ANS panel discussion looks at nuclear’s place in maritime, energy, medicine, space
The applications of nuclear energy extend beyond providing power to the electrical grid. Advanced nuclear technologies may soon have new applications in oil and gas facilities, in hospitals and clinics, on the open seas, and on the moon.
A June 1 executive session, “How Nuclear Technologies will Shape the Future Energy Economy,” at the American Nuclear Society’s Annual Conference allowed experts have an open discussion on the future of nuclear advancements in multiple sectors.

A comparison has been made between a modest increase in fuel discharge burnup and repetitive end-of-cycle coastdowns as two near-term alternatives that may be used to improve utilization of resources for a pressurized water reactor on the once-through cycle. Four cases have been considered. The cases include two different burnup levels—present technology of 33 000 MWd/MTU and a 3000 MWd/MTU increase in design burnup to 36 000 MWd/MTU. At each burnup value a fuel cycle without coastdown and one with coastdown every cycle have been evaluated. For each of the four cases, computations have been made of uranium requirements, separative work requirements, and m/kWh(electric) costs. The analyses show that the improvements in resource utilization with end-of-cycle coastdown are modest (<2%). There may be little or no economic benefits. The gains from increased discharge burnup are primarily a reduced fuel cycle cost. Since individual utilities may not see benefits in uranium or separative work savings per se that do not also include dollar savings, implementation of coastdown on a nationwide basis may be difficult.
