interest in the event of a reactor accident affecting Hong Kong. Further advice on dealing with the media and on setting up the Press Briefing Centre is given in Chapter 11 of this report.
6.7 Alerting the Emergency Organisation
In the event of an accident at Daya Bay, or an exercise, the emergency organisation will need to be alerted. The most likely method by which the organisation will be alerted is by direct contact from the reactor operators. Only in exceptional circumstances would the initial alert come from an alarm signal from one of the installed monitoring stations. It is therefore important that a communications link should be established between the reactor operators and a permanently manned location in Hong Kong. It is recommended that this location should be the Royal Observatory. It is therefore necessary to install a reliable communications link between the Royal Observatory and the Daya Bay Command Centre. This link should be a telex supplemented by a telephone line. The link should be tested by the passage of a test message at least every month. The alarm signals from the installed monitoring stations should also be displayed at this position in the Royal Observatory. An audible and visual warning device should be used to attract the attention of the Royal Observatory staff if either there is an incoming message from Daya Bay, or an alarm signal from one of the monitoring stations.
In the event of the Royal Observatory being alerted by the reactor operators they should then alert the other relevant sections of the emergency organisation as set out in Table 6.1. If the Royal Observatory is alerted due to confirmed high radiation readings on one or more of the installed monitors (see Chapter 8) they should assume that there is an 'off-site emergency' situation unless other information to the contrary is available. Alerting of other sections of the emergency organisation should be via a telephone cascade system. Such a system should be tested by the passage of a test message at least twice every year.
Consideration must also be given to how the required personnel at each of the emergency centres could be mustered at short notice, say one hour, during silent hours. It is likely that this will be best achieved by a telephone call out procedure augmented by radio-paging for key personnel. See also comments in Section 12.2.
