Serious flood setback for TBM project in India
Assembly of the TBM was complete and launch was just a week away when disaster struck. An overtopping of the cofferdam completely flooded the inlet portal working site of the AMR tunnelling project near Hyderabad in India. Exceptionally heavy rainstorms charged the levels in the chain of Srisalem Reservoirs leading to rises in water levels by up to 3m in a short period of time.

Robbins leads India’s reintroduction to mega TBM advantages at AMR - TunnelTalk
India’s need for the advantages of TBM excavation is immense. Not for the labour saving benefits but for the speed and quality of construction by which TBMs can excavate long tunnels for hydro, irrigation, road and rail tunnels. India’s history with large scale TBM tunnelling however is limited and disastrous. The sorry saga of TBM drives for the Dulhasti and Parbati hydro schemes is recalled with much frustration by Indian engineers. Resorting India’s appreciation and confidence in large scale TBM tunnelling is a tough assignment and one that Robbins has accepted in full measure, starting with the AMR project in the state of Andhra Pradesh where it is working with lead India construction company Jaiprakash to ensure success of the longest, largest diameter, hard rock TBM tunnel in India’s history and claimed by Robbins as the longest in the world without intermediate access points. TunnelTalk visited the project to bring this report.

Yucca Mountain all but scrapped
Following 20 years of intense study, Yucca Mountain in Nevada has been recommended to the US Congress as the site for long term management and underground storage of the country's growing stockpiles of high-level radioactive nuclear waste. In February 2002, the Secretary of Energy recommended to the President that Yucca Mountain be developed as the first US repository for spent nuclear fuel and high-level radioactive waste. Endorsement the day after by President Bush launched the project on what will remain a long road to gaining Congressional approval and obtaining the many necessary permits before construction of the facility can continue and storage of the waste can begin.
