ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

Titanium was selected for evaluation as a tritium storage material. Titanium-deuterium desorption isotherm data at 550, 600, 649, 700, and 760°C are presented and were used to evaluate storage vessel design loading limits. Two prototype Hydride Storage Vessels (HSVs) containing a nominal 4400 grams of Ergenics HY-STOR 106™ titanium sponge were tested to determine activation, loading, and desorption conditions. HSV titanium activation was performed using two methods. The first was vacuum evacuation using stepped temperature holds up to 600°C. The second, and preferable method, was a dry gas purge for several hours at up to 350°C followed by heated evacuations at temperatures up to 600°C. The vessels were allowed to sit idle after activation for five days before loading to determine the quality of the activation process. HSV gas loadings were performed through the process tube inserted into the hydride at 5, 7.5, 10, 15, 20 SLPM, and under conditions to simulate direct loading from a 1500 liter process tank. Temperature measurements made at various locations around the vessel showed the internal maximum temperature ranged from 500°C to 700°C and varied with loading rate. Maximum external temperatures ranged from 300°C at 5 SLPM to 400°C at 20 SLPM. Loading the HSV at 20 SLPM from the tube above the level of the hydride generated at maximum internal temperature of 800°C. HSV desorptions were done under a variety of vacuum conditions at temperatures up to 700°C. HSV desorption/gas removal was greatly reduced at temperatures below 700°C, the use of one instead of both process tubes, and the choice of vacuum pumps. Integration of mass flow data was considered a more reliable method of determining HSV gas inventory than the use of titanium isotherm data. Up to 84 vol% of the gas inventory can be removed from the HSV by desorption in 24 hours, but tritium removal by isotopic exchange will be needed for vessel disposal - even if longer evacuation times were used.
