Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

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.
