Apport AIEA pour le Scoping<br />
L’AIEA visualise le processus de Scoping comme suit :<br />
For all plant system, structure or<br />
component (SSC), identify<br />
applicable information sources<br />
(process the SSC through each part)<br />
Is the SSC<br />
Safety Related<br />
YES<br />
Is the SC<br />
replaced or<br />
refurbished on<br />
a specified time<br />
interval<br />
NO<br />
SC subject to <strong>LTO</strong> review<br />
NO<br />
YES<br />
Does nonsafety<br />
related<br />
SC failure<br />
impact safety<br />
functions<br />
YES<br />
NO<br />
Not subject to <strong>LTO</strong><br />
Requirements of the current design basis are valid ISI/S/T, monitoring, maintenance,<br />
refurbishments and reconstructions within the framework of normal plant life management<br />
Implementation of the regulation for the evaluation of maintenance effectiveness<br />
(applicable to countries with Maintenance rules)<br />
