OSTI ID:5984421
In the Task Action Plan for Unresolved Safety Issue A-45 (After-Heat Removal) it was recognized that the value-impact (VI) analysis of possible solutions would be an essential part of the work, particularly in the later stages. Accordingly, a review of existing methods and development of a methodology to meet the specific requirements of TAP A-45 was undertaken. In this report each of the principal areas of work is described. Due to the high capital costs associated with major changes to DHR systems, values arising from avertable ''offsite costs'' (i.e., the costs of the potential effects on the health and safety of the public, both direct and indirect) would be insufficient to justify any significant changes to DHR systems simply on the grounds of cost effectiveness. Therefore, a major part of the work reported here has been a study of possible additional avertable costs that should properly be included in the ''value'' term of the V-I analysis.
