Upgrading of the K-reactor supplementary safety system at the Savannah River site
- Westinghouse Savannah River Company, Aiken, SC (United States)
In the event that safety rods fail to scram, the supplementary safety system (SSS) in the K Reactor at the Department of Energy's Savannah River Site nuclear materials production complex provides a second line of defense for attaining shutdown by injecting a neutron poison solution into the moderator space of the reactor tank. Recently the SSS has been upgraded with a secondary poison injection to remedy a potential deficiency of the original design during a drop of coolant flow as a result of a loss of a-c power to the coolant pumps. This article outlines the basis of the functional performance requirements (starting delay, input flow, and flow duration) for the secondary poison injection which ensure the effectiveness of the SSS for any anticipated transients without scram. 7 figs.
