NUCLEAR EXPLOSIVES; APPLICATIONS THEREOF (electric or magnetic analogue computers, e.g. simulators, for nuclear physics G06G 7/54)
Definition statement
This subclass covers:

Explosives generated by uncontrolled nuclear reactions, e.g. nuclear fission and fusion bombs, and applications thereof.

Informative references
Attention is drawn to the following places, which may be of interest for search:

Explosive chemical composition

Methods for stimulating production of oil, gas, water, soluble or meltable materials or a slurry of minerals from wells by use of explosives

Conventional explosive devices

So-called "dirty bombs" where conventional explosives are used to dispense radioactive substances

Nuclear fusion reactors (i.e. controlled nuclear fusion)

Nuclear fission reactors (i.e. controlled nuclear fission)

Individual measuring devices may be classified as the measuring device per se

Analogue computers for simulating nuclear explosions

Nuclear power plant

Special rules of classification within this subclass

Classification of both important (invention) information and additional information is obligatory.

Glossary of terms
In this subclass, the following terms (or expressions) are used with the meaning indicated:

Uncontrollable reaction

Any fission or fusion reaction where event initiators (e.g. neutrons in the fission process) are produced in a number greater than required to sustain a chain reaction and where there is no mechanism to selectively moderate the reaction, e.g. a fission reactor where the operator has simply opted not to moderate or has failed to moderate the reaction is not a nuclear explosive device in the context of this subclass

Synonyms and Keywords

In patent documents the following words "device" and "bomb" are often used as synonyms.

In patent documents the following expressions "thermonuclear bomb", "hydrogen bomb", "H-bomb" and "fusion bomb" are often used as synonyms.

In patent documents the following expressions "A-bomb", "atom bomb" and "fission bomb" are often used as synonyms.

Peaceful applications of nuclear explosive devices {(obtaining oil, gas, water, soluble or meltable material from deep wells by means of nuclear energy E21B 43/2635, E21B 43/2403)}
References relevant to classification in this group
This group does not cover:

Obtaining oil, gas, water, soluble or meltable material from deep wells by means of nuclear energy

Special rules of classification within this subclass/group

This group is intended to cover future, yet unknown, inventions that fall under the definition of the group title. Examples for illustrative purposes include excavation processes through nuclear explosions, and systems for mining geothermal energy utilising the detonation of a deeply buried nuclear device to produce a chimney cavity and fractures in a rocky geothermal stratum.
