The Framework

The Goal:

Nuclear energy to prosper in highly demanding and fast evolving (European) markets.

The Prerequisites:

Nuclear energy is safe (and perceived so by the society!)

Nuclear energy is competitive (all stakeholders!)

REMOO 2013, Belgrade, Serbia

14r4.ijs.si/en

Safe and perceived so by the society!

What?

• Better technologies and operating procedures

• Better trained technical staff

• Better understanding of risks, in relation to societal expectations

• Better risk prevention

• Better accident mitigation procedures and resources

• Better public information

Safe and perceived so by the society!

How?

• careful operating experience analysis: to learn from the past and identify precursor events

• research programmes: new knowledge for new approaches and solutions

• operator independent and science based cross-cutting expertise in support to safety authorities: to enable the regulatory process beyond static conformity, towards requirements for state of the art safety, security and radiation protection improvement

• Upgraded knowledge management and training resources

Competitive (all stakeholders)

Competitive (and safe) for decades, a century:

Anticipate, generate and adapt to huge technical progress

Anticipate, generate and adapt to huge changes in the society

Vigorous strategy for longtern promotion of:

Research

(Higher) Education

Safety culture

The Framework

The Goal:Nuclear energy to prosper in highly demanding and fast evolving (European) markets.

The Prerequisites:Nuclear energy is safe and perceived so by the society!

Nuclear energy is competitive (all stakeholders!)

The Challenges:All stakeholders to work closely together and support each other to create and implement the necessary knowledge and knowhow. Longterm effort!

A lot of money and top level experts!

Reflections from REMOO 2012

Education and Safety Culture

Should post-Fukushima investments go beyond Improved Technology and include Education and Safety Culture?

Research and Safety Culture

Should sustainable developments of Safety and Safety Culture rely on Research (Best Available science)?

Promotion and Support

Should the nuclear industry publicly promote and support the Research and Education?

Summary

Nuclear energy could prosper in highly demanding and

fast evolving (European) markets, if:

• Safe AND perceived so by the society!

• Competitive (long term, all stakeholders)

All stakeholders to work closely together and support

each other to create and implement the necessary

knowledge and knowhow.

• A long term strategy and vigorous activity!

• Requires (a lot of) money and top level experts!
