Cold Fission

notes on forced accelerated radiodecay

[See also warm fission; and mock cold fusion which is similar by particles and energies]

Cold fission is related to cold fusion because fusion typically involves secondary nuclear-particle release to remove the excess energy; But topically this is about accelerated nuclear elemental radiodecay, electron-induced etc. but not chained as in warm-fission ....

Forced-triggered radiodecay cold-fission, -cleaner than hot-fission spallation,- may be possible by methods used in contemporary cold fusion experiments, warping the inner electron orbitals by introduction of light nuclei, eg. deuterons; by methods used in piezoelectric sonoluminescence; by high energy accelerated electrons reaching the nucleus directly; by possibly 4He* antihelon, as it tends to stable especially against non-alpha subnucleons, though it will tend to mutually annihilate nucleons ....

* (asterisk indicates its antimatter-equivalent element: and primarily its nucleus.)

Thorium-232 alpha-drip, or better, Uranium-238,- or -233, -235, Plutonium-239, odd-numbered fissile radionuclides already near electron-capture, have 6-8 alpha-drips each 4-9 MeV, plus beta-drips: Th-232 alpha-drip is ~18KeV/nucleon, but once accomplished and following a 6-year half-pause, has four beta-drips and five alpha-drips more, quickly totalling 43 MeV = 184KeV/nucleon, 21% efficient and totally and operationally safer than 200 MeV of dirty hot-fission requiring critical mass-compaction ... clean and small-scalable for a more-atomic future.

Also, Several non-fissile radionuclides of potential power output up to 7%-hot per-nucleon (cf 100%-hot n+Pu-239):--

CLEANER, ALPHA-TYPE: (a >> 1011yr, low-β, no-σ)

* (Note that Tungsten was recently reclassified as 100% α-emitter, W-180+182+183+184+186 = 100%.)

But unlike the established fissile radionuclides, these alpha-types have no further (α β)-subsequents.

BETA-TYPE: (see warm fission potential Beta- and Gamma-chaining)

These have sub-mega to mega electron-volt, no neutrons, and, ready electrochemical handleability. Their output electrons exceed their 1s-orbital energies by factors ranging to thousands, ensuring many subatomic incursions, where negative electrons gain additional catalytic MeV's nearing positive nuclei already ripe for triggering, and so possibly self-sustaining, and charge-barrier controllable.

Beryllium-10 and Niobium-94 have the distinct advantage of beta-drip, But both are reactor-made only.

Zirconium-96 has the advantage of surplus energy ready-to-go but atomically stable just shy of radioactive: the nucleus encased in overburdening atomic electron orbitals upon its tendency to symmetric double-beta requiring double-initial energy-surplus.

Nickel-58 is by tunnel-electron-capture probably already involved in the cold-fusion reputation of the early '90's.

SOME ABUNDANT, POTENTIAL, LESSER DOUBLE-BETA TYPES: (Leaving out many lesser abundant, etc.)

NOTES:

(There is report of 4H quadritium metastability at 0.000MeV (sub-KeV), but little published corroboration.)
