4. SPS • EL cabling works in progress • The preparation of LSS1 for the irradiated cable campaign has begun.  The TIDH and the TIDGV have been disconnected (using the robot to reduce the dose) and moved by transport to the new storage area in ECX5 (the equipment remained in the tunnel) • EPC are in the process of removing and replacing 8 transformers outside BA3 (between BA3 and the CCC)  They have currently removed all of the transformers and installed 2 of the new ones. • Civil engineering have installed a test support in TT10 The test was successful and they have now ordered the remaining supports needs (around 25)  they are scheduled to arrive mid-August. • All other works progressing on schedule.
