Radioactive waste disposal 957360 Seismogeological acceptance criteria for geological repositories for spent nuclear fuel V. Schenk, Z. Schenkova & P. Kottnauer, Natural Hazards, 10(1-2), 1994, pp 171-180. Qualitative geological acceptance criteria and quantitative seismological acceptance criteria for radioactive waste disposals are developed. The background material for the initiation of site selection and for its earthquake hazard assessment is discussed. A new comprehensive integrated safety analysis of the final underground disposal of spent nuclear fuel has been underway in the Czech Republic since 1991. In accordance with these seismogeological acceptance criteria regions for building underground final radioactive waste disposals are singled out in the Czech Republic. (from Authors) 957361 The hole story ANON, International Construction, 34(2), 1995, p 60. Describes the drilling rigs and equipment used to drill inclined boreholes up to 3 km deep at the Nirex site in Cmnbria, UK to investigate its potential for deep underground storage of radioactive waste. A new EDECO slim-hole drilling rig was used for open hole drilling and wireline coring. The 100t capacity rig features hydraulic power, mechanical pipe handling with automatic feed control, computer monitoring and recording of drilling progress, ground anchors, and ease of entry in hard rock formations.

Underground construction methods 957362 Station excavation into a production shaft P. Hickey & A. Oliver, CIM Bulletin, 88(990), 1995, pp 4245. In March 1993, Ram Raising Limited was faced with a challenge. Placer Dome Incorporated, Dome Mine Division, requested from Ram Raising that they design station excavation into the existing No. 8 shaft from No. 3 mine levels. This work had to be done without loss of production time in the underground department. This paper shows how, through innovative design and the full cooperation between client and contractor, a project of this nature can be completed successfully.

957364 Auffahren des Strassentunnels Puymorens (Driving the Puymorens road tunnel) M. Effier, O. E. Hoffman & V. Schenk, Felsbau, 13(1), 1995, pp 29-38. The Pyrenees extend over a distance of more than 400 km from the Mediterranean to the Bay of Biscay. Previously there were only two tunnels under the main ridge of the mountain range: the 4.6 km long Viella tunnel in the Val d'Aran, the upper course of the Garonne, and the approximately 3 km long Bielsa tunnel. The 4820 m long Puymorens tunnel was driven on the border between the Central and Eastern Pyrenees from November 1990 to January 1993. The tunnel runs at 1505 to 1565 m under the 1915 m high Col du Puymorens pass, so that the link from Toulouse via Foix, Axles-Thermes and Puigcera to Barcelona can be extended efficiently and with adaptation to the traffic. The portals of the two-lane road tunnel are situated in the over 20 m high fan structures constructed outside the tunnel. They make the underground structure recognisable as an engineering structure in the landscape and are a feature of the environment. The concave exposed side in the north is designed to conform to the narrow valley termination of the Ariege, whereas the convex structure in the south, in front of which is the tollgate, aims to symbolise an opening into the gentler slopes of the valley of the Carol. The tunnel has a carriageway clearance profile of 7.60 m x 4.50 m and an excavation cross-section of about 86 m 2. It was driven from opposite directions in accordance with the principles of the New Austrian Tunnelling Method (NATM).

Maxtak, Felsbau, 13(2), 1995, pp 64-70. In the years between 1983 and 1995 13.8 km of running tunnels and stations of the underground lines U3 and U6 were constructed in Vienna. According to the New Austrian Tunnelhng Method (NATM) 7 kin of tunnels were designed and executed. The ground is build up of a wide range of waterfilled soil. But NATM has been used both economically and safe in this difficult ground. (English summary) 957366 Grecian yearn for C & N E. Lane, International Construction, 34(2), 1995, p 67. Describes the Christiani & Nielsen contract to install the Preveza-Aktion immersed tube road tunnel in Greece. Seismic conditions are a major problem in the area. The 1 km long, 10.6 m wide by 6 m high single bore tunnel will be set in a predredged seabed trench. The reasons for selecting this particular tunnelfing method for the project are discussed.

The two 400 m long road tunnels which now carry the A20 through Round Hill in Kent - part of £65 million improvemerit scheme associated with the UK Channel Tunnel terminal - are seen by many as a milestone in the history of British tunnelling. The environmental sensitivity of the area resulted in the UK's first road tunnel to be designed and built following the basic philosophy of the New Austrian Tunnelling Method (NATM). Despite unexpectedly poor ground conditions, the method of incremental support and observa-
