PWR Load Following: Judge Rod-Turbine Coordination Interlocks by Return Margin
Control-level interlocks for PWR load following: accept turbine load requests based on rod insertion limit, delta-I band and post-xenon return reactivity margin.
Reformed vs Green Hydrogen — Supply Paths for Fuel Cell Power Plants Split on Continuity
Gray, blue and green hydrogen paths compared from the standpoint of continuous fuel cell operation, with the electrolyzer size and storage buffer needed to run 1 MW on solar-only green hydrogen.
Spent Fuel Wet vs Dry Storage: Power Dependence Decides
Pool storage and dry cask storage compared by decay heat and power dependence, with criteria for when the pool should be emptied.
ESS DC Breaker and Fuse Coordination: The Rack Protective Device Must Clear the Sum of the Other Racks — Reverse Fault Current and Contactor Open-Inhibit
In a parallel-rack ESS, each rack’s protective device must clear the summed reverse current from the other racks. Fault current range, non-polarized interruption, contactor logic.
Fluence–EVE 206 GWh Cell Deal and US Plant Delays — Thermal Management, Not Cells, Sets BESS Delivery
Fluence’s 206 GWh deal with EVE came the week it cut outlook by USD 600 million. The bottleneck was thermal-unit welding, not cells; two supply tracks compared.
45 GW of Data Centre UPS: The Circuits and Interlocks Behind a 0 ms Transfer Time
The criterion for choosing a UPS is transfer time (ms), not kVA. IEC 62040-3 classes, backup time sizing code, an I/O map and an interlock checklist.
Korea’s Solar LCOE: When Will the Gap with Global Levels Narrow?
Why Korea’s solar LCOE is about twice international levels, and the conditions under which the gap narrows.
Immersion-Cooled ESS: How Thermal Runaway Interlock Design Differs from Air Cooling
In immersion-cooled ESS, coolant circulation and level interlocks must rank above cell temperature interlocks. Safety interlock order and I/O checklist, based on G2Power’s AI immersion-cooled ESS.
Doosan Fuel Cell Hit by CHPS Cuts: When Should Power Producers Favour the Switch to SOFC?
With CHPS auction volume cut by 30.2%, Doosan Fuel Cell’s PAFC business is at a crossroads and a shift to SOFC is under way. The conditions power producers need to weigh.
RPS 2-out-of-4 Coincidence Logic: Bypass or Trip the Channel Under Maintenance?
Bypass (2/3) or tripped state (1/3) for an RPS channel under maintenance, judged by spurious-trip margin and hardwired mutual exclusion.
