Great projects are carried out in collaboration:
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).”

Nuclear Waste Disposal and Environment Department, JAPAN
LILW Repository for UK, United Kingdom
The aim of AINS project was to collate the information on existing low and intermediate level (LILW) nuclear waste disposal silos in different countries (AINS has designed most of the silo type LILW repositories) in crystalline bedrock. Information gathered added the client understanding, after which a decision on whether to retain silo disposal in the range of layout options can be made.
•Disposal of low heat generating wastes (LHGW)
•Possible both high level waste and LILW waste to the same facility
•200-1000 metres deep, the area several square km
•A national geological screening was started in 2015
”It is always a pleasure to work with staff at AINS. I particularly welcome the combination of professional behaviour and friendly, personal engagement.” Excellent in all areas (quality of documents, helpfulness, communication, availability, expertice and schedule & budget control etc.).

Canada HLW Repository, Canada
NWMO is implementing Adaptive Phased Management (APM), the centralized isolation of SNF in a repository. AINS ALARA assessments ensured that the worker dose rates are within the regulatory limits and identified changes for optimization of design and operation. AINS FMEA analysis have been used to identify potentially hazardous events and accidents during the operation.
•6 km2 HLW repository
•depth of 500 m
•advancing 3 reference concepts: the Mark I, II, III
•The repository will also include areas for offices, maintenance, services, monitoring and testing
•The investment is 7-8 billion CAD.
“The technical expertise of the team in preparing the preliminary ALARA and preliminary hazard assessment documents and the flexibility of your company in accommodating our needs are greatly appreciated. “
