Construction Design Of Ebr Ii

The Argoune Experimentul Breeder Reactor-II is a completely integrated nuclear power plant which employs an unmoderated reactor as a heat source, and generates 20,000 kw of electricity. The integrated nuclear plant includes the fuel re-processing and fabrication cycle and thereby makes a signigicant contribution to power reactor techaology by operating on recycled fuel. The preliminary design of this plant was described at the First International Conference on the Peaceful Uses of Atomic Energy in 1955. Although the basic design concept and objectives have remained unchanged, many modiflcations have been made in the detailed design, including separation of the facility into several plants and providing containment for the reaetor system. The plant capacity and basic power cycle have rematned essentially unchanged: 62.5 Mw thermal, 900F reactor sodium outlet temperature, and 1250-psig steam at 850F at the turbine throttle. The feed-water te mperature, however, has been increased to 550F to reduce thermal stresses in the steam generator. (auth).
