Deep geologic repository progress—2025 Update
Editor's note: This article has was originally published in November 2023. It has been updated with new information as of June 2025.
Outside my office, there is a display case filled with rock samples from all over the world. It contains a disk of translucent, orange salt from the Waste Isolation Pilot Plant near Carlsbad, N.M.; a core of white-and-bronze gneiss from the site of the future deep geologic repository in Eurajoki, Finland; several angular chunks of fine-grained, gray claystone from the underground research laboratory at Bure, France; and a piece of coarse-grained granite from the underground research tunnel in Daejeon, South Korea.

A method is described to estimate deuteron-on-deuterium breakup neutron distributions at 0 deg using deuteron bombardment of 3He. Breakup neutron distributions are modeled with the product of a Fermi-Dirac distribution and a cumulative logistic distribution function. Four measured breakup neutron distributions from 6.15- to 12.0-MeV deuterons on 3He are compared with 13 measured distributions from 6.83- to 11.03-MeV deuterons on deuterium. Model parameters that describe d-3He neutron distributions are used to estimate neutron distributions from 6- to 12-MeV deuterons on deuterium.
