S.F.R. Mark I

The S.F.R. Mark I, full name Synthetic Fusion Reactor Mark I, was an inertial confinement superstructure integrated into Meridian Depthworks bedrock. It provided approximately 80 percent of United Columbus power at peak before being decommissioned after the 1987 Thermal Runaway.

Design

Hex Triad array

Two triangular sets of three C-2500 power lasers at 120 degree offsets, forming a pressure cage around the focal point. Designed to eliminate hydrodynamic instability during compression. Source: SFR_TECHNICAL_SPECIFICATIONS.

Compression cycle

Ablator vaporizes outward, driving sheer force inward above 350 km/s to approximately 100 times lead density. Nanosecond symmetry is required. Failure produces soap bar effect, misfire, and wall strike. Target tolerance is 2 microns. Charge hum reaches 110 decibels.

Chamber

20 meter sphere with sacrificial First Wall, liquid lithium blanket at 5,000 L/min, near perfect vacuum below 1e-6 Torr, magnetic dampeners at 100 percent. Blanket heat drives steam turbines.

Fuel

Heavy nucleus lattice compound, exact formula redacted. Cell contains ablator shell, isotope core, and beryllium lead neutron multiplier.

Grade	Role	Cycle	Risk
9 Standard	85 percent of ops, balanced	24 hours	Predictable below 35 keV
8 Reactive	Peak load, overclock	4 to 6 hours	Symmetry margin reduced 50 percent, 140 percent output
7 Efficiency	Idle, maintenance	Up to 168 hours	Cannot reach heavy output

Operating limits

• Plasma 15 to 25 keV normal, above 35 keV fission risk, 41.2 keV Shatter Point with golden glow feedback
• STI 1.0 to 4.9 normal, 5.0 critical, 7.0 Hell's Throat opens, 10.0 thermal runaway
• Integrity 80 to 100 percent green, 50 to 79 yellow, below 30 red with mandatory scram

C-2500 and Stress

Segmented cylinder, CO2 Xenon mix, orange induction rings, nitrogen coolant cage. Single discharge exceeds 1965 field output by orders of magnitude. Exact yield is Level 3 restricted.

• 1st overload: breaker trip, 60 second reboot
• 2nd overload: permanent efficiency loss, faster Stress gain
• 3rd overload: total burnout

Coolant flood risks thermal stall. Purge requires 90 second recharge. Five to six compensation adds 20 percent Stress each. More than two offline causes instabilities. F.A.M.S. autocontrol protects hardware over keV stability. Crew split 1 to 3 and 4 to 6 is common. Source: PSI-C2500-SPEC-68.

Emergency procedures

1. SCRAM. Grid decouple, 10,000V master switch bypassing software, lead boron baffle injection. Source: PSI-SOP-B-REAC, PSI-EMERGENCY-B-87.
2. Desync Vent Protocol. Manual server room and Mainframe overrides plus F.A.M.S. brute force, forced desync requiring hand reboot of faulted lasers, then destructive structural vent before network loss.
3. Receptacle ejection. Four cells to borated pit 50 meters below within 1 to 3 second sync. Failure risks magnetic shear. Unsanctioned interior manual pull is documented with F.A.M.S. phrase trust me go.

History

1987 Thermal Runaway from failed primary scram reached STI 10.0 with golden glow. Saved only by synchronized ejection. Proof that scram failure can escalate fully and that ejection timing is decisive. The incident led directly to decommissioning: Mark I never returned to service, and the facility entered a long closure ending in 2018.

Later analysis by F.A.M.S. in 2018 and 2019 disputed the mechanical failure verdict. After fourteen months parsing 87 logs he concluded the true cause was thread starvation during peak telemetry spikes compounded by human response delay, motivating his self-directed sub node architecture. See FAMS.

Successor

The Mark II Synthetic Fusion Reactor replaced Mark I and is the current core, operating by 2019 on F.A.M.S.'s multi node architecture at 18 percent below design spec thermal load.
