Scoping tests on the potential for lithium/aluminum steam explosions in an SRS Septifoil

In May 1991, WSRC/SRL requested that ANL conduct five scoping tests in order to investigate the potential for self-triggered lithium/aluminum steam explosion in an SRS Septifoil. This work was to support the ongoing SAR Chapter 15 analysis for the K-reactor restart at SRS. The five tests were successfully completed over a two-month period between June and August 1991. The conditions for the five tests were specified by the WSRC designated technical manager, Dr. Phillip G. Ellison. While the tests were carried out in an existing facility at ANL, WSRC/SRL provided the test sections which consisted of a three-foot long SRS Septifoil section including webbing, bottom endfitting, and eleven-inch long control rod segments. In addition, WSRC/SRL supplied the lithium/aluminum alloy required for the tests.
