Title: Terminal report, Pluto program at Atomics International

Abstract

Declassified 26 Nov 1973.<>29:020142Declassified 28 Nov 1973. onstrate the performance on a full-scale reference SNAP 2 fuel element when subjected to an environment which simulated the most severe conditions (i.e., peak temperature, burnup, and burnup rate) encountered in a SNAP 2 reactor core upgraded to produce 125 kW(t). This experiment was irradiated for twentythree reactor cycles in the Materials Testing Reactor and was discharged on August 18, 1965. The fuel element achieved its de sign peak burnup of 0.08 metal at.% in an equivalent of one year at full power. The design peak cladding temperature of 1300 deg F (which is nominally equivalent to a peak fuel temperature of 1507 deg F) was maintained within plus or minus 50 deg F during 93.4% of the time that the reactor was at full power. The post-irradiation condition of the fuel element and the irradiation assembly was excellent. Both the uranium--zirconium hydride fuel rod and the Hastelloy-N cladding were intact and in excellent condition. The performance of the fuel element, in terms of suitability for use under 125 kW(t) SNAP 2 reactor conditions, was completely satisfactory. The design, analysis, fabrication, in-pile operation, and post-irradiation examination and evaluation of the NAA 82-1 experimentmore » are described. (27 references) (auth)« less
