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?

An alternate method to that of representing the drop size spectrum by a mean drop diameter in an iodine removal analysis of the containment spray system is presented. A discrete drop size distribution, which is obtained from a fit of a continuous distribution function to the drop size spectrum observed for the nozzles employed in the spray sys tem is used. A model for the calculation of the changes in this distribution due to drop coalescence and condensation of steam on the spray drops is derived. The results obtained from this analysis show that consideration of the drop size spectrum, condensation, and coalescence in the analysis of the spray system does not degrade the iodine removal effectiveness calculated for a typical Westinghouse reactor containment.
