Une tentative américaine de construire un réacteur (Advanced Neutron Source) aux limites des possibilités a avorté. Pour aller au-delà, on se tourne donc vers une autre technique : la source à spallation. Celle-ci consiste à arracher des neutrons à des noyaux lourds (Hg, W, Pb, Bi...) au moyen de protons à haute énergie. Il n'est pas indispensable d'utiliser des cibles actinides, qui seraient encore meilleures mais produiraient des déchets bien plus radioactifs. 1, record 9, French, - source%20%C3%A0%20spallation

Ces systèmes fonctionnent avec des particules chargées accélérées (proton, deuton, ...) dans la gamme dite des énergies intermédiaires : de 20 MeV à plusieurs GeV. Ces particules chargées de grande énergie provoquent dans un matériau approprié fait d'atomes riches en neutrons, appelé cible de spallation, des réactions de spallation qui se manifestent par une fragmentation du noyau en plusieurs entités : des particules légères (neutrons, protons, ...) et des groupements de nucléons résiduels désignés par les termes de clusters, résiduels ou produits de spallation. 1, record 11, French, - syst%C3%A8me%20spallateur

Toute réduction de puissance cause un pic de xénon transitoire. Plus la réduction de puissance est faible, plus le pic est faible et plus il se produit rapidement. Par exemple, pour une réduction de puissance de 100 % à 60 %, il y a encore une production en excès initial par rapport aux pertes, mais un flux de neutron important demeure pour effectuer la combustion du xénon. La hauteur du pic et sa durée sont réduites, et le pic survient plus tôt. 1, record 16, French, - pic%20de%20x%C3%A9non%20transitoire

Any power reduction causes a transient xenon peak. The smaller the power reduction the smaller the peak, and the earlier it occurs. For example, on a power reduction from 100% to 60%, there is still an initial excess of production over loss, but significant neutron flux remains to burn out the xenon. The peak height and its duration are reduced, and the peak occurs earlier. 1, record 17, English, - power%20reduction

A specialized radioactivity log of neutron-gamma log type. A neutron generator produces short bursts of high-energy neutrons(about 14 MeV), which are slowed in the borehole and nearby rocks to thermal energy level(about 0. 025 eV) ;capture by nuclei(especially chlorine) results in gamma-ray emissions.
