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.

Initiative None

The Heat Pipe Reactor Fire Mitigation and Suppression System from Los Alamos National Laboratory, transforms the heat pipes inside an alkali metal-cooled nuclear reactor from passive thermal conduits into active, sensor-driven fire defense components, giving designers of advanced small and microreactors a layered, automated safeguard against one of the most challenging hazards in their systems. By combining an inert gas buffer, a phase change material jacket, automated suppressant injection at multiple points and optional neutron-absorber dispersion into the reactor core, the system delivers redundant protection that responds within milliseconds of detecting fire-like conditions. This system enables advanced reactor developers to meet stringent safety expectations for remote, unattended and space-constrained deployments without redesigning the core architecture around bulky external suppression equipment.

How it Works

During normal operation, each heat pipe carries thermal energy away from the reactor core through the evaporation and condensation of an alkali metal working fluid, while valves connecting the heat pipe to external suppressant chambers remain closed. Temperature and pressure sensors continuously monitor the heat pipe reactor core and the valves near each heat pipe end, feeding data to a controller that compares readings against predefined thresholds. When a reading crosses the first threshold, the controller opens a valve and forces a fire suppressant material, typically a boron compound, into the interior…
