Abstract

"The use of isotopes to include radioactive waste products to reduce the neutron-induced activity of an underground nuclear explosion and its application in the field of geothermal power stimulation is discussed. A shield composed of selected isotopes surrounding a fusion device will capture excess neutrons producing isotopes with short half-lives. Subsequent rapid decay will prolong the high temperature in the vicinity of the explosion and decrease the activity. Long-lived isotopes created by neutron capture in the host rock would be minimized. The investigation is conducted for strontium-90, cesium-137, cerium-144, technetium-99, rhodium-103 and -105. Of these, the first three appear to be presently unacceptable due to their physical properties and restrictions imposed during the investigation. Rhodium-105 is unacceptable due to its short half-life. The remaining two were determined to be acceptable although comparatively expensive. Recommendations are proposed to further study this concept for the disposal of radioactive waste as well as power production"--Abstract, page ii.
