i. Heat exchangers (steam generators) specially designed or prepared for use in the primary coolant circuit of a "nuclear reactor";

A. whereas the British nuclear submarine HMS Tireless has been anchored in the port of Gibraltar since 19 May this year, after a leak was discovered in the reactor cooling system off the coast of Sicily, thanks to which over 200 litres of water from that cooling system were spilt over an expanse of more than 1200 miles,

S. whereas the repair process itself involves a risk, which is additional to the ones associated with the partial drainage of the primary circuit, the opening of the reactor compartment, the removal and storage of radioactive waste, the safety of the nuclear fuel and the actual repair to the damaged connection,

A. whereas the British nuclear submarine HMS Tireless has been anchored in the port of the colony since 19 May this year, after a leak was discovered in the reactor cooling system, and it had already undergone repairs for three years,

Others include: industrial safety accident rate; collective radiation exposure; chemistry performance, which is extremely important in a reactor, to ensure that there is appropriate and proper chemistry; fuel reliability in other words, fuel failures; thermal performance, which is how well the unit is performing; availability of emergency AC power, a backup in the event that something goes wrong; reliability of the auxiliary feedwater system; availability of the high-pressure injection system, which is used in case of an emergency, calculated, once again, on a rolling average; unplanned automatic scrams, or trips, of the reactor, ...[+++] calculated on a two-year rolling average.

These products come mainly from Malaysia, Singapore and Thailand, and consist chiefly of electronic equipment, e.g. integrated circuits, and nuclear turbo-reactors.
