Article 25 



1. Each of the States Parties to this Treaty undertakes to refrain from the emplacement or 

 installation on or in the seabed or subsoil of ocean space of any objects containing nuclear weapons or 

 any kinds of weapons of mass destruction, or the stationing of such weapons on or in the seabed or 

 subsoil of ocean space in any other manner.

Article 26 



All stations, installations, equipment, and sea vehicles, machines, and capsules, whether manned or 

 unmanned, on the seabed or in the subsoil of ocean space shall be open to representatives of other States 

 Parties to the Treaty on a basis of reciprocity, but only with the consent of the State concerned. Such 

 representatives shall give reasonable advance notice of a projected visit in order that appropriate 

 consultations may be held and that maximum precautions may be taken to assure safety and to avoid 

 interference with normal operations in the facility to be visited. All such facilities shall be open at any 

 time to the Sea Guard of the United Nations referred to in Part VII of this Treaty, subject to the con trol 

 of the Security Council as set forth in such Part. 



Part V-Regulations on the Disposal of Radioactive Waste Material in Ocean Space 



Article 27 



The disposal of radioactive waste material in ocean space shall be subject to safety regulations to be 

 prescribed by the International Atomic Energy Agency, in consultation with the licensing authority 

 referred to in Article 12 of this Treaty. 



Article 28 



In the event of the conclusion of any other international agreements concerning the use of nuclear 

 energy, including the disposal of radioactive waste material, to which all of the States Parties to the 

 Treaty are parties, the rules established under such agreements shall apply in ocean space. 



Part VI-Limits of Continental Shelf 



Article 29 



In order to assure freedom of the exploration and exploitation of ocean space and its resources as 

 provided in this Treaty, there is a clear necessity that fixed limits must be set for defining the outer 

 boundaries of the continental shelf of coastal States. For the purpose of the provisions of this Treaty, 

 the term "continental shelf" is used as referring (a) to the seabed and subsoil of the submarine areas 

 adjacent to the coast but outside the area of the territorial sea to a depth of 600 metres, and(b) to the 

 seabed and subsoil of similar submarine areas adjacent to the coasts of islands. Recognizing the 

 desirability of achieving agreement on unsettled questions relating to defining the boundaries of the 

 continental shelf. States Parties to the Treaty undertake to accept any agreements which may be reached 

 in the event a conference is convened to consider such questions as provided for in Article 13 of the 

 Convention on the Continental Shelf adopted at Geneva on 29 April 1958; and any agreement so 

 reached shall become effective for purposes of this Treaty when approved by the conference.
