Alpr Preliminary Design Study (Argonne Low Power Reactor). Phase I

Design of the Argonne Low Power Reactor (Alpr)

“…Features of the reactor core design that were considered to have had important influences on the stability of operation of the BORAX reactors were essentially retained in the ALPR core. (2,3) in particular, in view of the proved stability of power operation of the aluminum-U-HjO BORAX cores, and since no experience had been garnered with boiling water reactors fueled with steel-clad fuel plates or rods in a steel core structure, aluminum was used as the basic metal constituent of the core. (Moreover, it was estimated that the use of aluminum would result in a reactor core less expensive than a steel system.…”
