Helium compressor aerodynamics is challenged by the characteristically narrow and numerous-stage flowpath which enhances loss effects of blade surface and end wall boundary layers, secondary and clearance flows, and any occurrence of flow separation and stage mismatch. To meet efficiency and reliability requirements of nuclear application, baseline and advanced aerodynamic design techniques are incorporated with intent to mitigate the flowpath adverse working condition and losses. Design validation is carried out by test and test-calibrated 3D viscous CFD analysis on a subscale model compressor. The data and computational insights of overall performance and internal flow behavior are used to establish a performance model based on Reynolds number. The model applicable to all geometrically similar designs shows sensitive responses of aerodynamic efficiency to Reynolds number and surface roughness.

The Horonobe URL Project started in 2000. Research and development activities are planned over three phases, that will span a total duration of about 20 years: the 1st surface-based investigarion phase (6 years), the 2nd URL construction phase (8 years) and rhe 3rd operation phase (12 years). Geological, geophysical, geo-mechanical, hydrogeological, and hydro-geochemical investigations have been carried out during the surface-based investigation.

The Horonobe Underground Research Laboratory (URL) 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 sedimentary formations at Horonobe, northern Hokkaido. The project consists of two major research areas, "Geoscientific Research" and "R&D on Geological Disposal", and proceeds in three overlapping phases, "Phase I: Surface-based investigation", "Phase II: Construction" and "Phase III: Operation", over a period of 20 years. The present report summarises the results of the Phase I geoscientific research carried out from March 2001 to March 2005. Integration of work from different disciplines into a "geosynthesis" ensures that the Phase I goals have been successfully achieved and identifies key issues that need to be addressed in the Phase II/III investigations.
