First GAIN vouchers of 2025 go to Curio, Deep Fission, Kairos, and NuCube Energy
The Department of Energy’s Gateway for Accelerated Innovation in Nuclear (GAIN) has awarded four fiscal year 2025 vouchers to support the development of advanced nuclear technologies. Each company will get access to specific capabilities and expertise in the DOE’s national laboratory complex—in this round of awards both Idaho National Laboratory and Pacific Northwest National Laboratory are named—and will be responsible for a minimum 20 percent cost share, which can be an in-kind contribution.

The very first work on RETRAN model development and its application to plant design study for the Lungmen nuclear power station (LMNPS) is presented. Lungmen is the fourth nuclear power plant of the Taiwan Power Company (TPC). LMNPS has two advanced boiling water reactor (ABWR) units, each with a thermal power of 3926 MW. The preliminary safety analysis report (PSAR) of LMNPS is currently under review. The Lungmen RETRAN-02/MOD5 model was developed to provide support to TPC in the PSAR review and system design study. An analysis of generator load rejection with failure of all bypass valves was performed against the analysis in the PSAR to benchmark the Lungmen RETRAN model. One of the specific designs of LMNPS is that the reactor has the capability to withstand a full-load rejection or a turbine trip event without a reactor scram. An analysis of generator load rejection with all bypass valves was done to evaluate this design. The results show that this design is appropriate.
