At least 4-7 kgs of HEU enriched to 90%.
Unsafeguarded.
One 18 VWt pond-type research reactor (VVR-M), fueled by 4-7 kgs of
90% HEU, is operating at the St. Petersburg institute. A 100 MWt tank-vessel
type research reactor (PIK) is under construction. The larger reactor, when
operational, will use about 30 kgs of 90% HEU, some of which may already be
stored at the site.
The site was selected by Gosatomnadzor in 1995 as one
of several to receive Material Protection Control & Accountability upgrades.
