NNSA awards BWXT $1.5B defense fuels contract
The Department of Energy’s National Nuclear Security Administration has awarded BWX Technologies a contract valued at $1.5 billion to build a Domestic Uranium Enrichment Centrifuge Experiment (DUECE) pilot plant in Tennessee in support of the administration’s efforts to build out a domestic supply of unobligated enriched uranium for defense-related nuclear fuel.

In the Kuosheng nuclear power station, a turbine-driven reactor feedwater pump (TDRFP) is used to drive feedwater to the reactor pressure vessel (RPV). The performance of the TDRFP plays an important role in the safe operation of the nuclear power station as it governs the water inventory in the RPV. The dynamics of the TDRFP in the Kuosheng nuclear power station are simulated, and related parameters are identified by the simplex search method. A reactor feedwater pump (RFP) trip test was performed during the startup test of the Kuosheng nuclear power station. This RFP trip transient was selected for this study because it simplifies the identification process. The ratio of rated torque to moments of inertia, parameters related to the characteristic H-Q curve, and parameters related to the characteristic T-Q curve are verified.
