To Whom It May Concern:

I, Roy F. Schall, Jr., Ph.D., former director of research for clinical and diagnostic instruments and reagents and holder of an earned Doctorate in Nuclear Chemistry (1969) from Carnegie Mellon University, Pittsburgh, PA, have witnessed and evaluated a method for disposal of highly radioactive waste designed and in development by Dean S. Engelhardt of Los Angeles CA. The method involves encapsulating this extremely dangerous waste in a stainless steel vessel of special design. The filled capsule is then dropped into the mud at a tectonic plate subduction zone of the earth's crust where in a short geological time it will be drifted with the continental plate under the crust of the earth where its chemical and radioIogical toxicities will lie harmless for the ages.

I consider this idea to be an excellent method of disposal for these dangerous byproducts of nuclear fission. The depths of water where continental plate subduction occurs is so great that retrieval by man would be most difficult and expensive once the capsule has been dropped or lowered. Once the capsule is embedded into the mud at the bottom of the ocean, it will sink slowly further into the mud making it harder to retrieve. The capsule or vessel itself is of novel design and will compress and strengthen as pressure rises around it at great water depth. In time, movement of the subducting crust will sweep along the capsule underneath a continental plate where it will become impossible to retrieve and safe from accidental or intentional retrieval. Use of salt water resistant materials for the capsule will ensure that corrosion will not release the contained waste until it is finally buried where it can do no harm.

This method seems a practical, safe and inexpensive method for high level, long lived radioactive waste disposal when compared to current methods being contemplated and developed.
