【 摘 要 】

The objectives of the first year of phase 2 of the program are to construct and operate an engineering pilot reactor for OTM oxygen. Work to support this objective is being undertaken in the following areas in this quarter: Element reliability; Element fabrication; Systems technology; Power recovery; and IGCC process analysis and economics. The major accomplishments this quarter were: (1) Methods to improve the strength and stability of PSO1x were identified. (2) The O1 reactor was operated at target flux and target purity for 1000 hours. This quarterly technical progress report will summarize work accomplished for Phase 2 Program during the quarter October to December 2002. In task 1 improvements to PSO1x have shown increased performance in strength and stability. In task 2, PSO1d and PSO1x elements have been fabricated for testing in the pilot reactor. In task 3, the lab-scale pilot reactor has been operated for 1000 hours. In task 6 initial power recovery simulation has begun. In task 7, HYSIS models have been developed to optimize the process for a future demonstration unit.
