CRP Specifics• Technical work by participants in the first three years of the CRP includes:

• Collaborative PIRT process

• Development of the benchmark scope

• Analysis of the benchmark

• Two unique long-term outreach objectives – Year 4&5 of CRP:

• Developing and conducting a PhD training programme on severe accidents

simulation and modelling in developing Member States through partnerships

between experienced Member States’ organizations and developing countries’ PhD

candidates.

• Outreach activities in year 4 and beyond include training newcomer countries on

State-of-Practice in Uncertainty and Sensitivity Methodologies for the Severe Accident

Analyses in Water Cooled Reactors through training workshops and fellowships.

Summary / Outlook

One of IAEA-NENP’s major goal is knowledge consolidation, organization

and dissemination to the wide audience of newcomer Member States:

• CRPs with newcomer participation

• Training courses and related publications

• Basic principle simulators (+ hands-on training)

• Searchable databases

• eLearning tools

NPTDS WCR Team intends to:

• Link its “learning tools” and databases internally AND, if possible, to

others, or include available information,

• Continue disseminating state-of-the-art knowledge on advancements in

WCR technology development and research through TMs, E&T WSs

and training courses, publications, development of tools and databases
