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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

PG&E to dredge Diablo Canyon intake system
The owners of the Diablo Canyon nuclear power plant plan to dredge a massive buildup of shoaled sediment from its seawater intake cove.
Pacific Gas and Electric spokesperson Suzanne Hosn said, “The dredging project in the Diablo Canyon marina will remove approximately 70,000 cubic yards of sediment to prevent circumstances that could impact the power plant’s cooling system. Dredging will take place for the first time since operations began because of a rapid increase in sediment.”

The Quarter Port Submodule (QPS) was proposed as a Solid Breeder (SB) Test Blanket Module under the US program of the SB blankets. The QPS features layer configuration, in its left half, where the SB pebble beds are parallel to the first wall and edge-on configuration, in its right half, where the SB pebble beds are perpendicular to the first wall. The objective of this study is to investigate: (i) the QPS thermal profile under steady state conditions and ITER transient loads, and (ii) the impact of the interface conductance h on the QPS thermal profile. In addition the effect of lack of contact, at the SB pebbles/structure interface, on the QPS thermal profile is presented. The results of the steady state cases showed that h has a significant impact on the QPS thermal profile. The QPS transient analysis provided results on: (i) QPS thermal profile under a pulse length of 400s, (ii) burning time required for reaching the equilibrium temperatures, and (iii) time needed to cool the QPS. In the cases of lack of contact, the maximum temperature of the SB pebble beds exceeded the SB temperature limit, which may cause sintering of the pebbles and consequently inhibit the tritium release.
