The Transient Reactor Test (TREAT) facility at the Idaho National Laboratory currently utilizes a legacy Zircaloy-3 cladding, which is no longer commercially available. TREAT air cooled and routinely operates temperatures well above that of traditional reactor designs. This study investigates oxidation behavior pure zirconium its alloys (Zircaloy-3, Zircaloy-4, Zr-1Nb, Zr-2.5Nb) in Ar+20%O2 N2+20%O2 atmospheres ranging from 400–800°C to determine alloy should be implemented as TREAT's...
Multiple spectroscopy diagnostics have been fielded on the FuZE-Q sheared-flow-stabilized (SFS) Z-pinch to measure plasma impurities, flow velocity, temperature, and density. The currently cover wavelengths from extreme ultraviolet (EUV) in 5–40 nm (30–250 eV) range, ion Doppler (IDS) 225–233 compact broadband (UV/VIS) 220–1050 range. Spectral databases collisional-radiative (CR) modeling used identify impurities estimate parameters. Many emission lines deuterium (D), carbon (C), oxygen (O)...
Abstract The Transient Reactor Test (TREAT) facility is a research reactor designed to simulate rapid transients test new fuel designs. TREAT's cladding exposed unique conditions compared normal water reactors. These include: exposure air at high temperatures (≥600 °C), heating (≈700 °C/s), and geometry that includes chamfers welds. This work investigates the effects of chamfering welding on oxidation behavior zirconium alloys (Zircaloy-3, Zircaloy-4, Zr–1Nb). Tube specimens were examined...
Among the activities of European Metrology Research Programme (EMRP) project HiTeMS one work package is devoted to development and testing industrial solutions for long-standing temperature measurement problems at highest temperatures. LNE-Cnam, NPL, TUBITAK-UME have worked on design high fixed points (HTFP) suitable in-situ monitoring be implemented in facilities CEA (Commissariat à l’énergie atomique et aux énergies alternatives). Several point cells were constructed these three national...
Monitoring processes taking place inside furnaces often involves measurement of temperature using a radiation thermometer looking through window unknown, and possibly varying, transmission. This can introduce significant errors. In this paper we consider two approaches to dealing with problem based on particular case vacuum induction furnace. The use ratio is compared measurements known reference point embedded in the process monochromatic generate correction curve. It found that an included...
Severe accident experiments are conducted on the PLINIUS platform in Cadarache, using prototypic corium. During these experiments, it is essential to measure temperature know thermo-physical state of corium static and dynamic conditions or monitor concrete ablation phenomenology. Temperature can reach about 2000 3000 K. Such aggressive restrict type diagnostics that be employed do high measurements during experiments. We employ both non-intrusive (pyrometers) intrusive (K-type C-type...
Zap Energy Inc. is rapidly developing the technology to produce fusion-relevant z-pinch plasma discharges stabilized via sheared flow. The Z-pinch configuration offers promise of a compact fusion device owing its simple geometry, unity beta, and absence external magnetic field coils. In addition robust experimental program pushing performance towards breakeven conditions [1] , has parallel programs power handling systems suitable for future plants including: high-average-power repetitive...
