25. IGALL Phase 4 Objectives
Objective 2 - Enhancement of AMR (WG1-3):
Column ‘further action’ – consolidate information in ‘further action’ column (other than TLAAs) and develop description of ‘further action’ intention, use descriptions of the further evaluations which are identified in the “further evaluation” column of the NRC GALL AMR table defined e.g. in SRP, part for improvement of IGALL
Task completed
Systematic review and consolidation of definitions for ‘structure/component’, ‘critical location/part’, ‘material’, and ‘environment’
In progress
Develop a pilot on use of EPRI MDM format to enhance AMR table
WG1 - Column ‘System’ – change title to ‘System/ functional group’ and agree and consolidate terminology

27. IGALL Phase 4 Objectives
Objective 4 - Specific tasks (WG4 and WG5):
Guidance for regulators to review NPPs` preparedness for safe LTO (WG dealing with Regulatory Aspects of LTO preparation).
In progress
Develop TECDOC experiences in ageing management during delayed construction periods, prolonged outages, extended shutdown and post final shutdown

Develop and implement workshop/ training for “junior” experts on IGALL use
In progress - IGALL-related workshops provided to NPPs and regulators in Argentina, Armenia, China, Iran, Pakistan, UK in 2018; Brazil, Bulgaria, Iran, Pakistan, Romania, Russia, Slovakia, Ukraine scheduled in 2019.
Improve IGALL public and restricted website
Task completed – simple modifications performed, more complex rejected by IAEA IT
Invite observers e.g., from new built companies, on a regular basis
In progress - Several IGALL WGs hosted by IGALL participating organization – observers from hosting organization always invited
AMR – hyperlink terms to definitions, AMPs and TLAAs on IGALL public website
In progress – presentation of Brazil to be provided

29. IGALL Programme Conclusions
IGALL Safety Report and IGALL database is available on IAEA web site
IGALL Phase 3 ( ) completed
