§ Lord Kennetasked Her Majesty's Government:
Whether they intend that tritium should be included in the ban on the production of fissile material, and whether there are any other materials that in their view can be used in nuclear weapons or other nuclear explosive devices that could usefully be banned.
§ The Parliamentary Under-Secretary of State, Ministry of Defence (Lord Henley)The United Kingdom will participate fully in the negotiations which are likely to begin shortly on a convention to ban the production of fissile material for nuclear weapons or other explosive purposes. The coverage of the convention will be a matter for discussion between participating nations. Non-fissile materials such as tritium will not, however, be included.
