  2. Electron paramagnetic resonance - Wikipedia

    en.wikipedia.org/wiki/Electron_paramagnetic...

    Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials that have unpaired electrons.The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei.

  3. Nuclear reactor safety system - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reactor_safety_system

    The Automatic Depressurization System (ADS) consists of a series of valves which open to vent steam several feet under the surface of a large pool of liquid water (known as the wetwell or torus) in pressure suppression type containments (typically used in boiling water reactor designs), or directly into the primary containment structure in ...

  4. Electronically controlled unit injector - Wikipedia

    en.wikipedia.org/wiki/Electronically_controlled...

    An electronically controlled unit injector (EUI) sometimes referred to as a mechanical electronic unit injector (MEUI) is a unit injector (UI) with electronic control. It performs the same function as a conventional unit injector in an internal combustion engine , such as in an on-road or off-road vehicle or a diesel-electric locomotive .

  5. EPR (nuclear reactor) - Wikipedia

    en.wikipedia.org/wiki/EPR_(nuclear_reactor)

    The reactor can use 5% enriched uranium oxide fuel, reprocessed uranium fuel or 100% mixed uranium plutonium oxide fuel, clad in Areva's M5 variant of zirconium alloy. [11] [12] The EPR is the evolutionary descendant of the Framatome N4 and Siemens Power Generation Division "Konvoi " reactors. [13] [14] Siemens ceased its nuclear activities in ...

  6. Jetronic - Wikipedia

    en.wikipedia.org/wiki/Jetronic

    Mechanical fuel injection, 'K' stands for German: "Kontinuierlich", meaning continuous.Commonly called 'Continuous Injection System (CIS) in the USA. K-Jetronic is different from pulsed injection systems in that the fuel flows continuously from all injectors, while the fuel pump pressurises the fuel up to approximately 5 bar (73.5 psi).

  7. Rochester Ramjet - Wikipedia

    en.wikipedia.org/wiki/Rochester_Ramjet

    The Ramjet is a continuous-flow port-injection system. Unlike later fuel injection systems that used electronics, this one is based on purely mechanical principles. The two main sub-assemblies of the system are the air meter and the fuel meter. The air meter measures airflow into the engine and manages thermostatic warmup enrichment, fuel ...

    en.wikipedia.org/wiki/Olkiluoto_Nuclear_Power_Plant

    The Onkalo spent nuclear fuel repository is a deep geological repository for the final disposal of spent nuclear fuel, the first such repository in the world. It is currently under construction at the Olkiluoto plant by the company Posiva , owned by the nuclear power plant operators Fortum and TVO .

  9. Stuart Hilborn - Wikipedia

    en.wikipedia.org/wiki/Stuart_Hilborn

    Hilborn eventually started a company to sell his injection systems to the public, which became popular with the hot rodders of the 1950s and 1960s. A classic mechanical Hilborn injection system is recognizable by its distinctive flared velocity stack intake pipes, rising straight up from each cylinder, flared at the open top, and usually ...
