The Mizunami Underground Research Laboratory (MIU) project is being pursued by the Japan Atomic Energy Agency (JAEA) to enhance the reliability of relevant disposal technologies through investigations of the deep geological environment within the host crystalline rock at Mizunami City in Gifu, central Japan. The project consists of major research areas, "Geoscientific Research", and proceeds in three overlapping phases, "Phase I: Surface-based investigation Phase", "Phase II: Construction Phase" and "Phase III: Operation Phase". The present report summarizes the research and development activities planned for fiscal year 2013 based on the MIU Master Plan updated in 2010.

An agreement was concluded among MEXT (Ministry of Education, Culture, Sports, Science and Technology), Tottori Prefecture, Misasa Town and JAEA (Japan Atomic Energy Agency) on May 31st, 2006, aiming at resolving the problem due to the waste soil deposited at JAEA's Katamo Waste Soil Yards. Based on the agreement, a plant was constructed in the land JAEA rented form the Misasa Town to manufacture bricks from the micture of the waste soil and additives such as cement. The plant manufactured about 1.45 million bricks during the period of operation between April 28th, 2008, and December 13th, 2010. This report summarizes the outline of the brick manufacturing plant, the results of trial and pilot operations and the performance of full-scale operation.

Shotcreting is currently underway in the south research access tunnel 500 m underground at Mizunami Underground Research Laboratory. The use of the low alkaline super shotcrete spraying method, which makes it possible to obtain high strength and high stiffness quickly after spraying while minimizing an environmental impact, is being considered as a means of stabilizing an excavated rock surface whose condition is rapidly deteriorating. For the purpose of evaluating the applicability of the method to the shotcreting work currently in progress, a verification field test was conducted. This paper briefly reports on the test.
