Abstract

En lettvanns kjernereaktor som avleder størstedelen av sin energi fra thorium, utnytter et frø-teppe- kjerne-arrangement og et ikke-parasittisk og meka- nisk forenklet kontrollsystem. Hverken det initialt innførte brennstoff eller brennstoffet avgitt fra reaktoren er anvendbart for kjernevåpenformål. Det initiale spaltbare brennstoff er anriket uran, U-235/U-238 (20:80), som er kjent for å være ikke- formerende. Det avgitte brennstoff består av (1) uran med ca. 10% U-235-innhold, (2) mindre enn 1% av mengden av plutonium som produseres i konven- sjonelle lettvannsreaktorer, (3) U-233 som er de- naturert ved at det er jevnt blandet med mer enn dobbelt så meget U-238, og (4) gjenværende thorium. Ca- 75-80% av reaktorenergien er avledet ved spalt- ning av U-233 dannet i thoriumet, og således unngås den meget kostbare prosess å ekstrahere og frem- stille høyt gamma-aktivt U-233 til brennstoff- elementer.A light-water nuclear reactor that derives most of its energy from thorium utilizes a seed-carpet core arrangement and a non-parasitic and mechanically simplified control system. Neither the initially introduced fuel nor the fuel delivered from the reactor is usable for nuclear weapons purposes. The initial digestible fuel is enriched uranium, U-235 / U-238 (20:80), which is known to be non-propagating. The fuel released consists of (1) uranium with approx. 10% U-235 content, (2) less than 1% of the amount of plutonium produced in conventional light water reactors, (3) U-233 which is degraded by mixing evenly with more than twice as much U-238, and (4) remaining thorium. About 75-80% of the reactor energy is derived from the decomposition of U-233 formed in the thorium, thus avoiding the very costly process of extracting and producing high gamma-active U-233 for fuel elements.
