It is shown that self-sinking of a spherical probe in the form of a capsule filled with radionuclides, whose decay heats and melts the rock in its path, deep into the Earth is possible. Information on the formation, structure, and shifts deep in the Earth can be obtained by recording and analyzing acoustic signals from the recrystallization of the rock by the probe. It is shown that such capsules can be placed at a prescribed depth. Self-sinking probes can be used to study the formation of deep… 

A new approach to radioactive waste self-burial using high penetrating radiation

ABSTRACT The method of self-burial of radioactive waste in geological formations using direct heating of rocks by radiation is proposed in this paper. In the currently known studies, thermal

Super-Deep HLW Self-Disposal Option -11065

The possibility of super-deep (below 5 km) self-disposal is analysed which is based on utilisation of radiogenic heat of decaying waste radionuclides from high-level radioactive waste (HLW) or spent

Self-disposal option for highly-radioactive waste reconsidered

Self-disposal option for heat-generating radioactive waste (HLW, spent fuel, sealed radioactive sources) known also as rock melting concept was considered in the 70s as a viable but alternative


A summary is presented of the potential of non-destructive acoustic emission (AE) method to be applied for structures immobilising nuclear wastes. The use and limitations of the method are discussed

Executive Summary: "Mantle Frontier" Workshop.

Theory of Earth

The maturing of the Earth sciences has led to a fragmentation into subdisciplines which speak imperfectly to one another. Some of these subdisciplines are field geology, petrology, mineralogy,

Melting Around a Migrating Heat Source

The problem of melting around a moving heat source arises in many different situations such as nuclear reactor technology (i.e., “self-burial” process of nuclear waste materials and reactor core

Experimental evidence that potassium is a substantial radioactive heat source in planetary cores

High-pressure, high-temperature data presented here show conclusively that potassium enters iron sulphide melts in a strongly temperature-dependent fashion and that 40K can serve as a substantial heat source in the cores of the Earth and Mars.

Planetary science: Mission to Earth's core — a modest proposal

A scheme for a mission to the Earth's core, in which a small communication probe would be conveyed in a huge volume of liquid-iron alloy migrating down to the core along a crack that is propagating under the action of gravity.

Granite recrystallization: The key to the nuclear waste problem?

We report the outcome of high-temperature, high-pressure experiments showing that granite can be partially melted and completely recrystallized on a time scale of years as opposed to millennia as

A case is presented for reconsidering deep borehole disposal for high‐level radioactive waste (HLW) in the light of recent discoveries about the hydrogeology and hydrogeochemistry of the continental


An increase in the efficiency and economy of the decontamination of liquid radioactive wastes by an ion exchange process can be attained by improvement in its technology and instrumentation. Pulsed
