Great projects are carried out in collaboration:
Korea LILW, Repository, Wolsong Korea
AINS provided key expertise services covering training programmes, layout design, groundwater control, engineering barrier systems, rock engineering, site characterisation and technical design of the LILW facility. During the construction works, AINS was providing technical evaluation and licensing support for the repository in Korea during 2 years.
•Built 2006-2014, in operation since 13.7.2015
•$1.5 billion, roughly 400.000 m3
•Waste containers in silos (80 – 130 meters bsl)
•Six silos (diameter of 24 m and height 35 m) for 100,000 drums, a construction tunnel (1950 m), operation tunnel (1415 m), access shaft (207 m)
•AINS did 15 work packages during 2004-2014
”AINS has been involved in the project since very beginning of the design of the facility, since 2006. AINS has a frame agreement called ”Technical evaluation and licencing support for design of disposal underground silo” under which more than ten projects have been succesfully executed.”

LILW (VLJ) Respository, Olkiluoto, Finland
AINS provided the main design, general design and rock engineering design for TVO’s low and intermediate level (LILW) nuclear waste repository. AINS was responsible for the geological mapping and supervision of the rock engineering works during construction. AINS has also done several extension designs for decommissioning waste openings and analyzed the site monitoring results.
In operation since 1992 (nowadays half filled)
90.000 m3, silos’ depth 70–100 m
Operational waste from Olkiluoto NPP
Waste is packed into concrete containers
Two silos (diameter of 24 m and height 35 m)
An access tunnel (665 m), access shaft (57 m)
”Excellent budget control !
Good in taking custmer’s needs into account, helpfulness, availability, expertice, satisfaction with the design and schedule control. Co-operation is based on expertice and long term professional experience”
Liisa Heikinheimo, 3/ 2016
Posiva SNF Disposal Facility, Olkiluoto, Finland
Posiva spent nuclear fuel (SNF) disposal facility (DF) is the most advanced SNF repository project in the world. AINS has had roughly 400 assignments during the last 40 years for this DF and had a key role also in gaining construction license for the DF. AINS has widely contributed to for example site selection, technical design, long term safety analysis, cost control and public acceptance.
•Construction works started in 2004 and the facility will start operation around 2024
•650 MEUR, 1.317.000 m3, 250.000 m2 and 51 km of tunnels/shafts (without underground research laboratory)
•AINS contract value for design and safety evaluation has been annually 2-3 MEUR during the last decade
•an access tunnel 5 km and 4 vertical shafts, depth 465 m
“Unique expertise, high quality, commitment, team-spirit, can-do attitude by staff and management.”
Barbara Pastina, 4/2016
“Positive feedback for the AINS work through out the whole Posiva organization, especially the new developed method for the deliverable”
Juha Riihimäki, 11/2017
“Customer relationship once established and with mutual respect is functional and successful.”
Kari Koskinen 10/2018”
Deep Geological Repository, DGR, Czech Republic
The client SÚRAO procure AINS’s and PSOy’s knowhow, which is accumulated during the Finnish DGR project, for the disposal of high level waste (HLW). AINS advisory work includes updating siting strategy, developing of the disposal concept and DGR design, improving the Safety Case of the concept, environmental impact assessments and in increasing DGR acceptability.
•The site for DGR should be selected by 2025
•1.700.000 m3, depth 500 m, investment 1300 MEUR
•The above-ground area covers 29.5 hectares
•9000 tonnes of spent nuclear fuel (SNF) and 5000 m3 of other radiactive waste
•The services: 4 years, 2.75 MEUR
“I would like to thank you for great workshop! I got positive feedbacks.“
Lucie Hausmannová 22.3.2019 SÚRAO project manager and materials specialist, Czech Republic
Mizunami URL, Tono area , Central Japan
The only underground research laboratory URL in crystalline rock in Japan is the Mizunami URL, where a wide range of research has been done to build a firm scientific and technological basis for geological disposal. AINS developed a closure strategy & demonstration incl. monitoring for URL. AINS also reported the latest studies, laboratory tests, applications, experiences etc. in Finland related to colloidal silica grouting with respect to saline ground water effects and arranged a technical workshop.
•started in 2005
•diameter of both (main and ventilation) shafts is 6 m
•Two 1,000 m deep shafts and several drifts
•The geoscientific research will last for 20 years
“Thank you very much for your excellent work!
Thank you very much for your tremendous effort within the tight schedule! These findings shall reinforce the purpose and background of our project (for JAEA).”

Near Surface LILW Repository, Lithuania
AINS reviewed a design documentation for the repository for the low and intermediate-level (LILW) radioactive waste (RW). AINS focused on long-term safety, vault design and quality aspects of the review. AINS submitted recommendations so that State Nuclear Power Safety Inspectorate could take a decision on the issuing of a construction license.
•A landfill-type multi-barrier repository concept (complementary system of natural and artificial barriers)
•Modular-type with reinforced concrete vaults
•Waste provided by Ingalina Nuclear Power Plant
•Disposal volume of conditioned waste of 100.000 m3
