Japan Nuclear Cycle Development Institute (JNC) is developing a remote monitoring system using seismic and electromagnetic ACROSS (Accurately Controlled Routinely Operated Signal System) in the Horonobe Underground Research Laboratory (URL). The Horonobe URL project is devoted to the technological development for a safe geological disposal of high level radioactive wastes over a 20-year period from March 2001 in Horonobe-cho in northern Hokkaido, Japan. The purpose of installing a remote monitoring system is to monitor changes in the geological environment before, during and after the construction of an URL facility. The source and receiver system of electromagnetic ACROSS and the receivers of a seismic ACROSS will be installed in the fiscal year 2004, while the source of the seismic ACROSS will be transported from Tono Geoscience Center in 2005.
