¹ In­stall­a­tions in which the fol­low­ing nuc­le­ar ma­ter­i­als are ob­tained, pro­duced, used, pro­cessed or stored are not clas­si­fied as nuc­le­ar in­stall­a­tions:

a.

sub­stances that con­tain a total of not more than 1,000 kg of nat­ur­al urani­um, de­pleted urani­um or thori­um;

b.

source ma­ter­i­als for which evid­ence can be provided that a sus­tain­able chain re­ac­tion is not pos­sible due to the chemico-phys­ic­al con­di­tion of the ma­ter­i­als and the ex­ist­ing op­er­at­ing con­di­tions;

c.

spe­cial fis­sile ma­ter­i­als that con­tain a total max­im­um of 150 grams of plutoni­um 239, urani­um 233 or urani­um 235.
