When a nuclear activity has not begun within three years of the issue of the receipt for the declaration or notification of the registration or authorisation, the declaration, registration or authorisation lapses.
In the event of definitive withdrawal of the registration or authorisation issued in application of the third paragraph of Article L. 1333-31, the Nuclear Safety Authority shall prescribe to the person responsible for the nuclear activity the conditions under which current or future radioactive sources and radioactive waste are to be disposed of at his/her expense.
