The UK Government certifies that reactor safety aspects of design, crew training and operating procedures of the nuclear propulsion plants of UK nuclear-powered warships are reviewed by the UK Nuclear-Powered Warships Safety Committee and other appropriate UK authorities, and are as defined in officially approved manuals. The UK Government also certifies that all safety precautions and procedures followed in connection with operations in UK ports will be strictly observed in foreign ports.

2. In connection with the operation of UK nuclear-powered warships in foreign ports:

1. (a) No effluent or other waste will be discharged from the ship which would cause a measurable increase in the general background radioactivity of the environment; waste disposal standards are consistent with the recommendations of the International Commission on Radiological Protection.

2. (b) During the period of the visit, the personnel of the nuclear-powered warship will be responsible for radiological control on board the ship and for environmental monitoring in its immediate vicinity. The host Government may, of course, take such surveys as it desires, in the vicinity of the warship, to assure itself that the visiting ship is not creating a radio-active contamination hazard.

3. (c) The appropriate authorities of the host Government will be notified immediately in the event of an accident involving the reactor of the warship during a port visit.

4. (d) The UK Government assumes the responsibility to salvage or otherwise make safe any nuclear-powered warships that might be incapacitated in a foreign port.
