  The LHC beam dumping system operated reliably during the Run 1 period of the LHC (2009 – 2013). As expected, there were a number of internal failures of the beam dumping system which, because of in-built safety features, resulted in safe removal of the particle beams from the machine. These failures (i.e. "false" beam dumps) have been appointed to the different failure modes and are compared to the predictions made by a reliability model established before the start of LHC operation. A statistically significant difference between model and failure data identifies those beam dumping system components that may have unduly impacted on the LHC availability and safety or might have been out of the scope of the initial model. An updated model of the beam dumping system reliability is presented, taking into account the experimental data presented and the foreseen system changes to be made in the 2013 – 2014 LHC shutdown.
