical configuration in which nuclear reactions stop when the accelerator is turned off, avoiding runaway scenarios and allowing operation under DOE…

Topic areas: General and Cross-cutting R&D, Energy and Environment.
