The GE VMIVME-7807 (full model VMIVME-017807-413000-350-0001007807-413000-D) is a radiation-hardened, conduction-cooled single-board computer from GE’s VMIC series, engineered for ultra-reliable operation in nuclear power, aerospace, and defense applications where ionizing radiation and extreme environments compromise standard electronics. Leveraging a radiation-tolerant PowerPC™ architecture, this 6U VMEbus module delivers deterministic processing while withstanding total ionizing doses (TID) up to 100 krad(Si) and single-event latch-up (SEL) immunity >120 MeV·cm²/mg. The GE VMIVME-7807 integrates triple-redundant voting logic, error-correcting code (ECC) memory, and MIL-grade construction to ensure uninterrupted operation in nuclear reactor containment vessels, satellite systems, and particle accelerator controls.
Designed for VME64x backplanes, this SBC features configurable radiation hardening levels (RH32/RH1100) and operates across -55°C to +125°C ambient temperatures without performance degradation. Its hermetic sealing and lead-shielded components prevent neutron flux-induced bit flips, making the GE VMIVME-7807 indispensable for safety-critical systems requiring SIL 4 certification. For nuclear plant modernization or space missions, this module sets the benchmark for radiation-hardened computing.

Main Features and Advantages
Nuclear-grade resilience: Triple modular redundancy (TMR) and latchup self-detection circuits automatically recover from single-event upsets (SEUs). Hermetic gold-sealed packaging prevents helium infiltration in space applications.
Deterministic fault containment: Hardware-enforced memory partitioning isolates critical safety functions (e.g., reactor trip logic). Built-in scrubbers correct single-bit memory errors every 10 μs.
Extreme environment operation: Conduction-cooling sustains 125°C ambient in reactor drywells. Neutron-absorbing boron-coated components prevent thermal runaway during flux transients.
Application Field
The GE VMIVME-7807 dominates:
Nuclear Power: Executes reactor protection system (RPS) algorithms in GE Mark I containment
Space Systems: Processes flight control in high-radiation orbits (e.g., polar/GEO satellites)
Particle Physics: Controls beamline instrumentation at CERN LHC experiments
Military Nuclear: Manages propulsion controls in nuclear submarines
Fusion Research: Monitors plasma confinement in tokamak diagnostics
