Description
The compact, high field fusion experiment Ignitor aims at the demonstration, for the first time, of ignition in magnetically confined D-T plasmas, together withthe exploration of the physics of the ignition process, and of heating and control of plasmas under controlled burning conditions. The machine parameters have been established on the basis of existing knowledge of the confinement properties of high density plasmas and technological feasibility.
The collaboration between Italy and Russia is centered on the construction of Ignitor in Italy and its installation and operation within the Troitskii Institute of Innovative and Thermonuclear Research (TRINITI) site (near Troitsk, Greater Moscow, Russia).The site, hosting since decades nuclear installations, is well characterised, both from the meteorological and population aspects: large amounts of data were collected over the years. Moreover, many assessments made for the SFT (Strong Field Tokamak) are applicable to Ignitor. A Tritium system to be operated up to 10g/day is already available, much more than the Ignitor requirements. Being TRINITI a fully characterized nuclear site, we can conclude that is fully apt to host Ignitor, according both to international and to Russia’s regulations.
A Preliminary Safety Report (PSR) in under preparation for the siting of Ignitor at TRINITI. Deterministic evaluations (radioactive inventory and dose population codes) have been performed. The preliminary radiological impact analysis for the normal operation and the main accidental sequences of Ignitor, for the case of its localization at TRINITI are presented, along the lines of the assessment done for the Italian site of Caorso.
The Ignitor machine, both during routine functioning and accidental sequences, presents a negligible radiological impact. No need of people evacuation or any emergency countermeasure is necessary even in presence of the worst accident.
