LLNL, Ampera partner to develop thorium-based TRISO fuel
Lawrence Livermore National Laboratory has formed a strategic partnership with Ampera to develop the company’s nuclear fuel concept through a project named THUNDER, for Thorium Unimodal Droplet Ejection for Reactors.
The focus of THUNDER is fabricating TRISO made with kernels of thorium rather than the usual uranium. LLNL and Ampera will evaluate and optimize liquid metal–jetting technology to produce highly uniform, spherical kernels of thorium-232 for later processing into TRISO fuel.

Cladding ruptures of Caramel-type fuel rods, such as the ones now being used in the OSIRIS Experimental Reactor in the Saclay Nuclear Center, were studied to evaluate the risks from fission products and fissile materials released if the cladding of a fuel rod is broken. The study was conducted on the cladding rupture detection system in the EL3 Reactor during April 1978. Results show the cladding rupture detection system to be very sensitive; the cladding rupture development until the reactor stops in an emergency is small enough to have only negligible radiologic consequences on OSIRIS installations. Le texte expose les résultats d’un essai de suivi de rupture de gaine sur un élément combustible du type Caramel qui équipe dorénavant le réacteur expérimental OSIRIS du Commissariat à I’Energie Atomique Saclay. Cet essai CARINE, réalisé dans le réacteur EL.3 en Avril 1978, a permis d’essayer le système de detection de rupture de gaine et d’évaluer les risques de relâchement de produits de fission et de matières fissiles, si la gaine de l’élément combustible est ouverte. Le système de détection de rupture de gaine s’est révélé très sensible, le développement de la rupture de gaine jusqu’à I’arrêt d’urgence du réacteur est suffisamment limité pour n’avoir que des conséquences radio logiques négligeables sur les installations d’OSIRIS.
