which it can meet them.

If the Agency cannot meet in their entirety all the orders received, it shall, subject to  the provisions of Articles 68 and 69, share out the supplies proportionately among  the orders relating to each offer.

Agency rules, which shall require approval by the Commission, shall determine the  manner in which demand is to be balanced against supply.

Article 61

The Agency shall meet all orders unless prevented from so doing by legal or  material obstacles.

When concluding a contract, the Agency may, while complying with the provisions  of Article 52, require users to make appropriate advance payments either as security  or to assist in meeting the Agency's own long term commitments to producers where  these are essential to carrying out the order.

Article 62

1. The Agency shall exercise its right of option on special fissile materials produced  in the territories of Member States in order:

a. to meet demand from users within the Community in accordance with Article  60; or
b. to store such materials itself; or
c. to export such materials with the authorization of the Commission which shall  comply with the second subparagraph of Article 59 ( b ).

2. Nevertheless, while continuing to be subject to the provisions of Chapter 7, such  materials and any fertile wastes shall be left in the possession of the producer, so  that he may:

a.store them with the authorization of the Agency; or  
b. use them within the limits of his own requirements; or  
c. make them available to undertakings in the Community, within the limits of their  requirements, where for carrying out a programme duly communicated to the  Commission, these undertakings have with the producer a direct connection  which has neither the aim nor the effect of limiting production, technical  development or investment or of improperly creating inequalities between users  in the Community.

3. The provisions of Article 89 ( 1 ) ( a ) shall apply to special fissile materials which  are produced in the territories of Member States and on which the Agency has not  exercised its right of option.
