It is superstition to ban them, but making sure they don't contribute to the possibility of nuclear war is necessary. Our idea is that nuclear explosions should be studied and when appropriate carried out by an international institute according to the following principles. The institute is open to people from all countries. No information is kept secret.
All work is to be done safely.
Explosions are done when authorized by procedures established by an internationally representative review board. No weapons are to be designed or tested. Weapon design information is not to be present. Non-proliferation of weapons is to be advanced. If weapon information is needed for international arms control purposes, this information should be handled by a different organization.
