1 ARIES IFE - Some Concluding Comments on Thick Liquid Walls Wayne Meier, Ryan Abbott, Jeff Latkowski, Ralph Moir, Susana Reyes ARIES Project Meeting September 4-5, 2003 Georgia Tech Work performed under the auspices of the U. S. Department of Energy by University of California Lawrence Livermore National Laboratory under Contract W-7405-Eng-48

2 ARIES-IFE work and interactions with other OFES funded work on thick liquid chambers has been interesting and beneficial Re-examined structural material options Determined economic impact of FW replacement if need Updated mechanical design and developed maintenance sequence Facilitated workshop on liquid chamber dynamics Produced new views on recycling target material Improved final focus magnet shielding designs

3 Structural material options were considered ARIES report primarily recommended FS for better neutron life Some prefer Ni containing alloys (e.g., 304SS) for corrosion resistance, but modified to increase rad damage life (like 316 was modified to make PCA) Liquid wall thickness is an important design knob Needs: continued development of FS and modified SS, neutron damage and corrosion tests

4 Economic impact of FW replacement (if required) is acceptable; goal of lifetime components remains Meier, Abbott Oct 2002 Project Meeting

5 ARIES IFE and Robust Point Design study motivated new work on chamber mechanical design Disassembled chamber

6 RPD-2002 fusion chamber design report just completed

7 Target material recycling was examined Target factory designers would like to avoid dealing with recycled, activated hohlraum materials Environmental assessments support feasibility of a no-recycle approach El-Guebaly Oct 2002 Project meeting

8 Final focus magnet shielding designs were improved Latkowski May 2003 Project Meeting

9 ARIES IFE work should continue Promotes interactions within broad IFE community Brings new faces, new ideas into play Increases opportunity for synergy with other OFES funded work Continuation is supported by VLT Program Advisory Committee Needs: sufficient Advance Design Studies budget to support two studies (MFE and IFE)
