CAN3-N289.1-80 (R2008)

Scope

1.1 General

This Standard sets forth the general requirements for seismic qualification of CANDU Nuclear Power Plants.
It applies to all structures and systems of the CANDU Nuclear Power Plant that require seismic qualification based on nuclear safety considerations.

1.2
This Standard may also be applied to such other structures and syst ems of a nuclear power plant as may be specified by the Owner, for reasons of economic concern or to meet additional requirements of the AECB. This will generally impose more restrictive design requirements than those of the National Building Code of Canada (NBCC). In any case, such other structures and systems shall be designed to meet at least the requirements of the NBCC, in order to ensure a minimum degree of resistance against collapse or failure, to mitigate the effects of earthquakes on nearby safety-related structures or systems.

1.3
Certain clauses may be applied, as appropriate, to research reactors or other nuclear facilities coming within the jurisdiction of the Atomic Energy Control Act, e.g., heavy water plants and waste management disposal facilities.
