The ITER Baseline Scenario refers to a defined set of operational parameters and performance goals established for the International Thermonuclear Experimental Reactor (ITER) project. This scenario serves as a reference framework for achieving sustainable nuclear fusion reactions, focusing on plasma performance, energy output, and operational efficiency. The baseline scenario is crucial for guiding experimental designs and assessing the potential of fusion as a viable energy source.
congrats on reading the definition of ITER Baseline Scenario. now let's actually learn it.
The ITER Baseline Scenario aims for a plasma temperature of approximately 150 million degrees Celsius, which is necessary for achieving the conditions for fusion.
One of the key performance goals is to achieve a fusion gain factor (Q) greater than 10, meaning that the reactor produces ten times more energy than it consumes.
The baseline scenario outlines specific operational timescales for plasma stability, targeting sustained plasma operation for up to 400 seconds during experiments.
Safety protocols and environmental considerations are integral to the ITER Baseline Scenario, ensuring that the fusion process can be conducted without negative impacts on the environment or public safety.
The parameters defined in the ITER Baseline Scenario will be continually refined based on experimental results and advancements in fusion research over time.
