Emergency arrangements
In the very unlikely event of an incident of at any of the UK sites, a four-phase response would immediately take effect, comprising:
The four phase response comprises
- the control of the accident at the site
- the assessment of the consequences arising from the accident, and alerting the relevant authorities and the public
- the introduction of countermeasures to minimise short and longer-term effects
- the return to normal conditions.
The emergency actions are focused on two zones
a) a zone immediately surrounding an installation, inside which arrangements to protect the public are planned in detail. The boundary of this zone is drawn according to the maximum credible foreseeable situation.
b) a secondary zone beyond the detailed emergency planning zone above. Although highly unlikely to be needed, emergency plans to respond must still be in place. However, specific arrangements can only be defined according to weather conditions at the time of the incident, and responses made accordingly.
It is the responsibility of the operator of a nuclear plant involved in an accident, to bring it under control and minimise any off-site effects. It is their obligation to assess the situation and give all guidance and countermeasures required to protect the public and the environment.
They are also responsible for notifying all the appropriate authorities.
