Language in which you want to receive the document.


This document presents the requirements for the on-site emergency response facilities
(referred to hereinafter as the “ERF”) which are to be used in case of incidents or accidents
occurring on the associated Nuclear Power Plant (NPP). The ERF consists of the Emergency
Response Centre (ERC), the Technical Support Centre (TSC) and the Operational Support
Centre (OSC), as shown in Figure 1.
It establishes requirements for the ERF features and ERF I&C equipment to:
• coordinate on-site operational efforts with respect to safety and radioprotection;
• optimize the design in terms of environment control, lighting, power supplies and access
control of the ERF;
• enhance the identification and resolution of potential conflicts between the traditional
operational means and emergency means (MCR/SCR and ERF, operating staff and
emergency teams, operational procedures and emergency procedures);
• aid the identification and the enhancement of the potential synergies between the
traditional operational means and emergency means.
This document is intended for application to new nuclear power plants whose conceptual
design is initiated after the publication of this document, but it may also be used for designing
and implementing ERF in existing nuclear power plants or in any other nuclear facility.
Detailed equipment design is outside the scope of this document.
This document does not define the situations (reactor plant conditions, hazards and
magnitudes of hazards) leading to mobilisation of emergency response teams and activation /
use of the ERF. These aspects are usually addressed in the NPP Emergency Plan. However,
the need for consistency of the ERF design and operation with the NPP Emergency Plan is
within scope.
