Sumario: | The quantity of iron shielding required for two LHC dumps was estimated at about 1500 tons. Possible sources of slightly irradiated iron shielding were considered, in particular, the ISR dipole yokes, which were stocked in the I2. Of rectangular form and weighing 22 tons each, they were well suited to the LHC dump geometry. Furthermore, they were to all intents and purposes non-radioactive. The preferred solution was to cut off four lifting pads and three support plates using arc/air equipment, seal temporarily each end with shutters, fit two lifting "anchor" pins, and fill with concrete. |
