    This is the Final Report for a three-year (FY 92--94) study of the Environmental, Safety, and Economic (ESE) aspects of fusion energy systems, emphasizing development of computerized approaches suitable for incorporation as modules in fusion system design codes. First, as is reported in Section 2, the authors now have operating a simplified but complete environment and safety evaluation code, BESAFE. The first tests of BESAFE as a module of the SUPERCODE, a design optimization systems code at LLNL, are reported in Section 3. Secondly, as reported in Section 4, the authors have maintained a strong effort in developing fast calculationalmore » schemes for activation inventory evaluation. In addition to these major accomplishments, considerable progress has been made on research on specific topics as follows. A tritium modeling code TRIDYN was developed in collaboration with the TSTA group at LANL and the Fusion Nuclear Technology group at UCLA. A simplified algorithm has been derived to calculate the transient temperature profiles in the blanket during accidents. The scheme solves iteratively a system of non-linear ordinary differential equations describing about 10 regions of the blanket by preserving energy balance. The authors have studied the physics and engineering aspects of divertor modeling for safety applications. Several modifications in the automation and characterization of environmental and safety indices have been made. They have applied this work to the environmental and safety comparisons of stainless steel with alternative structural materials for fusion reactors. A methodology in decision analysis utilizing influence and decision diagrams has been developed to model fusion reactor design problems. Most of the work during this funding period has been reported in 26 publications including theses, journal publications, conference papers, and technical reports, as listed in Section 11.« less

    This document is a proposal to continue the authors work on the Environmental, Safety and Economic (ESE) aspects of fusion reactors under DOE contract DE-FR03-89ER52514. The grant objectives continue those from the previous grant: (1) completion of first-generation Environmental, Safety and Economic (ESE) computer modules suitable as integral components of tokamak systems codes. (2) continuation of work on special topics, in support of the above and in response to OFE requests. The proposal also highlights progress on the contract in the twelve months since April, 1992. This has included work with the ARIES and ITER design teams, work on tritiummore » management, studies on materials activation, and calculation of radioactive inventories in fusion reactors.« less

  • This report discusses the following topics: graphical representations of environmental and safety indices; revised computational modeling of radiological doses; plasma emergency shutdown for ITER; radiological doses of ARIES-type reactors; neutronics database; scale formulation of radioactivity in SiC first wall; evaluation of tritium inventory by dynamic simulation; and probabilistic risk assessment.

  • The objectives of the Berkeley Fusion (ESE) Program, as stated in the original grant proposal, fall into two categories: special topics, including those identified as needing additional work by the Senior Committee on Environmental Safety and Economic Aspects of Magnetic Fusion Energy (ESECOM); computerization of ESE data, to put Environmental, Safety and Economics (ESE) information in a form suitable for incorporation in major reactor design codes. This is expected to be a long-term effort, extending at least through the duration of the present 3-year grant. To insure that our output is of the greatest ultimate use, the Berkeley group ismore » maintaining close contact with the ongoing US major design efforts, ITER and ARIES, and also European and Japanese activities in the ESE area.« less
