Reboot: Nuclear needs a success . . . anywhere
The media have gleefully resurrected the language of a past nuclear renaissance. Beyond the hype and PR, many people in the nuclear community are taking a more measured view of conditions that could lead to new construction: data center demand, the proliferation of new reactor designs and start-ups, and the sudden ascendance of nuclear energy as the power source everyone wants—or wants to talk about.
Once built, large nuclear reactors can provide clean power for at least 80 years—outlasting 10 to 20 presidential administrations. Smaller reactors can provide heat and power outputs tailored to an end user’s needs. With all the new attention, are we any closer to getting past persistent supply chain and workforce issues and building these new plants? And what will the election of Donald Trump to a second term as president mean for nuclear?
As usual, there are more questions than answers, and most come down to money. Several developers are engaging with the Nuclear Regulatory Commission or have already applied for a license, certification, or permit. But designs without paying customers won’t get built. So where are the customers, and what will it take for them to commit?

A generic computer model has been developed for the dynamic simulation of the radwaste evaporator system in nuclear power stations. The waste evaporator system is designed to receive dilute radioactive waste and to produce distillate and concentrated waste. The generic system component models developed include a submerged tube evaporator, a plate-type absorber, a partially submerged tube condenser, and the interconnecting piping. The system component models have been integrated with Bechtel’s Dynamic Analysis Program to simulate the system’s dynamics. To illustrate the application of the model, the dynamics of an adjustment to the condenser cooling water flow valve have been simulated and presented. This presentation illustrates the strong potential of the model for solving control problems in new and operating radwaste evaporator systems. Potential applications of the computer model to radwaste evaporator systems include troubleshooting, optimization of control parameters, and automation of control functions.
