Risk assessment – scope and goals
• Assessment of major accidents in non-nuclear fuel chains with
focus on the severe ones. The basis for this work is PSI’s database
ENSAD.
• In addition, an extension of the database including identification
and acquisition of new sources will be performed.
• Specific survey of historical data considering smaller accidents.
• Development of a concept for experience- and prediction-based
dam risk assessment.

Severe Accident Definition
(as used in ENSAD)
One or several of the following consequences:
• At least 5 fatalities
• At least 10 injured
• At least 200 evacuees
• Extensive ban on consumption of food
• Release of hydrocarbons exceeding 10000 tonnes
• Enforced clean-up of land and water over an area of at least 25 km2
• Economic loss of at least 5 million USD

NewExt-Project, 13./14.09.2001, Bath (UK)
Some methodological issues
•
Definition of a severe accident that could be consistently applied to various
energy chains.
•
Distinction between the estimates based on actual experience and on
predictions utilizing logical system models.
•
Treatment of source data and the rational for screening.
•
Accounting for contributions from all stages of fuel cycles.
•
Role of risk perception/risk aversion.
•
Presentation of results.

Severe vs smaller accidents
• A severe accident should have one or several of the following consequences:
- At least 5 fatalities
- At least 10 injured
- At least 200 evacuees
- Extensive ban on consumption of food
- Release of hydrocarbons exceeding 10000 tonnes
- Enforced clean-up of land and water over an area of at least 25 km2
- Economic loss of at least 5 million USD
 A smaller accident does not match any of the above criteria

NewExt-Project, 13./14.09.2001, Bath (UK)
Treatment of smaller accidents
• Use of extended ENSAD database as a starting point
• Use of additional sources:
- Occupational Health & Safety statistics
- NEWCRONOS database by EUROSTAT
- International Labour Organization statistics
- etc
Paul Scherrer Institut • 5232 Villigen PSI
NewExt-Project, 13./14.09.2001, Bath (UK)
Economic valuation
• To what extent are non-nuclear accidents already internalized?
- Differences between specific energy chains
- Occupational vs public accidents
- Small vs large accidents
• Basis for monetisation
- Value of statistical life
- Damages other than loss of life

Tasks for next 6 months (+)
1. Implementation of database extension up to year 2000
2. First evaluations based on extended database
3. Data acquisition for smaller accidents
4. Initialization of hydropower analysis
5. Partner contributions to monetisation
