Cover gas seal components. [LMFBR]

The objectives of the Cover Gas Seal Component test program are to develop and demonstrate the performance of commercial and custom-designed head region cavity seals for LMFBR reactors, to develop and evaluate advanced seal concepts capable of achieving improvement in radioactive gas containment and seal temperature-life capabilities, and to establish operational safety margins for head region seals for nominal and extraordinary LMFBR plant conditions. During FY 1979, the major effort has been directed toward designing and analyzing concepts for flexing metal dynamic seals as alternate concepts to inflatable elastomer seals. In June, the program was redirected to concentrate on improving and simplifying fabrication techniques and designs of inflatable elastomer seals
