The IGNIR collaboration between Italy and Russia is centred on the construction of the core of the Ignitor machine in Italy and its installation and operation within the TRINITI site (Troitsk, Russia). A Preliminary Safety Report is under preparation for the siting of the Ignitor experiment in Troitsk. A specific site has been selected, with characteristics determined from informations regarding TRINITI. This site has many positive characteristics, such as the presence of electrical facilities because of nearby distribution nodes, and the full availability of the required room for the arrangement of all Ignitor buildings. The results of the analyses, both regarding doses to population and personnel, and other environmental impacts, show that the TRINITI site in Troitsk is a consistent choice for Ignitor localisation, according to the safety and the environmental impact point of view.
