It is also the site where, from 1963 to 1990, about 39 underground nuclear tests took place in a vast array of tunnels and shafts under Mount Lazarev and other massifs. After 2000, Russia started to reactivate the test site by enlarging old tunnels and starting construction work. Each summer since then various subcritical hydronuclear experiments have taken place. In 2004, Rosatom reportedly performed a series of subcritical hydronuclear experiments with up to Template:Convert of weapon-grade plutonium each.<ref name="nti">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
