Dialogue Managing the Unexpected – Managing the Unexpected – the Role of the Regulatory Body

Cornelia Ryser, ENSI, Switzerland IAEA Technical Meeting Vienna, 25 – 29 June 2012

Assumptions

• The regulatory body, by nature, influences an operator‘s safety

and (safety) culture.

• The nature of this influence substantially depends on the

regulator‘s regulatory strategy and culture

• Also negative impact is possible.

2 Managing the Unexpected – Role of the Regulatory Body

• C. Ryser, ENSI, 26.6.2012
• The operator‘s ability to manage unexpected events depends

(among other things) on:

• its paradigm and culture of safety
• the context and conditions of operation (e.g. the regulatory

framework) The regulatory body also affects the operator‘s ability to manage the unexpected.

Some issues to discuss…

1. How does the regulatory body influence the operator’s ability to manage the unexpected?

• What kind of regulatory strategy and practice fosters the
• perator’s ability to manage the unexpected?
• What obstructs it?

4 Managing the Unexpected – Role of the Regulatory Body

• C. Ryser, ENSI, 26.6.2012

2. What does it mean for the Regulatory Body itself to be able to manage the unexpected?

• How can the Regulatory Body itself foster its own ability

to manage the unexpected? 3. How can the Regulatory Body assess the Operator’s ability to manage the unexpected?
