The Special Materials Experiment was conducted at the Oak Ridge National Laboratory (ORNL) during 1992 as the final experiment in a series of eight experiments conducted for the Japanese-American Shielding Program for Experimental Research (JASPER) program that started in 1986. This experiment completes the experimental program providing support for the development of current designs proposed for advanced liquid metal reactor (LMR) systems both in Japan and the United States. The Tower Shielding Reactor II (TSR-II) source was modified to provide a neutron spectrum that would be typical of that to be found both radially and axially surrounding the LMR core. The experimental program plan was divided into two phases. In phase I, the mockups consisted of stainless steel followed by slabs of polyethylene and zirconium. For phase II, the stainless steel and zirconium were eliminated, leaving only the different thicknesses of polyethylene. Integral neutron flux measurements were obtained behind each of the mockups accompanied by spectral measurements for each configuration except one
