2. The facilities and activities referred to in paragraph 1 are the following:

(a) any nuclear reactor wherever located;

(b) any nuclear fuel cycle facility;

(c) any radioactive waste management facility;

(d) the transport and storage of nuclear fuels or radioactive wastes;

Assistance to States Parties

The Agency shall, in accordance with its Statute and upon a request of a State Party which does not have nuclear activities itself and borders on a State having an active nuclear programme but not Party, conduct investigations into the feasibility and establishment of an appropriate radiation monitoring system in order to facilitate the achievement of the objectives of this Convention.

Article 9

Bilateral and multilateral arrangements

In furtherance of their mutual interests, States Parties may consider, where deemed appropriate, the conclusion of bilateral or multilateral arrangements relating to the subject matter of this Convention.

Article 10
