Abstract
Posiva is a Finnish nuclear waste management company with the duty to take
care of the high-level nuclear waste produced in Finland. Pursuant to the
Decision-in-Principle of 2001 Posiva has moved to the phase of underground
characterisation of the repository site. The main objective of this phase is to
confirm the suitability of the Olkiluoto site by investigations conducted
underground. A programme of monitoring has been launched as part of the
investigations and to follow the changes occurring within the site due to the
construction. The programme of monitoring started in the year 2004, one year
before the construction work. Baseline monitoring was carried out prior to the
construction phase and the results gained from monitoring during construction
phase are compared to the baseline data. Rock mechanics, hydrology,
geochemistry, environment, and the use of foreign materials are included the
monitoring programme.
Keywords: monitoring, high-level nuclear waste, hydrology, rock mechanics,
geochemistry, environment, foreign materials, underground rock
characterization facility.
