DEC 2 819/8 MEMORAtlDUM FOR: LWR Safety Improvements Review Group FROM:
R. DiSalvo, Chairman LWR Safety Improvements Review Group Probabilistic Analysis Staff Office of Huclear Regulatory Research
SUBJECT:
VALUE IMPACT RESEARCH A meeting to identify issues and potential technical approaches of research to improve value-impact methods was held (attachment).
This program is a key element of HRC's research to improve reactor safety.
The lead contractor is PHL with assistance from BCL and Sandia.
During the initial period of the program, the contractor will establish a technical approach which reflects the following considerations:
1.
Developers of the improved value-impact methods will specify the nature and desired accuracy of data input to the analysis and will generate a practical framework for combining those ingredients.
Investigators of individual concepts to improve safety will use this framework to provide, for their own concept, the engineering and cost data necessary to analyze its values and impacts.
2.
The pros and. cons of perfonning relative versus absolute value-impact assessments.
3.
Applicability of improvements ~ in value-impact methods to uses within HRC other than RES' investigation of improved reactor safety.
4.
The need to identify all. factors which might potentially affect the conclusions of a value-impact analysis, including those judged to be unquantifiable, irrelevant or inconsequential by the analyst, i.e.,
values othr. than public risk reduction potential and impacts other than cost of implementation).
5.
Identification of value and impact measures which are independent of each other and of the alternative concepts for improving safety.
6.
The use of multiple measures of risk reduction potential (e.g.,
integral risk, most likely outcome, highest consequence accidents, latent and acute health effects) which reflect the spectrum of safety concerns of all parties interested in the analysis.
7.
The scope and sources of data used to assess the cost of improvements in safety (i.e., in addition to capital cost of construction).
8.
The time dependence and equity of both values and impacts.
79010804 9 6
. s LWR Safety Improvements Review Group 9.
Means of estimating the sensitivity of the conclusions of a value-impact analysis to the large uncerti..nties anticipated in the input data.
- 10. The pros and the cons of unweighted individual measures of value and impact versus weighted lumped measures (i.e., single value tradeoff) as an output of the analysis.
11.
Pursuit of novel techniques (i.e., other than multi-attribute decision analysis) for potential development and application.
- 12. Methods for addressing particular concepts to improve safety which may not fall neatly into the generic value-impact framework being developed.
These and other factors will be considered by PNL over the next several months.
They have requested that the LWR Safety Improvements Review Group review their findings and recommendations at the end of that time before they proceed further.
Please provide me any comments you might have or any notation of issues you consider to be potentially significant, but are not included on the above list, so that I may relay your concern to the principal investigators.
