Posiva begins drilling disposal holes at Finland’s Onkalo repository
Last week the Finnish nuclear waste management company Posiva began drilling holes for final disposal at the Onkalo deep geological repository, near the Olkiluoto nuclear power plant in western Finland. The company’s German-made Deposition Hole Boring Machine (DHBM) took about 10 hours to drill the first hole, with a depth of 8.4 meters and a diameter of 1.75 meters, into the 1.9-billion-year-old bedrock. This is the first deposition hole intended for an iron-copper canister containing spent nuclear fuel—though test holes have been drilled at the site since 2022.
The Onkalo repository received a favorable safety assessment from the Radiation and Nuclear Safety Authority of Finland earlier in August.

Annual Conference
Monetary Award
$1,000
The Thermal Hydraulic Meritorious Service Award recognizes an individual for sustained and exemplary service to the nuclear thermal-hydraulic profession. Service can be in the form of:
Emphasis is placed on sustained, well-recognized, service contributions over a number of years but single exceptional one-time contributions may also be considered.
The award consists of an engraved plaque and a monetary award of $1,000. It is presented at the ANS Annual Conference.
This award was established by the Thermal Hydraulics Division in 2020.
The THD has offered in the past a service award and technical award (the current Technical Achievement Award). The service award was later abandoned in favor of emphasizing the importance of the TAA. Given the recent growth of THD and the increase of individual contributors, THD established the Service Award is in the best interest of our members. In fact, given a large number of participants in the activities of THD this award seems necessary to balance the current award offering of THD which is skewed toward technical contributions. This award highlights the importance of the continued service contributions of our members, aimed at the growth of the thermal-hydraulic profession, and forming the next generation of nuclear scientists and engineers.
This award recognizes an individual for sustained and exemplary service to the nuclear thermal-hydraulic profession.
